不同果袋对石榴果实生长的影响

［目的］研究纸袋和膜袋2种果袋对石榴果实生长的影响，为提高石榴果实品质提供技术参考。［方法］在石榴果实发育特定时期进行果实套袋（纸袋或膜袋），测定果实纵横径，计算石榴果实体积和净增长，对比纸袋和膜袋对石榴果实生长的影响。［结果］纸袋石榴果实体积增长较膜袋石榴果实快，纸袋石榴果实体积净生长出现1个生长高峰，但纸袋石榴果实裂果明显；膜袋石榴果实成熟期较纸袋果实晚，发育时间长，膜袋石榴果实体积净生长出现2个稳定生长期,2个生长高峰。［结论］临潼地区石榴果实套袋，应以膜袋为主，纸袋为补充；或者采用纸袋＋膜袋的方式，前期套纸袋，后期套膜袋。

Effect of the Different Bags on Pomegranate Fruit Growth

Objective] The technical reference for the improvement of pomegranate fruit quality was provided through the study on two kinds of fruit bags:paper and film bag,affecting pomegranate fruit growth.Method] The size of pomegranate fruit and its net volume were calculated through the diameter-measuring of its fruit,which was bagged by paper and film bag in the specific growth stages,respectively,and then,the effect of two kinds of fruit bags on the pomegranate fruit growth of were compared.Result] The volume...
