Planting techniques of soybean

Soybean plays a very important role in China, and it is one of the staple grains in our country. The consumption of soybean in China is very large every year, and its market demand is increasing year by year. And China is also a major exporter of soybeans. Therefore, with the increase of market demand, the planting area of soybean urgently needs to be expanded. So how to grow soybeans? The following editor brings you the planting technology of soybeans, let's have a look!

1. Land selection and preparation

Soybean is suitable to grow on the land with fertile soil, normal drainage and irrigation and no diseases and insect pests, which can effectively increase the yield of soybean. However, we should pay attention to the non-continuous cropping of soybean, otherwise it is very easy to produce diseases and insect pests and affect the growth of soybean. After selecting the site, turn the soil about 30 centimeters deep, and then flatten it. Pick out the previous crop residues, weeds and large stones in the field to avoid the existence of bacteria to harm the growth of soybean. Then according to their own planting habits to decide whether to ridge cultivation or border cultivation.

2. Variety selection

There are many varieties of soybeans, so we should choose the suitable varieties according to the actual situation of the soil, environment and other factors. After buying seeds, we should pay attention to the work of accelerating germination and disinfection of seeds. First, soak the seeds in warm water of about 40 degrees for about 5-6 hours. When it is found that the seeds are bloated, fish them out and dry them to break the dormancy period of the seeds. Then the seeds were mixed with chemicals to avoid being harmed by underground pests, eliminate the internal germs of the seeds and improve the germination rate.

3. Sowing seeds at the right time

The sowing method of soybean should be adjusted according to different varieties when sowing. For example, strip sowing is dominant for early-maturing varieties and hole sowing is dominant for late-maturing varieties. Then choose the appropriate sowing time according to the season, if it is summer sowing, then it should be carried out after the wheat harvest. Do not sow too late, no later than July at the latest, otherwise it will have a certain impact on soybean yield. When sowing, we should pay attention to control the sowing density, not too dense, so as to prevent the growth of mutual influence. After sowing, cover the soil with plastic film and water properly to improve the germination rate of seeds.

4. Daily management

When planting soybeans, we should pay attention to a series of management work, such as water and fertilizer, ploughing, weeding, shading and so on. First of all, it is necessary to control the moisture to meet the growth moisture of soybean, at the same time, it should not be excessive to prevent retting roots from causing diseases and insect pests. According to the soil fertility and the growth of soybean and other reasonable topdressing. When the field temperature is too high, we should pay attention to do a good job of cooling to avoid direct sunlight on soybean plants, resulting in soybean burns. Then regular ploughing and weeding should be carried out to prevent weeds from separating nutrients, reasonably improve soil structure, improve soil fertility, and promote nutrient water absorption of soybean.

The above is a brief introduction to soybean planting technology. When planting soybeans, field management is very important. Therefore, we must strengthen management, improve the growth capacity of soybeans, increase yield, and protect their own planting benefits. That's all for today's introduction.
