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
Under the field cultivation conditions, the effects of foliar application of ABT rooting powder at the late peanut pod stage on promoting root activity and photosynthetic capacity of late peanut were studied. The results showed that application of ABT rooting powder significantly increased the root activity of peanut and increased the content of chlorophyll in functional leaves in later stage, and maintained the higher photosynthetic rate. ABT2 0 mg / L treatment is better, and can be used as a technical measure to promote the growth and development of peanut
