【摘要】 在试验推广深松少耕法的过程中,从八种耕作措施中筛选出用小铧杆尺深松犁,进行浅翻间隔深松,浅翻7—8厘米,间隔35厘米,深松20—35厘米,创造的虚实并存的耕层(虚实比8∶4),由于表土位置不变,水、肥、气、热协调,增产效果稳定,种小麦、大豆平均增产分别为21.6%和15.5%;而且还有节省油料、降低成本,不用大量增添新的耕作机具的优点,并具有明显的抗旱、抗涝、防止土壤风蚀、水蚀的结果。更多还原

【Abstract】 In the course of the extension of subsoiling mini-till,small shar-ed subsoiler is screened from 8 kinds of tillage practices to carry outshallow plowing and interval subsoiling,shallow plowing is 7-8 cmdeep.and at the interval of 35 cm,the subsoiling is 20-35cm deep.Thus,the co-exitence of loose and compact tilths is created(ratiobetween the loose and compact tilths is 3:4).Owing to the unchan-ge of surface soil position,water,fertilizer,aeration and heat are incoordination,and yield increase is stable.when wheat and soil beansare planted,the yield increase is 21.6% and 15.5% respectively.Mean-while,the other advantages of this technique are to save feul,lowercost and use less farm machinery.This technique is of important andapparant effects to resist droughts and water logging and preventwind and water erosion.更多还原
