Specific requirements: seedbed membrane net double cover, the first cover film with compressed film and then cover the shade net; seedling mu with lime powder 50 kg, 48% of compound fertilizer 20 kg, superphosphate 40 kg, plowing soil Settlement for the car, required to reach the flat as a mirror, soil fine as powder, ditch phase line, ditch width 40cm, ditch depth 20-25cm; acres with herbicide 100 grams, water 30 kg spray, before sowing Weeding; 4 bags of green hens, sprayed evenly with a watering can. Pouring enough water to ensure that the seeds germinate the required moisture.

After the first day of sowing, the seedbeds were covered with ultramicro-membrane or plastic film, and then covered with straw evenly on the mulch, and appropriate amount of fresh water was sprayed to ensure soil moisture and reduce temperature. Strict seedbed temperature and humidity management, when the temperature is higher than 35 °C, pay attention to lifting the high film, pay attention to put down the film when the storm, the soil can be sprayed on the straw when the amount of dry water. 3 to 5 days after sowing, seedlings unearthed more than 50%, you can uncover the film.

Use 0.3% potassium dihydrogen phosphate and 100 times liquid dimethoate for foliar sprays to treat aphids. With 5% stuck 200-fold or 5% Suppository 200-fold or Bt emulsion 500-fold seedbed spray, pest control, 15 days interval. When the seedlings 6-7 true leaves can be planted. In the 10 days before planting, the practice of hardening seedlings is to reduce the number of watering. The second is to gradually reduce the sunshade net cover time, increase light, and cultivate strong seedlings. Colonization should be done after 5 pm on cloudy or sunny days.
