| 摘 要： | 在东北黑土区（１９９１年￣１９９４年）设置大豆不同轮作方式定位试验。结果表明重茬三年较正茬大豆减产３５．３５％，迎茬较正茬减少５．４９％；重茬和迎茬大豆生育期间干物质积累均低于正茬；重茬大豆叶面积指数较正茬降低，迎茬较正茬变化不大。重茬大豆与正茬大豆相比蛋白质含量有降低趋势。

| Abstract: | The field experiments which include different rotations in chernozemic soil area of North East from 1991 to 1994 were conduted. The results showed that continuous soybean cropping reduced soybean yield seriously. Yield of soybean-soybean is 18. 61% less than that of normal rotation. Yield of there-year continous soybean cropping is 35.35% less than that of normal rotation. Yield of cropping of soybean afternating with another crop is 5. 49% less than that of normal rotation. Dry matter accumulation of soybean follows soybean and soybean afternating with another crop is less than that of normal rotation. Soybean leaf area index of continuous cropping is less than that of normal rotation. Comparing with normal rotation cropping, Soybean of continuous croppins has a trend of protein content deduction. |
