摘　　要：通过以营造子代试验林的方式对1996年营建于云南省蒙自县芷村林场杨柳井和杨梅坝两林区的2片华山松母树林子代的林木生长效益进行了测定,并把用昌宁、腾冲、保山等华山松种源区以及弥勒华山松种源地(对照)的种子营建的华山松子代林一并纳入试验,根据其10年生时的观测材料作统计分析。芷村林场两华山松母树林的子代林每公顷的林木材积生长量比对照提高了2.04%～7.13%。但在参试的7个处理中,表现较好的为昌宁、腾冲华山松种源区,其华山松子代林每公顷的林木材积超过了对照的32.48%～35.64%,比芷村林场2个华山松母树林的子代林提高了23.67%～32.93%。The growth benefits of progeny of Pinus armandi seed production stand in Zhicun forest farm of Mengzi County in Yunnan Province were analyzed and appraised.Besides the local provenances,10 years old progeny forests including provenances of Changning,Tengchong and Baoshan were taken as experimental materials.The Pinus armandi stand in Mile County was chosen as the control.The analysis results showed that the volume growth increments of studied progeny forests were 2.04%-7.13% higher than the control.Among the tested 7 provenances,two provenances namely Changning and Tengchong had good performance,with the unit area volume 32.48%-35.64% higher than the control,and 23.67%-32.93% higher than the local provenances in Zhicun forest farm.
