Abstract

A Podocarpus macrophyllus cuttage breeding method comprises the following steps: 1, selecting cuttings: selecting 10-15cm semi lignification Podocarpus macrophyllus branches with heels, removing blades on the lower portion of the branches, and keeping the upper 2/3 blades; 2, cutting treatment: using a knife to trim and smooth pedicles of the selected Podocarpus macrophyllus branches, immersing the lower 1-2cm of the branch into a naphthalene acetic acid auxin solution with concentration of 300mg/l, or spraying auxin on the surface of a seedbed at the rate of 500ml/square meter; 3, seedbed selection and processing; 4, drill holes; 5, cuttage; 6 post-cuttage management; 7, transplanting; 8 trimming moulding. The Podocarpus macrophyllus cuttage breeding method uses semi lignification branches with heels, so rooting is easier; the cuttings are disinfected and processed by auxin, and fertilization, weeding and insect control are timely carried out, thus improving Podocarpus macrophyllus cuttage survival rate.

Description

A kind of cuttage breeding method of podocarpus
Technical field
The present invention relates to the cuttage field of Nursery Stock is and in particular to a kind of cuttage breeding method of podocarpus.
Background technology
Podocarpus, the native China fir of another name, Podocarpaceae, Podocarpus evergreen needle arbor, up to 20 meters, the diameter of a cross-section of a tree trunk 1.3 meters above the ground reaches 60 centimetres; Bark grey or taupe, shallow lobe, flakiness shape comes off;Branch is carried out or oblique exhibition, closeer.Leaf helical form life, and strip drapes over one's shoulders pin Shape, micro-bend.Male cone spike, armpit life, base portion has several pieces of triangular shape bracts;Female cone list leave armpit, has stalk, and base portion has minority bud Piece, seed oval, tip is justified, meat aril atropurpureus when ripe, has white powder, plants support meat cylinder, redness or aubergine, The month at florescence 4-5, the seed 8-9 month is ripe;Podocarpus is distributed in Chinese many provinces and regions, cultivates and views and admires tree in flower garden, but wild tree Wood is few.The method of cutting propagation, has more than 2000 year history in China, extensively applies already in production practices, but existing During the cutting propagation of podocarpus, usually occur that podocarpus is affected by pest and disease damage or other extraneous factors, lead to into Motility rate is not high.
Content of the invention
The problem that the present invention solves is in the not high problem of the cuttage survival rate of podocarpus.
For solving the above problems, the invention provides a kind of cuttage breeding method of podocarpus, comprise the following steps:
(1) choose cuttings, selection growing way is preferable, leaf is dense, the semi-lignified with heel for the length 10~15cm is not set seeds Podocarpus branch, deducts branch lower blade, retains top 2/3 blade because the nutrient accumulation of branch intersection than other Local many, tissue tight, root of hair is easy compared with other positions;
(2) cuttings is processed, and base of a fruit head is repaired by the podocarpus branch scraper chosen smooth, and in order to promote cuttings, early healing is sent out Root, planting percent is high, carries out auxin process to cuttings before cuttage, by the podocarpus branch lower end 1~2cm choosing immersion concentration In methyl α-naphthyl acetate auxin solution for 300mg/l, or auxin is sprayed on seedbed surface with every square metre of 500ml;
(3) seedbed selects and processes, and selects the plot that fertile soil, loose, irrigation conditions are good, have a good transport service, site preparation Make well seedbed, spread the matrix that thickness is 15cm in seedbed, repave the yellow soil after 1 layer of 3cm, water to soil in the front seedbed of cuttage Earth water content reaches 50%, is carried out disinfection with 1000 times of liquid pouring seedbeds of thiophanate methyl, and sets up cool canopy, canopy is high before cuttage 150cm-200cm.
(4) draw hole, choose diameter 1cm about bamboo let, by one sharpening of bamboo let, according to cuttage spacing in the rows 10cm, line-spacing In the distance insertion seedbed of 15cm, the branch of depth ratio insertion is slightly shallow;
(5) cuttage, the 1/3~1/4 of branch lower end is inserted in the hole, and is compacted cuttings jam-packed conveniently, pours permeable, make to cut Mouth is contacted with soil, is beneficial to root of hair;
(6) manage after cuttage:
A. water in time after cuttage, carried out disinfection sterilization with 1000 times of liquid of thiophanate methyl pouring seedbeds, and spray and take root Liquid, makes nursery soil water content be not less than 70%, uses covering with ground sheeting cuttings, and mulch film height is 30-35cm;
B. when the good podocarpus of cuttage grows tall 5cm, apply fertilizer weekly once, soil applies the composite fertilizer of concentration 1%, blade face The potassium dihydrogen phosphate of spraying concentration 0.5%, with strong sprout, turns out more flourishing newborn root system;
C. when disease in podocarpus after cuttage, answer timely spraying insecticide, common insect pest has roundheaded borer, shell Worm, aphid and red spider etc., available DDVP, 1300~1500 times of spray solutions of flolimat ammonium, to not surviving and rotten Cuttings, pull up in time, concentrate burn it is impossible to lose on field ditch side.
(7) transplant, after cuttings cuttage completes 1 year, the spacing in the rows according to 50cm*50cm is transplanted.
(8) prune moulding, in conjunction with moulding demand, integrated use various moulding gimmick, progressively revise tree-like, reach required outer Shape effect, the added value of lifting podocarpus, podocarpus can be pruned throughout the year, mainly cuts off the branch of excessive growth, sick deadwood, to keep excellent U.S. tree-like, preferably in time bud is plucked when blooming, in order to avoid result consumes nutrient, affect growing way;Pruning may be used to down several sides Method:Prune off, will wipe out from base portion branch.By pruning off, stub ventilation and penetrating light is good, and nutrition supply is concentrated, and growth is vigorous.Treelet Prune off early, normal development can be conducive to grow;Prune off during shaping, the moulding branch staying can be made to obtain the nutrition of abundance, plus Rapid-result type;The bonsai of shaping, by pruning off, can play the effect of balanced nutrients, be allowed to old and do not wane;Short cut, will long shoot Cutting back, stimulates the axillary bud sprouting under clip, forms stronger side shoot, thus reaching its branch of rush, is easy to the purpose of moulding;Contracting Cut, cutting back is carried out to perennial branch, it is the effective measure reducing big tree, is also to promote rudiment shoot, recovers The important means of tree vigo(u)r.
Further, after applying fertilizer every time, the solution of blade must be attached to clear water drip washing, to avoid Jiao and hinder phenomenon, stand Then stop fertilising after autumn, allow seedlings plugging form wooden and semi-lignified and pass the winter safely.
Further, for making cuttage branch fully absorb auxin, branch soak time in auxin is 4 hours.
Further, for making nursery soil loose, cuttings fully absorbs fertilizer and nutrient in soil, seed bed preparation depth For 20cm.
Further, cutting time is the annual 5-10 month.
The invention has the beneficial effects as follows:A kind of cuttage breeding method of podocarpus of the present invention, chooses the semi-lignified with heel Branch can promote cuttage rooting to be easier, and by carrying out disinfection to cuttings and auxin is processed, and carry out in time applying fertilizer, remove Grass, deinsectization, can improve the survival rate of podocarpus cutting propagation.
