Spring corn full mechanization high yield and high efficiency
Scale, standardization and mechanization are the only way for China's modern corn production. Densification planting and full mechanization are important ways for high yield and high efficiency of corn. The key technologies of reasonable dense planting, precision on demand, mechanical fertilization, mechanical spraying, straw returning, mechanical harvesting and other key technologies are used as cores for years of demonstrations in Xinjiang Construction Corps and Heilongjiang Reclamation Area. Based on the formation of high-yield corn planting full-scale mechanized production technology. Technical points: 1. Select the varieties that are dense, resistant to fall, and suitable for mechanical harvesting. Select the varieties that have been examined and approved by the country or province, have been planted in the local area and have excellent performances of density resistance, lodging resistance, adaptability to mechanical precision on demand, and mechanical harvesting. The direct receipt of grain machinery requires the rapid dehydration in the later period and the fertility period is 5-7 days. 2. Density planting. According to the local climatic conditions, soil conditions, production conditions, species characteristics and production purposes, reasonable spacing arrangement, to ensure the appropriate density. The light conditions in the northwest region are relatively good. Generally, mid-late and late-maturing varieties retain 6000–6500 plants/mu; mid-early-maturing varieties are 7000–7500 plants/mu. The early-maturing varieties in the northeast region range from 6000 to 6500 per mu, and the medium-maturing varieties range from 5000 to 5500 per mu. 3. Use mechanical precision sowing. Single seed sowing rate should be higher than 96%. Through adequate planting, appropriate sowing, etc., to ensure Miao Qi, Miao uniform, Miao Quan, Miao Zhuang, improve the uniformity of the group. When seeding with seed fertilizer, seed and fertilizer are separated. 4. Fertilization by stages. According to the local corn production target and fertility level, soil testing and formula fertilization were conducted, and formulas or special formula fertilizers recommended by soil-fertility stations at all levels were used. In areas where conditions permit, apply 2 to 3 tons of high-quality organic fertilizer per acre or 1 ton of refined organic fertilizer; use all phosphate fertilizers, 30% to 40% of nitrogen fertilizer (reduced dosage if there is seed fertilizer) and 70% of potash fertilizer as base fertilizer. . The remaining fertilizer is subjected to a one-time mechanical top dressing before the small bellmouth period. 5. Chemical control and prevention. For plots often lodging and areas with high density, overgrowth, and poor lodging resistance, spraying control chemicals, such as jade gold, Teng Tianbao, and hydroxyethele, can be applied during the 6-8 leaf stage of maize. , Control the internode length of the base, enhance the strength of the stalk, and prevent lodging. 6. timely late harvest, mechanical harvest. According to the planting distance and the quality of the work required to choose the appropriate harvesting machinery. Corn can be harvested after ripening. Grain mechanical harvesting can be harvested 2 to 4 weeks after physiological maturity (grain lining disappears completely). The grain moisture content should be below 28%. Once the panicles are harvested, stripped and threshed, and the stalks are treated (segmented). Silage or smashed into the field) and other operations. 7. Straw returned to field, fertility and fertility. Use forage grass picking and tying machine to bale the straw for feed, or use the straw returning machine to smash the straw. Turn the plow to the ground, depth 30 to 40 cm. Puyang Linshi Medical Supplies Co., Ltd. , https://www.linshihealths.com
