摘　　要：观测并分析了套袋鸭梨果实发育过程中及1d中的袋内与树冠内的温度和相对湿度变化。结果表明：袋内温度和相对湿度分别较树冠内平均高0．45℃和8．4％，温湿度系数高0．37；1d中袋内温湿度分别有16h和10～14h高于树冠内。The temperature and humidity of inner fruit bag and crown was measured and analysed daily along the development course of bagged Yali pear fruit. The result shows ： the temperature and RH in the bag is separately 0. 45 ℃ and 8.4% higher than the average of crown, the temperature and humidity coetfficient is higher more than 0. 37, the inner bag temperature has 16 h and the RH has 10 - 14 h higher than in the crown daily.
