摘要
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 comparison,lodging resistance of soybean were analysed with comprehensive evaluation method,in which bending strength,elasticity modulus and stiffness were selected as evaluation index,and seven kinds of soybean stalks were chosen as research objects.The result showed that the differences of bending strength,elasticity modulus and stiffness of stalks were significant and lodging resistance of these soybean varieties in descending order were 621,1357,625,726,Willims2,ZP03-6025 and 1305.The results will provide reference for breeding varieties of soybean with lodging resistance.
