Abstract

The invention discloses a breeding and cultivating method for michelia figo. Breeding and cultivating are carried out by adopting a layering method. The breeding and cultivating method comprises the following specific steps: (1) selecting parent branches in April every year; (2) determining the length of each parent branch, and carrying out ring-barking on each parent branch until xylem appears; (3) coating xylem with naphthyl acetic acid so as to stimulate ring-barked part to root, and carrying out bagging and matrix filling so as to provide nutrients; (4) carrying out cultivating and rooting, carrying out maternal plant scissoring separation, and carrying out transplanting; and (5) carrying out young seedling raising, and carrying out fertilizer and water management. The breeding and cultivating method has the advantages that the method is simple, the rooting speed is high, and the survival rate of transplanting is high.

Description

The process for breeding and culturing of a kind of Michelia figo

Technical field

The present invention relates to Cultivating techniques field, gardens, be specifically related to the process for breeding and culturing of a kind of Michelia figo.

Background technology

Michelia figo, Latin literary fame: Micheliafigo (Lour.) Spreng.Evergreen shrubs, high 2-3 rice, bark taupe, branch is dense; Leaf keratin, narrow ellipse or the shape of falling ovum ellipse, the florescence 3-5 month, the fruit phase 7-8 month.Originate in each provinces and regions, In South China south, Dinghushan, guangdong has wild, is born in Schattenseite shaw.Fragrance flowers and trees, bud profit as jade, if fragrant deep and remote blue.

Originate in south China.Michelia figo can breed by modes such as cuttage, high-pressure process and graftings.Cuttage is suitable for late July to early September for it, desirablely still do not send sprouting but leave lignification branch or the terminal bud about 15 centimeters of 3 ~ 8 leaves, attaching root of hair element in cuttings base portion is inserted on sand, separately give and suitably shade and keep environment moistening, within about 2 ~ 3 months, can take root, then transplant in the next spring; After the high pressure genealogy of law is best suited for and blooms, namely between 4 ~ May row for best, if the thick and strong branch that selected plant is 2 ~ 3 years age carries out soil pressure, then can take root through 3 ~ 4 months; More not by the grafting that industry is commonly used, should implement between 5 ~ June, be often using lily magnolia as stock, can grow fast after surviving.The Michelia figo of the plump fleshiness of root, not resistance to transplanting, transplants appropriate to the occasion multi-band soil ball if really must carry out, the pruning of plant, integer be then survive the winter before be advisable.

Summary of the invention

The present invention is the process for breeding and culturing adopting the method for press strip to carry out a kind of Michelia figo of Michelia figo Propogation and culture.

A process for breeding and culturing for Michelia figo, adopt the planting of layer to carry out breeding and culturing, its concrete steps are as follows:

in annual April, select the growth of life in 2 years excellent, the branch that tissue is substantial, healthy and strong, as breeding kind of a bar;

michelia figo branch length is determined at 15-20cm moderate, and at the native root of hair position of bag, do the ringing of width 0.5-1cm, barking depth reaches xylem;

xylem after the peeling of Michelia figo branch, coating concentration is the naphthalene acid solution of 40mg/L, then plastic sack on the lower end cover at band girdle place, lower end is tightened, upper end open, and at the in-built liver moss of bag and the vermiculite suctioning moisture, and keeping moisture moderate, water content is at 40-50%;

after cultivating 1 month, get final product root of hair, until new root must grow vigorous after, can by shoot shear depart from parent, transplant separately;

after transplanting, put sunlight place half a day, put shady and cool place half a day, can not tan by the sun, increase illumination gradually after 1 week, every day increases 1h, until equally carry out rich water quality management with maternal plant.

Beneficial effect of the present invention: there is simple, the easy support of Propogation and culture method and hold, adopt band girdle on female branch, and be coated with methyl α-naphthyl acetate stimulate band girdle place xylem to grow new root fast must, and supply female branch nutrient by matrix, after shearing, transplanting success is high, can survive fast and potted plantly carry out identical clay fertilizer water management with similar.

Embodiment

A process for breeding and culturing for Michelia figo, adopt the planting of layer to carry out breeding and culturing, its concrete steps are as follows:

in annual April, select the growth of life in 2 years excellent, the branch that tissue is substantial, healthy and strong, as breeding kind of a bar;

michelia figo branch length is determined at 15-20cm moderate, and at the native root of hair position of bag, do the ringing of width 0.5-1cm, barking depth reaches xylem;

xylem after the peeling of Michelia figo branch, coating concentration is the naphthalene acid solution of 40mg/L, then plastic sack on the lower end cover at band girdle place, lower end is tightened, upper end open, and at the in-built liver moss of bag and the vermiculite suctioning moisture, and keeping moisture moderate, water content is at 40-50%;

after cultivating 1 month, get final product root of hair, until new root must grow vigorous after, can by shoot shear depart from parent, transplant separately;
