Abstract

The invention discloses a betula alnoides forestation method, and belongs to the technical field of forestation. The betula alnoides forestation method specifically comprises the following steps: selecting forestation land, chopping weeds and performing slash burning, performing soil preparation, transplanting, and performing tending management. The betula alnoides forestation method is used for effectively solving the problem that artificial betula alnoides forestation is not high in survival rate and trees grow slowly. The betula alnoides forestation method has the beneficial effects that the slash burning and strip-channel soil preparation are adopted, so that fast-acting nutrients are greatly increased, the soil fertility is improved, harmful animals are expelled, plant diseases and insect pests are reduced, the forest land sanitary conditions are improved, the deep-layer structure of soil is improved, the water permeability, the gas permeability and the water-retaining fertilization storage capacity are improved, the activities of microorganisms are promoted, the soil fertility is improved, the root development and the rapid overground part growth of betula alnoides are facilitated, and the cultivation survival rate is 95% and above. Moreover, after being transplanted, tree seedlings quickly grow, and the 3-year-old betula alnoides is 3.8m high at general, so that the betula alnoides forestation can be developed in large area, the condition that existing betula alnoides resources are in shortage can be changed, industrialization is formed, and good ecological benefits and economic benefits are obtained.

Description

A kind of Birch method of forestation

Technical field

The present invention relates to field of forest cultivation technology, be specifically related to the method for a kind of Birch cultivation afforestation technology, belong to afforestation technology field.

Background technology

Birch (Classification system: Betula alnoides Buch.-Ham. ex D. Don) belongs to Angiospermae, Dicotyledoneae, Fagales, Betulaceae, Betula, be a Precious Timber Species of China torrid zone, South Subtropical Area of China, be distributed in province (district) and the Nepal such as the Sichuan of China, Guangxi, Yunnan.

Birch timber do not stick up do not split, ratio of tangential to radial shrinkage is little, not yielding and decorative pattern and color and luster attractive in appearance, belong to medium-to-high grade timber, except the purposes such as antique traditional furniture, building and military project, general as plywood, top-grade furniture, timber floor and indoor decoration material, its resonance is functional, also being excellent fiddle butt, is the desirable seeds that China develops medium-to-high grade wood producing.

Because Birch wood usage is wide, economic worth is high, and material valency rises steadily, reached more than 3000 yuan/cubic metre at present, because Birch existing resource is little, the age of blossoming and bearing fruit is late again, in addition seed longevity is short, is multiplied into tree very difficult, must develops artificial afforestration technology by natural germination.Can people carry out Birch afforestation to there is survival rate not high now, generally below 60%, and sapling transplant after poor growth, 3 years are also long less than 3 meters, are difficult to grow into forest.

Summary of the invention

goal of the invention: the object of the invention is for problems of the prior art, a kind of Birch artificial afforestration method is provided.

technical scheme: Birch method of forestation of the present invention, specifically comprises the following steps:

1, plantation measures: select height above sea level 600 ~ 1000 meters, hidding and sunny side, soil layer is deep, quality is loosened, and is rich in organic matter, acid reaction, moistening and well-drained mountain depression hillside fields;

2, grass refining mountain is cut: after choosing planting site, ground weeds shrub is cut down and dries by 9 ~ October from lower to upper, then holds fire line successfully in forest land surrounding, selects calm cloudy day or morning, the mountain of igniting refining from outside to inside from top to down, limb remaining behind refining mountain, toothed burclover, butt will concentrate bunch to burnout;

3, wholely: planting site adopts ditch band method of soil preparation, namely from bottom to top along the soil digging of hillside horizontal direction trench digging, show native cubsoil separately, build up the low bank of earth between fields at the descending cubsoil of ditch, upward slope is shown mamoty after ditch is held successfully and fill in ditch, fill into ridge shape, Article 2 trench is dug again by afforestation line-spacing 1.8 ~ 2 meters, furrow width 60 ~ 70 centimetres, then digs 50 × 50 × 40 ㎝ planting holes by 1.5 ~ 1.8 meters of spacing in the rows in ditch by dark 50 centimetres;

4, transplant: annual late March, to early April, is selected fine day after cloudy day or rain, transplanted, height of seedling 20 more than ㎝ with one year seedling, want righting nursery stock, dark 2 ~ 4 ㎝ in depth ratio primitive root border place when planting seedling, earthing is careful, compaction in layers, face, cave is covered and is loosened the soil, and is above the ground level, and becomes turtleback shape, prevents ponding;

5, tending management: afforest and carry out weeding bushing autumn then and foster once, removes weeds in cave, digs and expand cave around cave, Second Year is respectively fostered once in spring and autumn respectively, foster at every turn and want comprehensive weeding, loosen the soil, the training root and stem of certain plants, weeding in summer in 3rd year, cut assorted, the table earth culture root and stem of certain plants, weeding in autumn, cut assorted, within the 4th year, carry out every year cutting weeds 1 ~ 2 time later.

beneficial effect: compared with prior art, its beneficial effect is in the present invention:

Birch method of forestation disclosed by the invention, adopt refining mountain and ditch band method of soil preparation, refining mountain can roll up quick-acting nutrient, increase soil fertility, and be conducive to driving away noxious animal, reduce damage by disease and insect, improve forest land sanitary condition, and the whole ground of ditch band can change clay fertilizer soil of filling in a form, add chiselling layer, improve the deep structure of soil, add highly permeable venting capability and water conservation stores fertile ability, promote microbial activities, thus improve the fertility of soil, the root system development and the acrial part that are conducive to Birch grow fast, therefore survival rate reaches more than 95%, and sapling transplants rear growth rapidly, Betula alnoides seedlings grow to 3 years raw time, set equal height and reach 3.8 meters, can afforest by large area development Birch by this method, alleviate the rare situation of Birch existing resource, form industrialization, the ecological benefits obtained and economic benefit.
