First, timely sowing, nurturing strong seedlings. Seeding time selection In mid-April, in order to improve the quality and resistance of seedlings, nursery seedlings using early breeding. Seedbed selection in the sunny, easy drainage, deep soil, fertile, loose old block. After the winter sun white, 3-5 days before sowing the whole crop, fertilization, raking. Loose again before sowing noodles surface soil, watering clear surface soil 3.3 cm deep, you can sow. Mu sowing capacity of 50 kg. After sowing fine soil cover up to the degree of non-exposed, compacted cover film. Seedling management, mainly to keep moist noodles, to prevent high-temperature burning seedlings, noodles in the water when the film uncovering, leaflets started to expose the film hardening, 3 days before transplanting all uncovered, seedling age 25-30 days .
