Description
Technical field
The present invention relates to forest technical fields, foster more particularly to the afforestation of a kind of raising Betula dahurica material and volume recovery
Method.
Background technique
Timber is the important source material in the development of the national economy as a kind of natural high molecular material.To improve ecological ring
Border is the main body of forestry development, to increase the forest reserves as the basis of forest development, using developing industry as forestry development
Emphasis, developing industry raw material fast-growing, high-yield woods make Forestry Industrial Structures from Forest Cultivation and the one-sided economy mesh of wood producing
Mark turns to the developing goal of more utilizations of resources of forest, so that resource is industrial with the utilization of resources and deposits common prosperity, is advantageously implemented woods
Industry ordering, scale, industrialization benign production, play bigger ecological benefits and economic benefit.
Cycle industrial material forest is that particular industry department provides raw material, reaches one by the way of directive breeding and intensive farming
Surely material standard is used, a part of commercial timber forest is belonged to.The development of China's cycle industrial material forest starts from fast-growing, high-yield woods, current industrial
The directive breeding of raw material forest conducts a research mainly around orientation, fast-growing, high yield, high-quality, stable and efficient 6 aspects, using quotient
Product and industrialized theory shorten the forest culture and management period using the science and technology and management measure of intensive farming, improve forest land production
Efficiency produces the wood raw material for meeting final use requirement out in enormous quantities.Directive breeding cycle industrial material forest efficiently uses limited
Forest land and resource environment advantageously form the rationalization structure and stands compositions cloth of timber.
A kind of method of forestation for improving wood of Cunninghamia lanceolata material is disclosed in patent CN108040804A, wherein being by China fir
One or more of tree species and masson pine, Phoebe bournei, red beech, Liriodendron chinense and Schima superba carry out mixing friendship or in the ranks mixed friendship, aggravation between strain
The competition of China fir and other tree species, and the broad-leaveds such as Phoebe bournei, red beech, Liriodendron chinense and Schima superba be easy to rot to be formed compared with China fir needle it is rotten
Matter is grown, the material of wood of Cunninghamia lanceolata is improved.
Betula dahurica is distributed in China North China and the Northeast, is born in the mountainous region primary forest periphery of 700~900m of height above sea level or so
In the secondary forest region hillside Di Shan, the drier place of mountain bamboo trunk or shaw.Distributed area sunshine total amount is larger, and reflectivity is low, absorptivity
Height is easy to appear high temperature, causes water evaporation quantity big, leads to soil drought, and soil fertility is lower, and humus content is few.Therefore,
The decline of Betula dahurica their location soil productivity, habitat deteriorate, and standing forest stability and productivity of forest stand are gradually reduced, and eventually lead to spine
Skin birch material is poor, and volume recovery reduces.Currently, there is not yet the method for improving Betula dahurica Wood Properties Within and volume recovery.
Summary of the invention
The object of the present invention is to provide a kind of afforestation Tending methods for improving Betula dahurica material and volume recovery, are by 2-
