Description

Drupe fruit tree and the tender slightly cottage method of stock

Technical field

The present invention relates to a kind of cuttage seedling raising method, be specifically related to drupe fruit tree and the tender slightly cottage method of stock, belong to plant Reproduction technique field.

Background technology

Cuttage is a traditional plant asexual multiplication technology, and Studies on Fruit Cutting Propagation just had begun to before 2000 should With, domestic through development for many years, cuttage technique reaches its maturity, in recent years, along with auximone and auto-spraying system device Application, its development is maked rapid progress.Tone fruit trees abundant species, including Fructus Persicae, Lee, Fructus Pruni, Fructus Pruni pseudocerasi etc., its main modes of reproduction is transferred Connect breeding, cottage propagation etc..Cuttage is also used for stock breeding.At present, the cuttage research of China tone fruit trees and stock also exists Constantly among progress, existing cottage method mainly uses semi-lignified cuttage, but has the disadvantage that

(1) the drupe fruit tree such as cottage propagation rooting rate such as Fructus Persicae, Fructus Pruni, Lee, Fructus Pruni pseudocerasi is low, and some kind is even difficult to take root.

(2) existing cuttage technique is mainly to cut branch and is cut into segment cuttage in substrate, different parts cuttage rooting difficulty or ease Degree is different, causes cuttage rooting time difference relatively big, causes management difficulty to strengthen.

(3) existing cuttage technique cutting meristematic capacity is weak, and auxin content is low, takes root relatively slow, and the high temperature of environment is high Wet it be easily caused in substrate the breeding quickening of various pathogen and cause cutting bottom to be rotted, have impact on cutting survival rate.

Summary of the invention

The technical problem to be solved in the present invention is for above not enough, it is provided that drupe fruit tree and the tender slightly cottage method of stock, logical Cross continuous pinching and spray the series of measures such as the basic element of cell division and auxin, make tender slightly organize to be in all the time enliven mitogenetic shape State, auxin content is high, it is achieved following goal of the invention:

(1) cottage method of the present invention, cottage propagation rooting rate is high；

(2) cottage method of the present invention, cuttage rooting concordance is good；

(3) cottage method of the present invention, shortens rootage duration, improves cutting propagation rooting rate and emergence rate, improves surviving of cutting Rate；

(4) cottage method of the present invention, reduces seedling cost, improves market supply ability.

For solving above-mentioned technical problem, by the following technical solutions:

Drupe fruit tree and the tender slightly cottage method of stock, it is characterised in that: include cultivating there is the cutting of strong meristematic capacity, cutting Process, tender slightly cuttage.

The following is and the further of technique scheme is improved:

Described cultivation has the cutting of strong meristematic capacity, chooses tissue culture seedling as adopting fringe strain；Described seedling branch growth To pinching when 30～50cm, and pinching continuously.

Described cultivation has the cutting of strong meristematic capacity, spray in 1～3d after continuous pinching the basic element of cell division 20～ 100ppm adds naphthalene acetic acid 50～150ppm mixed solution, sprays more than 2 times continuously.

It is described that to adopt fringe strain be 1～3 year raw tree.

Described cultivation has the cutting of strong meristematic capacity, and continuous pinching more than 2 times, young sprout length is to more than 30cm, then sprays The basic element of cell division 20～100ppm adds naphthalene acetic acid 50～150ppm mixed solution, and after spraying, a 3～5d interior clip shoot apex are tender Slightly as cutting.

The process of described cutting: the every segment length of cutting 15～25cm, retains top and top 5～6 blades, rest blade Extracing, cutting lower cut is tiltedly cut domatic about the 1-2cm of reservation and lower end is cut flat；Base diameter 0.2-0.5cm of cutting.

The process of described cutting, the carbendazim that cutting mass ratio is 2:1 after cutting and thiophanate methyl wettable powder Agent 800～2000 times of immersions bubble 5～8min carry out disinfection, then with concentration than be 2:1 NAA+IBA root-growing agent 300～ 600ppm solution soaking cutting base portion is at 2～3cm 5～10min.

Described tender slightly cuttage, cuttage seeding row spacing is 10-15cm × 12-20cm, and the cuttage degree of depth is 6～8cm；After cuttage in canopy Air humidity is maintained at 85%-95%, and temperature controls at 20-32 DEG C, less than less than 35 DEG C.

Described tender slightly cuttage, cutting medium uses perlite and the peat composed of rotten mosses, is mixed for 1:1 by volume, with 0.1% Divide after potassium permanganate solution spray disinfectant in slotting machine, stromal thickness 15cm, irrigate with clear water.

Described tender slightly cuttage, cutting medium is with weight portion, including following components:

Meerschaum 30 parts, 10 parts of D-alkene, carboxymethyl cellulose 4 parts, star shellfish Sargassum fusiforme (Harv.) Setch 5 parts, Rhizoma amorphophalli powder 6 parts, amino-oligosaccharide 0.5 part, biochemical yellow humic acid 12 parts, Huai Goat 5 parts, graphene oxide 2 parts.

At present, cuttage technique uses cutting to be semi-lignified branch, and rooting rate is low, and this technology improves rooting rate and mainly arranges Execute and be: 1. selecting tissue cultured seedling to build cutting orchard, only adopt fringe from 1～3 year raw tree, treelet can keep plant tissue active state；② Pinching makes young sprout then maintain the tender and easy differentiation state of cell of children continuously；3. young sprout is used to replace original semi-wooden scion, newly Tip tissue is in mitogenetic state, is conducive to taking root；4. spray the basic element of cell division and naphthalene acetic acid, and again spray before adopting fringe, make Histiocyte maintains ' young ' active state, increases tree somatic cell division cellulose content, easily forms callus, increases thing of taking root Matter content, makes to take root easier.Above-mentioned measure is with the use of embodying good result.

Compared with prior art, the invention has the beneficial effects as follows:

(1) cutting propagation of the present invention, rooting rate significantly improves, and as a example by Fructus Persicae new varieties ' the U.S. moon ', rooting rate reaches more than 97%, often Rule semi-lignified cutting plantation is only 15%, improves 82 percentage points, and rooting rate improves more than 6 times；

(2) cutting propagation of the present invention, tender slightly tissue is in mitogenetic state of enlivening, and auxin content is high, it is achieved that cuttage rooting Concordance, to 25d, major part cutting is taken root；

(3) cutting propagation of the present invention, shortens rootage duration, shortens 5～7d than the conventional semi-lignified cuttage root-taking time；

(4) cutting propagation of the present invention, emergence rate significantly improves, and spring in next year investigates emergence rate, reaches 97.7-98%, more wooden than half Change cuttage and improve 40.7-41.5 percentage point；Economic benefit improves more than 80%；

(5) problem that present invention, avoiding that common cuttage root-taking is slow and cutting rots；

(6) method of the present invention, management difficulty is low, has the feature of popularization simple to operate, easy.

Detailed description of the invention

The detailed description of the invention of the present invention is described with concrete case study on implementation below:

Embodiment 1 drupe fruit tree and the tender slightly cottage method of stock

Illustrate as a example by peach variety ' the U.S. moon ', test by the present embodiment in proving ground, academy of agricultural sciences of Weifang City, Test and set process group and matched group:

Process group: the cottage method of the employing present invention:

Comprise the following steps:
