| 摘 要： | 针对我国北方旱作地区春玉米播种时墒情不够、肥力不足的问题,提出了在秋季收获后进行深开沟、沟内铺放秸秆、覆土起垄整垄、垄上覆膜的秸秆深埋,蓄积秋冬降水的土肥水跨季节联合调控技术。研制了秸秆深埋还田开沟扶垄犁。采用对称式可翻转犁架,实现开沟、覆土、起垄、整垄联合作业。田间性能试验结果表明:该机开沟深度可以达到40cm,沟形规整,覆土效果较好,整垄效率高,垄形符合农艺要求。采用该机进行秋季秸秆深埋还田,可以有效提高土壤水分含量,提高玉米产量。 |
| 关 键 词： | 秸秆还田 深松 土壤水分 覆膜 旱作玉米 |

| Abstract: | Zn northern China,soil moisture content and fertility are low at the time of maize planting.A solution was proposed for this problem.After harvesting in the autumn,the soil was tilled to create deep furrows filled with straw and backfilled to form ridges mulched with a plastic film.A plough was designed to furrow the soil properly,bury the straw deeply,form ridges with a suitable shape,and to puncture the membranes for spring seeding.The rotary plough with a symmetrical frame was developed,built and tested.... |
| Keywords: | straw amendments deep tillage soil moisture content mulching dry land maize planting |
