Soybean is a plant of Leguminosae and Soybean, with a height of 30-90cm. It is one of the important food crops in China with a cultivation history of 5000 years. Known as Zizania latifolia in ancient times, the main producing area is in the northeast of China. It contains a large amount of protein, which is most commonly used for making various bean products, or extracting soybean oil and brewing 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 warm crop, but it also has strong cold tolerance, needs more water and is relatively waterlogged-resistant, and needs to provide enough water to keep the soil moist during its growth.

Climate and temperature of soybean planting

The optimum temperature for soybean flowering and pod setting is 20 ~ 28℃. Pod setting was delayed at low temperature, but it could not bloom below 14. High-temperature plants end their growth ahead of schedule and are suitable for planting in temperate regions with high temperature in summer.

Suitable for soybean planting area

Soybean has strong adaptability to the environment, and has little requirement for soil, and most soil can grow normally. However, in order to improve the quality and yield of soybean, soil with normal irrigation and drainage, rich humus, strong water and fertilizer conservation and deep and soft soil layer should be selected. When the pH value is about 6.5-7, some base fertilizers can be applied to the soil to improve soil fertility. The northern spring soybean region should be divided into three sub-regions, the Huanghuai summer soybean region should be divided into two sub-regions, and the Yangtze River spring sowing summer soybean region should be divided into two sub-regions.

Soybean planting time

Soybean is suitable for sowing in summer and autumn. After wheat harvest, the soil is suitable for planting summer soybeans. The best sowing date is June, not later than the beginning of July. Autumn is usually sown in August, and the sowing amount per mu is 8- 10kg. Experts say that the price of soybean will rise to 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. At this point, the three historical highs of soybean futures prices are getting lower and lower, and the number of soybean futures prices standing in the high-priced range is getting less and less.
