Research on Transformation Technology of Low Efficiency Forest of Yunnan Pine
In forestry planting engineering,the transformation of inefficient forests can improve the growth rate and wood quality of trees,and increase economic benefits.Yunnan pine is an important afforestation tree species in southwestern China,with high ecologi-cal,economic,and cultural value.However,due to poor management and variety degradation,some areas of Yunnan pine have en-countered problems such as slow growth and low biomass,becoming inefficient forests.In order to improve the ecological and economic benefits of Yunnan pine stands,it is particularly important to carry out research on low efficiency forest transformation technologies.The article analyzes the reasons that led to Yunnan pine becoming an inefficient forest,and provides a detailed introduction to the transfor-mation technology of inefficient forests from several aspects such as breeding of improved varieties,thinning,replanting,and afforesta-tion under the canopy.
