According to Xiaobian, the corn planting process, corn row spacing needs to be controlled, because the species too dense will lead to uneven nutrient absorption of corn, reducing the normal planting yield, but this year the Ministry of Agriculture in the Northeast to guide corn planting an acre seedling 4500- 5000 strains, which surprised Xiaobian. Below is a detailed corn planting technique from the Ministry of Agriculture. You can learn to learn.
At present, the temperature in the northeast region has gradually recovered, and the spring sowing work has begun. The Ministry of Agriculture and Rural Affairs directly issued a document to guide northeast corn planting. The paper proposes that in the plots with better comprehensive production conditions, it can be planted in accordance with 4500-5000 strains of mu seedlings. Friends, the land of your home, do you dare to plant such a secret? At present, the temperature in the northeast region has gradually recovered, and the spring sowing work has begun. In response to the requirements of China's corn production adjustment structure and transfer mode, combined with the current climate characteristics of the Northeast region, the Agriculture and Rural Ministry corn expert guidance group and the National Agricultural Technology Extension Service Center proposed to “timely land preparation, scientific selection, timely fine broadcasting, and reasonable close plantingâ€. The prevention and control of pests and diseases will focus on the spring sowing corn technology path, and promote corn production to increase production and increase efficiency, improve quality and efficiency, and save costs and increase efficiency.
Prepare the seeds in time for land preparation. Pay close attention to the changes in the weather, seize the favorable opportunity of better soil moisture in the near future, and prepare for ploughing and timely land preparation, and create conditions for suitable sowing and sowing seedlings. For the autumn plot, it is necessary to suppress the deposit in time. For spring land and spring drought-prone areas, it is necessary to make full use of the soil re-slurry water, and to rectify the land as soon as possible. For the low-lying land and the spring-prone areas, it is necessary to clear the ditch early and use the conditions such as spring temperature rise and windy conditions to carry out ploughing, drying and digging, and ensuring timely sowing.
Scientific selection to ensure seed quality. According to the conditions of light and heat resources in various places, the layout of scientific varieties and reasonable maturity. Choose the high-yield, stable, disease-resistant and insect-resistant, high-resistance, high-efficiency, and mechanized operation of the fine varieties that have been approved by the national or provincial level. The maturity of the varieties should be appropriate, and the planting in the cross-region should be eliminated to ensure safety and maturity. In the corn structure adjustment area, it is necessary to select the high-quality special-purpose or grain-feeding silage corn varieties that are suitable for local cultivation through national or provincial inspections, and vigorously develop order production. Pay attention to the purchase of high-quality coated seeds to prevent pests and pests in the underground pests and seedlings, and improve the emergence rate and group uniformity.
Improve the quality of seeding in a timely manner. According to the temperature, soil moisture and growth period of corn varieties, determine the best sowing date, timely and suitable for mechanical sowing, so that the use of seeds is accurate, the seeds are even, the depth is consistent, the fertilizer is isolated, the soil is tightly sealed, the suppression is moderate, and the sowing is improved. Quality, fight for a seed to protect the seedlings. In areas with moderate soil moisture, mechanical ditching, fertilization, sowing, ridges, and repression operations are completed at one time, soil agitation is reduced, and soil moisture is maximized. For areas with high soil moisture and low ground temperature, ridges should be erected earlier, the ground temperature should be raised, shallow or shallow soil should be properly applied, and the weather should be suppressed every other day. For areas with poor soil moisture or drought, it is possible to adopt water-saving and drought-resistant sowing techniques such as plastic film mulching, drip irrigation under water, water and fertilizer integration, or to carry out ditch planting, flat sowing, and no-till seeding. For areas with severe drought conditions, “sit water†can be adopted.
Reasonable close planting to optimize group structure. According to the characteristics of the varieties and the actual production in each place, determine the appropriate planting density, construct a reasonable group structure, and lay a foundation for the capture of high yield. Under the general production conditions, there are about 4000 seedlings per mu. For soil fertility, high fertilization level, irrigation conditions, suitable conditions, good overall production conditions, and the use of dense maize varieties, the mu seedling density can be increased to 4500-5000.
Control pests and diseases and promote green production. According to the analysis of the National Agricultural Technology Extension Service Center, the occurrence of major diseases and insect pests in the country will be heavier than normal in 2018. The corn borer, armyworm, underground pests and large spot disease in the northeast region are seriously harmful. On the basis of using resistant varieties of corn and high-quality coated seeds, we should strengthen the dynamic monitoring and forecasting of pests and diseases, timely grasp the development trend of pests and diseases, and support the green prevention and control and biological prevention and control technologies. Anti-rule, improve the effect of prevention and control, reduce the use of chemical pesticides, and promote green production.
The corn planting technology guided by the Ministry of Agriculture is indeed a cow. An acre can actually protect 4,500-5,000 plants. It seems that this year's corn planting in Northeast China will have a bumper harvest.
