摘　　要：以中黄35和垦鉴豆43为材料,采用4个硅肥水平处理的完全随机试验设计,研究了大田条件下施硅处理对大豆碳代谢及其产量形成的影响。结果表明:施硅处理提高了大豆叶片的叶绿素含量,增加了叶片的光合能力,改变了叶片可溶性糖和淀粉的含量,改善了大豆产量构成因子,促进了产量提高。施有效硅150 kg·hm-2对垦鉴豆43增产效果达显著水平,增产幅度为8.1%～8.5%,施有效硅120 kg·hm-2对中黄35增产效果达显著水平,增产幅度为10.2%～12.9%。Field experiment was conducted to investigate the effect of silicon （Si）on the carbon metabolism and the yield of Kenjiandou 43 and Zhonghuang 35 and to provide a basis for using silicon to the soybean production. The result showed that the chlorophyll content was increased, the photosynthesis was improved, and the soluble sugar and starch were changed with the application of Si. The soybean yidd was increased with Si,especially the yield of Kenjiandou 43 and Zhonghuang 35 were sig- nificantly increased by 8.1%-8.5% and 10.2%-12.9% with 150 and 120 kg·hm-2 Si,respectively.
