    摘要:

    针对华北平原小麦、玉米一年两熟区固定道保护性耕作缺乏配套机具,设计了2BMDF-2/7型固定道小麦/玉米免耕播种机。该机利用固定道实现对行作业,同时采用动力驱动粉碎防堵机构,重点解决玉米秸秆地免耕播种小麦的问题。试验结果表明,该机通过性好,对行避茬率在85%以上,能很好地解决玉米秸秆地免耕播种小麦的堵塞问题,可以完成小麦和玉米的免耕播种,播种深度变异系数分别为19.4%和23.4%,实现一机两用。

    Abstract:

    To solve the problems of blocking and lacking outfitting machinery in wheat no-till planting in corn residue under controlled traffic conservation tillage farming system in annual two-crop region of northern China, the 2BMDF-2/7 row-followed no-till wheat and maize planter for controlled traffic system was designed. Combing of row-followed operation to sheer off corn stubble by using wheel tracks and power driven chopping anti-blocking mechanism, it can be used to solve the problem of no-till wheat planting in corn residue. Field test shows that the planter has a good performance of trafficability with the ratio of sheering off corn stubble 85% and anti-blocking capacity, thus to finish wheat and maize no-till planting. The variation coefficient of seed depth was 19.4% and 23.4% for wheat and maize, respectively. This machine can implement both wheat and maize no-till planting. Therefore, this planter can be a good solution to current problems in no-till planting in annual two-crop region of northern China.
