What solar terms are most suitable for soybean planting in Huaibei area?

It is most suitable to plant soybeans in summer solstice solar terms in Huaibei area.

Wheat in Huaibei is harvested in late May and early June, and then soybeans are planted. Sow soybeans immediately after wheat harvest, and sow soybeans in the field before June 20 at the latest. In some places, farmers unilaterally think that it is not good to plant soybeans early. Even if the soil moisture is sufficient after wheat harvest, they will not sow, but postpone sowing until late June or even early July.

In fact, the key factors affecting soybean are the rainfall and the number of days of rainfall during flowering and pod setting, which is a natural phenomenon that is not transferred by human subjective will. Delaying sowing not only shortens the growth period, but also has a great chance of encountering unfavorable natural factors. Therefore, the effect of soybean early sowing is better than that of late sowing. The suitable water content of topsoil for sowing and emergence is 18% ~ 20%, and the soil moisture should be grasped in time after wheat harvest. If the weather is dry and there is no rain in the near future, it is necessary to fight drought and sow soybeans in time.
