| 摘 要： | 经１９９３￣１９９４年的田间试验证明，重迎茬大豆经ＡＢＴ生根粉处理后，能提高出苗率，降低土壤中孢囊线虫孢囊数量，减轻大豆孢囊线虫病害，增加苗期根际细菌及根瘤菌数量，增加根数，根重，根瘤重量、干物质积累，单株籽粒数量及产量，其产量与正茬对照相当，具有保产作用。

| Abstract: | Two years' field test showed that continous and rotation croping soybean treated byABT can effectively reduce the percentage of soybean cyst nematode disease and the cyst number ofsoybean cyst nematode in its root area,increase the percentage of seedling,the number of bacteria andrhizobia in the root area during the stage of seedling,the number of root,the weight of root and rootnodule,the accumulation of dry matter and the number of seed per plant. Consequently,ABT groWthpromoter can increase the yield of continous and rotation croping soybean,their yield near to that ofnormal croping soybean,and have the effect of stabilizing yield on continous and rotation croping soybean. |
