According to the invention, by combining the mixed growth regulating agent with the soil layered matching technology, problems in the plant cutting method are solved; working procedures are simple; cost is low; survival rate of transplanting is high and can reach more than 90%; cultivation speed is fast; large quantity of high-quality seedlings can be obtained by use of the method; and the method has a profound promotion value.

Description

A kind of method that can significantly improve plant cuttage survival rate of seedling

Technical field

The present invention relates to cuttage raise seedling technique field, particularly a kind of method that can significantly improve plant cuttage survival rate of seedling.

Background technology

The cuttage and seedling culture of plant inserts in soil by part nutrition organs such as the root of plant, stem, leaves, utilizes its regeneration capacity, makes it to take root to send out branch, becomes new plant.Cottage propagation can keep the merit of parent, does not resemble seed propagation and produces variation, can shorten breeding time compared with seedling simultaneously.Though cuttage and seedling culture is simple, planting percent also non-easy thing be ensured.Affecting the factor that cuttings survives a lot, except itself taking root outside the Pass difficulty or ease, quality etc. have with slotting material, more having inseparable relation with cutting medium.General conventional matrix has two classes: a class has soil matrix matter, and its main component is the Humus of soil or similar soil; Another kind of, be non-soil material, as perlite, river sand etc.Comparatively the latter is high for the former content of organic matter, and the ratio of microorganism is corresponding also high, and the surface of a wound inserting material is easily polluted.Simultaneously because the former density is much larger than the latter, cause permeability to be deteriorated, this brings difficulty just to slotting taking root of material.But it can supply nutrient in time for the individual plants after taking root.The latter is then on the contrary, inserts the take root situation of material in soilless substrate and is better than the former, can not get required nutrient after just taking root, and causes individual plants hungry and causes seedling to be not so good as the former stalwartness.At present, in the cuttage and seedling culture field of China, due to many reasons, all can not spread out all sidedly.Misapplication due to matrix causes the cuttage and seedling culture of traditional approach to there is following defect, causes that survival rate is low, speed of production is slow: (1) plant rooting is slow, and root of hair causes the not enough death of nutrition organs moisture content and nutrient less; (2) in soil, fungi is more causes plant to rot; (3) after root of hair because oligotrophy causes later death.

Summary of the invention

The invention provides a kind of method that can significantly improve plant cuttage survival rate of seedling, overcome traditional cuttage and seedling culture have that plant rooting is slow, root of hair causes nutrition organs moisture content less and nutrient not enough dead, in soil, fungi is more causes plant to rot, because oligotrophy causes the defect of later death after root of hair, provide a kind of by mixed growth conditioning agent and soil layering collocation technique solution plant cuttage method Problems existing, the method for plant cuttage survival rate of seedling can be significantly improved.

The present invention is achieved through the following technical solutions: a kind of method that can significantly improve plant cuttage survival rate of seedling, comprises the steps:

(1) soil layering collocation technique: the lower floor that is prepared as in seedbed is detritus soil, yellow earth and anthropogenic soil, and upper strata 3-5cm is red soil;

(2) cuttings is chosen and pruning: in annual spring and autumn, get raw semi-lignified or lignification branch 5-10cm then, save with more than 2, morphology lower end Leaf Pruning is fallen, lower about the 1cm of joint is trimmed to inclined-plane, and morphology upper end blade retains 1/3 or all prune away, and is 1 bundle by 50, the branch pruned, tie with rubber, accomplish often to tie lower neat uneven;

(3) cuttings sterilization induce process with mixed growth conditioning agent: the cuttings of having pruned all be immersed in new 1/1000 potassium permanganate disinfection solution prepared and soak 50 minutes, after branch morphology lower end 2-3cm is immersed in 2-3 in the mixed growth conditioning agent of 100PPMIBA+50PPMNAA+1/4MS individual hour;

(4) cuttage and heat and moisture preserving measure: step (3) is sterilized with on induce the cuttings handled well to insert in seedbed that step (1) puts in order, the degree of depth is 3-5cm, spacing is that 7*7cm does not block with blade and is advisable, spray 3-5 back and forth with clean irrigation water, until seedbed infiltration water outlet is advisable, every furrow thin bamboo strips used for weaving is barricaded as a high shed for 50-60cm, can not be too high or too low, live with plastic film covering, surrounding soil kills, and can not have omission; If sunshade need be taken in outdoor seedbed, with the sunshade net shading of 75%;

(5) final-period management: whether have gas leakage, have the globule for normal phenomenon with film if observing seedbed in 30 days in cuttage, if do not need to detect nursery soil humidity, and carries out period drainage works; Within 30 days, observe cuttings afterwards and whether grow young leaves, if young leaves grows, the growing state of cuttage seeding can be checked from limit, if radical reaches more than 5 or film can be opened more than 3cm by root length, 1 Zhou Houke sprays foliage fertilizer growth promoting effects, when shoot semi-lignified, can transplant after blade covers mutually, general selection is after 3 months.

Compared with prior art, the present invention has following outstanding advantages and effect: (1) the present invention solves plant cuttage method Problems existing by mixed growth conditioning agent and soil layering collocation technique, red soil has that organic matter is low but the soil is porous, fine and smooth, paucibacillary feature, detritus soil, yellow earth and anthropogenic soil be rich in organic matter be beneficial to plant growth but containing bacterium and sandstone many, therefore, soil layering collocation technique of the present invention is the layer rhizogenous that slotting material creates an existing environment of well taking root, there is again the nutritive layer being rich in nutrient component, slotting material is fully taken root in layer rhizogenous, more can lead with the elongation of root and by the fertilizer that becomes of root, new root is extended to rapidly in nutritive layer, to supplement the nutrient inserted material and consume in the stage of taking root, improve the success rate of plant cuttage propagation, (2) operation of the present invention is simple, with low cost, transplanting survival rate is high, survival rate up to more than 90%, reproduction speed is fast, be obtain a large amount of plant high quality seedling method for solution, there is promotional value.
