石榴果实不同纸袋套袋比较试验

选择4种纸袋对石榴果实进行套袋处理。采果时对不同处理的烂袋率，石榴的烂果率，果品质量等性状进行比较分析。结果得出4种处理石榴的可溶性固形物，优质果率等性状表现无差异。但4种纸袋间的烂袋率均存在极显著差异。鹏程单层纸袋对烂果率的影响与青木双层，凯祥双层和鹏程双层纸袋有显著性差异。生产上建议推广西昌鹏程双层纸袋和山东凯祥双层纸袋。

A Comparative Experiment on Punica granattum with Different Paper Bag Coverings

In this experiment,four different kinds of paper bags were used to cover fruits on Punica granattum trees.When picking the fruits,the authors carried out a comparative experiment on such traits as damage rates of paper bags,damage rates of Punica granattum fruits and fruits quality.The resalts have shown that these four kinds of paper bags have made little difference in the soluble solid matter contents or rates of super-quality fruits,but there is a significant difference in damage rates of paper bags,especially significant between Pengcheng single-layer paper bags and Qinmu and Kai-xiang and Pengcheng double-layer paper bags.Therefore,it is suggesed that Pengcheng double-layer paper bags made in Xichang and Kaixiang double layer paper bags made in Shandong be used in production.
