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茎叶形态与抗倒伏特性的影响。结果表明:硅肥能改善超级早稻茎叶形态与抗倒伏能力,主要表现为提高单茎叶面积,减小剑叶夹角,增粗茎秆,缩短基部一、二节间,增强抗倒力等,且在施氮150 kg/hm2条件下施硅效果最好,且陆两优996抗倒性提高更好。

关 键 词:早稻  施肥  硅肥  茎叶形态  抗倒伏

Abstract:The effects of silicon fertilizer on morphology and characteristics of lodging resistance in super early hybrid rice were investigated in this study with Zhuliangyou 819(Lodging sensitive hybrid) and Luliangyou 996(Lodging resistant hybrid) as materials.The main conclusions were showed that silicon application would strengthen morphology and lodging resistance in early super hybrid rice through mainly incresing the leaf area and stem diameter,decreasing the leaf angle of the flag leaf,shortening the first a...
