Jinda 74 (soybean)
Jinda 74, a new soybean variety newly bred by Professor Li Guiquan, a soybean expert of Shanxi Agricultural University, has become one of the three new soybean varieties newly approved by the Crop Variety Approval Committee of Shanxi Province this year because of its strong drought resistance, good yield, high resistance to mosaic virus and great yield potential.
Jinda 74 was bred by crossing Jinda 52 and Jinda 47. It is a variety of spring and summer sowing, especially suitable for planting in high fertility and sufficient water. Experts said that under the conditions of improved varieties, good methods and good land, the yield can reach about 400 kg, which is another super-high-yield new variety in Shanxi Province.

Beware of falling flowers and pods of soybean
The drop of flowers and pods of soybean is the main factor affecting the increase of soybean yield. in production, the rate of flowers and pods of soybean is generally about 45% and 70%. The most flowers fell at 5 days after flowering and pods fell at 15 days at 10 days after flowering. In order to increase the yield of soybeans, great efforts must be made to prevent flowers and pods from falling. 1. The reasons for falling flowers and pods 1. Poor ventilation and light transmission due to excessive planting density and poor planting technology, resulting in overgrowth and overgrowth.
