Abstract

The present invention discloses a propagation method for a huabancai weed cutting wood and relates to the asexual propagation of plants. A perennial vine in a natural state is used, a section of every two leaf buds is used as a cutting wood, and 3 to 5cm is left outside an upper bud and a lower bud. The upper part of the cutting wood is enswathed through plastic films, and a bud eye on the cutting wood is exposed during the enswathement. The length of the enswathement part accounts for two thirds of the total length of the cutting wood, and every 100 cutting woods are bundled into one bundle. The lower ends of bundled cutting woods are put in the root inducing powder physic liquor of which the weight concentration is 0.3%, and are soaked for 30 minutes, and then processed cutting woods are inserted into a fine sand bed. Parts at the lower parts of the cutting woods, which are not bundled with films, are all inserted in the sand, and one to two centimeters of the length of the enswathement part is inserted. Cuttage density is 5*20 centimeters, and the humidity of the sand bed is maintained. The sand bed covers 75 % of a shading net at a previous stage and covers 50 % of the shading net during germination, and transplantation is started when buds grow about nine to eleven centimeters. Seedlings are cultivated and managed according to normal cuttage seeding.

Description

Cutting propagation method for Huabancai weed

Technical field

The present invention relates to the method that is propagated from cuttings of a plant species, more particularly, the present invention relates to the cutting asexual reproduction method of health plant slide plate dish.

Background technology

Slide plate dish (Parabaena sagitata (Wall.) Miers.ex Hook.f.Thoms.) is menispermaceae (Menispermaceae) herbaceous perennial vine plant.The equal tool striped of stem branch is usually by rough hair shape pubescence, near sometimes nothing hair.The leaf papery, wealthy avette or oval shape is avette, and long 8～16 centimetres, can reach 25 centimetres sometimes, wide 5～9 centimetres, can reach 20 centimetres sometimes.The long gradually point in top, base portion arrow type, there is thin tooth at the edge to bastard, few full edge, 5～7 of palmate veins.Inflorescence umbrella room shape, single living or twin sometimes.Drupe is subsphaeroidal and flat slightly, is about 8 millimeters.Be distributed in provinces such as Yunnan, Guangdong, Hainan, Guizhou, Tibet.Its young stem and leaf is fabulous wild vegetable, and the torrid areas, Yunnan is extensively edible, has found a good sale in ground such as Sichuan, Chongqing, Guangzhou at present.Nutritious, the edible part of per 100 grams contains: 4.840 milligrams of carotenes, and 0.026 milligram of vitamin B1,0.390 milligram of vitamin B2,5.55 milligrams of Catergens are a kind of high-quality wild vegetables that the exploitation future is arranged very much.

But along with the minimizing of the forest resources, seed rareness under the slide plate dish nature mainly is artificial a large amount of its young stem and leaf of gathering, and the natural resources amount of this plant is reduced day by day, can not satisfy consumption demand far away.Therefore, pressing for artificial cultivation slide plate dish, is to realize tame primary technical problem and a large amount of nursery stocks are provided.

Summary of the invention

The objective of the invention is the actual needs at the production of slide plate dish, provide a kind of simple to operate, cost is low, is easy to obtain the cutting asexual reproduction method of a large amount of nursery stocks.

Purpose of the present invention is achieved by following technical proposals.

The invention provides a kind of slide plate dish cutting asexual reproduction method, this method adopts the step of following order:

(1) the perennial liana under the nature is adopted in cutting;

Remove the Lao Ye on the liana, stay leaf bud, by one section of per 2 leaf bud, bud respectively stays 3～5 centimetres outward up and down, shears cutting, keeps its upper-lower position, can not be inverted;

(2) top of every cutting is entangled with the plastic film wrapping or with plastic tube, expose the eye in the cutting during wrapping, the wrapping width is for transplanting a cutting 2/3rds of total length, and does not wrap up the cutting bottom, and per 100 root cuttings are bundled into 1;

(3) to put into weight concentration be that 3/1000ths commercially available root-inducing powder soup soaked 30 minutes in the lower end of the cutting that will tie;

(4) will insert the fine sand bed through the cutting that handled step (3), film portion is not pricked in the bottom of cutting, all inserts in the sand, the wrapping part is inserted 1～2 centimetre, and cutting density is 5 * 20 centimetres, keeps husky bed humidity, husky bed covers 75% shade net early stage, changes 50% shade net when germinateing into;

(5) begin to transplant during bud length to 9～11 centimetre, by normal cuttage seeding cultivation management.

Compared with prior art, the present invention has the following advantages:

Because this plant is a herbaceous species, when transplanting a cutting vegetative propagation with it, the easy dehydration of the first half of transplanting a cutting is withered, and withered because of top dehydration even after the latter half is taken root, can not germinate survives.Have not yet to see the slotting skewer asexual reproduction method of this plant.This method is simple, and cost is low, and the survival rate height can provide a large amount of high quality seedlings for the cultivation of slide plate dish.

Embodiment

By specific embodiment given below, can further be well understood to the present invention.But they are not limitation of the invention.

Embodiment 1

March, gather the perennial liana of wild slide plate dish.Cut off Lao Ye with secateurs,, keep 3～5 centimetres of angles on every joint by 2 every section joints (is the joint that germinates, and is the joint of taking root) clip cutting.The cutting that shears is wide with 2 centimetres, the film bundling of 15 centimeter length.Eye is exposed in wrapping cutting upper end 2/3rds, will tighten last end closure during wrapping up and down.Per 100 of the cutting that bandages is bundled into 1, puts into weight concentration and be 3/1000ths ABT2 root-inducing powder soup and soaked 30 minutes.Insert in husky bed then.Husky bed places 75% the cloudy canopy of shade net.Transplant a cutting and insert in the husky bed, the husky bed humidity 85% of not wrapping part.5 days long, began in 10 days to germinate, shade net density changes 50%, 30 day into transplants a cutting bud and grows into about 10 centimetres and transplant.

Embodiment 2

Repeat embodiment 1, following difference is arranged: gather the perennial liana of wild slide plate dish in May, entangle cutting top 2/3rds parts with the thin plastic tube of 5～8 millimeters of diameters, cut an osculum with scissors and expose eye at the eye place, and upper and lower end is tightened with rubber band.
