田间和盆栽试验表明，紫色水稻土施用有机肥，有效硅可提高１０％～３５％，水溶性硅增加６％～１０４％，并促进了水稻植株对硅的吸收，使水稻产量提高。＞Ｌ，ｓ．Ｄ０．０５＝１．７６，０．１＝２．６７，达极显著水平，更证明了有机肥不仅是提供植物硅素营养的良好肥源，而且有利于水稻产量的提高。３结语施用有机肥可以提高土壤有效硅含量，促进水稻植株对硅的吸收。所以，在有效硅缺乏的酸性紫色水稻土中，可通过施用硅含量较高的有机肥（如稻草等）来提高土壤中的硅素营养。参考文献
Field experiments and pot experiments showed that the application of organic manure on purple paddy soil increased the available silicon by 10% -35% and the water-soluble silicon by 6% -104%, and promoted the absorption of silicon by rice plants and increased the yield of rice. > L, s. D0.05 = 1.76,0.1 = 2.67, reached a very significant level, but also proved that organic fertilizers not only provide a good source of plant silicon nutrients, but also conducive to the improvement of rice yield. 3 Conclusion Organic fertilizers can increase soil available silicon content, promote rice plant silicon absorption. Therefore, in acidic purple paddy soils lacking effective silicon, organic fertilizers (such as straw) with higher silicon content can be used to improve the silicon nutrition in the soil. references
