摘要
在陕西石灰性土壤秦美猕猴桃果园施用不同剂量叶绿灵 (Fe- EDDHA) ,结果表明 ,萌芽期株施 45 g叶绿灵对矫治秦美猕猴桃叶片失绿黄化效果显著 ,可一直维持到当年落叶。同黄化对照植株相比 ,叶片叶绿素含量增加 1 82 .5 % ,活性铁含量提高 5 3 .2 % ,果实品质得到明显改善。
The effectiveness of different doses Fe EDDHA on correcting Qinmei kiwifruit leaf chlorosis was evaluated during two consecutive years following soil drench in calcareous soil in Qinmei kiwifruit orchards in Shaanxi Province.The results showed that the leaf can be turned green significantly with 45 g Fe EDDHA per tree when the leaves are unfolding,the content of chlorophy and active iron in the leaf has increased by 182.5% and 53.2% respectively,the fruit quality also was improved.The mineral element contents between green and chlorotic leaves in kiwifruit orchards were discussed.
