利用作物秸秆实行机械化覆盖免耕播种,在北美和欧洲一些国家已大面积应用,而在国内由于受到生产水平的限制至今仍未推广。国营农牧场机械化水平较高,机械覆盖免耕有广阔应用前景。据此,我们于1986、1987两年在大曹庄农场进行试验研究,现报告如下:
The use of crop straws for mechanized coverage of no-till sowing has been applied extensively in some countries in North America and Europe, but has not been popularized domestically as it is restricted by the level of production. State-owned farms mechanization level is higher, no-tillage machinery has broad application prospects. Accordingly, we conducted pilot studies at Daocaozhuang Farm in 1986 and 1987, and are reported as follows:
