【摘要】 在田间栽培条件下 ,研究花生结荚后期叶面喷施 ABT生根粉对促进花生后期根系活力及叶片光合性能的作用。研究结果表明 ,应用 ABT生根粉明显提高花生根系活力 ,增加后期功能叶片的叶绿素含量 ,使叶片保持较高的光合速率。ABT2 0 mg/ L处理综合效果较好 ,在生产上可作为促进花生生育后期生长发育的一项技术措施更多还原

【Abstract】 The effect of application ABT root developed powder to the leaf surface in late growth stage on the root system and photosynthetic properties of leaf were investigated under field condition. The results indicated that ABT could improve the activity of root system obviously, increase the chlorophyll content of leaves and keep more photosynthetic rate in the leaves during late growth stage when it was used 20mg/L. So, application of ABT was a technical method of increasing peanut yield.更多还原
