What is an agricultural ecological park? The agricultural ecological park adopts the ecological park mode, which carries out agricultural layout and production in the sightseeing park, and integrates agricultural activities, natural scenery, scientific and technological demonstration, leisure and entertainment, environmental protection, etc. To achieve the unity of ecological benefits, economic benefits and social benefits. Agricultural ecological park, also known as agricultural leisure park, refers to the agricultural management with the purpose of utilizing pastoral landscape, natural ecology and environmental resources, combining agriculture, forestry, fishery and animal husbandry production, agricultural management activities, rural culture and family life, providing national leisure and enhancing national agricultural and rural experience; It is a new industrial park integrating tourism, agricultural efficiency, greening, beautification and environmental improvement. We have taken more than 2,000 mu of land in Lishui, Changzhou, and are going to build an agricultural ecological park. The overall planning of agricultural ecological park is the most important, which should fully reflect local conditions, comprehensively plan and design, cultivate fine products, create a theme image, give consideration to benefits and realize sustainable development. Functionally, according to the nature of resources, landscape characteristics and existing environment, on the basis of maintaining the integrity of the original natural terrain and original ecological park, combined with future development and objective needs, appropriate design is adopted to realize the functional zoning of the park, and ecological agriculture demonstration zone, sightseeing agricultural tourism zone and popular science education functional zone can be set up according to local conditions in the design. The whole park is divided into four parks: 1. Eco-agriculture Demonstration Park Eco-agriculture Demonstration Park adopts a variety of eco-agriculture models for layout, aiming at establishing an agricultural ecosystem that can rationally utilize natural resources, maintain ecological stability and maintain high efficiency, improve agricultural productivity, obtain more grain and other agricultural and sideline products, realize sustainable eco-agriculture, show agricultural structure adjustment and industrialization development in marginal areas, and embody the characteristics of eco-tourism. Eco-agricultural demonstration area is the core part of ecological park design, the main benefit source and demonstration area of ecological park, and the foundation of its survival and development. The planning and design of eco-agricultural demonstration area should be guided by ecological principles and follow the laws of material circulation and energy flow in the ecosystem. The types of eco-agriculture used in park design include producers, consumers and decomposers. Eco-agricultural demonstration park is mainly reflected in the demonstration. What kind of agricultural products do you plan to grow? Grain crops are mainly rice, corn, cereals and so on. The cash crops are mainly cotton, fruits and vegetables. Animal husbandry mainly focuses on raising chickens, sheep and pigs. In the planning of ecological park, the ecological agriculture type of "animal and plant * * * system" in paddy field ecological zone adopts the growth mode of rice, fish and duckweed; The orchard ecological zone adopts the type of "three-dimensional planting" ecological agriculture, and adopts the mode of combining orchard with breeding; The design of fish pond ecological zone adopts the type of "food chain and processing chain ecological agriculture"-the planting and breeding mode of combining pigs, ducks, fish and grass. The type of ecological agriculture should make full use of the biological relationship of various organisms, string all ecological elements into a food chain, transform each other, and make full use of energy and matter, thus forming an ecological cycle of benign material energy, reflecting high ecological and economic benefits. In addition, in order to improve the economic benefits of the ecological park, the vegetable growing areas in the ecological park adopt large-scale industrialized production mode. It not only has the advantages of high production efficiency, strong industrial driving force, centralization and unification, but also has a demonstration and reference function for other agricultural industrialized enterprises. The flower cultivation area mainly produces all kinds of edible and ornamental flowers for tourists to taste, appreciate and buy. Edible fungi center is both a producer and a decomposer in the planning of ecological park, which embodies the function of making full use of waste. After scientific planning, the ecological park will take ecological agriculture as the main core content of "eco-tourism" of the ecological park, which embodies various functions of "green, ecological and demonstration" and can become the tourism boutique and leading product of the sightseeing agricultural ecological park. 2. Sightseeing Agricultural Sightseeing Park The planning of sightseeing agricultural ecological park will closely focus on agricultural production, make full use of rural landscape, local ethnic customs and local culture, and develop unique agricultural and sideline products and tourism products on the basis of embodying the beauty of natural ecology for tourists to sightseeing, sightseeing, tasting, shopping, participating in farming, leisure, vacation and other activities to form a distinctive "sightseeing agricultural sightseeing park". 2 1 century, with the change of human production and lifestyle and the deepening of rural urbanization and urban-rural integration, agriculture gradually shifted from traditional production forms to landscape, ecology, health, medical care, education, sightseeing, leisure and vacation, so ecological fever, rejuvenation fever and leisure fever became the pursuit and desire of citizens. The new design of the ecological park pays attention to the combination of agriculture, ecology and tourism, and uses pastoral landscape, agricultural production activities, rural ecological environment and eco-agricultural business model to attract tourists to watch, taste, exercise, farmhouse experience, fitness, scientific investigation, environmental education, vacation and shopping. Break through the fixed tourist source channels, attract tourists from surrounding cities to stay for a short time on weekends and holidays with special tourism projects close to nature, maximize the use of resources and increase tourism income. The planning of ecological park is based on the premise of fully developing agricultural resources and agricultural products with sightseeing value, with the theme of green, health and leisure. There will be a flower promenade, a wildfire park, a green restaurant, a green gift shop, a farmhouse activity park, a fishing area, an agricultural workshop, an open-air teahouse, an ecological park, a Xatu forest and other leisure and entertainment places in the park, so that visitors can enjoy the pastoral scenery in a perfect ecological environment. In the near future, the ecological park is planned to be an eco-agricultural sightseeing park focusing on fruit and flower cultivation, integrating leisure, entertainment, viewing and work experience. The ecological park can be divided into three functional areas, namely, recreation area, planting area and local customs area. There is an exhibition center in the entrance business circle, which focuses on the local customs and local characteristics, the initial processing of agricultural products, the display of agricultural tools, the historical evolution of villages and the introduction of special agricultural products. The special agricultural products processing technology exhibition area has pickles curing technology and rice cake processing technology. Planting areas are divided into fruit and flower ecological park, botanical garden and modern agricultural area. The fruit and flower ecological park mainly grows pears, grapes and strawberries. Considering the needs of tourists in different seasons, persimmons, oranges, peaches and other fruits have been added. The Botanical Garden grows various kinds of ornamental plants, and the colors, shapes and seasons of the tree species are coordinated, and small planting areas such as Gui Huayuan, Meiyuan and Guangyu Garden are divided. Modern agricultural area is a display area of modern agricultural planting techniques and agricultural products. In the near future, greenhouse vegetables are mainly planted, and it can be developed into a popular science base in the long run. In the local customs area, farmhouses and ponds are used to create local landscapes, and waterfowl such as poultry, crayfish and fish are stocked for tourists to capture and experience their work, fully display the characteristics of farmhouse music and reflect local customs.

3. Green Food Production Park Under the general trend that "green consumption" has become the overall consumption of the world, the planning of the ecological park should further strengthen the planning of the origin of organic green agricultural products, adopt clean production methods to produce organic agricultural products in the organic planting mode, and pay attention to transforming organic agricultural products into organic foods to form brands. The Great Development of Ecological Agriculture The so-called ecological agriculture refers to protecting, cultivating and making full use of natural resources, preventing and reducing environmental pollution, forming a virtuous circle of agriculture, forestry, animal husbandry and by-fishing, and using modern science and technology to maintain the stable development of large agriculture. Green food production park is a form of ecological agriculture. The ecological park engages in natural farming, and the technology is very simple and easy to master, and there is almost no need to inject and feed medicine. Free-range chickens and rabbits run and chase in the orchard, restoring their original nature, thus strengthening their physique and improving their immunity. At the same time, the chicken destroyed the fruit of the forest and provided high-quality organic fertilizer, which made the forest and grass particularly lush and enough for rabbits to eat. Planting fruit trees and trying to plant pasture in the ecological park, making full use of the upper and lower structural space; Raising Chai chicken can not only control weeds, reduce pests and diseases, but also provide organic fertilizer for fruit trees. At the same time, free-range feeding of Chai chicken can also bring a lot of income and increase the output of fruit trees. Leaves and grass are used for biogas fermentation, and biogas fertilizer is used for fertilizing fruit trees in vegetable fields. Organic fertilizer is pollution-free, which increases the constant of fruit trees and saves the consumption of electricity and gas. At the same time, it has also formed a circular organic ecological park, which is really killing two birds with one stone. Implement the trinity planting mode of "biogas-biogas harvesting", use biogas energy to produce vegetables, and gradually build a pollution-free vegetable and fruit production base. Develop the combination of agriculture and animal husbandry. Develop contract agriculture and animal husbandry, sign recycling contracts with food companies, develop fruit trees and free-range chicken, and promote a new ecological three-dimensional breeding model of "planting grass under trees, raising chickens on grass and fertilizing chicken manure on trees". In order to avoid destroying vegetation, according to the characteristics of Chai Chicken's successful life, a "mobile henhouse" was built and the feeding method of "district rotation" was adopted.

4. Popular Science Education and Agricultural Science and Technology Demonstration Park conducts environmental protection education and popular science education for tourists and primary and secondary school students by building agricultural museums and exhibition halls in the park. At the same time, in order to meet the needs of China's agricultural development and agricultural structure adjustment, the park should be planned as an agricultural technology exchange center, a training base and an internship base for college students, so as to reflect the popular science function of the sightseeing agricultural ecological park and further create the image of fine tourism products. The development of sightseeing agriculture and agricultural science popularization is unified, and tourism science popularization is the unified product of sightseeing agriculture and agricultural science popularization. Tourism popular science is a new type of popular science that develops and utilizes agricultural resources with modern enterprise management mechanism. Its introduction will solve many bottleneck problems that plague the development of modern sightseeing agriculture and popular science in China at present, alleviate the heavy pressure of too many agricultural popular science objects in China, and create a good environment for the development of agriculture and popular science in China. Tourism science popularization planning should follow the principles of knowledge, science and technology and interest. For example, popular science education centers such as agricultural science museum and modern agricultural science and technology Expo area can be set up in the ecological park to introduce agricultural history and agricultural development status to tourists, popularize agricultural knowledge and strengthen environmental education. You can also set up a modern agricultural science and technology research center in the modern agricultural science and technology Expo area, and cultivate various crops by bioengineering methods to form characteristic agriculture. On the one hand, this ecological park can provide a base for popular science education in local and surrounding areas, a place for popular science education in universities, primary and secondary schools, and a place for various exhibitions, large-scale agricultural technology exchanges, academic conferences and agricultural technology training. Other planned roads in the ecological park are planned in a unified way according to the idea of garden planning and design, starting from the use function of the garden, according to the topography, landforms, functional areas and scenic spots distribution of the ecological park, and combined with the needs of garden management activities. The layout of the garden road will not affect the operating environment of the agricultural ecosystem in the park, nor will it affect the harmony and beauty of the scenic spots in the park. The garden road layout mainly adopts the natural garden layout, which makes the landscape in the ecological park beautiful and natural, and highlights the characteristics of the combination of agriculture and nature in the ecological park. The main road in the park is about 5 m wide, which is used for tram traffic and tourist distribution; Secondary roads connect various building areas and scenic spots; Dedicated lanes are used for garden management; Walking trails and mountain single lanes are mainly built around the ecological park, with a width of1.2 ~ 2 m. Water supply and drainage and irrigation engineering planning The ecological park mainly produces organic agricultural products, and agricultural production in the park needs a perfect irrigation system. At the same time, considering the environmental protection and the drinking water demand of tourists and gardeners, the water supply and drainage system is planned. In the planning, natural slopes and culverts with undulating terrain are mainly used to discharge rainwater into nearby water bodies; All artificial water supply and drainage systems should be buried with concealed pipes to avoid damaging the ecological environment and garden landscape; Agricultural products processing plants and domestic sewage discharge pipes are connected to the urban domestic water system, and shall not be discharged into the ground or ponds of the park to avoid environmental pollution. The greening design of the park The greening planning in the ecological park is based on the consideration of not affecting the operation of eco-agriculture and the functional requirements of the park, and combining with the requirements of plant landscaping, tourist activities and the landscape layout of the whole park. Perennial flowers and lawns are used for greening the flat land and hillside around the buildings in the whole park (except agricultural planting areas); Main roads and auxiliary places such as ecological parks (restaurants, science and technology museums, etc.). ) mainly planting flowers and foliage trees. Evergreen trees account for 70%~80% of the total greening trees in the park, and deciduous trees account for 20%~30%, so as to ensure that the park is evergreen all the year round. In short, the purpose of plant layout in the whole garden is to realize the coordination and unity of crops and green plants in various scenic spots and avoid negative effects (such as green plants and crops competing for external natural conditions, etc.). The main facilities we will equip are the high-tech greenhouse planting education area: dozens of large greenhouses, advanced automatic control devices and soilless culture systems, which cultivate all kinds of pollution-free vegetables all over the world, which are colorful, just like being on a farm abroad. Foreign vegetable growing areas: More than 100 kinds of famous foreign vegetables and overseas high-tech agricultural culture will surely amaze you.

1. Nutrition of Chai Chicken

Chickens feed on grasshoppers, grasses, vegetable leaves, grass seeds and whole grains, and drink natural water such as rivers, streams and shallow lakes. The produced Chai Chicken and free-range eggs are naturally fragrant, and the absolute free-range eggs have high protein content, and the yolk color is naturally yellow. It is rich in calcium ions and more than a dozen amino acids needed by human body, and does not contain any hormones and antibiotics. It is a pure natural green food and a brand-new nutritious egg suitable for all ages. Mountain whooping cock is young, strong and pure in meat flavor. Free-range eggs and green shell eggs are naturally yellow in color, good in taste and have natural fragrance. It is rich in calcium ions, potassium ions and more than a dozen essential amino acids, and does not contain any hormones, antibiotics and pesticides. This is a pure green food.

2. The benefits of biogas digesters

There are many benefits of setting biogas, mainly including the following aspects:

(1) Setting up biogas is beneficial to solve rural energy problems. A family of 3-4 people can build a 10 cubic meter biogas digester. As long as the fermentation raw materials are sufficient and properly managed, the fuel problem of lighting and cooking can be solved.

(2) Setting up biogas is conducive to promoting the development of agricultural production. After the establishment of biogas, a large number of livestock manure is added to the biogas digester for fermentation, which can not only produce biogas, but also produce a large number of high-quality organic fertilizers, expanding the source of organic fertilizers. All the crops applying biogas fertilizer not only enhanced the drought resistance and frost resistance, but also improved the survival rate of seedlings. The application of biogas fertilizer not only saves the spraying amount of chemical fertilizer and pesticide, but also is beneficial to the production of green pollution-free food.

(3) Setting up biogas is beneficial to the development of animal husbandry. After running biogas, it will help solve the contradiction of "three materials" (fuel, feed and fertilizer) and promote the development of animal husbandry.

(4) Biogas can improve sanitary conditions. All farmers who have built biogas digesters realize that using biogas as fuel is smokeless, clean and convenient. Some excrement, garbage and domestic sewage are good raw materials for biogas fermentation. As these raw materials enter the biogas digester, bacteria and parasite eggs are killed by closed fermentation in the biogas digester. Thereby improving the environmental sanitation conditions in rural areas and benefiting the health of people and livestock.

(5) Setting biogas is beneficial to protect the ecological environment. Setting up biogas can solve farmers' fuel problem, reduce deforestation and the damage of cattle and sheep to Shan Ye, protect forest and grass resources, promote afforestation development, reduce soil erosion and improve agricultural ecological environment.

(6) Setting up biogas is beneficial to the liberation of labor force. After biogas is set up, a large amount of labor that farmers used to spend collecting firewood and transporting coal can be saved and put into the front line of agricultural production. By using biogas, rural women are liberated from traditional cooking methods, saving cooking time and reducing housework.

In addition to sightseeing, collecting, reflecting farming and enjoying the local flavor, the agricultural ecological park also accommodates functions such as catering, entertainment and popular science education. It is a comprehensive park with crops, horticultural crops, flowers and so on. , so that tourists can not only enjoy the pastoral fun, but also enjoy, taste and buy. This plan emphasizes the combination of project setting with local folk customs and farming culture, and attracts residents in surrounding cities with cordial, true and simple feelings. Emphasize the participation and interaction of project setting, arrange fruit picking, poultry catching, rice cake making, pickled vegetables and other projects to increase the visibility of park activities and reflect local flavor.

In short, by introducing various advanced high-tech agricultural technologies from abroad, we will vigorously develop high-tech agriculture, environmental protection agriculture, garden agriculture and ornamental agriculture, pursue green ecological construction and develop together with the environment. Reduce pollution, produce various green products such as foreign fruits and vegetables, sell green products outside the province, sell them directly overseas, and open up domestic and foreign markets. Let agriculture move towards internationalization, networking, specialization and diversification, and let our agricultural ecological park project become a model pioneer of agriculture in China and a world-leading model project.
