1玉米机械化收获是机械化生产的薄弱环节玉米是辽宁省第一大粮食作物,近年播种面积已达200万hm2以上。随着科学技术水平的提高,加之劳动力流失,玉米生产过程机械化程度逐渐提高。土地流转政策的实施使得原来影响机械化进程的土地因素将逐渐解除,必然进一步加速机械化生产的发展。农机补贴政策的实施也增加了农民购置农机的积极性,购机成本的降低还加速了大型先进机械的推广应用。但玉米生产机械化主要还是集
1 Mechanized harvest of corn is the weakest link in mechanized production. Maize is the largest food crop in Liaoning Province. In recent years, the sown area has reached more than 2 million hm2. With the improvement of science and technology, combined with the loss of labor, the degree of mechanization of corn production process gradually increased. The implementation of land transfer policy makes the original land factors that affect the mechanization process will be gradually lifted, and will inevitably further accelerate the development of mechanized production. The implementation of subsidies for agricultural machinery has also increased the enthusiasm of peasants to purchase agricultural machinery. The reduction of purchase cost has also accelerated the popularization and application of large-scale advanced machinery. However, the main mechanization of corn production is still set
