“枣丰素”叶面肥对冬枣产量、品质和耐贮性的影响

The Influence of Winter-date Production,Quality and Storability by Spraying Zaofengsu Foliar Fertilization of Chitin Derivatives

利用"枣丰素"叶面肥对冬枣产量、品质和耐贮性的影响进行了试验。结果表明:125mg/kg浓度的"枣丰素"对冬枣果实含糖量、产量增加显著,果实在自然条件下货架期最长;喷施100、150mg/kg浓度的"枣丰素"对冬枣果实含糖量、产量增加不显著;在自然条件下货架期与对照比较,喷施100mg/kg浓度的冬枣果实有所延长,喷施150mg/kg浓度的冬枣果实较对照几乎没有延长。

In order to improve Winter-date trees＇nutrition,enhance quality and yield of jujube,the research group have been made a test on the yield,quality and storability of Winter-date by spraying chitin derivatives,which is based on the Winter-date leaves growth and fruit enlargement and disease resistance test.The results showed that spraying 125 mg/kg concentration ＂Zaofengsu＂ have been increased significantly on the fruit sugar content and production.Under the natural conditions,the fruits of spraying 125mg/kg concentration have the longest shelf life.Either the 100mg/kg or the 150mg/kg concentration ＂Zaofengsu＂ on the fruit sugar content,yield increase was not significant.Under the natural conditions,the shelf life of the 100mg/kg concentration has been extended and the concentration of 150mg/kg was little extension.
