袋型与套袋时间对日面红梨果实及贮藏品质的影响

目的]为提高红皮梨的品质提供理论依据，以促进红皮梨推广工作健康发展。【方法]以红皮梨品种日面红为试验树，以5种盲果袋分3个不同时期对日面红进行套袋试验。结果]套袋可减少果锈，其中以双黑袋和条黑袋效果最好，套袋晚者好；套袋后绿色减退、表色鲜艳。套袋过早日烧增加，以膜＋纸袋最严重。套袋后裂果增加，以塑膜袋最重，套袋晚的三色袋和膜＋纸袋较轻。套袋后果实黑点病增加，塑膜袋最严重，套袋越晚越严重。除双黑袋和三色袋外，套袋后着色下降。套袋早的，采收后失水严重，以三色袋、膜＋纸袋最严重。结论]综合比较，以5月下旬（盛花后40～45d）套双黑袋和条黑袋的日面红果实贮藏品质最优。
