First, sowing should be sowed early, early rainfall, prone to root rot, pests and more, are unfavorable to faba bean flowering and scarring, if too late, affected by the late low-temperature drought, fruit dysplasia, low yield . During the period from the beginning of autumn to the summer heat, the light, warmth, and rain are more suitable for the growth of autumn broad beans, which is the best time for sowing. This can be achieved before and after listing in the winter. 2. Appropriate density broadcast to ensure that the seedlings are properly increased in sowing density, and 12-12.5 kg seed per acre is appropriate. Seedlings should also be seeded in time to ensure the seedlings. Third, fertilizer and water management Autumn broad bean vegetative growth period is short, sowing about 25 days to flower, must be enough base fertilizer, scientific fertilizer. Basal fertilizer is generally 1000-1500 kg of mature livestock and poultry, 20 kg of phosphate fertilizer, covered with fire and earth ash. Top dressing should be timely and appropriate, when the seedlings grow 3-4 leaves, combined with cultivator, with 100 grams of urea plus 20 kilograms of water or use of abattoir urine. When faba bean bloomed, compound fertilizer was applied every 10 days or so. Decomposition of human urine or ash, combined with topping when fertilizing. In addition, fertilizers should be applied outside the roots in a timely manner. You can spray 0.2% of molybdenum fertilizer or 0.2% of potassium dihydrogen phosphate to reduce the fall of flowers. Seedlings sunny days should be pouring water, rain should pay attention to drainage, to keep the sulcus is not water; flowering water management to slightly dry as well, can inhibit vegetative growth, promote reproductive growth, thereby increasing production. Fourth, pest control disease seedlings often occur locust damage, and timely application of pesticide control, can be used 40% dimethoate or omethoate 100 grams of water plus 50 kg spray. In the middle period, horses and locusts are harmed and can be sprayed with 40% of dimethoate and 75 grams of water and 60 kg of water. Root rot can be used to lyse roots with 500 times the enemy's liquid, and can be used to spray 70% of thiophanate-methyl 1000 times.
