几种生物有机硅肥在水稻上应用效果研究

摘要

Fertilizer contrast test on August first agricultural university,Doctor xu,Leader science and technology of Qinhuangdao and Sanxing Agricultural four biological siliceous fertilizer by large area field contrast test, The result shows that using siliceous fertilizers can raise rice resistance in a certain degree, but is not conspicuous; using siliceous fertilizer can province and add rice production. During four siliceous fertilizers, the one of August first agricultural uniliversity has the notable effect of increasing production, the production is 605.5 kg/667 m^2 with using silioeous fertilizer in hase fertilizer, 55,4 kg/667 m^2 higher than the contrast.%采用大区对比的方法,对八一农大、许博士、秦皇岛领先科技、佳木斯三兴4种生物硅肥开展了肥效对比试验。结果表明,施用硅肥能在一定程度上提高水稻抗病性,但效果不显著;施用硅肥能有效提高水稻产量构成因子,实现增产作用。四种硅肥中,八一农大生物硅肥增产效果最明显,基肥施硅处理产达605.5 kg/667 m^2,比对照增加55.4 kg/667 m^2。
