摘要
水稻从土壤中吸收很多硅，水稻植株中硅含量２．３６％～６．４７％，土壤中有效硅为３５０～３７０ｍｇ／ｋｇ．为保证水稻对硅肥需要，施用硅肥非常重要．试验证明，施用硅肥不但能增加水稻高度、分蘖数、抗倒伏能力、抗病能力，而且也能提高产量．
Rice plants contain 2.36%～6.47% of silicon and they uptake large amount of the eiement from soil.The contcnt of avallable silieon in the soil is 350～370 mg/kg.To meet the requirement of the rice for silicon,it is important to apply silicon fertilizer.This experiment showed that application of silicon fertilizer not only increased the plant hight,the number of tillers,the resistance to lodging and disoase,but also inereased the rice yield.
