【Abstract】 Effect of silicon on effective nutritive element in soil was examined. It is shownthat silicon is able to rise supply ability of N,P,K,as well as regulate the ratio of iron andmanganese and supply of Ca,Mg,Zn,Mn. When applied quantity of silicon is fitly,it enablesto increace the production of sugarcane and its sugar content.更多还原
