1. Production infrastructure. The land, water source and atmosphere are non-polluting, the soil is fertile, the soil layer is deep, the soil permeability is good, the water source is sufficient, and the irrigation and drainage facilities are available.
2. Variety selection and seed treatment. The large-ear type varieties promote Jinhai No. 5, Denghai 3707, Ludan 981, etc., and the dense and compact varieties are promoted by Ludan 984, Liaoyu 19, Zhengdan 958, Ludan 9006, and Ludan 9002. The seed treatment selects a high-efficiency, low-toxic and pollution-free corn seed coating agent such as 5.4% pyridoxine, or a seed dressing.
3. Seeding quality. 5 to 7 days before the wheat harvest, the seedlings or wheat harvest should be raked in time, and the corn should be timely watered after the corn is insufficient. The seeding rate is 25-3 kg/mu. When the line spacing is 50-65 cm, when the size is large, the line spacing is 80-90 cm, and the small line spacing is 30-40 cm.
4. Reasonable close planting. The dense and compact corn varieties are 4200~4700 plants/mu, and the large panicle varieties are 3200-3700 plants/mu.
5. Rational fertilization. High-yield fields shall be applied with nitrogen (N) 3 kg, phosphorus (P2O5) 1 kg, and potassium (K2O) 2 kg for each 100 kg of grain, and the amount of fertilizer required for the zinc-deficient plot shall be increased by 1 kg per mu. The seedling fertilizer is about 30% of the total nitrogen fertilizer before the jointing of the corn plus all the phosphorus, potassium, sulfur and zinc fertilizers. The panicle fertilizer is about 50% of the total nitrogen in the big bell mouth of the corn, and the grain fertilizer is in the grain filling stage. Topdressing 15% to 20% of total nitrogen. When the special fertilizer for slow-release of sulfur-containing corn is selected, it is applied once at the seedling stage.
6, irrigation and irrigation, cultivating. Irrigation water should meet the non-polluting requirements. In addition to the seedling period, the water holding capacity of the field should be watered in time if it is reduced to less than 60%. Combine fertilization with cultivating before jointing. The corn is afraid of cockroaches, and the flooding time should not exceed 0.5 days. The late flooding time should not exceed one day.
7. Comprehensive prevention and control of pests and diseases. The focus is on chemical weeding and pesticides to control pests and diseases.
8, timely harvest. When the corn matures, the grain milk line basically disappears, the base black layer appears when it is harvested, and it is dried in time after harvesting. It is suitable for promotion in high-yield areas of maize in Shandong Province.
