Abstract

The invention discloses a kind of beautiful asexual reproduction method had a smile on one's face propagation by grafiting method, belong to plant, the method comprises the following steps:(1) grafting time;(2) prepared by stock;(3) scion is chosen;(4) grafting;(5) managed after connecing.The present invention can keep beautiful view and admire with a smile to wait good characteristic by force with winter resistance, and survival rate improves 20 30% compared with spring grafting;Because the end of spring and the beginning of summer arboreal growth is vigorous, resin mobility is strong, and the grafting speed of growth is fast, strong adaptability.Therefore, this method compensate for the defects of spring grafting survival rate is low, slow-growing.

Description

A kind of beautiful propagation by grafiting method with a smile
Technical field
The present invention relates to a kind of xylophyta asexual reproduction method, is specifically related to beautiful propagation by grafiting method with a smile.
Background technology
It is beautiful to have a smile on one's face (Michelia maudiae ' jinxiu '), Magnoliaceae Michelia, aiphyllium.It is by Jiangsu Province woods The variation individual plant that grows directly from seeds of industry research institute seed selection from Michelia maudiae, has trunk logical straight, side shoot is open and flat, and early spring white flower is expired Tree, seed are red, oblique oval, and growth is rapid, the winter resistance specificity such as by force.Its tree-shaped is attractive in appearance, spends big fragrance, there is higher sight Reward and economic value, the kind obtain State Administration of Forestry's New species right in plant certificate in September, 2011.It is beautiful with a smile can be by transferring Connect or cuttage mode is bred, grafting is typically carried out when spring, trees sprouted, but spring is easily by the shadow of the meteorologic factors such as cold spell in later spring Ring, cause graft survival rate relatively low;Cutting propagation rootage duration is grown, and rooting rate is relatively low, and transplanting is difficult to survive and slow-growing.This Method is to use beautiful semi-lignified branch grafting with a smile summer, and by the selection of grafting time, stock is carved wound and discharged water, scion The technical measures such as shade bag cooling, moisturizing are applied mechanically, survival rate improves 20%-30% compared with spring grafting;Due to the end of spring and the beginning of summer trees Grow vigorous, resin mobility is strong, and the grafting speed of growth is fast, strong adaptability.Therefore, this method compensate for spring grafting and survive The defects of rate is low, slow-growing.
The content of the invention
Goal of the invention:The beautiful propagation method for viewing and admiring breeding with a smile can be kept it is an object of the invention to provide a kind of.
Technical scheme:To achieve the above object, a kind of beautiful engrafting method with a smile of the invention, it is characterized in that it is by following Step forms:
(1) grafting time:Mid-June to late June;
(2) prepared by stock:Stock is made with 2 years 2~3cm of dried rhizome of rehmannia footpath yulan, will be cut at the liftoff 20~40cm of stock, anvil 4-8 pieces leaf is stayed for manufacturing nutrient in wooden bottom, and stock rhizosphere portion is carved into 2~3 knives of wound, as deep as xylem, is hindered beneficial to resin by carving Flow out at position;
(3) scion is chosen:Avoid rainy day and the noon of hot weather, breeding it is beautiful with a smile elite stand middle and upper part to Yang Chu, the semi-lignified branch of giving birth to then that clip development is healthy and strong, leaf bud is full make scion, branch bottom are immersed in the water or with wet Cloth is wrapped, and scion is made every effort to adopting with connecing, and scion is cut into the stem section of 4~5cm length tool buds of 1 leaf 1, and it is short two that scion lower end is whittled into 1 length 1 Bevel, long face ream 1/3 xylem, and length is 2.5~3.0cm, and the shape of a hoof that 1.0cm or so is cut on the opposite of long face small is cut Face, the knife of 1.5cm or so straight snips one above away from bud, 1/2 blade is cut off, what the same day can not connect, which should be placed in 4 DEG C of refrigerators, refrigerates;
(4) grafting:Cross section central vertical rip cutting is cut as deep as 3.0~3.5cm in stock, will cut the scion that shears immediately Insertion stock splits mouth, make both both sides or the alignment of one side forming layer tie up it is tight, with plastic strip by junction surface together with cutting in scion Mouth is all tied up sternly, is exposed blade and leaf bud, is then inserted in black shading paper bag in length × wide=22cm × 18cm in grafting part, enters Row shade cooling processing;
(5) managed after connecing:Keep nursery lot ground moistening;After 1 week check survive, it is all budder it is bud green, petiole one touch be to fall As survive, the rudiment erased in time on stock, promote growing for scion, can be lightened restrictions on after interface healing completely;Strengthen Water and fertilizer management, pest and disease damage is prevented and treated in time;When scion young sprout length to 30cm or so, lush shield need to be inserted and tied up, prevent windbreak;Grafting survival Rate is up to 83.6~92.7%.
Beneficial effect:It can make up that spring grafting survival rate is low, growth is slow using grafting seedlings-growing method of the present invention The defects of slow, 20~30% are improved compared with spring grafting survival rate.The grafting speed of growth is fast, strong adaptability.Beautiful summer with a smile The stock of grafting and scion are tender and crisp, cut anvil and cut that scion etc. is easy to operate quick, and propagation by grafiting efficiency improves more than 50%, reduce The cost of beautiful vegetative propagation with a smile.
