    摘要:

    針對華北平原小麥、玉米一年兩熟區(qū)固定道保護性耕作缺乏配套機具,,設計了2BMDF-2/7型固定道小麥/玉米免耕播種機。該機利用固定道實現(xiàn)對行作業(yè),同時采用動力驅(qū)動粉碎防堵機構(gòu),,重點解決玉米秸稈地免耕播種小麥的問題。試驗結(jié)果表明,,該機通過性好,,對行避茬率在85%以上,能很好地解決玉米秸稈地免耕播種小麥的堵塞問題,,可以完成小麥和玉米的免耕播種,,播種深度變異系數(shù)分別為19.4%和23.4%,實現(xiàn)一機兩用,。

    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.
