The main measures to control the falling of flowers and flowers in production are: selecting suitable varieties. High-yield, high-quality kidney bean varieties with strong adaptability and high yields should be selected. The second is to strengthen fertilizer and water management. The base fertilizer should be applied before sowing, and the plants should be planted in close proximity so that the plants have good ventilation and light transmission conditions. Seedling and flowering period are dominated by medium tillage, which promotes the healthy growth of roots. Into the end of the harvest, fertilizer and water management should be strengthened, and phosphorus and potassium fertilizers should be added. The third is the application of growth regulators. Spraying 5-25 ppm naphthalene acetic acid or 30 ppm tomato spirit during flowering can effectively prevent flowering and falling down. China Agricultural Network Editor
