树干注入络合铁肥矫治缺铁黄化李树的效果

Effect of Trunk Injection with Complex Iron Fertilizer for Correction of Iron Chlorotic Plum Trees

研究评价了对李树树干注入络合铁肥矫治缺铁性黄化症的效果。注铁后，不仅叶内的全铁、活性铁及叶绿素含量显著增加，而且提高了其氮、磷、镁、锰、锌的含量及降低了钾、钙、硼的含量。文章比较了元素间的相关性及处理与正常叶间的关联性。

This study was undertaken to evaluate the effect of trunk injection with complex iron fertilizer for correcting iron chlorosis of 6-year old plum trees in mid-June. Afterinjection, not only the contents of total Fe, active Fe and chlorophyll increased significant,but also increased the contents of N, P, Mg, Mn, Zn and reduced the contents of K, Ca, B in leaves. Both of correlativity between elements and cognate coefficient between each treatment and normal leaves were discussed.
