Q: How should the autumn beans be planted?
A: Chen Chunxiu, Senior Agronomist
â– Site preparation
Choose loam rich in organic matter, deep soil, pH 7.0, good drainage, and frozen loam. Each 667 mus of compost organic fertilizer 3000kg, compound fertilizer 40kg, broken, leveling, for rake, surrounded by drains, groove width 80cm, depth 60cm. It is 40m long, north-south, and has a width of 1.3m (including 0.8m in width and 0.5m in width).
â– sowing
Use 50% carbendazim WP to seed 0.5% seed, or 40% polysulfide suspension 50 times to soak seeds for 2-3 hours, then rinse with clean water and sow.
â– Management
When throwing vines, the plants are combined with light pouring of manure water to promptly introduce the vines. A bamboo raft 2.5m-3.0m long was used to form a "human" shape. A crossbar was tied at the middle and upper part of the frame and fixed with a thicker frame every 15m to enhance its lodging resistance.
Fertilizer shelf beans have a long growing period and require more fertilizer. The principle is to apply sufficient basic fertilizer, lightly apply Miao Fei, apply it before flowering, and apply it in the logistic environment. In the early stage, the fertilizer should be controlled mainly; in the ranch stage, the feces water can be applied in combination with the cultivating soil, applying 1,000 kg per 667 mu, which will promote the growth of vine leaves and flower buds; the buds and flower buds will require a large amount of fertilizer every 667 mus. Ammonium sulfate 10kg or human fecal urine 1500kg; after flowering and scarring, less nitrogen fertilizer should be applied, 30kg of compound fertilizer per 667 square meters, superphosphate 10kg, potassium chloride 5kg. We will top-dress fertilizer once per harvest (5 days). Spraying a small amount of magnesium, iron, zinc and copper fertilizers can increase the yield and improve the quality. If the plants do not have premature aging and the climatic conditions are suitable for their fertility at the later stage of harvesting, fertilizers may be topdressed 1-2 times in order to promote flowering and extension. Harvest period, increase production.
Humidity management and weed control are suitable when the relative humidity at the flowering stage is above 50%, and the suitable soil moisture is 60%-70% of the maximum water holding capacity in the field. Drought or excessive rain can cause falling flowers. During the whole growth period, diseased plants and weeds should be removed in time, yellow leaves should be removed, light should be increased, and ventilation should be strengthened. Straighten out the purlins to prevent deformities caused by mechanical obstructions.
