在参考大量文献的基础上，综述了套袋、反光膜和棚膜对桃果实大小的影响，以期为进一步开展相关研究和生产较大果实提供依据。重点对不同类型果袋对果实大小的影响进行了分析，讨论了套袋后果实单果重变化的几种情况及原因分析、不同类型果袋对果实大小的影响及棚膜对果实大小影响的复杂性，并建议进一步系统开展套袋对果实大小影响的研究。“,”Referring to a large number of literatures, the effects of bagging, reflective film and greenhouse film on fruit size of peach were reviewed in this paper so as to provide basis for conducting relevant researches and producing larger fruits. The effects of different types of bags on fruit size of peach were analyzed. The weight variation of single fruit after bagged was investigated, and the relevant reasons were analyzed. In addition, the complexity of effect of greenhouse film on fruit size was also discussed. It is proposed that further comprehensive study on effect of bagging on fruit size should be carried out.
