Method for improving quality of poles of artificial young phoebe bournei forest with three-step method

Abstract

The invention discloses a method for improving the quality of poles of an artificial young phoebe bournei forest with a three-step method. The method comprises the following steps: (1) selecting a sheltering valley land with the altitude of less than 400 m, reserving robust and long-life fallen broad-leaf wood with the height of more than 15 m, keeping the canopy density to be 0.2-0.3, and constructing an afforestation land suitable for growing of the young forest by upper-layer shielding; (2) establishing a young forest group establishment period through measures of soil preparation, afforestation, tending, fertilization, pest control and the like; and (3) selecting dominant wood in the closed forest, carrying out management in the pole growth period, such as release cutting and tending and dominant wood cultivation. The growth internal environment of poles is created, the forest land conditions and the forest stand structure are improved, the preservation rate of young forest is increased, the branching rate of main shoots is reduced, the growth of the poles is promoted, the quality of the dominant wood poles is remarkably improved, and the method has a wide application prospect in the creation of precious tree species timber forests and cultivation of large-diameter trees in the north-central region of Zhejiang Province.

Description

technical field [0001] The invention belongs to the technical field of forestry, and in particular relates to a three-step method for improving the quality of pole materials of Nannan plantation young forests. Background technique [0002] Fujian Nan ( Phoebe bournei ) is an evergreen tree of the genus Phoebe in the family Lauraceae. It is a national second-level key protected plant and a unique tree species in China. It has a straight trunk, fine structure, smooth cut surface, beautiful texture, soft texture, and delicate fragrance. It is a unique high-grade economic timber tree species in my country and has always been a precious material for the imperial court. Due to its wide range of uses and high economic value, its wild resources have been severely damaged, and natural forest resources are almost exhausted. Therefore, while protecting its natural forest resources, it is of great significance to extensively carry out forest cultivation after the expansion of Nannan a...
