摘 要：
采用休眠期强力注射黄叶绿制剂 (YL G)进行缺铁黄化症的防治试验。结果表明 ,注射 YL G制剂后黄化级平均为 0 .2级 ,比对照下降 2 .76级 ,复绿明显。处理单叶面积增加 3.5 cm2 ,比叶重增加 0 .88mg/ cm2 ,叶绿体各色素含量极显著增加 ,其中总叶绿素增加 2 .2 6倍 ,净光合速率增加 2 7.6 % ,叶内 N,P,Zn,Fe和活性 Fe极显著增加 ,K,Ca,Mg,Mn,Cu和 B等含量下降 ,但均在标准值范围内。处理使果实产量提高 34.5 % ,单果重增加18.32 % ,可溶性固形物和可溶性糖极显著增加 ,果实品质明显改善 ,花芽分化率和花芽质量也明显提高

摘 要：
The correction of iron deficiency was studied by pressure injection of YLG fertilizer in dormancy period.The results showed that chlorotic rating scores was 0.2 on average after injection,and decreased by 2.76,so the effect of regreening was obviously.The individual leaf area and leaf dry weight/leaf area ratio increased by 3.5 cm 2 and 0.88 mg/cm 2 respectively.The chloroplast pigments all increased,for example,the total chlorophyll increased by 2.26 times.Net photosythesis rate increased by 27.6%.the content of N,P,Zn,Fe and active Fe increased,and the others(K,Ca,Mg,Mn,Cu,B)decreased.The yield per tree increased by 34.5%,individual fruit weight by 18.32%.Firmness of flesh,soluble solids and soluble sugar all increased obviously,so the fruit quality improved.Floral bud differentiation rate and floral bud quality increased too.
