When will soybeans be planted?

The planting time of soybean varies according to the weather, and it is generally divided into spring sowing and summer sowing:

Spring sowing is carried out before and after Tomb-Sweeping Day, and the harvest period is September (August of the lunar calendar);

Sow the wheat in summer after harvest, and harvest it from late September to mid-10. In addition, there is another kind of soybean in the northeast, which is sown later, but the harvest time has nothing to do with it.

In northern China, spring soybeans are sown from April to May, yellow summer soybeans are sown in June after wheat harvest, southern summer soybeans are generally sown from May to early June, and autumn soybeans are sown from late July to early August.

Pre-sowing treatment of soybean;

Soil preparation before sowing: Soil preparation before sowing includes soil ploughing, harrowing, ploughing and suppression. Different soil preparation techniques have different soil preparation before sowing, such as flat turning, ridge planting, harrowing and subsoiling.

Irrigation before sowing: For plots with poor soil moisture before sowing, if irrigation conditions are available, irrigation can be carried out 1 time 1 ~ 2 days before sowing, and the soil can be soaked after sowing to facilitate seed germination;

Closed weeding: if soybeans are planted in a large area and not managed in time, weeds will be seriously harmed. Before sowing, herbicide is often sprayed mechanically and closed weeding is carried out in the field;

Seed selection: the germination rate and germination potential of improved soybean varieties are high, and the seedlings are neat and strong. Before sowing, the diseased grains, moth-eaten grains, small grains, chaff grains and broken petals should be sorted out;

Seed treatment: the dosage of common soybean seeds is 0. 1 ~ 0. 15% octanol or 0.7% magic powder or 0.3 ~ 0.4% carbendazim plus thiram or 0.3 ~ 0.5% carbendazim plus captan.
