| Abstract: | Crop straw,which contains abundant organic substance and large numbers of elements such as N,P,K,Mg,Ca,S,etc,returned to soil would be in favor of improving physic-chemical properties of soil,enhancing soil fertility and improving crop growth.However,the ecological effect was markedly different between different treatments and sometimes had negative effect. |
