摘 要:以发生叶片黄化的10年生贝达砧巨峰为试材,采用NAA+IBA灌根、叶面喷施氨基酸、叶面喷施络合铁3个处理,30 d后,通过观察叶片长势、颜色,测定成熟叶柄中氮、磷、钾、铁、锌元素的含量,使用Li-6400光合作用测定仪测定叶片的净光合速率、气孔导度等指标,统计新根数量等方法来判定试验的有效性。结果表明:采用NAA+IBA灌根后,新根总量显著增加,植株全铁、全锌含量显著提高,叶片光合效率明显增强,新生叶片转绿,植株生长势增强;其它两个处理也有一定效果,但以灌根处理效果最为显著。The corrective effects of pouring root with NAA+IBA, foliage spray with amino acids and chelated iron on 10-years-old Kyoho grapevine which had many yellow leaves were studied. 30 days later, the validity of the tests were determinated by observing the leaf growth vigor and color, the contents of N, P, K, Fe, Zn, the photosynthetic rate and the new root number, etc. The results show that pouring root with NAA+IBA had the best corrective effect with the number of new root improved, the content of Fe and Zn increased, the photosynthetic rate higher and plant growth vigor stronger. The other two treatments also had some corrective effects, but pouring root with NAA+IBA had the most significant effect for new leafvirescent.
