Non-pollution beans cultivation techniques
First, soil preparation and fertilization The soil with deep soil and rich soil, choose the soil that is rich in organic matter and has not been planted in the previous year, deepen 25cm before sowing, apply 5000kg of organic fertilizer per acre, 50kg of vegetable-specific compound fertilizer as base fertilizer, and then make a width of 1.2m. Hey. Second, sowing, nursery The bean seedlings were planted in open cultivation in late March, and the open field cultivation was broadcast in mid-April. The sowing rate per mu is about 2.5kg. Nursery generally use greenhouses, bean seedlings transplanting can be used small plastic bags or paper baskets nursery seedlings, planting 2-3 tablets per hole, irrigating the water, pay attention to insulation and control leggy. When the seedlings are raised, the seeds will be quickly scalded with hot water at 80°C-90°C. The cold water will be added to cool them quickly, and the water temperature will be maintained at about 25°C-30°C for 4 hours. The seedling age is generally 20-25 days. After emergence, keep the temperature at 20-25°C during the day. In the greenhouse, it is necessary to pay attention to heat preservation, ventilation, and ventilation to ensure that the seedlings grow neatly and robustly. Seed germination and seedling bed soil should not be too wet, so as not to reduce the germination rate, or lead to seedlings long, and even dead root rot. Third, colonization When the nutritional seedlings seedlings 2 to 3 compound leaves when planting. The open field cultivation can be planted in late April. Use a hole puncher to plant a hole and transplant it. After the planting, pour the rooting water and fill it with fine soil and seal the holes. In general, each row of beans is transplanted with two rows of beans, with a hole distance of 20cm and a 5000-5500 mound per acre. Fourth, field management Before transplanting to flowering, the bean pods were mainly controlled by water and cultivating roots, and appropriate seedlings were promoted to promote flowering and podging. After the pods were used, they were required to supply sufficient fertilizer and promote flowering and pod filling. After flowering and poding, the plants are usually top dressing 2 or 3 times, each urea 5 ~ 15kg or perishable human urine 750 ~ 1000kg, the harvest peak, with the water top dressing once, can be applied 25mu of diamine or two phosphate Hydrogen potassium 25kg. After the beans have been pumped, they should be racked in time and be raised 2.0 to 2.5 meters high. After the shelves are erected, the vines should be introduced in a timely manner. The vines must be taken in sunny afternoons. Do not carry them out on rainy days or in the morning to prevent them from breaking. Reasonable pruning, uniform distribution of stems and improve the utilization of light energy. Using main vines and side vine pods, increase the number of inflorescences and their scarring rate, extend the harvest period, and increase yield. For this reason, the side vines are properly selected, and the side vines that grow weakly and occur late in the first inflorescence are removed, and the vines are selected to grow vigorously, and the first vines that occur earlier in the first inflorescence are produced, and the side vines that grow above the middle of the main vine are extracted. 1 After the inflorescence, leave 4 to 5 leaves topping to increase the number of inflorescences and promote good inflorescence development. The main vine grows to the top of the scaffold and is topped when the vine grows to about 2m, promoting the formation of subfloral buds on each inflorescence. V. Pest Control The main diseases of beans are rust, downy mildew, anthracnose, leaf spot, etc., pests include aphids, spider mites, and soybean meal. Rust can be controlled by 20% triadimefon 1500-2000 dilution or 40% DuPont Fuxing 4000 times liquid or 50% Ganesha 600-800 alternate spray at the beginning of the disease; downy mildew can be 72% frost 600-800 Double liquid or metalaxyl Mn-Zn alternate spray control; aphids can be controlled by 1500-3000 times of Dekor, 10% imidacloprid 2000 times spray; red spider can be used 2% avermectin EC 6000 times spray control; Can be used 2.5% of deltamethrin 2000 times or cypermethrin alternate spray control.
