The cuttage breeding method of south blueberry
Technical field
The invention belongs to blueberry propagation technique field, particularly relate to a kind of cuttage breeding method of blueberry.
Background technology
Blueberry belongs to Ericaceae Vacciniodeae genus vaccinium plant, and have kind more than 400, it is distributed widely in the Northern Hemisphere.China blueberry is produced cultivation and is still in the starting stage, and from Jilin, Shandong, Liaoning etc. economizes and develop into the south of the lower reaches of the Yangtze River gradually.Blueberry is a kind of novel fruits of high nutritive value, and economic worth is high, has good development prospect, but in industrialization is produced, blueberry breeding is a great problem that those skilled in the art face always.Blueberry is generally based on cottage propagation, and blueberry cottage propagation more general small berries fruit tree survival rate is low, and technical requirement is high, in all parts of the country extensive to the research of blueberry cuttage technique.Due to the impact of climatic environmental factor, the cutting plantation difference of same kind in different regions is larger.
Cottage propagation in the past generally adopts following operation:
1, the selection of cutting medium: the main plurality of raw materials that adopts is prepared, and material composition contains river sand, sawdust, the peat composed of rotten mosses, curdy fur moss, perlite etc., and disinfects with 500 ~ 600 times of carbendazim;
2, the selection of root-growing agent: root-growing agent in the past generally uses the methyl α-naphthyl acetate of 2000 ~ 3000ml/l, this root-growing agent process blueberry branch DeGrain, rooting rate is lower.
3, the selection in cuttage period: be generally selected in 3 ~ June cutting experiment better.
The blueberry cultivation root-growing agent adopting methyl α-naphthyl acetate and the composite composition of heteroauxin is referred in CN102138529A Chinese patent literature, it mentions that the root-growing agent formula of use is for methyl α-naphthyl acetate and heteroauxin, and be directly soluble in water, but from the physicochemical property of methyl α-naphthyl acetate, heteroauxin, they are all the solid matters being insoluble in water, being soluble in organic solvent, experiment also shows, methyl α-naphthyl acetate and heteroauxin dissolve insufficient in water, there is deposit seed, be difficult to the effect reaching dispersed and effective utilization.The method adopting indolebutyric acid to make blueberry Rapid Rooting as root-growing agent is referred in CN102613078 Chinese patent literature, what it adopted is dissolve indolebutyric acid with NaOH, use water constant volume, but experiment shows, the rooting efficiency of alone indolebutyric acid is comparatively limited, and still have precipitation with after NaOH dissolving, the constant volume that adds water, do not reach homodisperse effect.In addition, this root-growing agent is mainly applied to plantlet in vitro, is not applied to cuttage branch example.The root-growing agent preparation mentioned in CN102668853A Chinese patent literature take water as lysate, and water dissolves insufficient to indolebutyric acid, placement a few minutes will precipitate, do not reach dispersed effect, also mention in matrix of taking root in the document and have employed the peat composed of rotten mosses, but in peat composed of rotten mosses matrix, germ is many, as sterilization is not thorough during use, to serious sick worm harm be brought to cuttage seeding, affect blueberry seedling quality.
In addition, existing root-growing agent compound method is generally make solvent with water or be first dissolved in alcohol to use water constant volume again, and this kind of method does not consider the abundant dissolving of solute and the sedimentation problem after dissolving, and reduces the effectiveness of root-growing agent; In addition, with alcohol dissolving water constant volume, alcohol is difficult to distribute, and all may injure, reduce further the useful effect of root-growing agent in cuttage to root system of plant and root upper part.
Visible, above-mentioned defect finally all can have influence on the application effect of root-growing agent and the successful reproduction of blueberry.
