【摘要】 设计了以黑荆树与巨尾桉混交的３个模式、黑荆树纯林、巨尾桉纯林共５个处理进行试验。经过一个轮伐期６ａ的观测研究，结果表明以黑荆树４巨尾桉１的混交比例作株间混交的模式最为理想，６年生林分总蓄积量达７２．１ｍ３·ｈｍ－２，其中巨尾桉４６．１ｍ３·ｈｍ－２，黑荆树２６．０ｍ３·ｈｍ－２，投入产出比为１∶３．４。更多还原

【Abstract】 This paper designed 5 treatments of 3 models of Acacia mearnsii and Eucalyptus grandisE.urophylla mixture,A.mearnsii pure forest and E.grandisE.urophylla pure forest.Through the observational study of a 6year rotation,the results indicate that the model of the mixed proportion of A.mearnsii (4 trees) to E.grandisE.urophylla(1 tree)is the optimal;the total stocking of the 6yearold stand reaches 721m3/hm2,of which the stocking of E.grandisE.urophylla reaches 461m3/hm2 and that of A.mearnsii reaches 260m3/hm2;and the inputoutput ratio is1:34更多还原
