1. The sowing density should not be too large, so as not to crowd the seedlings after emergence. At the same time, about 30% of the seedlings were removed from the ground cover in time.
2. Time seedlings and planting.
3. Strengthen ventilation and light transmission, and control temperature and humidity. After the seedlings are unearthed and before planting, ventilation and light transmission should be carried out, the temperature and humidity should be reduced, and the low temperature exercise should be strengthened to control the excessive growth of the seedlings.
4. Reasonable fertilizer and water management. In the preparation of nutrient soil, we should pay attention to the amount of phosphorus and potassium fertilizer, and control the amount of nitrogen fertilizer. The water and top dressing in the seedbed are strictly controlled, and nitrogen fertilizer can not be applied when top dressing is required.
5. And time seedlings. About 20 days before planting, the seedlings are often overcrowded, and the seedlings should be moved appropriately to separate the large and small seedlings and expand the living space of a single plant.
6. Use chemicals to control the growth. Once the seedlings grow, in addition to taking the above measures, 50% chlormequat can also be sprayed with 2000~2500 times.
