增施硅肥对玉米产量及产量构成因素的影响

Effects of Increased Application of Silicon Fertilizer on Maize Yield and Yield Components

为研究硅肥对玉米产量及产量构成因素的影响,以先玉335为试验材料,设置4个硅肥模式,0(CK)、基施硅肥(S1)、喷施硅肥(S2)、基施硅肥+喷施硅肥(S3),分析3种硅肥施用方式对玉米干物质积累、产量及产量构成因素和玉米籽粒品质变化特性的影响。结果表明,硅肥显著增加了玉米干物质积累量,其中,S3处理的穗粗、行粒数、穗粒数、千粒质量和产量显著高于对照组,且产量提高10.33%。和对照组相比,硅肥可显著提高籽粒脂肪和蛋白质含量,降低淀粉含量,同时硅肥处理间没有差异。综上,硅肥基施+喷施效果最好,能够提高玉米产量、改善玉米品质。

In order to study effect of silicon fertilizer on maize yield and yield components,Xianyu 335 was used as a test material.Four silicon fertilizer models were set,including 0(CK),basic silicon fertilizer(S1),sprayed silicon fertilizer(S2),basic both silicon and silicon fertilizer spraying(S3).Three silicon fertilizer application methods on dry matter accumulation,yield and yield components of corn,and characteristics of corn grain quality were analyzed.Results showed that silicon fertilizer significantly increased corn dry matter accumulation,ear thickness,row number,ear number,thousand kernel weight and yield of S3 treated were significantly higher than control,yield increased by 10.33%.Compared with the control,silicon fertilizer significantly increased grain fat and protein content,starch content was significantly reduced and there was no difference between silicon fertilizer treatments.It showed that the best effect of silicon fertilizer base application+spraying could increase corn yield and improve corn quality.
