Embodiment 1

[0113] In 1999, a 39-year-old Chinese fir plantation with an area of ​​20 mu in Jishan Work Zone, Gekeng State-owned Forest Farm, Dehua, Fujian Province, conducted a selective felling experiment with 28-40 plants / 667m2 of high-growth value-added dominant trees. In 1999, the average DBH was 21.7 cm, and the maximum DBH was 38 cm. The three-diameter group (DBH 30-39 cm) accounted for 7.86% of dominant trees; the largest DBH in 2013 survey was 53 cm, and the largest DBH in the survey at the end of 2018 was 59.7 cm. 35 cm, the proportion of dominant trees above the three-diameter group rose to 43.14%, and there were 21 trees with a DBH above 45 cm; the volume per unit area of ​​large trees increased from 143.91 m3 / hm2 to 261.81 m3 / hm2. This proves that: Chinese fir still has at least 30 years of growth advantage in late DBH after entering the mature age.

Embodiment 2

[0115] In 2013, the area of ​​09 and 03 sub-classes in the pit mouth area of ​​the field was 94 mu, which was the fir clearcutting land, and the land type was Class Ⅲ land. The afforestation experiment of cultivating high-value permanent forest was carried out. For tree planting, the above-mentioned (1) tree species with good wood material properties, large uses, high value and good market prospects, (2) tree species with rich nutrient content in leaves, fallen leaves and rotten soil for fertilizing, (3) fast-growing and high-yielding tree species, (4) ) Tree species that can naturally plant self-renewal and self-development, (5) Tree species that have large seeds, starch-containing protein, etc. High-value permanent forests are created through the combination of multiple types of tree species, such as , red cone, oak, sweetgum, bald fir, mandarin wood, and firewood. According to the survey in 2018, the humus-infiltrated layer on the surface of the soil has changed to light da...

Embodiment 3

[0119] The small class cultivated is located in the 07 forest class, the 06 large class, and the 03 small class in Yingshan Village, Longxun Town, Dehua County, Fujian Province, with an area of ​​35 mu. The average temperature is 17.5°C, the lowest temperature is -5°C, and the average annual precipitation is 1673.9 mm. It belongs to the subtropical and mid-subtropical transitional climate zone. The small class planted forests in 1981; the site is humus-free or humus-penetrating light brown middle layer 3 types of land, stand diameter value-added grade B or above, and high economic, ecological and social landscape values. The cultivation techniques of permanent forests are as follows:

[0120] According to the field investigation, the forest condition of the small class site is the third type of land with poor site, and the artificial plantation of Chinese fir seedlings originates from the pure forest of Chinese fir. The forest land is beside the road, and it belongs to the ac...

Abstract

Disclosed is a high-value permanent forest cultivation technology with functions of land utilization and land maintenance. According to the technology, the design and setting of 3 or more tree species of 6 types of various matching trees which contain soil fertility, can naturally improve fertility and are suitable for sites are adopted, and advanced breeding achievements and forest culture and management technologies are utilized for new technology survey design of land utilization and land maintenance, diameter-containing groups and other new indexes; existing forests are subjected to selective cutting; the tree species of 6 types are classified, selected and set; soil preparation for afforestation or interplanting is conducted; tending management is conducted; target trees are classified; thinning is conducted; regeneration under a selection system is conducted, and cultivated forests have forest sustained-yield management natural capabilities like natural forest land fertility improvement, natural seeding self-renewal development, rich biodiversity, and resistance to diseases, insect pests and natural disasters. With every 10-20 years as one management period, permanent forests are formed, wherein the permanent forests continuously have large-diameter timber precious and high-value output, crown canopies of mixed, uneven-aged, multi-layer and multi-tree-species towering trees permanently cover forest land, and the permanent forests have high economic, ecological, socioculture and landscape value. The problems that large-area abies holophylla pure forests in the southern regions have declined soil fertility and lower productivity are solved.

Description

technical field [0001] The invention relates to a forest cultivation technology, in particular to a cultivation technology of a high-value permanent forest which is more capable of cultivating the land. Background technique [0002] In the decades of forest management from the 1950s to the present, based on the stage of national economic development and the demand for timber at that time, the lack of forests is an opposition composed of forests, trees, soil, ecological benefits, economic benefits, and the environment. The unified forestry theory that conforms to the law of natural development follows the practice of forestry during the farming rotation period. Although there are proposals for suitable trees in suitable places, they are only suitable for suitable places and trees for individual tree species. They have not realized how to ensure the most basic growth of forest trees. The most important condition is the soil. "The use of land requires more cultivation of the la...
