文章用标准地对比分析方法研究了相同年龄不同立地条件不同混交类型紫椴人工幼林生长的特点。结果表明:紫椴人工林坡上和坡下生长较差,在山中部立地条件下生长较好,在坡度为6~25°范围内对紫椴幼林生长影响不明显;土壤A层厚与幼林生长有密切关系;在三个混交类型中落椴混交比红椴混交和云椴混交效果好。在造林时选择适宜的立地条件和混交类型对紫椴幼林生长是非常重要的。
In this paper, the characteristics of growth of Tilia amurensis plantations with different mixed-stands of the same age and different site conditions were studied by standard comparative analysis. The results showed that: Tilia amurensis plantation grew poorly on the slope and on the slope, and grew well on the site of the mountain central part, but had no obvious effect on the growth of young plantation of Tilia amurensis at a slope of 6 ~ 25 °. Growth is closely related to the three mixed types of linden mixed better than the mixed linden and linden. It is very important to select the suitable site conditions and the type of mixed plantation for the growth of young Tilia.
