以7个品种(系)大豆秸秆为研究对象,在弯曲试验和多重比较分析的基础上,以秸秆弯曲强度、弹性模量和刚度为评价指标,应用综合评价分析方法,对大豆抗倒伏性能进行了分析研究。结果表明,各品种秸秆弯曲强度、弹性模量和刚度存在显著性差异;供试大豆品种抗倒伏能力由强到弱依次为621、1357、625、726、Willims2、中品03-6025、1305。研究结果为大豆抗倒伏品种选育提供了参考依据。
Based on the bending test and multiple comparative analysis, the straw bending strength, elastic modulus and stiffness of seven varieties (lines) of soybean straw were taken as the research object. The comprehensive evaluation method was used to evaluate the lodging resistance of soybean Analytical research. The results showed that there was a significant difference in bending strength, elastic modulus and stiffness between different varieties of straw. The ability of lodging resistance of tested soybean varieties was 621,1357,625,726, Willims2, Zhongmao 03-6025,1305. The results provide a reference for selection of soybean lodging resistant varieties.
