Problems solved by technology

However, due to its narrow natural distribution, limited to Zhejiang, Fujian, Jiangxi and southern Anhui, few people know about its excellent quality characteristics
In addition, Zhejiang Phoebe has high requirements on light, soil, water and nutrient conditions, and the mother forest of Zhejiang Phoebe is scarce, the provenance is scarce, and the growth is slow, which seriously restricts the development and utili

Embodiment Construction

[0027] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0028] The implementation site is located in subclasses 16 and 32 of Tiantong Forest District, Tiantong Forest Farm, Yinzhou District, Ningbo City, Zhejiang Province; the experiment period is from January 2002 to December 2014.

[0029] The area of ​​Tiantong forest area is 370hm -2 , with an altitude of 80-653.3m, and a large area of ​​typical mature evergreen broad-leaved forests are distributed in the territory. In the natural forests in the valleys, Phoebe zhejiang often accompanies the subforest layers of Sour jujube, Liquidambar, and Phoebe chinensis communities, but the distribution Fewer in number and slower to grow. Therefore, we identified Zhejiang Phoebe as a precious tree species for afforestation in the ecological restoration of the valley area;

[0030] In the Tiantong forest area, the logging sites with slopes from south...

Abstract

The invention discloses a phoebe chekiangensis young growth cultivation method. More healthy and strong super individual trees are produced for phoebe chekiangensis according to the density effect of colonization forest stand, the self-thinning effect and the relation between the number of the super trees and the stand volume. By means of planting site selecting, planting, cultivating, super tree selecting, interference tree intermediate cutting, pole stock quality improving, reasonable light, water, fertilizer and soil managing and other regulating technologies, the tree trunks of the phoebe chekiangensis become straight from top to bottom and full, the advantages of top ends are obvious, and the pole stock quality efficiency is obviously improved. The method has the technical advantages that the number of the super individual trees is large, the phoebe chekiangensis is healthy and strong, the pole stock quality is good, the forest stand volume is high, productive potential is high, the effect is obvious, and the method can be applied and popularized in production and can also be applied to improve the pole stock quality of young trees of other precious commercial tree species.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a cultivation method of Zhejiang Phoebe juvenile forest. Background technique [0002] Phoebe chekiangensis (Phoebe chekiangensis) is a tall evergreen tree of the genus Phoebe in Lauraceae, and is a famous rare and endangered tree species in southern my country. Zhejiang Nan is a well-known precious timber tree species. Its trunk is straight, its crown is neat, its wood is hard and dense, not warped or cracked, not easy to decay, its beveled surface is smooth and beautiful, fragrant and shiny. The good material of the mold is a treasure among woods in the international market. Planting Zhejiang Nan can earn foreign exchange through export and increase economic income. Therefore, vast hills and mountainous areas can be used as precious timber tree seedlings for afforestation. Due to its strong shade tolerance, Phoebe zhejiang can be mixed with other positi...
