Every solar term guides farmers. What are the main agricultural activities in the 24 solar terms? In spring, farmers are gradually busy harrowing, fertilizing, sowing and planting wheat. Generally, spring tomatoes are cultivated in the open field in early February, and spring cantaloupes are sown in the first half of February. Sow green onions, and then sow spring potatoes in the middle and late February. In vegetable greenhouses, spring-ripe tomatoes and cucumbers are sown (both in early March), and three-film melons are planted in greenhouses (early and middle March). Wheat heading, you can see topdressing and heading fertilization, garlic, rape, wheat and pepper sowing and seedling raising.

Xia Xia should sow spring rice, spring black beans and grow onions. Harvest wheat seeds, rape and garlic. Harvest wheat. Forest crops are sprouting, weeding and fertilizing. In fact, it includes planting small miscellaneous crops, sowing spring crops such as soybeans and corn on a large scale, planting rice fields, and entering the busy farming. Sow summer onions and plant a pinch of onions. Sow summer lettuce and summer tomatoes in early and middle May. Harvest wheat seeds, rape and garlic. Planting large areas of wheat, rape stubble and garlic stubble refers to pepper, cotton wool and tobacco.

Autumn is a busy time for farmers. Crops such as peanuts, sweet potatoes, corn and rice can be harvested, winter wheat needs to be sown, and garlic should be dug out of the cellar before winter begins. This season, we should do a good job in crop cultivation techniques and sow late autumn crops such as black wheat. Cotton topping (must be completed) and trimming (topping) in early August.

Spraying mepiquat chloride to control vigorous growth and plant morphology. Control aphids, cotton bollworm (third generation, middle stage), red bollworm (second generation, early August), and tobacco budworm. There is a bumper harvest in autumn. Control soybean moth larvae (mid-September), tobacco field control tobacco budworm, cotton wool control red bollworm, and control summer rice borer (mid-September).

Sow semi-winter wheat (65438+1October in the first half of June) and weak spring wheat (65438+1October in the second half of June). Wheat seed dressing can control many diseases and insect pests, such as smut and smut. Spray ethyl acetate on cotton wool and cook it (about 65438+1October 5).

Harvest Chinese cabbage in time in winter to prevent snow from getting cold. Water wheat with packaged water, apply winter fertilizer and topdressing, and kill budding insects and Laodelphax striatellus with pesticides. Avoid wheat sheath blight. It is best to use some herbicides properly. In addition, winter broccoli will be planted in the first half of June, 165438+ 10. 165438+1In the first half of October, winter lettuce was planted. In the first half of June, 1 1, spring cabbage was planted in the open field. Autumn cauliflower can harvest 5438+065438+ 10 in the first half of June. 65438+1in the middle of October, spring pepper was planted in the open field to raise seedlings. 65438+1In late October, cantaloupe in small arch shed was sown to raise seedlings.

Classification of farming activities The first thing to be done in farming activities is sowing. The sowing time of grain crops is different. Rice, cotton wool, corn and sorghum are gradually sown in spring all the year round, and seeds are selected in the spring sowing season. Before the farmland, spread the fertilizer evenly, carefully plough, and sow the seeds on the farmland in good weather.

When seeds and seedlings gradually take root and sprout in the soil, they will gradually carry out crop management methods, including water injection, fertilization, pest control, weeding and other thematic activities. And water and fertilize properly according to the growth status of plants and meteorological factors, such as irrigation in summer when the temperature is high and the drought is serious, and spraying pesticides properly when the pests are serious.

When the crops grow well, they need to be harvested step by step immediately. Different grain crops are harvested in different ways. For example, common rice harvests ears by harvesting seeds. It is said that autumn is the harvest season, and cotton, corn, soybeans, peanuts and taro must be picked. After harvesting, we should pay attention to the greening of crops.
