Abstract: A study on the pattern ofmicroenvironmental changes of bagged fruits is beneficial to optimizing bagging techniques. In the present experiment, the effect of bagging techniques on the fruitmicroenvironments inside the bags was examined by using advanced apparatus to monitor both temperature and relative humidity. The results indicated that, bagging techniques and external environmental factors could affect fruit surface temperatures and its microenvironment to different extents. Moreover, there existed a significant difference in temperatures between bagged and exposed fruits at different timeswhen bags were removed in a day. In addition, a certain effect of differentmethods of disclosing bagswas found on fruit surface temperatures and separate removal of bags seemed to be more favorable to light acclimation.
