Technical Measures and Benefit Analysis of Low-efficiency Forest Renovation of Oil Tea in Luodian County
This paper analyzed the technical measures for the reconstruction of low-efficiency forest of oil tea in Luodian County,sum-marized the social and economic benefits,and provided theoretical support for the reconstruction of low-efficiency forest of oil tea.In this study,low-efficiency forest of oil tea in Luodian County was selected as the sample plot,and three groups were set up according to the differences of low-efficiency forest transformation techniques,namely,T1 group for soil management+water and fertilizer manage-ment,T2 group for soil management+water and fertilizer management+stand structure optimization,and T3 group Soil management+water and fertilizer management+stand structure optimization+improved seed transformation,analyze the contents of different trans-formation technical measures,and summarize the overall benefits.The results showed that the average fruit weight and average plant yield of T3 group were higher than those of the other two groups(P<0.05),followed by T2 group,and the overall trend was T3>T2>T1.The tree height,crown width and ground diameter in T3 group were higher than those in T1 and T2 groups(P<0.05),and the in-dexes in T2 group were better than those in T1 group(P<0.05).The fruit height,fruit diameter and fruit volume in T3 group were higher than those in T1 and T2 groups(P<0.05),but there was no significant difference in fruit index between T3 group and T2 group(P>0.05).The fruit indexes of T2 group were better than those of T1 group(P<0.05).The fresh seed rate,dry seed oil content and fresh fruit oil content in T3 group were significantly higher than those in the other two groups(P<0.05).Therefore,it is concluded that soil management+water and fertilizer management+stand structure optimization+improved seed transformation has the best and obvious effect in the transformation of low-efficiency forest of oil tea in Luodian County.After the transformation,the income of low-ef-ficiency forest can be improved.Comprehensive evaluation and analysis prove that T3 group treatment has the best effect and can pro-mote the economic development of the region.
