在稻麦轮作条件下，潮土、水稻土上的硅肥试验表明，施硅水稻增产９．５９％，小麦增产１３．９％。稻季施硅在小麦上后效明显，增产８．２％；硅肥对水稻的氮素吸收有促进作用，亩吸氮量增加２．９５ｋｇ，氮素吸收率提高１４．８个百分点。水稻植株性状得到改善，基部节间缩短，剑叶、倒二叶叶面积增加；硅肥对水稻具有增穗、增粒作用，抽穗后灌浆速率提高，千粒重也有明显增加；小麦表现为增穗、增加千粒重。硅肥宜作水稻基肥或返青肥，作中期长粗肥效果较差，每亩用量以颗粒速效硅肥１０ｋｇ为宜。
Under the conditions of rice and wheat rotation, soil fertility and paddy soil fertilization experiments showed that silicon fertilization increased 9.59% and wheat increased 13.9%. Silicon fertilizer in the rice season significantly after the effect, yield 8.2%; silicon fertilizer on nitrogen absorption of rice to promote the role of acres of nitrogen increased 2.95kg, nitrogen absorption rate increased 14.8 percentage points. Rice plant traits improved, the basal internodes shortened, flag leaf, leaf area of the second leaf increased; Silicate fertilizer had increased ear, grain effect, increased grain filling rate after heading, grain weight also increased significantly; Increase 1000 grain weight. Silica fertilizer should be used as base fertilizer or turn green rice, for the medium-term coarse fat less effective, per acre amount of granular quick-acting silicon fertilizer 10kg appropriate.
