摘　　要：[目的]提高红皮梨的果实品质。[方法]选用“金果”条黑袋在陕西省白水县和蒲城县对满天红梨进行套袋,研究不同摘袋时间对满天红梨果实外观品质、内在品质和贮藏品质的影响。[结果]摘袋时间越早,满天红梨的果锈指数、叶绿素含量越高,果实硬度越低。采收前25-35 d（8月上中旬）摘袋,果锈、日烧均严重,果实着色不良,果实硬度较低。采收前10-15 d（8月下旬）摘袋,果锈、日烧均较轻,果实着色良好,果实硬度较高,耐贮性良好。海拔较低的灌区要注意防止黑点病及裂果的发生,海拔较高、没有灌溉条件的塬区要注意防止日烧的发生。[结论]采收前10-15 d（8月下旬）是满天红梨最佳的摘袋时间。[Objective] The aim was to improve the fruit quality of red-skinned pear.[Method] The Mantianhong pears in Baishui Country and Pucheng Country of Shanxi Province were bagged with Jinguo black bags and the influences of different uncasing time on the appearance quality,internal quality and storage quality of Mantianhong pear fruit were studied.[Result] The fruit rust index and the chlorophyll content of Mantianhong pear were higher and the fruit firmness was lower when the uncasing time was earlier.The fruit rust and sunburn were all serious, the fruit had poor colouring and the fruit firmness was lower when the fruits were uncased at 25-35 d before harvest（early and middle August）.The fruit rust and sunburn were all light,the fruit had good colouring,the fruit firmness was higher and the storability was good when the fruits were uncased at 10-15 d before harvest（in later August）.It should pay attention to prevent the occurrence of black-dot disease and fruit cracking in the irrigation area with low altitude and the Yuan area with high altitude and without irrigation condition should pay attention to prevent the occurrence of sunburn.[Conclusion] 10-15 d before harvest（in later August） was the optimum uncasing time of Mantianhong pear.
