杨树林分卫生间伐试验研究

Experimental Study of Poplar Stand for Sanitation Disafforestation

发生病虫害的杨树林分,通过卫生间伐,不仅能大大改善林地卫生状况,控制林分病虫害的重复发生和蔓延,而且通过卫生间伐能促进林木的生长,提高木材质量,缩短林木成熟期,能显著提高林木工艺价值和经济效益。

Sanitation disafforestation can improve the condition of poplar stand infected by pest and diseases and control the reoccuring and pervading of pest and diseases. Sanitation disafforestation can accelerate the growth of stand and improve the wood quality, and thus shorten the forest mature stage. It also can incease the techniques value and economic benefit.
