Learn soybean planting and management techniques well, high yield and high benefit is not a problem!

Soybean, commonly known as soybean, is widely planted in various parts of our country. As one of the widely planted food crops, planting management technology is the key factor of high yield and high benefit. Please remember what is going to be introduced below.

I. related situation of soybeans

1. Price of soybeans

At present, the price of soybean car plate in Mudanjiang bean merchant is 3620 yuan / ton, the domestic purchase price of soybean gross grain is 3380 yuan / ton, the purchase price of edible soybean net grain in Muling City is 3400 yuan / ton, and the purchase price of Boli County edible soybean net grain is 3400 yuan / ton.

two。 Soybean yield per mu

Under normal circumstances, the yield per mu of soybean is between 400kg and 600jin. At present, the highest yield per mu in China is 811kg in Xinjiang and the highest in the world is 1388 jin in the United States.

3. Soybean subsidy

In 2018, the subsidy standard for corn producers in Heilongjiang Province is 25 yuan per mu, and the subsidy standard for soybean producers is 320 yuan per mu. China's soybean planting subsidy policy may continue to increase in 2019.

II. Soybean planting management technology

Soybean planting in order to achieve high yield and high efficiency, planting management technology is very critical, let's learn about it.

1. Soybean pre-planting preparation

Soybean planting should choose the soil with flat terrain, deep soil and high fertility, shallow turning, deep loosening and soil preparation in autumn, ridge cultivation should be well ridged, flat cropping plots should be leveled and raked fine, so as to reach the state of waiting for sowing; the whole land should apply base fertilizer, including organic fertilizer, phosphate fertilizer and part of nitrogen fertilizer, and some potash fertilizer can be applied in potash land.

two。 Sowing technology of soybean

There are many varieties of soybeans, which can be selected according to local conditions, and should be carefully selected and treated before sowing. Sowing soybean seeds in summer can be carried out after the local temperature of 7-9 degrees Celsius. Generally speaking, the planting density of soybeans is 40-450000 plants per hectare before autumn sowing in mid-August.

3. Field management of soybean

When the first compound leaf of soybean was unfolded, the plant height of 25-30 cm was deeply loosened for the second time; in general, 25-35 kg of nitrogen fertilizer, 150-225 kg of diammonium phosphate and 50-75 kg of potash fertilizer were used in ridge three cultivation of medium fertility plots. When close planting is adopted, the amount of fertilizer application is increased by 10-15%. At the early flowering stage, soybeans were sprayed with 1.5 kg of potassium dihydrogen phosphate per hectare, dissolved in 200 kg of water.

4. Pest control and weeding management of soybean

Weeding and loosening the topsoil before the first compound leaf of soybean, the seedling height of 10 cm was ploughed for the second time, and the third deep ploughing was carried out ten days later. If herbicides are applied to weed control, special attention should be paid to the drug damage to the following crops.

During the planting period, attention should be paid to heart-eating insects, aphids, red spiders, gray leaf spot and stem break disease, and it is best to prevent and control them in advance. Different pesticides should be applied according to different conditions, and the dosage should be determined according to the situation.

In fact, it is not difficult to grow soybeans, and if you master the planting management technology, you will not be afraid. When planting, we should choose varieties with strong disease resistance and high yield, and at the same time pay attention to the changes in the market.
