以“新川中岛”桃为试材,研究了不同材质果袋、不同脱袋时间对桃单果重、果实着色、可溶性固形物、去皮硬度等性状的影响。结果表明:套纸袋优于塑膜袋,套纸袋果实可溶性固形物含量、硬度与无袋果差异不明显,可溶性固形物含量甚至略高于无袋果,脱袋时间以采前5~7d为宜;套纸袋后带袋采收的桃果较无袋栽培果可溶性固形物含量变化不大,不影响果实的甜度、口感等。 With “Xinchuanzhongdao” peach as test material, the effects of bagging with different materials and different time of bagging on peach fruit weight, fruit coloring, soluble solids and peeled hardness were studied. The results showed that: the paper bag is superior to the plastic film bag, the content of soluble solids in the paper bag is not obvious, and the content of soluble solids is even slightly higher than that of the bagless fruit. The time for taking off the bag is 5-7 days Appropriate; bagged bagged bagged peach fruit bagless cultivated fruit soluble solids content changed little, does not affect the fruit’s sweetness, taste and so on.
