吉林省敦化市现有粮食作物面积1 6.2万hm~2,其中大豆、玉米和水稻3大作物面积1 5.9万hm~2,耕地面积已经没有增长的空间。随着农业产业结构的调整,稳定粮食播种面积难题在加大,因此加快推进传统农业向现代农业的转变,把机械深松整地技术作为提高农业综合生产能力,提高地力的战略举措,也是粮食增产农民增收的有效手段。应用机械深松技术可以加深耕层,打破多年由于机械碾压而形成的犁底层(目前敦化市犁底层
Dunhua City, Jilin Province, has an existing grain crop area of 102,200 hm ~ 2, of which 3,900 hm ~ 2 are the major crops of soybean, maize and rice, and the cultivated area has no room for growth. With the adjustment of agricultural industrial structure, the difficulties in stabilizing the sown area of grain are increasing. Therefore, the transformation from traditional agriculture to modern agriculture is accelerated. Taking the mechanical subsoiling and land preparation technology as a strategic measure to improve the comprehensive productivity and enhance the productivity of agriculture, Effective means of increasing farmers’ income. The application of mechanical subsoiling technology can deepen the topsoil, breaking the years due to mechanical rolling plow bottom (currently Dunhua Plow bottom
