Embodiment Construction

[0010] The present invention will be further explained below in conjunction with specific examples.

[0011] For the cultivation method of Korean pine plantation, in terms of site conditions, Korean pine likes shady slopes on slopes, and the slope is preferably between 10 and 20cm. The initial planting density of the section with better site conditions is 4000 trees, and the site conditions are poor. , the density can be 3000 trees, the row spacing can be 2-3m, and the canopy density of the stand can reach about 0.8, and depending on whether the mixed broad-leaved tree species hinder the growth of Korean pine, the thinning intensity should be 20% of the number of trees, and the broad-leaved trees should be reserved. , determined by retaining about 0.4 canopy closure on the side of the Korean pine. In early May, use pine tar plus diesel oil 1:1, pine tar plus gasoline 1:1 or pine tar stock solution to dry the treatment. The first tending time of the year was in late May, and t...

Abstract

The invention discloses a method for cultivating a Korean pine planted forest. From the aspect of site conditions, in the slope direction aspect, Korean pines require shade slopes, and the gradient is preferably within 10-20cm, the initial planting density in districts with good site conditions can be 4000 Korean pines, the initial planting density in districts with poor site conditions can be 3000 Korean pines, the line spacing can be 2-3m, the canopy density can reach about 0.8 according to the forest, whether mingling broad-leaf species influence growth of the Korean pines or not is comprehensively considered, the intensity of intermediate cutting is 20% the number of the Korean pines, broadleaf trees are reserved, and it is determined by reserving about 0.4 canopy density on the side portions of the Korean pines. At the beginning of May, the mixture of pine tar and diesel oil with the ratio being 1:1, or the mixture of pine tar and gasoline with the ratio being 1:1 or pine tar raw liquid is used for conducting dry painting treatment. Mountainy nursery of the Korean pines can be achieved, and the history that seedling culture of the Korean pines can only be achieved in the flat ground is ended. Mountainy seedlings are high in yield and good in quality, and the cost of the mountainy seedlings is lower than the cost of flat ground seedlings.

Description

technical field [0001] The invention relates to a method for cultivating plants, in particular to a method for cultivating a Korean pine plantation. Background technique [0002] Korean pine is one of the precious timber tree species in my country. The artificial cultivation of Korean pine forests has far exceeded the distribution limit of natural forests. The growth of the artificial Korean pine forest is twice that of the natural forest, and the cultivation of the Korean pine plantation is of great significance. The planting of Korean pine seedlings for afforestation is done in autumn and spring in some places, and when they are often stored in winter, improper handling will affect the survival rate of afforestation. This is because Korean pine is an evergreen tree species, and its respiration and transpiration are stronger than those of deciduous tree species in winter. It is difficult to grasp the physiological requirements for overwintering storage after autumn. adju...
