摘　　要：以砀山酥梨为试材,通过对不同套袋处理果实生长体积的测定,研究了果实的生长曲线与生长速度。结果表明:不同套袋处理并不能改变果实的生长曲线,各处理果实的生长曲线依然为双S曲线,但相同测量时间段内果实体积的增加量不同,即不同处理果实生长速度不同。套塑膜袋果实生长速度最快,平均每15 d果实体积增加量为40.9 ml;套3层纸袋果实生长速度最慢,平均每15 d果实体积增加量为31.6 ml;双层袋略高于3层袋;单层袋与对照(CK)相当。Fruit growth curve and growth speed of Dangshan pear were studied by the mensuration of fruit volume under different bagging methods. Results showed that different bagging methods did not change fruit growth curve （still double S curve）. But fruit volume increased differently during the same survey time,which means to say that different bagging methods changed fruit growth speed. Fruits bagged in plastic film bag had the fastest growth and the volume increased by 40,9 ml per 15 days on average. Fruits hagged in three-layer paper bag grew most slowly and the volume increases by 31.6 ml per 15 days on average. Growth of fruits bagged in double-layer paper bag increased a little more than those in three-layer bag and the speed of fruits bagged in single-paper bag increased by the same level as those without bagging.
