水稻施用硅肥方法的研究

水稻施用硅肥试验表明，氮磷硅肥配合施用比单施氮肥生育期提前3d,分蘖率提高86．5％，增产19．4％；比氮磷肥配合施用生育期提前4d，分蘖率提高115．5％，增产10．6％；比氮硅肥配合施用生育期提前1d，分蘖率提高70．5％，增产6．0％。

A Study of Si Fertilizer Application Method on Rice

The results of the study of Si fertilizer application method on rice showed that rationallyapplying N. P. Si fertilizer compared with only applying N fertilizer, the growing periods was improved by3 days, the tiller rate increased by 86.5%, the yield incmeing was 19 .4%. Compared with rationallyapglying N. P fertilizer, the growing periods was improved by 4 days, the tiller rate increased by115.5%, the yield increasing was 10. 6%. Compared with rationally applying N. Si fertilizer, thegrowing periods was improved by 1 day, the tiller rate increased by 7.05%, the yield increasing was6.0%.
