Abstract:

The affect o f so ybean co ntinuous and al terna te cro pping on soil fertility w as studiedin thi s ex periment. The result s show s that o rganic mat ter, heav y f ractio n organic matter,complex o rg anic mat ter a nd complex deg ree o f Black soil a nd Dark brow n 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.
