摘　　要：为研究无纺布果袋内微环境的变化及其对库尔勒香梨果实品质的影响，采用HOBO WERE微型气象站及EI-USB-2[1]温湿度记录仪对不同颜色无纺布果袋内外的光照强度、温度和湿度进行实时监测，对不同颜色无纺布果袋内的果实品质进行了分析比较。结果表明：与外界环境相比，袋内光照强度明显降低。白天果袋内温度显著高于外界，夜间比外界略低，湿度呈现相反变化。三种颜色的果袋中，光照强度以白色果袋最高，黑色果袋最低。白色果袋内平均温度最高，湿度最低，蓝色袋内平均温度最低，湿度最高。在16：00～22：00时间段内，黑色果袋温度最高，湿度最低。套袋后单果质量、总糖及Vc含量平均降低了17.00%、8.24%和9.91%，果实硬度和总酸含量则平均提高了11.63%和3.53%。白色袋的单果质量和总糖均最高，蓝色袋的Vc含量最高。用白色和蓝色的果袋套袋可显著提高果面的光泽度，且采前去袋可有助于果实的着色。To study changes of microenvironment in non-woven fruit bag and its effects on fruit quality of Korla Fragrant Pear, by using HOBO WERE minimal weather station and EI-USB-2[1] temperature and humidity recorder, internal and external light intensity, temperature and humidity of different color non-woven bags were real-time monitored, and fruit qualities in different color non-woven bags were analyzed and compared. The results show that, compared with the external environment, internal light intensity of bag is decreased obviously. Internal temperature is signiifcantly higher than the outside at daytime, and slightly lower than outside at night, but the humidity change is opposite. Internal light intensity of white fruit bag is the highest, and that of black fruit bag is the lowest in three colors of fruit bags. White fruit bag has the highest internal temperature and the lowest humidity, and blue bag has the lowest internal temperature and the highest humidity. From 16：00 to 22：00, black fruit bag has the highest internal temperature and the lowest humidity. Average single fruit mass, total sugar content and Vc content in bagged fruits are decreased by 17.00%, 8.24%, 9.91%, and average fruit hardness and total acid content are increased by 11.63%and 3.53%. The white bag treatment has the highest single fruit mass and total sugar content, and the blue bag treatment has the highest Vc content. White and blue fruit bags can signiifcantly increase fruit surface gloss, and pick off bags before harvest can help fruit coloring.
