Seed processing summer seedlings due to low emergence rate, the seed should be treated with low temperature. The method is to soak the seed for 12 hours, then wrap it in the refrigerator (2°C-5°C) for 2 days, and then spread it in the cool place until the seed cracks and germinates before planting.
Seeding and sowing should prevent uneven density. Before planting, water should be poured one time; 3 g -3.5 g per square meter should be planted; the shade net on the ground should be cooled, moistened, and then removed after emergence.
Seedling management Summer seedlings should be protected from rainstorms and high temperature and drought. Rainproof nursery and shade nets can be used to cover seedlings. The shade net is usually covered in the morning from 8 am to 4 pm on sunny days and it can be uncovered at night or on cloudy days. Dry weather should be watered in the morning and early evening. It can be top-dressed in combination with watering, and 0.3% potassium dihydrogen phosphate can be used for foliar dressing.
