含钙营养剂对木枣裂果防治效果及对木枣部分品质的影响

摘要

[目的]研究含钙营养剂对木枣裂果防治效果及对木枣部分品质的影响。[方法]以木枣为试验材料，对其树体挂瓶输送含钙营养液，采用田间调查与室内浸枣相结合的方法，对其裂果率、果实大小、果实重量、VC 含量进行检测和分析。[结果]适宜浓度的含钙营养液可降低木枣裂果率，增加果实横径、纵径及单果重，提高果实VC 含量。[结论]以浓度为0．024～0．032 g／mL的含钙营养液处理效果最好。%Objective] To research the effects of calcium nutrition agent on fruit cracking control and quality of jujube.[Method] With wood jujube as the experimental objects, calcium nutrition agent was transported into the tree by suspended bottle.Field investigation and indoor ju-jube soaking were combined together.The fruit cracking rate, fruit size, fruit weight and VC content were detected and analyzed.[ Result] Calcium nutrition solution in proper concentration reduced the fruit cracking rate, enhanced the fruit transverse and longitudinal diameters, and single fruit weight, and enhanced the fruit VC content.[Conclusion] 0.024 -0.032 g/mL calcium nutrition solution has better treatment effects.
