杉木不同初植密度和经营方法对林分生长及效益的影响试验

Discussion on the Planting Technique of Cunninghamia lanceolata

杉木是我国重要速生用材树种,也是川南优质乡土树种。本文针对杉木的生物学、生态学特性,以及通过其不同初植密度和经营方法对林分生长及效益的对比实验和分析,提出杉木在川南的合理初植密度和新的栽培方法,进行推广应用以进一步提高其生态效益和经济价值。

Cunninghamia lanceolata is one of important rapid-growth tree species in China,and its ecological and economic values are high in many regions.It also is a high-quality native tree species in South Sichuan.In this paper,a reasonable initial planting density and new cultivation methods in southern Sichuan are proposed according to biological and ecological characteristics of Cunninghamia lanceolata,and the comparative experiments are made on stand growth and efficiency through its different initial-planting densities and operating methods for the purpose of promoting the use of Cunninghamia lanceolata to further enhance its ecological and economic values.
