| 摘 要： | 在吉林省德惠市中层黑土上进行了不同耕作方式对玉米和大豆产量及土壤质量影响的田间试验。3年的试验结果表明：保护性耕作（免耕）的玉米产量为10507kg／hm^2，略高于常规秋翻下的玉米产量（10196kg／hm^2），且2002年免耕玉米产量明显高于其它处理。同样，免耕大豆的3年平均产量（2777kg／hm^2）也显著高于秋翻管理下的大豆产量（2563kg／hm^2）。

| Abstract: | Conservation tillage practices are alternative measures to conserve and restore black soil productivity in Northeast China. In order to test the impacts of conservation tillage as well as no-tillage practices on soil quality and crop production in Northeast China, a tillage trail was established on a black soil (silt loam) in Dehui, Jilin province in 2001. Three-year studies (2002-2004) showed that conservation tillage did not result in the decline of corn yield. Average corn yield under conservation tillage was (10 507 kg/hm~2) greater than that under moldboard plough which was 10 196 kg/hm~2. Average soybean yield under no-tillage was 2 777 kg/hm~(2) greater than that under moldboard plough. |
