Description
Technical field
The present invention relates to a Plants asexual reproduction method, specifically relate to a kind of L. styraciflua hardwood cutting and seedling raising method.
Background technology
L. styraciflua (Acer palmatum) is Aceraceae (Aceraceae) Acer (Acer) deciduous tree or dungarunga, originates in each province, China Yangtze river basin, in Japan, Korea S etc., distribution is also arranged.The L. styraciflua tree performance is graceful, leaf peculiar, and in good day of spring and autumn, color leaf gardenful, be world-renowned foliage tree kind.The L. styraciflua garden-variety is various, and the afforestation application is very extensive.
The vegetative propagation of plant can keep maternal good characteristic, the cultivation in a organized way of the asexual reproduction method of L. styraciflua, grafting and cuttage etc.Wherein, tissue culture technique requires high, complicated operation, production cost costliness; Biennial above L. styraciflua stock need to be first cultivated in propagation by grafiting, then required L. styraciflua kind scion is grafted on stock to the cultivating seedlings phase that therefore need to grow; There is in recent years the scholar to carry out the test of L. styraciflua softwood cutting propagation, the honest summer high temperature of epicormic branch cuttage period, need to possess full exposure spraying system device can implement, and the method has greatly limited seedling manufacturing enterprise and the peasant household of growing seedlings carries out breeding on a large scale of L. styraciflua seedling.The cuttage implementation condition of L. styraciflua is easy, processing ease, and reproductive-cost is lower; By literature search, the domestic report that there is not yet.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of simple to operate, with low cost, L. styraciflua hardwood cutting and seedling raising method that reproductive efficiency is high.
Technical scheme: the present invention is achieved through the following technical solutions:
A kind of L. styraciflua hardwood cutting and seedling raising method, is characterized in that, comprises the following steps:
(1) cutting time: be advisable before L. styraciflua rudiment in spring foliation;
(2) be equipped with cutting medium: vermiculite and peat are mixed and made into to cutting medium by the volume ratio of 1: 2～1: 3, dilute 800～1000 times of medicine liquid sprays cutting mediums of sterilizing with 50% carbendazol wettable powder;
(3) preparation root-growing agent: by indolebutyric acid, manganese sulphate, Cobastab
1Be mixed in proportion, standby;
(4) prepare cuttings: select L. styraciflua tree crown middle and upper part gave birth in 1 year healthy and strong, lateral bud is full, without the branch of damage by disease and insect.Clip length is 8～12cm, diameter be the branch of 0.3～0.8cm as cuttings, the upper and lower clip of transplanting a cutting is truncate, upper clip is apart from clip bud 0.5～1cm, clip is level and smooth, every root cutting will have 2～4 full buds;
(5) cuttings is processed and cuttage: the base portion of cuttings is soaked respectively in clear water, liquor potassic permanganate after, insert in the root-growing agent that step (3) prepares and soak, after the cutting medium that inserting step (2) configures, water permeable;
(6) insert after management with transplant: the cuttings of cuttage in step (4) is placed in to plastic canopy insulation, moisturizing, and wherein in shed, temperature remains on 25 ℃ of left and right, and relative moisture reaches more than 80%; After cuttage, spray 500～800 times of 50% carbendazol wettable powder dilution thimerosals 1 time every 10～15d, prevent from going rotten, remove in time the cuttings of rotting; After 20～30 days, the cuttings base portion starts to form callus, from the callus of cuttings base portion or the skin zone of cuttings base portion, bears adventive root in the time of 40～60 days, transplants afterwards in 70～80 days.
2, L. styraciflua hardwood cutting and seedling raising method according to claim 1, is characterized in that, the cutting time described in step (1) is that mid-March in spring is to by the end of March;
3, L. styraciflua hardwood cutting and seedling raising method according to claim 1, it is characterized in that, root-growing agent described in step (3) be indolebutyric acid 200～400mg be dissolved in 20～40ml 95% ethanol in, add manganese sulphate 20～30mg, Cobastab
13.0 after～5.0mg, add water to 1kg, make after mixing;
4, L. styraciflua hardwood cutting and seedling raising method according to claim 1, it is characterized in that, it is the base portion of cuttings is soaked to 6～12 hours in clear water after that cuttings described in step (5) is processed, with in 0.5% liquor potassic permanganate, dipping 1～2min, insert in the root-growing agent that step (3) prepares and soaked 1～2 hour.
Beneficial effect: L. styraciflua hardwood cutting and seedling raising method of the present invention, cuttage survival rate reaches more than 80%, than the cost of L. styraciflua epicormic branch cuttage 30%～50%; It is only method for tissue culture cost 20% left and right; With L. styraciflua propagation by grafiting, compare, shorten growing-seedling period 2～3 years.This method is easy to operation, has that cost is low, specification requirement is simple, the advantage such as easily applies, and has important application and promotional value in the production of L. styraciflua sapling multiplication.
