What agricultural activities are there at the beginning of spring?
First, animal husbandry.
Pay attention to keep the fence warm.
Do a good job in fattening cattle, and appropriately increase bran feed while feeding green hay.
Long-haired rabbits have strong thermal insulation ability, but in the process of plucking, we should pay attention to plucking only half of the hair to prevent catching cold and getting sick.
Special attention should be paid to the insulation of young livestock and poultry to prevent gastrointestinal diseases and respiratory diseases.
It is forbidden for livestock to drink frozen water or cold water. It is better to use warm water or well water.
Do a good job in the prevention of livestock epidemic sources abroad, especially around the Spring Festival, the number of live pigs on the market has increased, and special attention should be paid to the epidemic dynamics in the circulation field and livestock trading market. At the same time, if pigs, cattle, sheep and other cloven-hoofed animals and livestock have not been vaccinated, livestock vaccines should be supplemented.
Second, vegetables
1 spring seedling raising of cucumber and vegetables in greenhouse
Before and after beginning of spring, cucumber was sown in the nutrition pot of electric hotbed, and excellent varieties with the characteristics of early maturity, high yield, small development degree, short internodes, suitable for intensive storage, early emergence of female flowers, dense fruiting, easy fruit setting, low temperature and weak light resistance, moisture resistance and strong disease resistance were selected.
2 greenhouse fruit and vegetable colonization
(1) Solanaceae. If tomatoes are planted early, they can be planted after spring begins.
(2) melons. After the spring, plant it in a small plastic arch shed or a large plastic shed, and cover it with a shed for cultivation.
3. Cultivation and management of vegetables in the open field
(1) Mainly do a good job in fertilizing peas, draining water after rain and setting seedlings. Mature vegetables should be harvested in time.
(2) Cruciferae vegetables (such as Chinese cabbage, green vegetables, radish, etc.) are planted in fields. ), to do a good job of topdressing and impurity removal in the field to ensure the purity and quality of seeds.
4 spring greenhouse melon and vegetable management
Spring greenhouse melons and vegetables refer to melons and vegetables harvested from March to early July. Most melon and vegetable varieties entered the vegetative growth period after beginning of spring, and the vegetative growth, flowering and fruiting of solanaceous vegetables were synchronous. Do the following cultivation and management:
(1) heat preservation and anti-freezing. There are two reasons for cold injury and freezing injury in early spring: First, plants grow vigorously, and the cold resistance of plants is obviously reduced with the increase of water and fertilizer under artificial management. There is still a big cold current after beginning of spring, which causes freezing injury and chilling injury of solanaceous vegetables in greenhouse. To this end, we must continue to do a good job in cold and antifreeze. Eggplant vegetables grow well and need to be covered with two layers of film in the greenhouse. Because melon is more susceptible to freezing than eggplant, straw bundles can be piled on the skirt film around the greenhouse to enhance the ability to resist the invasion of cold air around the greenhouse. Cucumber seedlings still in seedling stage can be covered with sunshade net, grass curtain or non-woven fabric on the small arch shed at night to enhance the heat preservation ability; In case of strong cold air, anti-freezing and heat preservation measures must be taken.
(2) ventilation. After beginning of spring, with the increase of sunshine time, the temperature rose and the humidity in the shed increased. In order to reduce the occurrence of pests and diseases and meet the requirements of the growth and development of melons and vegetables on environmental conditions, it is necessary to do a good job in the temperature and humidity management in the shed, and do a good job in opening the door, uncovering the film, ventilating, closing the door and covering the film for heat preservation according to the weather change and plant growth.
(3) Do a good job of flower protection and fruit protection. Low temperature will affect the fertilization results of many melon and vegetable varieties, and it is easy to drop flowers and fruits. At present, in production, the methods to improve the fruit setting rate are as follows: first, apply plant growth regulators in flowers or ovaries, and use them according to the instructions to prevent excessive concentration and phytotoxicity. The second is artificial pollination.
(4) Do a good job in pest control. With the increase of temperature and humidity in greenhouse, melons and vegetables in greenhouse are prone to gray mold, Fusarium wilt, Fusarium wilt and aphid damage. Pest control should be combined with agricultural control and chemical control, such as managing the temperature and humidity in the shed, reducing the humidity in the shed, spreading grass in the ditch, using water rationally, pruning in time, removing sick old leaves and spraying corresponding pesticides.
Third, fruit trees
1 citrus
(1) Young trees: do a good job in clearing the garden, maintain the irrigation and drainage system of the orchard, and accumulate citrus fertilizer. Finish shaping and pruning, the autumn shoots are too long and too short, and when the trees are too prosperous, the overlapping branches and dense branches are thinned out, and the short branches are too long; Small old trees were cut short before the spring buds sprouted. Apply heavy fertilizer, interplant green manure in the orchard, open holes and apply deeply, and loosen the soil and cultivate it on the tree tray at the same time.
⑵ Fruit trees: Prune and apply heavy fertilizer. Pruning: Pruning the weak trees with high yield in successive years, with the purpose of restoring tree vigor. When spring shoots sprout, cut off weak branches, diseased branches and dead branches, and cut off branches that have already borne fruit. Sparse clump-like "broom-like" branches, and weak branches with inner cavities "leaf piles" (2-3 inch branches with 2-3 buds) are short; Fertilization: expanding holes, improving soil, applying heavy fertilizer and digging ditches with a depth of 60 cm and a width of 40-50 cm. The length of the ditch depends on the tree crown. Apply soil miscellaneous fertilizer, 25-30 kg compost, 0.5- 1 kg phosphate fertilizer, 0.5 kg chaff fertilizer 1.5 kg lime. Spraying foliar fertilizer: 0.5% or 0.3% urea of compound fertilizer can cooperate with spraying for pest control.
2 loquat
Beginning of spring applied spring fertilizer in stages. For adult trees, in order to promote the growth of spring shoots and fruits, the amount of fertilization accounts for about 30% of the total amount of fertilization in the whole year. 20 kg of human excrement and urine is applied to each plant, and the ternary compound fertilizer is 0.8- 1 kg. Spraying 0. 1% borax solution at flowering stage in boron-deficient loquat orchard. For young trees, crown expansion is the main method, sparse and diligent application, and sparse human excrement and urine 10- 15 kg is applied to plants. In order to increase the weight of single fruit and strengthen the tree vigor, fruit thinning is generally carried out two or three times from mid-February to March after beginning of spring (the temperature is stable above 10 degrees). First of all, frozen fruits, abnormal fruits and diseases and insect pests should be removed, and then the fruit yield should be determined according to varieties and tree potential. Fruits should be selected and developed strongly and evenly distributed in the crown.
3 Myrica rubra
Do a good job of shaping and pruning. Pruning is mainly to improve the light in the crown, drain the upper and outer parts of Myrica rubra, and trim and update the lower or inner fruiting branches. Give priority to light cutting, and strive for ventilation and light transmission outside the crown. Old trees are mainly updated. Young trees are mainly shaped and cultivated into high-yield trees. At the same time, special attention should be paid to the development of the new garden. The seedlings should be deeply planted (submerged), watered in time after planting, and covered with weeds to facilitate survival.

What does beginning of spring eat for nourishing health?
Eat mild and fresh fruits and vegetables.
Beginning of spring season diet conditioning should consider the spring sun be the spirit is strong, sour taste into the liver, has a convergence effect. It is not conducive to the growth of Yang Qi and the release of liver qi. It is advisable to eat more fresh vegetables and fruits such as leek, jujube, peanut, onion, coriander, bamboo shoots and carrots and high-quality protein, such as milk, eggs, fish, shrimp, chickens and ducks, beef, etc., which can not only supplement calories, but also enhance the body's disease resistance. It is not advisable to eat more spicy, greasy and fried things. Patients with chronic liver disease can get twice the result with half the effort if they are given vigorous liver function treatment in spring.
Eat nutritious and protective food.
Spring is a clean season, and the body needs to be clean. The health care method after beginning of spring can be "drink more juice, eat more vegetables, clear the intestines, don't eat any sugar and caffeine for two weeks, and ban smoking." In addition, it is best to ban alcohol in spring, don't overeat, just be full at seven points, which will make your body more energetic.

Eat five spicy dishes.
Beginning of spring can also eat five spicy foods. The Spring Festival already existed in the Jin Dynasty, and it was called "Five Pan Xin" at that time. Five spices in a broad sense refer to five kinds of spicy dishes made of vegetables (onion, garlic, pepper, ginger and mustard). Taking five spices can sterilize and drive away cold.
Eat American ginseng
American ginseng has the effects of benefiting qi and nourishing yin, clearing away heat and purging fire, nourishing yin and promoting fluid production. American ginseng is recorded in materia medica: nourishing yin and benefiting qi, promoting fluid production to quench thirst, tonifying lung and reducing fire, calming nerves and relieving fatigue, which is suitable for people with deficiency fire. Therefore, American ginseng can effectively eliminate the phenomena of spring drowsiness and spring dryness.

What is the temperature in early spring?
After beginning of spring, the temperature in most parts of China rose above 0℃, the daily average temperature in Huanghuai Plain reached about 3℃, the average temperature in Jiangnan was about 5℃, the temperature in South China was above 10℃, and the average temperature in North China was still below 0℃. In China climatology, beginning of spring is usually defined as the day when the daily average temperature is stable above 10℃ every five days. China has a vast territory in low, middle and high latitudes. Low latitude generally refers to the spatial range between 30 degrees north and south latitude on the earth's surface, that is, the area between 30 degrees north latitude and 30 degrees south latitude, including tropical and subtropical hot spots, which is the area where global solar radiation and heat are concentrated. In low latitudes, it is rainy, stormy, sunny and humid. With the change of seasons, rainfall and storms also change obviously.
Mid-latitude is the latitude zone between 30 and 60 degrees north latitude. The air masses prevailing in high and low latitudes overlap each other in this area, and cyclone activities are frequent, and the temperature changes obviously when the seasons change. High latitude refers to the area between 60 degrees north and south latitude and the north and south poles on the earth's surface, which is the weakest area on the earth's surface to receive solar radiation. The climate varies greatly at different latitudes.
