摘　　要：深翻技术需要新型深翻犁来保证。土壤深翻对土壤培肥有长期效果。采用随机区组实验表明:随着种植年限的增加,心土上移对作物的产量和品质影响逐渐变小,培肥沟机械改土处理在第一年小麦田上产量比前松后旋处理低4.80%,比深翻处理高6.22%;在第二年大豆田上产量比前松后旋处理略高,比深松处理高10.56%,同时通过机械改土,土壤物理性质发生改变,最终起到培肥心土。The deep tillage skill depends on new deep -plow. Deep tillage is good for soil fertility. Ran- domized block experiment show that with the increase of planting age, the subsoil moving effect becomes small on crop yield and quality. The fertility ditch mechanical soil improvement treatment can reduce output 4.80% then ＂plane and whirl loosening＂ method and increase 6.22% than deep tillage method, in wheat field the first year. The output continues increasing at the second year in soybean field. Accompanied mechanical soil improvement treatment, the physical properties of the soil can be changed to lay a role in fertility subsoil and improve crop yield at last.
