| Abstract: | After having analyzed the results of manuring silicon fertilizer to rice and composition data of soil samples for the years(1988～19999)in Yunnan,relativity between effective silicon in soil,manuring levels and efficiency of silicon fertilizer was studied.Abundance and shortage index of silicon in soil for increasing silicon fertilizer to rice was proposed,as well as optimization of manuring levels. |
