Goal: To promote root growth, ensure seedlings, seedlings, and seedlings, and lay the foundation for high yields.
1. Check the seedlings to make up for deficiency: Immediately after emergence or transplanting, check seedlings and fill seedlings should be carried out. When filling seedlings, methods of transplanting with soil should be adopted. After rainy days or sunny afternoons, timely watering after planting should be conducted to shorten the time for seedlings to ensure survive;
2. Seedlings Dingmiao: generally 5-6 leaf period seedlings Dingmiao. According to the plan density requirements, remove sick, weak, miscellaneous seedlings and retain strong seedlings;
3. Cultivated weeding: can loosen the soil, raise the ground temperature and eliminate weeds, usually after the seedlings are set;
4. Fertilizers at the seedling stage: combined with cultivator weeding;
5. Excluding childbirth: (For fresh corn) Sweet waxy corn is more likely to produce tillers than normal corn, especially in the field where the planting density is low and the growth is prosperous. Most of the tillers grow out of the third and fourth leafhoppers and form lateral plants. They cannot grow into panicles, but grow vigorously. They compete with the main stem for nutrients and moisture, affect the ventilation and light transmission in the field, and should be removed in time before jointing. Nutrition concentrates on supplying the main stem. During operation, damage to the main stem should be avoided as much as possible.
