Abstract
The invention discloses a cuttage propagation method of magnolia liliiflora twigs. The method comprises the following steps of: collecting cutting slips with the average length of 8-10 cm from a parent plant, then soaking the root parts of the cutting slips in a rooting reagent for 3-15 hours, and finally carrying out cuttage of the soaked cutting slips in a medium for propagation and rooting, wherein the cuttage depth is 3-4 cm, the relative air humidity in a grow seedling room during cuttage is required to be 80-95 percent, the temperature is controlled to be 18-28 DEG C, illumination is required for 6-7 hours per day, and the illumination intensity is 2000-3000 lux; and after cuttage under controlled humidity, immediately watering thoroughly, thereby sealing the cuttage soil and the notches, and improving the humidity of the soil. The cuttage propagation method of magnolia liliiflora twigs has the advantages that the survival rate of the cuttage propagation of the magnolia liliiflora twigs can be improved, the survival rate is more than 50 percent, and the growth vigour of the cutting seedlings can be improved.
Description
Technical field
The present invention relates to the propagation technique of a kind of trees, is a kind of purple yu-lan (Magnolia liliflora) softwood cutting propagation method specifically.
Background technology
Purple yu-lan (Magnolia liliflora) originates in ground such as Hubei, Shaanxi, Sichuan, Yunnan for the Magnoliaceae yulan belongs to the big shrub of fallen leaves, and all there is cultivation in the existing Yangtze river basin and Shandong, Guizhou, Guangxi; Tree-like haing a graceful carriage, full of leaves shade is dense, spends big and gorgeous; 3-Hua Xianye in April is open, and the outside is yellow, the inner face near-white; Big as the nib of bud shape is so there is the title of marlinspike.It likes light, and is not cold-resistant, should be grown in acidity, is rich in humus, well-drained place.This kind is long at China's cultivation history, and isolated planting, group planting, to do street tree all very attractive in appearance, be courtyard greening, beautify, the fine tree species of sweetening treatment.
Methods such as plant division, press strip, cuttage and tissue culture are adopted in the vegetative propagation of purple yu-lan (Magnolia liliflora) at present usually, but cuttage survival rate is lower.
Summary of the invention
Goal of the invention:, the object of the present invention is to provide a kind of purple yu-lan (Magnolia liliflora) softwood cutting propagation method that can improve cuttage survival rate in order to overcome the deficiency of prior art.
Technical scheme: in order to solve the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of purple yu-lan (Magnolia liliflora) softwood cutting propagation method; At first gathering average length from maternal plant is the slotting fringe of 8 ~ 10cm, and the base portion of inserting fringe then soaked in root-growing agent 3-15 hour, and the slotting fringe cuttage after will soaking is at last bred in matrix and taken root; The cuttage degree of depth is 3 ~ 4 cm; The indoor air relative humidity that requires during cuttage to grow seedlings is controlled at 18-28 ℃ in 80-95%, temperature, also takes illumination 6-7 hour/day simultaneously, and intensity of illumination is the 2000-3000 lux; Water once permeablely after the controlled humidity cuttage immediately, both can make and insert earth and otch connects airtight, can improve soil moisture again.
In order to improve rooting rate, said root-growing agent is formulated by following component: ABT1 number 400 ~ 600mg, sucrose 20 ~ 30g, vitamin D 10 ~ 15mg, ammonium nitrate 5 ~ 6g, water 1kg.
Said matrix is vermiculite and perlitic mixture, and wherein vermiculite and perlitic weight ratio are 1:1.
Beneficial effect: compared with prior art, advantage of the present invention is: can improve the survival rate of purple yu-lan (Magnolia liliflora) softwood cutting propagation, make survival rate more than 50%, can also improve the growing way of cuttage seeding.

Cultivate and observe spray one-tenth situation alive after 30 days, survival rate reaches 57%.
Set forth beneficial effect of the present invention through comparative trial below.
The slotting fringe cuttage of 1, from maternal plant, gathering average length 5,8,10,13 cm respectively is identical matrix, and cuttage fringe rooting rate is respectively 37%, 55%, 58%, 39%.Hence one can see that, and the rooting rate of cutting length when 8 ~ 10cm is the highest, and the cuttage rooting ability increases with cutting length to a certain extent, but when surpassing certain-length, rooting rate then descends.This possibly be because to insert fringe long, waste material then, and also low because of the subsoil temperature, poor aeration influences healing and taking root, even causes and insert the fringe base portion and rot to cause death, and is unfavorable on the contrary taking root.Equally, cutting length is too short, because the nutrient supply deficiency of itself also is unfavorable for taking root.
2. the influence of cutting medium to taking root: in the purple yu-lan (Magnolia liliflora) epicormic branch cuttage; Slotting fringe cuttage in 4 kinds of matrix that clip length is identical; These four kinds of matrix are respectively: plain sand, vermiculite, perlite, weight ratio are the vermiculite of 1:1 and the matrix that perlitic mixing forms, and insert the average rooting rate of fringe and are respectively 32%, 38%, 42%, 55%.Hence one can see that, and the rooting percent of cuttage is the highest in the matrix of vermiculite and perlitic mixing formation, and the rooting percent of cuttage is minimum in plain sand.If it is heavy to insert the earth stickiness, impeded drainage then, excess moisture is inserted in the earth and is lacked oxygen, not only suppresses to insert the respiration of fringe, and possibly change metabolic process, thereby suppress to take root.Therefore, when carrying out cottage propagation, answer the good matrix that forms with vermiculite and perlitic mixing of permselectivity as slotting earth.
3, root-growing agent is handled the influence to taking root: use indolebutyric acid (IBA), No. 1, root-inducing powder (ABT), slotting fringe that methyl (NAA) is identical with the same concentrations control treatment of the root-growing agent described in the embodiment of the invention 1 respectively.Insert the average rooting rate of fringe and be respectively 35%, 40%, 32%, 55%.Rooting percent with the root-growing agent in the embodiment of the invention 1 is handled is more much higher with the rooting rate of indolebutyric acid (IBA), No. 1, root-inducing powder (ABT), methyl than single.
Claims (3)
