In order to ensure healthy seedling establishment, it is essential to sow seeds as soon as the soil conditions are suitable. Timely sowing helps maximize germination rates and promotes uniform growth. Before planting, seeds should be air-dried to reduce moisture content and enhance their viability. Applying seed coating agents or dressings can significantly improve seed vigor and protect against diseases. Suitable options include zincphosphate, 25% triadimefon, or 34% Weifu seed dressing, which help boost seed performance and resistance.
Regarding fertilization, it's recommended to apply phosphorus and potassium at the end of the growing season. If nitrogen fertilizer is used over a long period, it can be applied in one dose at the end. For common fertilizers like urea or ammonium bicarbonate, about 60% of the total should be applied as base fertilizer, while the remaining 40% can be used as a top-dressing later.
After sowing, regularly check the seed coverings to ensure they remain intact. If any areas are exposed or damaged, cover them promptly with soil to maintain proper moisture and temperature for germination.
For weed control, herbicides such as atrazine are effective, and can be combined with other suitable products like lanso or acetochlor for better results. It’s important to spray the herbicides immediately after application, using enough water to ensure the solution penetrates the soil surface and becomes active within three hours.
In terms of disease and pest management, common issues like smut can be controlled using 10% triadimefon wettable powder or 12.5% diniconazole wettable powder. For corn borer infestations, 3% phoxim granules or 30% acephate emulsifiable concentrate are effective. Regular monitoring and timely treatment are key to preventing major losses and ensuring a healthy crop.
