Abstract:

This experiment was conducted inHailun Agriculture Ecological Experiment Station , CAS since 1991 with site-specific different rotation system including continuous soybean (SSS …S), soybean -wheat -soybean (SWS), soybean- corn -soybean(SCS), wheat -soybean -soybean (WSS)and wheat -soybean -soybean -soybean(WSSS).The results of the site -specific field experiment showed that the weed density and weed fresh weight were the largest inSWS and were the least in SCS.In different year the weed population were different in same plots .Some weed populationappeared in SSS …S .The weed fresh weight were the largest in SWS .
