The present invention relates to a method for cultivating planted forest to high-yield pulpwood. Said method includes the following steps: cutting seed spicae of fast-growing forest according to the density of 2000-2600 plants of every mu; trimming newly-grown twigs; after the tress are grown up, alternate plant intermediate cutting; and then alternate row intermediate cutting, and finally completely cutting remained trees.
Description
Technical field
The present invention relates to a kind of forest production technology, specifically a kind of forest plantation pulpwood high yield technique.
Background technology
According to statistics, in the world in the paper-making industry of developed country, used raw-material be lumber fibre more than 95%, and in China's paper-making industry, because raw material supply is limited, the lumber fibre proportion is very little.In production of forestry in the past, employing be a field planting, finish the back at growth cycle and concentrate the production model of felling.This production model production cycle is long, can not in time satisfy the demand of market to paper making raw material.If adopt term growth, concentrate the production model of felling, then forest, growth in volume very little in the age of tree is in speed and gives birth to stage phase and just felled, and the growth potential of forest can not get bringing into play fully effectively, and this will cause volume of timber total yield to descend.If the method for wanting to adopt dense planting is to increase the output of forest, its purpose also is difficult to reach.Because in forest produces, follow the rule of " last output is certain ", promptly the output of different densities standing forest is very approaching.Planting density is excessive, and forest then breaks up the sparse density of regulating naturally.Therefore adopt the method for dense planting merely, can't reach the purpose of final increase pulpwood output.
Summary of the invention
Purpose of the present invention just provides a kind of forest plantation pulpwood high yield technique, in the output that guarantees the large diameter tree material, can in time obtain timber with small diameter as paper making raw material again, improves the total yield of the volume of timber thus.
The artificial woods pulpwood of the present invention high yield technique is achieved in that
A. press the kind fringe of the density cuttage fast-growing woods wood of every mu of 2000-2600 strain;
B. treat that it is behind the nursery stock more than 2 centimetres that kind of spike length becomes the diameter of a cross-section of a tree trunk 1.3 meters above the ground, whole stumps, and after the stump director goes out newborn twig, prune;
C. treat that it is behind the trees more than 3 centimetres, every the strain intermediate cutting that nursery stock grows up to the diameter of a cross-section of a tree trunk 1.3 meters above the ground; Treat trees long to the diameter of a cross-section of a tree trunk 1.3 meters above the ground be more than 6 centimetres after, the interlacing intermediate cutting; Trees long to the diameter of a cross-section of a tree trunk 1.3 meters above the ground be more than 9 centimetres after, every strain, interlacing intermediate cutting; Behind each intermediate cutting royal tree all being carried out branch prunes;
D. treat trees long be more than 12 centimetres the time to the diameter of a cross-section of a tree trunk 1.3 meters above the ground, the intermediate cutting forest, leave tree 70-90, grow to more than 21 centimetres until its diameter of a cross-section of a tree trunk 1.3 meters above the ground, all cut down down.
In the above-mentioned forest plantation pulpwood high yield technique, the newborn twig behind the nursery stock stump is pruned, and is to keep two twigs, wipes out unnecessary twig.
In the above-mentioned forest plantation pulpwood high yield technique, behind described each intermediate cutting the branch that royal tree carried out being pruned, is to select one to cut in thick branch, and the snag director prunes after going out newborn twig, keeps two twigs, wipes out unnecessary twig.
In the above-mentioned forest plantation pulpwood high yield technique, described fast-growing woods wood is fast growth poplar or phoenix tree.
Among the present invention, planting the fringe cuttage generally is to carry out in the spring in every year, the cutting density of every mu of 2000-2600 strain, and existing bigger planting density can guarantee the normal growth needs such as daylighting, ventilation and nutrition of nursery stock again.In the autumn then of growth, the diameter of a cross-section of a tree trunk 1.3 meters above the ground of nursery stock just can be grown 2-3 centimetre, and can carry out whole stumps this moment to the nursery stock that survives, and treats that the stump place grows the laggard row of newborn twig and prunes.
To 1 year autumn, the diameter of a cross-section of a tree trunk 1.3 meters above the ground of trunk just can be grown 3-4 centimetre, and the growth branch of stump after pruning be because remain with two at least, thus just need carry out every the strain intermediate cutting this moment, and the forest that keeps is carried out the branch pruning.Like this, both the continued growth for forest provided necessary space, had also obtained a certain amount of undersized log simultaneously, as the papermaking raw material.
To the 3rd year autumn, the diameter of a cross-section of a tree trunk 1.3 meters above the ground of forest trunk just can be grown 6-7cm, and tree looks higher, and the space that branch accounts for is bigger, thus just need carry out the interlacing intermediate cutting this moment, and the forest that keeps is carried out branch prune.Like this, can obtain more undersized log, the forest that stays can be accessed keep necessary space of normal growth and material conditions as the papermaking volume of timber.
To the 4th year autumn, the diameter of a cross-section of a tree trunk 1.3 meters above the ground of forest trunk just can be grown 9-10 centimetre, and from this period, forest enters speed and gives birth to the stage, no matter was the diameter of a cross-section of a tree trunk 1.3 meters above the ground of forest, highly therebetween, and the still shoot growth of forest growth all is in quick vegetative stage.Therefore, at the beginning of this stage begins, just need carry out intermediate cutting, promptly avoid influencing normal stand structure, meanwhile also obtain a lot of papermaking volumes of timber because of density is excessive with the bigger intensity of intermediate cutting to forest every strain, interlacing.
To the 5th year autumn, the diameter of a cross-section of a tree trunk 1.3 meters above the ground of forest trunk just can be grown 12-14cm, and forest is about to abundant closing.Carry out every the strain intermediate cutting this moment, with when obtaining many papermaking volumes of timber, makes the density of residue forest of reservation identical with traditional forestry planting density.To the 8th year autumn of normal growth end cycle, last forest all can be cut down, cut down the cycle thereby finish a wheel.
The growth rhythm of forest is: before the inabundant closing of standing forest, the output of standing forest rises with the increase of stand density.Forest plantation high yield technique of the present invention is formulated according to this rule, promptly in the initial planting rational close planting, then along with the growth of forest, by intermediate cutting year by year and to the mode of royal tree moderate pruning, the density of forest is reduced year by year, like this can a wheel cut down the cycle second and third, the results that the papermaking volume of timber all arranged in several years such as four, five, can guarantee not influence the normal growth of forest again, thereby cut down in the cycle at a wheel, the volume of timber total yield in the unit are is significantly increased.Key point of the present invention just is this.
