When is the best time to plant soybeans?

It is more suitable to plant soybeans every spring.

Sowing soybeans in the open air in spring requires that the soil temperature must be above 65438 05℃ and the soil humidity is appropriate before soybean seeds can germinate. The ground temperature is too low to meet the requirements of soybean germination, so it can't germinate for a long time. Under the action of soil microorganisms, it will be moldy and rotten, which will make the seeds unable to germinate normally.

If it is necessary to sow in advance, plastic film can be used to raise ground temperature and promote seed germination. Generally speaking, the sowing time of spring soybean begins around Tomb-Sweeping Day. There is an agricultural proverb in rural areas, "Before and after Tomb-Sweeping Day, plant melons and beans", that is, sowing in early April to mid-April, the seed consumption per mu is about 10 kg, the whole growth period is100 ~10 days, and harvesting can be carried out in late July.

Matters needing attention in soybean planting

Planting density has a great influence on the growth, yield and quality of soybean. Different planting areas, different fertility, different topography and different soybean varieties will change the planting density we want to determine, that is to say, the planting density is not static.

Generally, it can plant 15000 ~ 20000 plants per mu in fertile soil, 20000 ~ 30000 plants per mu in medium fertile soil and 30000 ~ 40000 plants per mu in poor fertile soil. In fact, that is to say, the spacing between rows is generally 30 to 40 cm, and the spacing between plants is about 15 to 20 cm.
