本省以杉木为主的用材林基地建设取得了很大成绩,但也出现不少低产林分。营造针阔叶树种混交林已被人们所关注,但对杉木与其它一些针叶树混交,一般都认为不值得提倡。因为枯枝落叶分解后会使土壤酸化,这是一个弊端。但实践证明,也有一些杉木与柳杉、金钱松、马尾松、黑松、黄山松、湿地松、柏木等树种混交成功的实例。为给本省用材林基地建设提供混交林营造技术和经验。在省林业厅的支持下,我们于 Great achievements have been made in the construction of the timber-based timber forest base in the province, but many low-yielding forest stands have also emerged. The coniferous and broad-leaved mixed forest has become the focus of attention, but it is generally not considered to be worthwhile to promote the coniferous forest with other conifers. It is a drawback because the litter will decompose the soil after acidification. However, practice has proved that there are some succulent and Cryptomeria fortunei, Pinus massoniana, Pinus sylvestris, Pinus thunbergii, Pinus armandi, Pinus elliottii, cedar and other tree species mixed success example. To provide the province with the construction of timber forest to provide mixed forest to create technology and experience. With the support of the Provincial Forestry Department, we are here
