Fertilize soil or land
The flower proverb is well said, clear peony, muddy peony. What does Qing mean? There are a few words in "Flower Mirror" that can be used as a footnote: it is freezing in December and can only be drowned by pig manure. After the vernal equinox, don't fertilize it. Wait until bloom before using dry fertilizer. Watering is especially forbidden in June, which will damage the root system and there will be no flowers in spring. It can be seen that talking clearly does not mean only watering without fertilization. Some people are afraid to fertilize because they say so, which is a misunderstanding of what they say. Fertilization experience is: base fertilizer should be sufficient, compost and cake fertilizer should be applied when planting. Manure. Cover the fat with soil. Top dressing should be controlled, and it can be applied once after flowering in spring, and the fertilizer must be decomposed. Not too thick. No topdressing in summer. Winter fertilizer is the most important fertilization, and winter fertilizer should be combined with soil cultivation. It is not suitable to apply thick fertilizer to new peony, especially to avoid pouring thick fertilizer, otherwise the fleshy roots will rot and die. The source of nutrients is mainly base fertilizer. Although it is in the growing season after flowering, it is still not suitable to apply liquid fertilizer. After planting for one year, solid base fertilizer should also be mainly applied in winter.
water
Peony should not be watered too much, and it is generally not watered in winter. After May, the weather became hotter and hotter. Dry land can be properly watered if it is dry, but it should be dry and not wet. Water the soil only when it is dry. Water accumulation should be prevented in showers and rainy seasons to avoid damaging plants. Storms or persistent rains often harden the soil. When the land is dry after the rain, we must loosen it. Loosening soil in time can improve the air permeability of soil. Peony roots should be buried vertically, and the scarification should be deep. Subsoil topsoil at least three times a year, once after flowering in spring, once after rainy season in summer and once after typhoon and rainstorm in autumn.
Flowering management
If the terminal bud of the main branch is not a bud, but a leaf bud, it should be picked in time to avoid unnecessary growth and affect flowering. Peony branches are fragile. When a flower first blooms, because the flower head is heavy, the branches tend to bend and break easily when encountering strong wind. Therefore, thin bamboo pieces can be used to tie the support, which can not only prevent it from breaking, but also increase the appearance. After the flowers wither, cut off the pedicels to prevent the seeds from setting, so as to ensure the vigorous growth of the plants.
Peony should be covered with grass in winter to prevent cold, and swept and covered with grass in March when the weather is warm.
Value of Oil Peony | Planting Technology of Oil Peony
Peony is a treasure all over the body, especially after the important value of peony seed oil was recognized by the Ministry of Health, the production of oil peony officially started, and it is still too early to say that it is an industry. As mentioned above, oil peony is a hardcore crop. Once planted, it will not change for decades, so the idea of choosing improved varieties cannot be shaken. At present, the price of oil peony seedlings runs at a high level. At present, most enterprises involved in the early stage rely on selling seedlings to make profits to support their development, but it is unrealistic to make profits by producing peony seed oil. Experts remind that before planting peony to extract oil, we must think clearly about several problems. First of all, we should consider whether the input-output ratio can hold up. Peony oil exchange is a high-input and long-term project. The risks in the early stage must be fully considered. If you invest only three to five years, there will be no output. Can your capital chain hold up? Generally speaking, the land rent above 800 yuan per mu is not suitable for large-scale self-planting in principle, because oil peony has only a single color, short flowering period (only about 15 days), and the input-output cycle takes four years. If the planting technique is not too hard, the cycle will be longer. Of course, it is another matter to cooperate with ecological agriculture or leisure landscape in the suburbs of big cities.
Second, it is necessary to investigate whether there are supporting resources to borrow from the project location. Heze is the largest peony planting base in the world, with an annual output value of only 300 million yuan, while Luoyang peony is only used for sightseeing, with an annual output value as high as 654.38+0 billion yuan. Although its planting area is far less than Heze, it has the cultural heritage of the ancient capital of the Nine Dynasties, and is supported and integrated by tourism resources such as Shaolin Temple and Longmen Grottoes, forming the unique characteristics of Luoyang Peony. You choose oil peony, can you make your own characteristics and brand? Without characteristics, what about the future market?
Third, it is necessary to investigate whether planting oil peony is in line with the local industrial direction. As woody oil, oil peony involves many policy projects such as returning farmland to forest, afforestation in barren hills, soil and water conservation, new agricultural transformation, under-forest economy, medicinal materials, forestry cooperatives, etc. Different regions have different support policies. Before planting oil peony, you need to know the local industrial direction, investigate at provinces, cities and counties step by step, and understand the policies of governments at all levels related to forest and agriculture, so that your oil peony project can be included in the government planning, which can not only reduce the financial pressure, but also help the local government to complete the established industrial development and achieve a win-win situation.
Fourth, we must ensure that technology is in place and output is guaranteed. The first step to develop oil peony is planting management. It is necessary to ensure that good varieties and strong seedlings are planted, and at the same time strengthen planting management to improve the survival rate of seedlings. Zhang Yanlong, director of the Peony Engineering Technology Research Center of the State Forestry Administration, said that although peony is highly resistant, it is planted in flowers and medicines, and basically no pesticides are needed. Even if you are sick, it is enough to strengthen pruning in autumn. However, if it is planted as an oil crop in a large area, it is necessary to strengthen the prevention of diseases, otherwise it will affect the yield and quality.
Fifth, we should consider the way of realizing oil peony after planting. At present, many peony seed oil production is still in the stage of small workshop processing. An automatic production line of 10,000 tons of peony seed oil in Heze City has not been put into production due to insufficient raw materials, and the brands of peony seed oil in the market are mixed. If an enterprise has mastered the core technology of peony deep processing, can create high value-added products and create its own unique brand, then joining the oil peony industry will have the basis for survival, profit and growth.
How to fertilize potted lotus lamp? Pay attention to the operation details!
Fertilization method of potted lotus lamp
Growth period: the growth period of lotus lantern is from April to 10, and the growth period is in summer. In order to apply fertilizer reasonably in the whole growth period, the ratio of potassium: phosphorus: nitrogen = 1: 1: 1 can be adopted and applied once every 6-8 days.
Seedling stage: the amount of nitrogen fertilizer should be increased at seedling stage, and the contents of potassium and phosphorus should be increased at seedling stage, and fertilizer should be applied once every 1 week.
Precautions for operation
The requirements of lotus lamp on fertilizer should not be too high, but it should also maintain its nutritional balance.
Fertilizer must be diluted before use. Too thick fertilizer will make its roots rot, and in severe cases it will cause death. You can make the fertilizer too thin but not too thick.
If it is cultivated in the north, some ferrous sulfate can be added to the fertilizer water, because the water in the north is alkaline, and the soil for cultivating it should be kept in a slightly acidic state.
Very sensitive to salt, you must avoid it when choosing fertilizer.
In the process of fertilization, we must be careful not to let flowers and leaves touch the fertilizer, but also avoid touching the roots to avoid unnecessary harm to plants.
Although it needs moist soil, it should not be too wet, which will rot its roots, so it must be paid attention to when fertilizing.
If the weather is bad, don't forget to postpone fertilization.
Planting method of bodhi tree | Matters needing attention in planting bodhi tree
Bodhi trees have moderate resistance to sulfur dioxide and chlorine, and strong resistance to hydrofluoric acid, which is suitable for greening in polluted areas. At the same time, it is an excellent ornamental tree species with swollen branches, tall trees, lush foliage and broad crown, which is suitable for courtyard street greening. In addition, bodhi tree is a traditional Chinese medicine for treating asthma, diabetes, diarrhea, epilepsy and stomach diseases. Today, I will briefly introduce the planting methods and precautions of bodhi trees for you.
Planting method of bodhi tree
For seed propagation, it is necessary to select strong mother plants that are more than 10 years old, collect the seeds when the fruits are red and black in1month, knead the collected fruits repeatedly, remove the meat residue and dander, take out the seeds, and sow them after being slightly dried. Generally, sand beds are used for sowing seeds. Before sowing, slightly compact the bed surface with small wooden boards, level the bed surface, and evenly scatter the seeds on the bed surface. When sowing, seeds should be prevented from overlapping into small balls, and each seed should be scattered on the bed surface as much as possible.
After sowing, cover the seeds with a thin layer of soil with a fine screen, preferably just the seeds. After sowing, build a shade shed with straw or sunshade net to reduce the evaporation of water in the seedbed and keep the bed surface moist. At the same time, chemical substances that kill ants are scattered around the sand bed to prevent the seeds from being hurt by ants and crickets when they germinate. Because the seeds of bodhi trees have no dormancy habit, they can germinate and emerge in about 10 days after sowing, and the seeds will germinate one after another.
When the germination is about half, uncover all the straw, shade it properly, and pour enough water every morning and evening. When the seedlings grow to 24cm, they should be transplanted into 10cm 12cm nutrient bags filled with soil (topsoil with high humus content) in advance for culture. After the seedlings are transplanted into nutrient bags, they should be shaded by shading nets and watered in the morning and evening. After the seedlings resumed growth, the roots were watered with 0. 1% urea aqueous solution and Norwegian compound fertilizer every 7 days.
Sprinkle a small amount of water after root irrigation (sprinklers can be used in qualified nurseries), which is beneficial to the seedlings to absorb water and fertilizer. When the seedlings grow to about 15cm, the concentration of water and fertilizer can be increased to 0.2% 0.3%. At the same time, take corresponding measures to prevent the occurrence of diseases. When the seedlings grow to 3050 cm, they can leave the nursery. Bodhi branches are also easy to survive by cutting. A robust 8 15-year-old mother plant can be selected in spring or autumn.
Branches with full axillary buds were selected from the mother plant and cut into cuttings (diameter about 0. The semi-lignified part is about 65438 05 cm, which is used for cutting propagation. The row spacing of cuttings is 5cm 10cm, and the cutting depth is about 3cm. After cutting, put on a small bow shed, cover it with white plastic agricultural film, and keep the front and rear ends ventilated. Spray water several times a day to ensure the shed.
After cutting, spray the cuttings with 0. 1.25% 0.2% broad-spectrum bactericide (such as chlorothalonil and carbendazim) solution. ) once every 7 days to prevent cuttings from rotting under high temperature and high humidity. Roots can grow in about 10 days. Bodhi trees can also be cut with big branches. Strong branches with a diameter of 65,438+0,065,438+0.5 cm and a length of 65,438+0.52.5 m can be cut and buried in the soil for 2030cm, and can take root after 20 days.
Matters needing attention in planting bodhi tree
Bodhi seedlings are easily infected with damping-off and black spot. Chemical control can be carried out by spraying 80% mancozeb wettable powder 0. 167% solution, or 60% carbendazim and 75% chlorothalonil 0. 125% solution, or spraying two mixed solutions every 7 days 1 time, three times in a row.
Aphids and moth larvae harm terminal buds and young leaves, especially aphids, and often cluster on the back of young leaves of seedlings to feed on mesophyll. Chemical control can be achieved by spraying 90% trichlorfon 0. 125% solution or 40% omethoate 0. 1%0. 125% solution on the front and back of young leaves.
