摘要：采用ＥＤＤＨＡ?Ｆｅ在高钙、高ｐＨ值土壤柑桔园进行连续两年试验表明，土壤施用ＥＤ?ＤＨＡ?Ｆｅ可以矫治钙质紫色土中枳砧柑桔树的缺铁黄化症，成倍地提高叶绿素含量，一般连续两年较大剂量处理后，黄化症状可基本消失，明显增加单株果实产量，对甜橙果实品质有良好影响的趋势。在ＥＤＤＨＡ?Ｆｅ的两种剂型中，叶绿灵的效果优于绿喜旺，较大剂量施用的效果优于低剂量。认为土壤施用ＥＤＤＨＡ?Ｆｅ是目前矫治缺铁黄化症效果最理想的途径之一。

Abstract: Iron deficiency chlorosis(FeDC) cause the leaf chlorosis and extensive reduction in fruit yields of citrus plants on poncirus trifoliata rootstock grown on high pH calcareous soil. Effects of two EDDHAFe products, Rexolin Q and Rexiron, on the scales of leaf chlorosis, contents of leaf chlorophyll, yield and qualities of citrus fruits of the plants with iron deficiency chlorosis in the calcareous purple soil were investigated in 3 testing areas in Sichuan Province and Chongqing Municipality, China during 19971998.EDDHAFe products were applied two times in the soil under the canopy during flowering period. The results showed that EDDHAFe treatments significantly decreased the chlorosis scales on the leaves and increased the contents of leaf chlorophyll and fruit yield as compared with the plants treated with sulphus powder or control treatment. It seems that the better results were obtaiued from the applications of Rexolin Q than that of Rexiron. The higher the dosages were applied via soil, th
