摘要
通过对盐渍土施用硅肥后土壤及作物中氮、磷、钾、硅等营养元素的分析,发现施硅肥后土壤中的碱解氮、速效磷、速效钾和有效硅含量都有明显提高,小麦茎杆和籽粒中的氮、磷、钾、硅的含量也比对照处理的含量高,小麦抗逆性、光合作用等都有明显改进,增产幅度达22.7%;最后简要说明了硅肥对盐渍土的改良作用。
The effects of silicon fertilizer on rice are obvious. In this paper, we studied the effects of silicon fertilizer on wheat and reached the conclusion that the application of silicon fertilizer on wheat not only could improve the effective tillering of wheat, its effective stachys, the grain per stachys, actual grain and the weight of kilogram and some other biological features, but also could enhance the power of drought_resistant and disease_resistant, the photosynthesis of wheat was improved too. In this paper we also analysed the nutrition elements such as nitrogen, phosphorous, potassium and silicon in soil and wheat. The result indicated that the contained quantities of these elements are all increased after silicon fertilizer was used in the salt and alkaline land. The output increasing range reached to 22.7%. As a result, the silicon fertilizer has the effect of improving salt and alkaline land.
