【摘要】 本文通过对椴树(Tilia amurensis Rupr.)落叶松(Larix olgensis Henry)混交林生长和种间关系研究,肯定了营造椴、落混交林是成功的,合理混交能促进椴树和落叶松生长。在林龄24年生时,椴、落混交比为1∶3和2∶3林分蓄积量略高于落叶松纯林;3∶3的则比落叶松纯林低8％。在三种混交比中,以2∶3椴树分叉率最低;3∶3椴树Ⅰ级木比例最大,且分布均匀。椴树10—24年生适宜庇阴度为1.3—1.6。初始间伐年龄为12 a,间伐间隔期以6—7 a为宜,更多还原

【Abstract】 This article assures that silviculture of Tilia amurensis and Larix olgensis mixed forest is successful, by the means of studying on the growth of these two tree species and their interspeeific relationship. Reasonable mixing can promote the growth of the two species. At 24 years old of the stand, the mixing ratio of Tilia amurensis and Larix olgensis is 1∶3 and 2∶3. The stand stocking volume is higher than that of pure stands of Larix olgensis. When the ratio is 3∶3, the stand stocking is 8％ lower than that. of pure staad of Larix olgensis. Among the three mixing ratios, 2∶3 is the lowest in branching, 3∶3 is the most one in the Ⅰ class ratio of Tilia amurensis and well-dist-ributed. The first thinning time is 12 years old, and the period is 6—7 years. The suitable shade tolerance is 1.3—1.6 for 10—24 years old, Tilia amurensis stand.更多还原
