| 摘 要： | 以超级早稻组合株两优819(倒伏敏感品种)与陆两优996(抗倒伏品种)为材料,研究了硅肥对超级早稻产量形成和生理特性的影响.结果表明:硅肥对超级早稻具有显著增产作用,株两优819与陆两优996增产幅度分别为6.71％～18.25％和9.32％～21.89％.增产的主要原因在于施硅肥提高了叶面积指数与干物质积累量及物质转换率,协调了库源关系；硅肥能改善超级早稻生理特性,主要表现在叶片叶绿素含量、可溶性总糖含量与硝酸还原酶活性的提高及根系体积的增大等方面；施氮150 kg/hm2条件下施硅肥的增产和改善生理特性效果更好,且陆两优996效果比株两优819更好. |

| Abstract: | Effects of silicon fertilizer on physiological characteristics and yield formation of super early rice were investigated in this study with Zhuliangyou819(lodging sensitive variety) and Luliangyou996(lodging resistant variety) as materials.The main conclusions were showed: Yield of super early rice was heightened by silicon fertilizer application at some extent,yield of Zhuliangyou819 and Luliangyou996 was increased by 6.71% to 18.25% and by 9.32% to 21.89% respectively,and the yield-increasing was mainly d... |
