摘要
以优质粳稻品种稻花香2号为材料,研究了立丰灵对其抗倒伏能力及产量和品质的影响。结果表明,在拔节前10d叶面喷施立丰灵能显著降低株高,不同程度缩短基部3个节间长度、增加茎粗及茎鞘中可溶性糖和钾、硅含量,显著增加茎秆基部各节间的抗折力,从而提高茎秆的抗倒伏能力,而且能提高产量,且对稻米品质没有不良影响。
Using Daohuaxiang gling were studied on lodging 2, a japonica rice variety with good grain quality, as material, the effects of Lifenresistance, grain yield and quality. The results showed that Lifengling, when topdressed 10 days before jointing stage, decreased significantly plant height, shortened three basal internodes and thickened their stems and increased the contents of soluble sugar, silicon and potassium in stem and leaf sheath to some extent, and increased significantly the lodging resistance force of basal stem internodes, resulting in an improvement of lodging resistance of plants. It was also found that, compared with the control, the treatment of Lifengling top-dressed 10 days before jointing stage increased grain yield （5.11% ） but had not negative effects on grain quality.
