In pursuit of the grain fertilizer, the function of the leaf is always strong, and the prevention and treatment of premature aging should promptly supplement the nitrogen fertilizer. The potassium fertilizer or urea can also be used for foliar topdressing to maintain and extend the functions of the leaves above the middle, lower and ear positions. Time, make more compounds, promote grain formation, and make the seeds full, 1000-grain weight increase; foliar spray dihydrogen phosphate 1.5 kg, 100 kg per acre of water.
Watering the slurry and watering the corn to the milky stage requires more water. If it is dry in this period, it should be irrigated in time to increase the seed setting rate, promote the water operation and increase the grain fullness.
Interlaced stagnation in time to remove males, can increase the ear length and ear weight, increase the rate of double ear, the plant is relatively short, the ventilation and light transmission in the field is improved, the photosynthetic productivity is increased, and the yield is increased.
Pest control 1. Corn aphid: spray with 2000% to 4000 times solution of 10% imidacloprid wettable powder or 2000~2500 times of 3% acetamiprid emulsifiable concentrate. 2. Corn bran: Use 1.8% avermectin EC 20~40 ml or 20% phoxim EC 200~250 ml to control the spray of water 40~50 kg. 3. Corn size spot disease: spray with 70% methyl thiophanate 1000 times solution or 75% chlorothalonil powder 1000 times solution. 4. Corn rust: 20% triazodone EC 75-100 ml or 12.5% ​​diniconazole wettable powder 60-70 g per acre, spray 30-40 kg water.
