Technical Overview: Select middle and late-maturing high-yielding and close-tolerance new corn varieties (fertility period 105-110 days), change the wheat crops intercropping corn for no-tillage live wheat after harvest; appropriate dense planting, establish a reasonable group structure, ensure population density and uniformity, resistance Dense maize seedlings were planted with 4500-5000 plantings/mu, and compact big panicle plants were planted with 3500-4000 plantings/mu; the grain milk line disappeared and was harvested when it was ripe. Increase production and efficiency: Corn adopts a no-tillage direct seeder for standardization and standardized sowing, which can not only grab robbers but also ensure the planting density. When harvested when corn is ripe, it can make full use of limited light and heat resources and increase production. Compared with the wheat set of corn, the yield is increased by 15% to 20%, ie, 100 to 150 kg/mu. At the same time, it can reduce the occurrence of corn roughage virus disease. Technical points: 1. Variety selection. The selection of medium and late-maturing high-yielding and low-density maize varieties requires that the post-flowering population has a long duration of photosynthetic growth, strong tolerance to planting, strong resistance, a growth period of 105 to 110 days, and an effective accumulated temperature of 1200°C to 1500°C. 2. After the wheat is harvested, the corn is no-tillage, the seeds are sowed, and the seeds are planted closely. When the wheat combine harvester is operating, the wheat straw is crushed and sprinkled on the surface of the ground, and the summer corn is used for no-tillage precision sowing of a fertilizer applicator, and the free (less) cultivation is performed to complete the ditching, fertilizing, sowing, covering the soil and suppressing the one-stop operation. The sowing depth is 3 to 5 centimeters, and the species and fertilizer are separated by more than 8 centimeters. Watering after sowing when the sensation is not enough can be achieved. According to the characteristics of the selected corn varieties, the appropriate density is ensured: the compact middle ear maize seedlings are planted with 4500-5000 seedlings/mu, and the compact large ear seedlings are preserved with 3500-4000 seedlings/mu. 3. Balanced fertilization. When the former winter wheat is full of organic fertilizer (3000kg/mu), the fertilizer is mainly used; the amount of fertilizer is determined according to the yield; the high-yield field uses 2.5kg of pure nitrogen per 100kg of grain, and phosphorus pentoxide 1 Kilograms, potassium oxide 2 kilograms; balanced nitrogen, sulfur, phosphorus nutrition, formula fertilization. In fertilizer management, light Miaofei, reapply large mouth fat, make up for flowering grain fertilizer. Special fertilizer for slow and controlled release of sulphur-containing corn can also be used. 4. Comprehensive prevention and control of diseases, weeds and weeds, and mechanical pesticide application. Chemical weeding at the seedling stage after sowing, or at the 3 to 5 leaf stage of corn and at the 2 to 5 leaf stage of weeds, the active ingredients are selected to be herbicides such as nicosulfuron and atrazine for post-emergence weed control; and comprehensive pest and disease control measures are strengthened. According to the occurrence of major local diseases and insect pests, select the appropriate fungicides and insecticides, determine the reasonable dose, and actively use elevated spray equipment, drones, etc. for mechanical pesticide application, improve work efficiency, and reduce labor intensity. 5. timely harvest. In the past, “the yellow leaves of the loquat leaves became harder and the seeds became harder to be harvested†as the harvest of the dried loquat leaves, the formation of black layers, and disappearance of the milk line. At the same time, wheat was sown around October 10th to ensure that wheat and corn were harvested at full harvest year-round. Note: The wheat corn will be changed to no-tillage live after wheat harvesting, organically combined with no-tillage live harvesting and appropriate harvesting, supplemented by relevant supporting technologies to achieve high-yield and high-efficiency corn production.
