摘  要:
采用固定标准地定位观测法,对天然杨桦林在相同林分类型、相同抚育间伐强度、相同林冠下更新树种的林分固定标准地进行松土、除草、施肥。结果表明:天然杨桦林林地施肥集约经营的效果显著,标准地公顷蓄积增长量和增长率都明显高于对照,其增高值分别为公顷蓄积增长量8.6:7.1为121.13%和增长率8.1:6.4为126.13%;林地集约经营对更新苗木也是受益的。

摘  要:
Soil loosing,weeding and fertilization were done to the fixed standard fields of natural poplar and birch forests with same stand type,tending thinning strength and pre-regeneration species by means of location observation.The results showed that the effect of fertilization and intensive management on natural poplar and birch forests was significant,The storage increment and the growth rate per hectare were both higher than the contrast obviously,the increased value were 121.13%(8.6:7.1) and 126.13%(8.1:6.4);the intensive management was also benefit to the pre-regeneration seedlings.
