What agricultural activities are there at the beginning of spring? Beginning of spring is the first of the 24 solar terms, and the climate at this time is very suitable for agricultural activities. So, what kind of agricultural activities does it have? Here are some farm activities at the beginning of spring.

What farming activities are there in the spring? 1 What farming activities are there in the spring?

Agricultural activities in spring 1. 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.

Agricultural activities in the spring season. vegetables

1, seedling raising of melons and vegetables in greenhouse in spring

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. grow fruits and vegetables in the greenhouse

(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. Greenhouse melon and vegetable management in spring

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 diseases and insect pests 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 doors, uncovering films, ventilating, closing doors and covering films 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.

Agricultural activities in early spring. fruit tree

1, citrus

(1) Young trees: do a good job in clearing the garden and maintain the irrigation and drainage system of the orchard.

Citrus fertilizer and other work. 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.

The upper part and periphery of Myrica rubra became thinner, and the lower part or inner cavity of the branch group became shorter and newer. 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 farming activities are there in the spring? Beginning of spring is the first of the 24 solar terms in the lunar calendar, and it is also the first day of spring, which indicates the beginning of a year's farming activities and has always been valued by the Han people. As early as the Song Dynasty, beginning of spring's customs were already very rich.

First, whip spring. On the day when spring begins, people make and whip cows to persuade farmers to farm. According to "Tokyo Dream Record", the day before beginning of spring, Kaifengfu entered the palace with spring cattle, and the Emperor sent people whip Spring, and Kaifeng and Xiangfu counties also sent the spring cattle to the front of Kaifengfu to whip the spring. As a rule, other state capitals should also urge farmers on the day of spring. After the whip spring, onlookers often scramble to grab the clods. Because it is said that cows should be buried in the house, silkworms should be raised at home and land should be cultivated at home, the robbery is fierce and sometimes even fatal. In addition, the clay sculpture of Koharu cows in early spring is still a popular holiday gift.

Second, cut the spring to win. In the Eastern Han Dynasty, beginning of spring had the custom of cutting spring banners. In the Song Dynasty, it was like a high-grade ornament of "carving gold ornaments, adding pearls and jade, or using gold and silver, which was very clever". On the day when spring begins, the emperor will also reward officials for their victory in spring. "The color wins a hundred crowns and flutters" reflects the scene of officials leaving the palace and singing praises.

Third, drink spring wine and eat spring vegetables. Spring plate is spring cake. Eating spring vegetables began in the Tang Dynasty. On the day before the spring, the emperor would send his courtiers spring dishes and spring wine, and the folks also had the custom of giving each other spring dishes.

Fourth, write poems about spring. Beginning of spring of the Imperial Academy will write spring poems the month before, and beginning of spring will cut and paste them in the palace account, which is called "Spring Post". Most of them are palace poems or landscape poems.

In addition, on this day in beginning of spring, people in Shi Jing cut chicken swallows, flowers and willows out of silk, and tied feathers on the chicken swallows, calling them Spring Chicken, Chun Yan, Spring Flower and Spring Willow.
