| 摘 要： | 以华夏3号大豆为材料,在大田条件下控制硅肥的施用量,研究硅肥对大豆的叶绿素含量(SPAD值)、叶面积指数(LAI)、农艺性状、产量及品质的影响.结果表明,硅肥能增加大豆叶面积指数(LA1)、株高、总荚数、有效荚数、百粒重,减少无效荚数,降低植株的倒伏率；对大豆倒3叶SPAD值无显著性影响.同时,与对照相比,施用硅肥处理...

| Abstract: | An experiment was carried out in the field to study the effects of Silicon fertilizations on SPAD,leaf area index(LAI),agronomic traits,yield and qualities of soybean Huaxia No.3(Glycine max L.).The results showed that Silicon could increase soybean LAI,plant height,total pod number,the number of valid pods,100-seed weight,and decrease invalid pods,plant lodging rate.However,there was no significant difference in leaf SPAD.Compared with CK,the Silicon fertilization increased soybean yield by 11.97%-32.56% and soybean protein content by 1.07%-2.04%,but significantly decreased oil content by 1.68%-3.61%.The results suggested that Silicon fertilizations with proper quantity can effectively enhance soybean production. |
