Description
Technical field
The present invention relates to a kind of afforestation method of beech tree cuttage seedling.
Background technology
The Ulmaceae Zelkova (
Zelkova) plant is one of precious hard broad-leaved commerical tree species of China.China is Zeldova natural distribution center, have zelkova schneideriana ((
Z.schneideriana), water elm (
Z.serrata) and large fruit beech (
Z.sinica) 3 kinds; 2 kinds of Guizhou natural distribution zelkova schneideriana and water elms, wherein the distribution of zelkova schneideriana is wider.The low beech tree nature that causes of the difficulty of collecting seed and seed nature germination rate upgrades difficulty, and artificial crushing the felling, therefore its wild resource is day by day rare, has been listed in national secondary and has laid special stress on protecting plant in addition.Along with beech trees is developed to going deep into of research, find that the beech tree has the moistening lung of being used as medicine of medical value preferably, schneider zelkova bark, can treat headache, heat is malicious; Leaf is used as medicine can be comfortable; Fresh bark is smashed external application to pieces can treat fire wound, rotten sore; Ethanol extract can have certain inhibitory action to the tyrosinase activity that plays key effect in the melanic biosynthetic process of human body.The beech tree can survive and the energy continued growth in the serious pollution situation; The beech tree has extremely strong resistance and detergent power to chlorine Cl and fluorine F pernicious gas, to arsenic As, and mercury Hg, plumbous Pb, cadmium Cd and chromium Cr have stronger absorption cleaning ability; The beech tree is a good green tree species that atmospheric pollution is had to resistance and detergent power, can select to improve and beautify ecotope as the plant of environmental pollution district and urban afforestation.
The existing preliminary research of beech tree seedling forestation technology.Most of research thinks that the best planting season of beech seedling is the 2-3 month after the beginning of spring; The best initial density in planting of treelet is 2m * 2m or 2m * 3m; Land occupation condition has larger impact to the growth of beech tree, the ground class that land occupation condition is good, and the growth of beech tree is very fast, the growth of the most applicable beech tree of sandy loam.The research of base fertilizer processing aspect has no report.The research of relevant beech tree cuttage seedling afforestation technology has no report.
Beech tree seedling breeding difficulty is this good bottleneck problem with aptitude source large-scale cultivation of restriction always.Breakthrough along with beech tree cuttage raise seedling technique, make beech tree cuttage seedling large-scale cultivation commodity timber forest become possibility.There are a large amount of secondary forest lands, weeds hillside fields and Cai Hou slash, mine in China, and because soil layer is thinner, chad content is high, and land occupation condition badly is in the state of letting a piece of farmland go to waste.After adopting this method to carry out afforestation, these land resourcess of letting a piece of farmland go to waste are utilized effectively, and beech cuttage seeding well developed root system, the ecological benefits preferably such as water and soil conservation, soil melioration, environment purification had.
Summary of the invention
The present invention mainly solves the technical problem that the barren hillside land beech cuttage seeding scale afforestation of letting a piece of farmland go to waste is utilized.
Technical scheme of the present invention:A kind of afforestation method of beech tree cuttage seedling comprises following steps: (1) method of soil preparation: in 8～September, more than after the barren hillside land of afforesting extirpates weeds, ploughing deeply 50cm, flatten into the tableland of wide 1.5m～2.0m; According to line-spacing 1.5m * spacing in the rows 1.0m, dig kind of a plant hole; The cave size is: long 50cm, wide 50cm and dark 40cm, product word arrangement;
(2) base fertilizer application process: before nursery stock transplanting, first apply fertilizer to the subsoil, the 1kg that often the spreads manuer in holes humus soil+0.25kg composite fertilizer of filling a prescription, earthing 5cm;
(3) cuttage seeding transplanting method: in October～November, the biennial cuttage seeding of just having fallen leaves is taken out from seedbed, only stay 1 trunk of high 20cm after most of branch is cut, use 20mg.L
-1GGR root-growing agent aqueous solution soaking 12 hours, the field planting of going up a hill, the trunk 5cm that bassets, irrigate normal root water.
Humus soil, perlite and pine tag that the formula humus soil is 1:1:1 by volume ratio form.
Described composite fertilizer is that the N:P:K mass content is the composite fertilizer of 15%:15%:15%.
The beneficial effect that the present invention reaches:
1) after adopting the whole ground of the method, can meet beech root growth needs ventilative, the permeable demand of loosening, make the enlarged areas of Root Distribution, be conducive to the growth of acrial part.After treelet was adopted to high-density planting, 1-2 branch one-level branch was only sprouted in every strain, and the secondary branch branch is more, can avoid 1 grade of branch of seedling more, is unfavorable for the drawback that straight form is cultivated with material.
2) after adopting this base fertilizer application process, can not only make the treelet root system recover rapidly growth vigor, strengthen the adaptive capacity to environment, and can provide growth necessary nutrient component, avoid fertilizer damage, improve the planting survival rates of going up a hill.
3) key of nursery stock transplanting method is that cuttage seeding goes out garden trimming method, root-growing agent aqueous solution soaking method and transplants season.After outplanting, prune, not only convenient transportation, and can reduce the evaporation discharge of acrial part after the field planting of going up a hill, avoid, because root system does not recover the physiological drought death that water, fertile absorbing capacity cause, improving transplanting survival rate; Only stay the trunk exposure ground of 5cm, can reduce the sprouting of 1 grade of major branch in the early spring in the coming year, be conducive to the tree-like cultivation of straight form.Use 20mg.L
-1GGR root-inducing powder aqueous solution soaking process, can not only improve the sprouting of fibrous root, and make root system suction moisture, improve transplanting survival rate.After beech tree fallen leaves, be only that acrial part stops growing, root growth will just stop by the end of November.Select this to transplant in season, because of the aerial growth gesture a little less than, can slow down the demand pressure of Root Absorption liquid manure, make the supply of liquid manure only reach bottom contentedly and divide the recovery growth of root system to get final product.After temperature rise in the early spring in next year, root system recovers growth vigor fully, can meet the liquid manure demand of acrial part, thereby improves transplanting survival rate.
