Thinning Effects And Technologies Of Mixed Forest Of Artificial KoreanPine And Natural Regenerated Deciduous Broadleaved Trees In Liaodong Region

The Thinning effects and technologies were studied on the mixed forest of planted Pinus koraiensis and broadleaf trees in Liaodong region for 5 years. The results are as follows: the growth of residual trees significantly promoted, the death amount reduced, the stand volume increment increased, the forking rate of Pinus koraiensis decreased, the stand soil and vegetation ameliorated, and a certain thinning income acquired. A simple systemic thinning technology adequate for the mixed forest of planted Pinus koraiensis and broadleaf trees in Liaodong region were carried, conducting the forestry management and production.
