【摘要】 对华口16年生和二重山35年生细柄阿丁枫人工混交状态下生长过程的研究表明:由于树种组成、林分密度和树龄不同,两地细柄阿丁枫的生长过程有差异,但均表现出生长潜力大的特点。二重山由于长期受林分密度过大的影响,林木营养空间不足,长的细高,高径比失调,其胸径和材积连年、平均生长量小于华口,华口细柄阿丁枫早期速生特征明显。华口16年生和二重山35年生的细柄阿丁枫材积连年生长量与平均生长量尚未相交,说明具有培育大径材的潜力。更多还原

【Abstract】 The study on the growth processes of the mixed plantation of Altingia gacilipes in Huakou and Erchong hill indicated that the difference is significant between the two sites becanse of different tree composition,stand density and tree age.The trees in Erchong hill are thin and high and scarce of nutrition space due to too large density,so annual and mean growth of diameter and volume are lower than those in Huakou.Altingia gacilipes in Huakou shows the clear characteristic of fast growth during yong period.The annual and mean volume growth don’t intersect at the age of 16 and 35.This shows that Altingia gacilipes has the potentiality of being big diameter quality.更多还原
