提出土壤深松机具经历了3个演化进程的观点,研制成 1SO-250型全方位深松机。大面积田间试验结果表明,该机松土阻力小,作业深度稳定性好,深松后土块尺寸、土壤体积密度等完全符合农艺要求,并能显著提高土壤渗透能力,完整地保持土表植被覆盖,而且在松土层底部形威2条纵贯作业行的鼠道。生产试验结果表明,使用该机可使一般旱地玉米的平均增产率达到20.23%,棉花16.7%,涝洼地冬小麦增产率达到100%。 It is proposed that soil subsoiling equipment has undergone three evolutionary processes and developed into a 1SO-250 all-directional subsoiling machine. The results of large-scale field experiments show that the machine has less resistance to loosening soil and good working depth stability. Soil mass, soil bulk density, etc. are fully in line with agronomic requirements after deep loosening, and can significantly improve the soil infiltration capacity and completely maintain the soil surface vegetation Cover, but also in the bottom of the loose soil shape Wei 2 walk through the operation of rats Road. Production test results show that the use of this machine can make the average dry land yield of corn increased by 20.23%, 16.7% cotton, waterlogged areas of winter wheat yield increased to 100%.
