Abstract

A conventional tree branch dormancy stage cuttage is not suitable for wintersweet, and thus, the breeding of the wintersweet is not dependent on other methods besides cuttage. Thus, the breeding speed and cost of the fine wintersweet is limited. The present invention provides a method of the cuttage of the wintersweet by sealing the end of the wintersweet with wax. The survival rate of the dormancy stage cuttage of the wintersweet reaches more than 95% by measures, such as the wax seal of the upper part of a branch, long lopping, the longitudinal bark cut of the lower part of the branch, flower bud removal, etc. according to the specific physiological characteristics of the wintersweet.

Description

Method of cuttage of wintersweet by sealing its end with wax

One, technical field

The present invention relates to the wintersweet culture technique, particularly relate to a kind of wintersweet by sealing its end with wax cuttage technique.

Two, background technology

Present known wintersweet propagation technique has seeding method, grafting, the planting of layer and tissue culture method, and wherein the shortcoming of first three kind is that the cycle is long, and reproduction speed is slow, and the latter's shortcoming is that equipment investment is many, specification requirement is high.As everyone knows, have cuttage only and have that small investment, cycle are short, specification requirement is not high, the advantage that reproduction speed is fast, yet people are through repeatedly practising, find that wintersweet can not survive by the normal cutting propagation method, even can sprout a little spray after the cuttage of part wintersweet, die but finally still can dry up.

Three, summary of the invention

The objective of the invention is provides a kind of method of cuttage of wintersweet by sealing its end with wax to society, to solve the cuttage difficult problem of breeding wintersweet.

The object of the present invention is achieved like this: carry out cuttage during the January of October to next year, because there is early blossoming in wintersweet, the breed difference that middle flower and evening are spent, so the selection on cuttage opportunity should begin to expand with the wintersweet bud, clip branch when the bud center begins yellowing, branch length is controlled at 40-45cm, after removing whole remaining blades and whole bud, certainly vertically ream a skin apart from branch lower end 15 centimeters to termination, lower end with cutter, the width of cutting mouth exposes wooden degree of being to cut a mouthful center line, hold the branch lower end then temperature is inserted straight down in 120 ℃-130 ℃ paraffin molten in branch top, the time that branch stops in paraffin molten can not be above one second, the submergence of branch in paraffin molten is controlled at 12-15cm, during cuttage, ditch depth is got 25-30cm, ditch is apart from 20-25cm, the center line angle of branch and ditch is got 50 °-70 °, vertically cutting mouthful downwards of branch bottom, branch is got 8-10cm at interval, after burying soil, make branch top expose face of land 10-12cm, the area that frost is heavy must cover the tangerine bar on the face of land, make surface temperature be not less than-10 ℃, when face of land temperature still is higher than-10 ℃ under the situation that no tangerine bar covers, then in time remove covering, to branch survive after autumn then, the yellowing of wintersweet blade trips out transplanting on the cuttage plant to next year rudiment in spring.

Owing to adopt such scheme, can receive following remarkable result:

1, Chang Gui resting stage cuttage all is that the branch upper end is directly exposed in air, because wintersweet branch dehydration especially easily, and the sprouting of wintersweet requires that enough moisture content is arranged in the branch, this is the one of the main reasons that routine resting stage skewer method is unsuitable for wintersweet, and this programme has sealed up one deck wax for branch top, thereby can reduce more than 90% of branch top evaporation discharge, this is to facilitate one of major reason that wintersweet cuttage branch survives.

2, because the normal cutting propagation method is ignored the bud that removes on the branch, hardly realize, the existence of these buds will exhaust the nutrition of storing in the branch, after waiting to bloom, the unable sprouting of branch sprouting, this programme has then removed whole buds in good time, makes the nutrition that is stored in the branch can all be used for the sprouting of sprouting.

3, since the normal cutting propagation method when shearing branch, skin separated with the wooden part that produced when the lower end of branch was pressed because of cutting, the wintersweet branch end difficulty of just taking root originally in addition, so just more aggravated the seriousness of this problem, and this programme vertically cuts away a skin in the branch bottom, because otch is smooth, very help wound self-healing, and in self-healing both for new root give birth to and to have laid organization foundation, provide very broad root again and give birth to the space, also strengthened the water absorbing capacity of branch greatly.

4, the length of normal cutting propagation method branch all obtains very short, generally at 15-25cm, branch is too short under ground portion like this, cause the area that absorbs moisture content too little, this is extremely incompatible to wintersweet, and this programme has increased nearly one times with the length of branch than conventional method, and this had both made its under ground portion water absorbing capacity strengthen, and the nutrient of storing in the branch is increased greatly.

5, because the sprouting of wintersweet sprouting is very responsive to the distribution of auxin concentration, this programme is through test, when branch becomes 60 ° of left and right sides with the ground angle, the rudiment effect is best, and rudiment concentrates on 1-2 bud near branch upper end, and this just makes the nutrition of rudiment concentrated, robust growth.

6, owing to adopt such scheme, the survival rate of resting stage cuttage that makes wintersweet is up to more than 95%.

Claims

1, a kind of method of cuttage of wintersweet by sealing its end with wax, it is characterized in that: during the January of October to next year, carry out cuttage, the selection on concrete cuttage opportunity begins to expand with the wintersweet bud, clip branch when the bud center begins yellowing, branch length is controlled at 40-45cm, after removing whole remaining blades and whole bud, certainly vertically ream a skin apart from branch lower end 15 centimeters to termination, lower end with cutter, the width of cutting mouth exposes wooden degree of being to cut a mouthful center line, hold the branch lower end then temperature is inserted straight down in 120 ℃-130 ℃ paraffin molten in branch top, the time that branch stops in paraffin molten is no more than one second, the submergence of branch in paraffin molten is controlled at 12-15cm, during cuttage, ditch depth is got 25-30cm, ditch is apart from 20-25cm, the center line angle of branch and ditch is got 50 °-70 °, vertically cutting mouthful downwards of branch bottom, branch is got 8-10cm at interval, after burying soil, make branch top expose face of land 10-12cm, the area that frost is heavy must cover the tangerine bar on the face of land, make surface temperature be not less than-10 ℃, when face of land temperature still is higher than-10 ℃ under the situation that no tangerine bar covers, then in time remove covering, to branch survive after autumn then, the wintersweet blade yellowing on the cuttage plant trips out transplanting to next year rudiment in spring.
