| 摘 要： | 文章首先综述了水稻施用硅肥后增产的机理，以及施用硅肥对水稻的叶片、植株、根系和抗逆性产生的积极影响，然后对水稻施用硅肥的增产效果以及增产幅度与土壤有效硅含量的关系作了总结，认为各地区施用硅肥的增产幅度存在差别，且北方一般高于南方；不同土壤类型，缺硅临界值应不同，并提出了华北平原的缺硅临界值为250mg/kg。最后，对今后的研究趋势作了论述。

| Abstract: | On the base of consulting large amount of science and technical references, this article summarized the mechanism of output increasing and quality improving of the silicon fertilizer application to rice, reached the conclusion that the application of the silicon fertilizer not only can produce good effects on the ecology of rice blades, roots and resistance to disadvantage, but also can improve the utilization ratio of phosphate and nitrogenous fertilizers. This paper also compared the relation between the effective silicon content of soils and the effectiveness of increase production of the silicon fertilizer application to rice, found that there are different ranges of increase production in different soils and it is higher in northern soils than in southern soils. It concluded that there are different critical values of silicon deficiency in different soil types. It is 250mg/kg in Huabei Plain. At last the paper tell the method of the silicon fertilizer application to rice and the study trend. |
