摘　　要：[目的]研究不同用量的有机硅大量元素水溶肥对水稻生育的影响。[方法]通过田间试验,设置5个有机硅大量元素水溶肥用量,分别为600、750、900、1 050 kg/hm2,分析不同有机硅大量元素水溶肥用量条件下,水稻的分蘖、产量、抗逆性等。[结果]施用有机硅大量元素水溶肥可促进水稻分蘖,利于物质积累,增加产量,改善稻米品质。[结论]有机硅大量元素水溶肥用量以900~1 050 kg/hm2增产效果好,考虑成本以900 kg/hm2的施用量最佳,增产显著。[Objective]Effects of different dose of macro-element organic silicon water soluble fertilizer on the growth of rice were studied.[Method]Through field experiment,5 kinds of dose of macro-element organic silicon water soluble fertilizer(600,750,900,1 050 kg/hm2)were set,effects of different dose of macro-element organic silicon water soluble fertilizer on tillering,yield and stress resistance of rice were analyzed. [Result]Macro-element organic silicon water soluble fertilizer could promote rice tillering and favor for the material accumulation,which improved the yield and rice quality. [Conclusion]The usage of 900-1 050 kg/hm2 of macro-element organic silicon water soluble fertilizer showed positive effects on the yield increment,and the dose of 900 kg/hm2 significantly increased the yield considering of the costs.
