Thinning Effects on the Survival of Interplanting Trees Under Pinus massoniana Plantation

Abstract

Abstract:

Two kinds of artificial replanting broadleaved tree specieswere used as the research objects to study the survival of replanting tree species under Pinus massoniana plantation after four thinning intensities (T0:0%,T1:25%,T2:45%,T3:65%),which had been monitored for 11 years. The results showed that the survival rate of Schima superba was the highest under moderate thinning,and the survival rate of Erythrophleumfordii was the highest under light thinning in the early growth stage,and then the survival rate would be the highest under moderate thinning after forest formation. In general,the survival rates of the two interplanting tree species were the highest under moderate thinning. Erythrophleumfordii was more suitable for survival under non-thinning and light thinning than Schima superba. Schima superba was more adaptable to the environment under heavy thinning than Erythrophleumfordii,and moderate thinning can create conditions suitable for the co-growth of Schima superba and Erythrophleumfordii. The survival rates of the two interplanting broadleaved tree species were significantly different under different thinning intensities (P<0.05),which started to appear in the second year after planting. The survival of different broadleaved trees will vary due to changes in environmental conditions and the characteristics of their own tree species. Therefore,in pure forest mixed transformation,moderate thinning (45%) can improve the survival rate of interplanting trees.

Key words: pure plantations, thinning effects, mixed transformation, interplanting broadleaved tree, survival rate
