皖南丘岗地区火炬松人工林伴生树种的选择与配置

Selection and allocation of associated tree species for Loblolly pine plantation in hillock areas of Southern Anhui Province

简要介绍了试验林地的概况,选择了25个树种进行试验,并按各树种林分平均胸径、平均树高、平均单株材积和平均单位面积蓄积的年平均生长量进行排序。对主要伴生树种的生长发育过程作了说明,指出伴生树种选择应遵循的原则以及混交形式,同时提出把建立林道和营造生态防火林带相结合。为皖南丘岗地区火炬松人工林提出可供选择的主要伴生树种。

This paper gives a survey on experimental forestland. 25 tree species were selected, and arranged in order by average diameter at breast height, average height, average individual volume and annual average volume increment in a unit area in this experiment. The paper expounds the growth process of main associated tree species, suggests the principle for choosing associated tree species and their mixed form, and for building forest roads with constructing ecological fire prevention belts. Main associated tree species are listed for Loblolly pine plantation in hillock areas of Southern Anhui Province.
