| 摘 要： | 重、迎茬大豆对黑土和暗棕壤的影响为;有机质,重组有机质,复合有机质及复合度均为重,迎茬低于正茬,石灰性黑钙土则相反;复合体中不同结合态腐殖质及Ｅ４／Ｅ６变化不尽相同;水稳性团聚体在三种土壤中重,迎茬呈下降趋势,重迎茬对土壤结构有损伤。

| Abstract: | The affect of soybean continuous and alternate cropping on soil fertility was studied in this experiment. The results shows that organic matter, heavy fraction organic matter, complex organic matter and complex degree of Black soil and Dark brown forest soil in continuous and alternate cropping were all lower than those of rotation cropping, but those of Calcareous chernozem was opposite. The humus of different combining form and its E4/E6 of HA in soil complex have their own variation forms. The content of waterstable aggregate in soil where soybean was cropped continuously and alternately had decreasing tendency. The soil structure was damaged by soybean cropped continuously and alternately. |
