春小麦盆钵试验结果表明，在土壤有效硅含量低于５１１．２ｍｇ／ｋｇ的供试土壤上，施用硅肥均表现不同程度的增产，最高增产率达３２．８％。春小麦施硅后，植株全氮、全磷、全钾含量均比对照增加，而锌、锰含量分别比对照降低。植株体内二氧化硅含量与春小麦的生物及籽粒产量呈正相关 The result of spring wheat pot experiment showed that the application of silicon fertilizer showed different degrees of yield increase in the test soil with available soil silicon content less than 511.2mg / kg, with the highest increase rate of 32.8%. After silicon fertilization in spring wheat, the content of total nitrogen, total phosphorus and total potassium increased more than that of the control, while the content of zinc and manganese decreased respectively. The content of silicon dioxide in plants was positively correlated with the biomass and grain yield of spring wheat
