Abstract
The invention relates to a cuttage method, in particular to a styrax hypoglauca cuttage propagation method. Currently, mass propagation of high-quality styrax hypoglauca seedlings is affected due to low cuttage survival rate of styrax hypoglauca. The styrax hypoglauca cuttage propagation method includes the following steps: 1), collecting and treating cuttings, namely in the time period after defoliation and before germination, taking branches, higher than the ground by 0.2m, of seedlings of one year old, pruning lateral branches and only retaining trunks, cutting the trunks into short branches of 0.4-0.5m according to length of the trunks, and sealing two ends of the short branches by wax; 2), refrigerating the cuttings, namely bundling multiple cuttings, wrapping the cuttings by degreased cotton, using a sprayer to spray water to enable the degreased cotton to be wet, placing the cuttings wrapped by the degreased cotton in a plastic bag for sealing, and disposing the plastic bag in a low-temperature storage cabinet of 2-5 DEG C for storing and standby use; 3), preparing a seedling bed; 4), performing cuttage of the cuttings; (5), taking management measures. The styrax hypoglauca cuttage propagation method is high in cuttage survival rate which can reach 70%, low in cost, easy in operation and capable of realizing mass propagation of high-quality clonal styrax hypoglauca seedlings.
Description
Technical field
The present invention relates to a kind of cottage method.
Background technology
Styrax tonkinensis Craib ex Hart (Styrax tonkinensis) belongs to Styracaceae (Styracaceae) Styraax (Styrax) deciduous tree, heliophilous species, natural distributed is in China south China, southwest and extend to Vietnam and Laos, has crossed over 3 temperature bands such as north tropic, south subtropics and middle subtropical zone.Rapidly, the phase of becoming a useful person is short in growth, is the desirable seeds of pulpwood in ultrashort rotation; Seed kernel oil be take unsaturated fatty acid as main, and total content reaches 85.4%, can production biodiesel; Tree-like grace, floral white bunchiness, when in full bloom, full-blown flowers, like snow, have ornamental value; Its resin claims " styrax ", has important medical value.Styrax tonkinensis Craib ex Hart as logging with, oil with, medicinal and the various value seeds such as view and admire, research was on the increase both at home and abroad in recent years.Aspect breeding and cultivation, solved the technical problems such as seed seedling-raising, forest plantation cultivation, but vegetative propagation technique not yet obtains breakthrough.Vegetative propagation can keep parent's merit, in forest cultivation and genetic improvement, plays key foundation effect.Cuttage, as a kind of low cost, workable styrax tonkinensis Craib ex Hart vegetative propagation technique, not yet by system research and proposition, has affected the breeding in enormous quantities of styrax tonkinensis Craib ex Hart high quality seedling to a certain extent.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is that prior art scheme is improved and improved, and provides a kind of styrax tonkinensis Craib ex Hart cuttage breeding method, to reach the object that improves cuttage success rate.For this reason, the present invention takes following technical scheme.
A styrax tonkinensis Craib ex Hart cuttage breeding method, is characterized in that comprising the following steps:
1) fringe bar gathers and processes: after fallen leaves, to before sprouting, get 1 year branch more than liftoff 0.2m of raw nursery stock, wipe out side shoot and only retain trunk, depending on trunk length, being cut is the brachyplast that 0.4～0.5m grows, the brachyplast mouth of sealing with wax for two ends;
2) fringe bar refrigeration: by after many fringe bar bindings, with absorbent cotton parcel, make absorbent cotton moistening with sprayer water spray, then the fringe bar of wrapping up in absorbent cotton is outward put into plastic sack and seal, be placed in 2～5 ℃ of low-temperature conservation cabinets and store standby;
3) prepare in seedbed: take cement pit as cuttage seedbed, the perlite that in bed, paving thickness is greater than 15cm is as matrix, peripheral hardware shed, shed covers with film, before cuttage with the even spray disinfectant of liquor potassic permanganate;
4) cuttage cuttings: mid-April, mean temperature reaches 15 ℃ when above, and the fringe bar of storage is taken out, is cut into length 10cm～12cm, with the cuttings of 1 above bud; Bud is positioned at the upper position of cuttings, cuttings top lateral shear, lower end inclined cutting; By some cuttings, be one group, tie to be placed on and soak 4-8 hour, soaking depth 4～5cm containing in the mixed solution of GGR6, IBA of preparing; Before cuttage, first use the bamboo let thicker than cuttings to punch in matrix, the jack degree of depth 8～10cm, density be 10cm * 10cm or more than; Put into compacting matrix after cuttings, after having inserted, spray water saturated to matrix, then shed is built;
5) control measures: keep the corresponding humidity of matrix after cuttage, when temperature reaches 30 ℃, ventilation and heat is opened in shed two; After having more fibrous root to grow, transplant.
When mid-April, carry out cuttage, now temperature is high, and cytoactive is strong, and callus and root growth time can effectively shorten, and reduces the mildew and rot phenomenon of cuttings that in management process, unfavorable factor causes.Before cuttings is sprouted, take off and put into freezer, make it in resting state.
As the further of technique scheme improved and supplemented, the present invention also comprises following additional technical feature.
In mixed solution, the mass percent concentration of GGR6, IBA is respectively 300mgL
-1, 100mgL
-1.GGR6, IBA are all mainly used in taking root; Both mix the rooting rate that improves cuttings.
Cut-off footpath is that the cuttings of 0.41～1.0cm is for cuttage.
Cuttings is soaked 8 hours in mixed solution.
In mid-February, get 1 year raw nursery stock branch.Reduce cold preservation time, improve activity, meanwhile, reduce refrigeration cost.
Beneficial effect: the technical program has been filled up the technological gap of styrax tonkinensis Craib ex Hart cottage propagation, and cuttage survival rate is high, can reach 70%, and cost is low, easy operating, can realize the breeding in enormous quantities of styrax tonkinensis Craib ex Hart high-quality clone nursery stock.
