Latest summary of soybean's requirements for environmental conditions
Soybean is one of the main food crops in China, its planting area is very wide, and soybean has high nutritional value and large market demand, so its planting prospects are still quite good. However, it cannot be planted just anywhere, because growing soybean requires an environment suitable for soybean growth, otherwise soybean will be difficult to survive. So what exactly are soybean's requirements for environmental conditions? Below, the editor brings you these environmental requirements, let's take a look!
1. Soil
Soybean has relatively strong adaptability and does not have great requirements for soil; most soils can support normal growth. However, to grow high-quality, high-yield soybean, it is still necessary to choose soil with normal drainage and irrigation, rich humus, strong water and fertilizer retention, and that is deep and soft. The soil pH value should be maintained at around 6.5-7, and an appropriate amount of fertilizer should be applied to the soil to improve soil fertility. After planting, do a good job of topdressing to ensure that soybean growth has sufficient nutrients, and prevent insufficient soil fertility from affecting soybean growth and reducing yield.
2. Temperature
Soybean relatively prefers to grow in a warm environment. Moderate temperature is beneficial to soybean growth. After growth begins, the temperature must not be lower than 6 degrees for the seeds to gradually sprout. Around 11 degrees is the most suitable germination temperature for the seeds. The cold resistance of soybean seedlings is related to their growth conditions; usually the temperature must not be lower than zero degrees. During the soybean growth period, the temperature should be controlled at around 20 degrees. If it is lower than 15 degrees, flower bud differentiation will be greatly hindered, reducing the pollination and seed-setting rate. In the later stage, the temperature also must not be lower than 12 degrees, otherwise grain filling will be affected to a certain extent.

Because soybean pods are mainly distributed on the upper and lower parts of the plant, the entire plant must be ensured sufficient light to promote leaf photosynthesis and increase nutrient accumulation. Therefore, during the planting process, the permeability of the plant should be improved to ensure that the plant leaves can receive sunlight comprehensively and evenly. However, soybean is also a short-day crop, so the daily light duration should be well controlled, and the ratio of darkness to light time should be well controlled to promote soybean flowering; otherwise, the soybean growth period will be prolonged.
4. Water
Soybean has relatively large water demand throughout the entire growth period and is among the top food crops in terms of water consumption. However, soybean has different water requirements at different growth stages. During the period from sowing to before emergence, ensure the soil is thoroughly wet to enhance seed water absorption and promote seed germination and emergence. The soil moisture content should be maintained at around 55%. Then, by the flowering stage, soybean growth speeds up and water demand also rises sharply. However, too much watering should be avoided to prevent root rot and flower rot, so when watering too much or encountering cloudy and rainy days, drainage should be carried out in time.
The above is a brief introduction to soybean's requirements for environmental conditions. Although soybean can grow healthily on most soils, the yield will definitely decline somewhat. Therefore, we still cannot choose soil casually, to avoid insufficient yield and affecting the economic benefits of planting. That is all for today's introduction. This article is for reference only.
