摘要
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％。
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%.
