Résumé
Straw mulching and subsoiling can protect soil and improve soil structure. However, long-term continuous subsoiling cannot continuously gain yield increasing and soil improvement. To realize continuous soil improvement and yield enhancement, a long-term experiment on subsoiling alternation patterns was carried out with spring maize continuous cropping in the Loess Plateau in 2007-2016. The subsoiling alternation patterns were no-tillage/conventional tillage/subsoiling (NT/CT/ST) and subsoiling/conventional tillage (ST/CT), with continuous subsoiling (ST) as control. We analyzed the effects of the different patterns on soil physical and chemical properties and maize yield. The results showed that, compared with the ST, the mechanical-stable aggregates (DR 秸秆覆盖深松耕能保护土壤并调节土壤结构,但长期连续深松并不能获得持续增产与培肥土壤效果。为实现持续培肥增产的目的,于2007—2016年在黄土旱塬区连作春玉米田进行了深松轮耕长期定位试验,设置免耕/翻耕/深松(NT/CT/ST)与深松/翻耕(ST/CT)轮耕处理,并以连续深松(ST)为对照,对比分析不同耕作模式对土壤理化性质和玉米产量的影响。结果表明:与ST相比,NT/CT/ST处理机械稳定性团聚体(DR
