China's corn production mechanization further highlights the year

Rapid progress in the overall rapid Shandong took the lead in breaking the "three autumns" this year. China's main corn producing areas have invested in 189,000 corn combine harvesters and completed an aircraft harvest area of ​​168 million mu, which is an increase of 40 million mu over the previous year. The national corn harvest rate exceeds 33%. It has been growing at a rate of more than 7 percentage points for two consecutive years in a row. The corn harvester has developed rapidly, the corn harvest area has grown steadily, and the operation level has increased significantly. This has again become a highlight of the development of agricultural mechanization this year. ,

As Shandong province, the advanced province of maize production and mechanization, this year, the corn harvested area was 3,371 million mu and the machine yield reached 80.8%, an increase of 9.3% over the same period of last year. Breakthrough momentum is overwhelming. Among the 17 cities in Shandong, the yield of corn machines has reached over 70%, of which 9 cities exceed 80%.

At the same time, corn harvesting in all major corn producing provinces also raced to speed up, showing an overall rapid development momentum. In Henan Province, more than 6,100 new corn harvesters have been added, and the corn harvesting area has reached 23 million mu. The corn yield has reached about 50%, and has achieved rapid growth for four consecutive years. Based on the development of 2,000 corn harvesters last year, Shanxi has newly developed 2,700 corn harvesters this year. During the "Three Autumns," a total of more than six million mu of corn harvesters were harvested, and the machine harvesting level increased from 17% to 26%. In Inner Mongolia, 2347 new corn combine harvesters were added, and the machine harvest rate reached 17.3%, which was 6.6 percentage points higher than last year. The corn harvest rate in Shaanxi reached more than 36%, an increase of 6 percentage points from last year.

Break through the bottleneck of technology to create development conditions Although the development of mechanization of corn production has become a major highlight of this year, it cannot be denied that there is not enough integration of agronomic techniques and mechanization techniques such as corn breeding, cultivation, plant protection and harvesting, especially the complex and diverse forms formed under the traditional farming system. The mode of cultivation has restricted the development of corn harvest mechanization. In view of this, in the fall of this year, the Department of Agricultural Mechanization Management of the Ministry of Agriculture, the Department of Science and Technology Education, and the Department of Crop Management jointly convened a national symposium on the integration of maize production, agronomy, and agronomy.

At the symposium, on the basis of experience and inspiration from the integration of foreign corn production and agronomy and agronomy, the participating experts discussed and analysed the corn planting patterns and agronomy and agglomeration of the agricultural machinery in Northeast China, Northwest China, Huanghuaihai, and Southwest China, and harvested them from corn. Mechanization of key technologies and equipment from the perspective of agronomy and integration of agricultural machinery in-depth analysis. In view of the Huang-Huaihai corn production area, some experts suggest that the wheat will be changed from corn to maize in the summer, which will be conducive to the improvement of the degree of mechanization of corn production, increase the density and uniformity of corn planting, and avoid flowering pollination period to avoid adverse climate Conditions can also significantly increase corn production and increase planting efficiency. Maize planting in Northeast China can improve yield through rational dense planting, improved ploughing, fine seeding, canopy optimization, and fertilizer and water optimization; southwest China should choose drought tolerance, temperature resistance, resistance to dampness, disease resistance, lodging resistance, and resistance to drought. Stains and varieties suitable for machine broadcast and harvesting. Experts believe that the integration of maize production and agricultural agronomy must implement the standardization and standardization of corn planting agronomics and harvesting modes. Advanced and efficient supporting units can only fully exert their use efficiency under standard and standard agronomic conditions.

In order to further promote the development of corn production mechanization, on November 17, the Ministry of Agriculture formulated and issued the "Maize Production Mechanization Technical Opinions". The Guiding Opinion focuses on the technical issues that restrict the development of corn mechanization, highlights the agronomy and technology integration of agricultural machinery, and puts forward specific technical specifications for such aspects as species selection, seed treatment, site preparation before planting, sowing, cultivating, cultivating, plant protection, water-saving irrigation, and harvesting. All localities are required to base on the technical guidance, combine local realities, refine the technical content, strengthen publicity, training and guidance, actively carry out corn production mechanization tests and demonstrations, and vigorously promote full standardization of corn production.

The comments emphasized that all localities should focus on the unity of regional planting spacing, gradually standardize corn planting, explore a rational production model for full mechanization, and improve the maize production mechanization technology system and operating specifications appropriate for the region, so as to create conditions for the full mechanization of corn production.

Supporting Demonstration and Promoting Development Each has its own coups. While the Ministry of Agriculture has issued various measures to promote the development of corn production mechanization, various localities have also actively sought financial support and adopted various forms of measures to continuously promote the rapid development of corn production mechanization.

In addition to tilting the corn harvester’s purchase subsidies, this year in Henan province, it also imposes a cumulative subsidy on the corn harvester. The purchasers can also receive an accumulated subsidy of around 20,000 yuan on the basis of enjoying the national capital subsidy of 30%. .

Some cities and counties in Henan Province also provided a subsidy of RMB 15 per mu for corn machine harvesting operations in the corn harvesting demonstration area. Jiyuan City will provide a 600 yuan fuel subsidy to corn harvesters who participate in the “three autumns” operation, with a stand-alone operation area of ​​200 mu or more. A series of policy incentives greatly mobilized the enthusiasm of farmers for purchasing corn harvesters. In the process of developing corn harvesting, Henan Province also selected regional key breakthroughs to guide the classification and classification of corn harvesters in different regions, and strived to achieve breakthroughs in the advancement area, key promotion areas, and key counties, and lead the rapid development of corn harvesting in the province.

In Jiangsu Province, an expert group on corn production mechanization was established to technically support the development of corn production mechanization. Through detailed implementation of the provincial government's promulgation of agricultural machinery purchase accumulative subsidies and operation subsidy policies, Shanxi Province has fully mobilized the enthusiasm of farmers for the development of corn harvesters. During the “Three Autumns” period, the Shanxi Provincial Bureau of Agricultural Machinery also guided 60 counties to sign a pair and sign contracts, and invested more than 6,000 corn harvesters to carry out cross-regional operations, achieving remarkable results.
