1, check seedlings, replanting, breeding seedlings. For lack of seedlings, ridges should be replanted in time or transplanted with soil, seedlings should be seeded at appropriate times, generally 3 leaf seedlings, 4 to 5 leaf seedlings, and seedlings should be seeded and seedlings should be required by density to stay strong and weak. 2 seedlings, to ensure the improvement of the level of the group.
2, timely cultivator weeding, earth training. Remove the weeds in the field, eradicate factors such as competing for fertilizers and competing for water, and ensure that corn (2434, 0.00, 0.00%) has sufficient fertilizer and water.
3, right amount of top dressing. According to the growth of corn, Qiao Shi raises Miao Fei, applies 20-25 kilograms of urea per acre, or 30-40 kilograms of carbonic ammonia, and increases the use of foliar fertilizers and plant growth agents in response to the slow growth of corn seedlings. Apply foliar potassium dihydrogen phosphate in fine weather, generally 150 grams per mu, and spray 30 kg foliar. Application of plant growth regulators to ensure more income, with 10 ml per acre, watering 15 kg foliar spray, at the same time, combined with cultivator, do a good job during corn jointing fertilizer, mu recovery urea 12.5 ~ 15 kg, top dressing from the plant 8 ~ 12 cm, depth 10 ~ 12 cm is appropriate. For zinc-deficient maize plots, zinc supplementation is needed immediately. The method is to use 0.3% zinc fertilizer solution per mu, foliar spray, and about 20 kg per mu solution.
4, do a good job of pest control. The main diseases are large leaf spot, small spot disease, etc. It can be sprayed with 50% Triflumne wettable powder and 70% chlorothalonil wettable powder 300 to 500 times spray. Insect pests mainly include small ground tigers, corn borers, aphids, etc., and can be sprayed with 2.5% enemies to kill 20 to 30 ml/mu and 80% fipronil 30 to 50 ml/mu for spraying.
5. Remove no effect spikes. Early removal of immature spikelets in double spikes ensures that one ear and one ear can both reduce nutrient consumption, concentrate nutrient supply to the main spike, and promote early maturation.
