| 摘 要： | 1999－2000年连续2年试验研究表明：黔中黄壤丘陵旱坡地分带轮作水土保持效益优于净作，分带轮作制中洋芋（油菜或小麦）／绿肥／玉米／红薯轮作方式优于油菜（小麦）／绿肥／玉米／大豆；不同作物轮对对产量的影响小季以洋芋＞油菜＞小麦，大季以红薯＞大豆；适宜的分带轮作制为洋芋（或油菜）／绿肥／玉米／红薯，其水土流失量小，作物总产量最高。

Effect of Different Cultivation Rotation System on Soil and WaterConservation in Yellow Sloping Upland Areas of Middle Guizhou |
| |
| Abstract: | Two years experimental results showed that the effect of soil andwater conservation with rotation system was superior to single cropping.The manner of intercropping potato (rape or wheat) with green manure in Winter and corn with sweet potato in Summer was better than that of interplanting rape (or wheat) with green manure and corn with soybean. The proper rotation system which had the lowest water erosion and the highest total crop yield was intercropping potato (or rape) with green manure and corn with sweet potato. |
