Every 667 square meters (m2) of high-quality farmyard fertilizer 5000kg (kg), which spread 4000kg (kg), deep-dump 30cm (cm), after the leveling ditch application farmyard fertilizer 1000kg (kg), per 667 square meters (Square) Application of three elements of compound fertilizer 30kg (kg), furrow irrigation from the greenhouse 50cm (cm) small ridge, Dianxiang greenhouse from 100cm (cm) ridge. 1.3 Seeding in late July sowing seedlings, row spacing 30cmX50cm (centimeters), ridge row spacing 30cm-40cm-100cm (cm) o 30cm (cm) spacing on the ridge planing, every 667 square meters ( Square meters) apply three elements of compound fertilizer 15kg (kg), drench water, seepage after sowing each 3-4 seeds, cover soil 4cm-5cm (cm). 1.4 Seedlings, spade shovels, film seedlings 2 true leaves time seedlings. 2-3 strains of seedlings were left, scooped again, and the ridges were repaired and covered with mulch. After the seedlings are released, soil shall be used to tightly seal the seedling hole. The ventilation and heat insulation shall be increased in July and August to increase ventilation. The ventilation shall be reduced in September, and the ventilation shall be stopped in October. Cover quilts in mid-September for cold insulation. 1.6 Water and Fertilizer Pre-stage Control Irrigation to prevent unpleasantness. In the initial stage of scarring, combined with irrigation of 667 square meters (m2), topdressing potassium sulfate 10 kg (kg), and during the peak period of 10 days (days), water is poured once, and 2 water is separated by 667 square meters ( Square meters) top-down compound fertilizer 15kg (kg), reduce the irrigation later.
