The international market is in high demand. It is deeply welcomed by farmers because of its low input, high output, easy to plant and low risk. First, the variety characteristic growth period of 90 days, the need for active accumulated temperature of 2000-2200 degrees, seed coat black, white embryo, white flesh, 100-grain weight 19 grams, purple flowers, round leaves. The seed consumption per mu is 3 kg, 20-22 seedlings per square meter, the main stem begins to branch 4-5 cm from the root, and there are 4-6 branches. The general plant height is 35-45 cm, each plant has 30-60 pods, each pod has 6 seeds, the yield per mu is 150 kg, the high-yield plot can reach 250 kg, and there are basically no diseases and insect pests in the whole growth period. Second, the main points of cultivation have no strict requirements for the previous crop. Sloping plateau land, medium or lower fertility plots can be selected, and the total amount of chemical fertilizer N, P and K is 7.5 kg per mu or 10 kg of soybean special fertilizer.

Chemical weeding before seedling, using Guangmianling plus Acetochlor or weeds to burn. It is required to shovel three times in time. At the end of field management at the early flowering stage, leaf spraying micro-fertilizer mixed with potassium dihydrogen phosphate was carried out to promote early maturity, increase yield and improve quality. Third, when all the leaves of the whole crop are withered and yellow and there are 2 green leaves and 3 leaves falling off, they are pulled out by hand every morning and threshed by ordinary soybean thresher. Broken grains are strictly prohibited during threshing. Then dry it for 1-2 days and air dry naturally.
