混合根瘤菌对蒙农S007饲用大豆的固氮效应
- Title:
- Nitrogen Fixation Effect of Mixed Rhizobia on Hybrid Forage Soybean Mengnong S007
- 摘要:
- 为了解不同根瘤菌混合接种对蒙农S007饲用大豆的影响，并筛选出与蒙农S007匹配性高的根瘤菌组合，选择3株分离自试验地种植小区中蒙农S007根部根瘤的根瘤菌，在室内无菌蛭石条件下，将根瘤菌接种到蒙农S007上，30 d后测定蒙农S007的地上生长指标、地下生长指标、根瘤特征、叶绿素含量和植株全氮含量，对各指标进行相关性分析与主成分分析，评价不同根瘤菌组合对蒙农S007的影响，筛选与蒙农S007匹配性最高的根瘤菌组合。结果表明：蒙农S007与不同根瘤菌组合的共生匹配性和固氮能力存在差异；接种根瘤菌后，蒙农S007叶绿素含量、根瘤重、植株全氮含量与地上生物量呈显著正相关；对各根瘤菌组合接种下，蒙农S007各生长指标进行主成分分析并进行综合排名，相较于单一根瘤菌接种，根瘤菌混合接种下的植株得分更高，处理G（Sf-8+ Sf-74+ Sf-134）下的植株综合表现最优。结果表明接种Sf-8、Sf-74和Sf-134根瘤菌组合能显著增加蒙农S007固氮效应，促进蒙农S007叶片叶绿素含量、植株全氮含量、株高、根瘤数、根瘤重、根长和地下生物量的增加，从而使得蒙农S007地上生物量显著增加。
