Breeding cultivar Laiwu mainly has two types of creeping and dwarf, vines variety: Tianma 95 ~ 33 beans king, oil beans; dwarf varieties: Pecan beans, French beans, local peanut beans. Second, the election The choice of flat terrain, drainage and irrigation is convenient, sandy soil and light clay are suitable for deep soil cultivation and high fertility. Third, fertilization site preparation Apply enough base fertilizer before planting, apply 2,000 to 3,000 kilograms of farmyard manure per acre, 50 kilograms of ternary compound fertilizer, and spread the fertilizer evenly, deepen 30 centimeters deep, and grind the leveling material. 200 centimeters wide, 170 centimeters wide and 30 centimeters wide. Fourth, reasonable dense planting Choose shiny, full-grown seeds, soak for 1 day before sowing, 4 to 5 rows per seedling, spread 100 cm to open, 30 cm wide, 20 cm deep, 2 rows per mu, per mu 2500 to 3500 ponds, sowing 4 to 4 seeds per pond; dwarf beans 200 cm open, 4000 to 5000 ponds per acre, after sowing water to cover the film. V. Field Management (a) pre-management. Bean sowing to seedlings to maintain moist noodles, no compaction, seedlings grow to 3? 4 pieces of real leaves broken film and Dingmiao, combined with watering 15 kg of urea per acre, to promote the growth of stems and leaves, while climbing beans should be timely scaffolding. (b) Flowering and fruiting period management. Close to the flowering should be controlled watering, after the scab began to water, keep the soil moist, when the tender oysters lived, pouring attacking drowning, combined with fertilization, urea 15-20 kg per mu. Every harvested 2-3 times, chase 1 fertilization, Mushi Sanyuan compound fertilizer 15 kilograms, watering immediately after each top dressing. In the middle and late stages of planting, plants enter the ageing period, and diseased, old and dead leaves should be removed in time to improve the ventilation and light transmission conditions. VI. Pest Control (1) Powdery mildew and rust: Control with 15% triadimefon 500 times, 75% chlorothalonil 600 times. (b) root rot, angular spot: 72% sulfuric acid with streptomycin 3000 times, with 77% can kill 500 times liquid control. (3) Locusts, leaf miners, and locusts: 20% killing and 4000-fold killing, 48% Lesotho-emulsion 1000-fold control, and 2.5% kung-fu 4000-fold control of soybean meal. 7. Harvesting Harvesting occurs when the fruit is fully grown but still young, and can be harvested once every 2-3 days during the harvest season.
