[0014]Sowing period: When the daily average temperature is stable for 5 consecutive days above the biological starting point temperature of the seedling crops by 2-5°C, the seedlings can be sown.
[0015] Selected seeds: In order to improve the seedling rate, the seeds should be selected before sowing, and the large seeds should be selected by the grain selection method to select strong, plump and pest-free seeds, so that the germination rate of the seeds can reach more than 95%. The selected seeds are preferably sun-dried for 3 to 4 days in a row to promote post-ripening of the seeds and speed up the speed of germination and emergence.
[0016] Build nursery ponds or seedbeds filled with nutrient solution: the length of the seedbed filled with nutrient solution depends on the number of seedlings, generally 3-5m long and 50mm-200mm deep. Lay film (0.1mm thick) inside the bed to prevent water leakage.
[0017] Preparation of nutrient solution: Prepare a special nutrient soluti...
