Kidney bean seeding and seedling cultivation: selection of good varieties of kidney beans: such as May Fresh, Red-billed Swift, and 28-2 in the month, August, Pan-xiang, Jiangsu Maohong and Zhejiang 512 varieties.
Timely sowing: live or nursery transplant period is from late April to mid-July, from late June to early November.
Reasonable and dense planting: The 28-2 plant uses 1.3-1.4 meters wide planting (even ditch), planting two rows, the hole distance is 20-23 centimeters, three plants per hole, maintains 140000-16000 plants per acre, late-maturing varieties such as August, etc. There are many vine leaves, strong branching, and it is not appropriate to plant too dense. It should increase the distance from the hole to 30-33 cm, 2 per hole, and 7000-8000 seedlings. When vines are drawn, they should be erected in a timely manner so that the stems spread evenly on the racks. The type of scaffolding mainly uses herringbone.
Fertilizer management: The amount of fertilizers at the seedling stage is not large, about 3 to 5 kilograms of urea per acre, and 6 to 10 kilograms of nitrogen fertilizer per acre after flowering and scabbing, 1 to 4 kg of phosphate fertilizer, and 2 to 4 kg of potash fertilizer, divided into 2 to 3 times With watering. Harvesting spraying 1% to 2% of potassium dihydrogen phosphate every 5 days is beneficial to the harvesting. After 25 to 30 days of harvesting, a quick-release organic fertilizer or N, P, K compound fertilizer (30 to 50 per mu) is reapplied. kg). Can be applied at the edge of the trench or directly sprinkled on the surface. Watering should be controlled to prevent leggy before flowering and scabbing. Non-mulch cultivation requires cultivating loose soil and grass. If there is no rain after flowering, it takes about 5 days to water once to keep the soil moist.
Pest control: Strengthen the prevention and treatment of aphids, bean pods, cowpea mycoticosis and cowpea rust.
Dwarf bean composting: After deep soil preparation, 30-50 kg of phosphate fertilizer, 10 kg of compound fertilizer and 15 kg of potassium fertilizer are applied per acre. After fully mixing, the sorghum is made into a sorghum with a width of 1.8-2.0 m (gap ditch). 20-25 cm, 30 cm deep.
Sowing: Autumn sowing takes place from mid-July to early August. Dwarf bean varieties were selected and sown in the sun for a day or two. Harvesting can begin about 60 days after sowing. Plant spacing is 30 to 35 cm, with 1-2 seeds per litter and about 2 kg per mu. When planting, the soil should not be too deep. After sowing, the soil can be watered once or not with water.
Fertilizer management: the kidney bean is usually watered with 10% feces or 3-5 kilograms of urea after the second pair of true leaves are grown; when the plants start to grow, the ternary compound fertilizer is used to soak the water. After topdressing, the amount of fertilizer per acre is 6-9 kg and the application amount of nitrogen fertilizer is controlled. When the flowering begins, the compound fertilizer is applied twice, each 12-15 kg.
Flowering management: Before the flowering, use 1500 times liquid of farmer flowering essence or 5-25 mg/liter of gibberellin liquid to do foliar and stem spraying to promote flowering and increase scab; flowering period uses 5-25 mg/L. The B-Naphthalene Acetate Spray or 0.3% Potassium Dihydrogen Phosphate Foliar spray has a certain effect on the prevention of falling flowers.
Harvest: timely harvest, under normal circumstances 10-15 days after flowering can be harvested.
