Characteristics of soybean

Soybean is 30-90 cm high. Stems stout, erect, densely covered with brown bristles. Leaves usually 3-foliolate; Stipules and yellow pilose; Petiole 2-20 cm long; Leaflets broadly ovate, papery; Racemes have fewer short flowers and more long flowers;

The total pedicel usually has 5-8 sessile, closely arranged flowers; Bracts lanceolate, strigose; Bracteoles lanceolate, appressed setae; Calyx is lanceolate, with purple, lavender or white flowers, pedicels at the base and petal-shaped wings. Pods are plump, slightly curved, drooping and yellow-green;

Pods are plump, rectangular, slightly curved, drooping, yellow-green, 4-7.5 cm long, 8- 15 mm wide, densely covered with brown long hair; 2-5 seeds, oval, subglobose, ovoid to oblong, smooth seed coat, light green, yellow, brown and black. Flowering from June to July.

Storage method

1, strictly control the storage moisture, and the long-term storage moisture of soybeans shall not exceed 12%. After harvesting, soybeans should be fully dried on pods before threshing. After storage, soybeans with high moisture content can be exposed to the sun, but they must be spread and cooled before they can be put into storage.

2. Timely ventilation, heat dissipation and dampness elimination. The moisture content among the soybeans in the new warehouse is uneven. Coupled with the after-ripening effect of soybeans, the damp heat in the pile is easy to accumulate, causing fever and mildew, which requires timely ventilation, heat dissipation and dampness elimination.

3. After low-temperature sealed storage enters winter, ventilation should be strengthened to cool down. Before spring warming, sealed storage with gland or plastic film can generally pass the summer safely.
