Soybean is a plant of Leguminosae and Soybean, with a height of 30-90 cm. It is one of the important food crops in China. It has been cultivated for 5000 years. It is mainly produced in the northeast of China. It contains a lot of protein, which is most commonly used to make various bean products, and can also be used to extract soybean oil and brew soy sauce.

Soybean is generally called soybean, which can be divided into soybean, green beans, black beans, feed beans and other soybeans.

Soybean planting conditions

Soybean is a thermophilic crop, but it also has strong cold tolerance, needs more water and is relatively waterlogged-resistant, and needs to provide enough water to maintain soil moisture during its growth.

Climate and temperature of soybean planting

The optimum temperature for soybean flowering and pod setting is 20 ~ 28℃. The pod setting is delayed at low temperature, and it can't bloom below 14℃. The high-temperature plants end their growth ahead of schedule, which is suitable for planting in temperate regions with high temperature in summer.

Suitable for soybean planting area

Soybean has strong adaptability to the environment, and requires little soil, so most soil can grow normally. However, in order to improve the quality and yield of soybean, it is still necessary to choose deep soft soil with normal irrigation and drainage, rich humus, strong water and fertility conservation and pH value around 6.5-7. Some base fertilizers can be applied to the soil to improve soil fertility.

The northern spring soybean area should be divided into three subregions, the Huanghuaixia soybean area should be divided into two subregions, and the Yangtze River spring and summer soybean area should be divided into two subregions.

Soybean planting time

Soybean is suitable for sowing in summer and autumn. Summer sowing soybeans can be sown when the soil is suitable after wheat harvest. The best sowing date is June, not later than the beginning of July, and autumn sowing is usually in August, and the sowing amount is 8- 10 kg per mu.

Soybean planting benefit

Experts say that the value range of soybeans will move towards 800- 1500 cents in the next few decades. They said that the history of soybeans worth $ 5-8 in the past few decades will become a thing of the past. So far, the three historical highs of soybean futures prices are lower than one, and the number of soybean futures prices standing in high-priced areas is getting less and less.
