Abstract:: Study on the effect of successive plant ing soybean to nut rient , Chlorophyll , Photosynthetic eff iciencyand photosynthetes w as conducted .The result showed that continuous cropping soybean af fected soil condit ionand soybean plant developing which resulted to the NO3 -N , avilable P , avilable K chlorophyll .Photosyntheticeff iciency , soluble sugar and arnimo acids decreasing.So that the pho tosy nthetic effioiency and o rganic matteraccumultaion were affected , which resulted to soybean g rain yield decreasing , w ith the years of successive plantingsoybean in creasing , the tread of g rain yield decreasing w as more obvious .The result also show ed that plantingsoybean every oter two years w as bet ter than that every o ther one year , however w hich w as bet ter than thatsuccessive planting soybean .
