机械化深松按作业性质可分为局部深松和全面深松两种。全面深松是用深松犁全面松土,这种方式适用于配合农田基本建设,改造耕层浅的土壤。局部深松则是用杆齿、凿形铲或铧进行松土与不松土相间隔的局部松土。由于间隔深松创造了虚实并存的耕层结构,实践证明,间隔深松优于全面深松,应用较广。在生产中应用的土壤深松方法主要有间隔深松、垄沟深松、中耕深松、浅耕深松、垄翻深松、全面深松等。按作业机具结构原
Mechanized deep loose by job nature can be divided into partial deep loose and comprehensive deep loose two. Full deep pine is fully loose with deep plowing, this method is suitable for farmland infrastructures, transformation of shallow soil topsoil. Partially loose is the use of pole teeth, chisel-shaped shovel or Hua loosening and loosening of the local loose soil interval. Due to the subsoiling interval, the plow structure that created the coexistence of the actual situation and the actual situation proved that the interval subsoiling is better than the comprehensive subsoiling and has a wide range of applications. The method of soil subsoiling used in production mainly includes subsoiling spacing, deep furrows, deep plowing in cultivation, subsoiling in shallow tillage, subsoiling in deep plowing, deep subsoiling and so on. According to the original structure of work tools
