High yield cultivation technology of black kidney beans

1. Variety characteristics: The growth period is 90 days, and the accumulated temperature must be 2000-2200 degrees. The seed coat is black, with white embryos and white sturgeons. It weighs 19 grams per 100 seeds, purple flowers, and round leaves. The planting amount per mu is 3 kg, and 20-22 seedlings are protected per square meter. The main stem begins to branch 4-5 cm away from the root, and 4-6 branches. The general plant height is 35-45 cm, 30-60 pods per plant, 6 seeds per pod, the average yield of the plot is 150 kg, and the high yield plot can reach 250 kg. There is basically no disease and pest in the whole growth period.

Second, the cultivation points have no strict requirements on the last crop. Select slope land, medium or low-grade fertile land can be applied, the total amount of fertilizer applied NPK fertilizer 7.5 kg or 10 kg of soybean fertilizer. Seeds can be seeded with soybean seed treatment agent, more than 35% of Fufu seed coating. Seeding depth 4 cm, seedlings on the top of the seedlings, 15 centimeters apart, 2 per seed. Pre-emergent chemical weed control, application of Guangfaling plus acetochlor or weed burning. Shovel trips are required in a timely manner, three times. The field management in the early flowering period was completely completed. At this time, leaf spray micro-fertilizer mixed with potassium dihydrogen phosphate was used to promote early maturity, increase yield, and improve quality.

3. Harvesting: When all the leaves of the crop are withered and 2/3 of the leaves fall off, they are manually pulled out every morning and threshed with an ordinary soybean thresher. Fragmentation is strictly prohibited during threshing. Then air dry for 1-2 days and air dry. Before entering the warehouse, incomplete empty particles are controlled at 1%, impurities 1%, and moisture 15%.
