Abstract
A method for cuttage propagation of cupressocyparis leylandii 'Robertsons Gold' belongs to the technical field of plant propagation and includes steps: firstly, mixing pulverized reed leaves, vermiculite, pearlite, loess and organic fertilizer into cuttage matrix according to a volume ratio of 2-4:0.5-2:0.5-2:3-5:0.5-2; thirdly, cutting an annual semi-ligneous lateral branch to obtain a cutting from a female parent of cupressocyparis leylandii 'Robertsons Gold' at the cuttage time, late July; fourthly, dipping a base of the cutting in plant rooting agent Sensheng No.2 at the speed 100-300ppm for one to three seconds; performing cuttage on a seedling bed prior to management and maintenance; and sixthly, exercising seedlings on the fifty-fifth to the sixty-fifth day after cuttage when rooting rate reaches above 90%. By the method, rooting is good, and yield reaches above 90%. The method is simple and fast in propagating and applicable to climate and soil of China, and has great market outlook.
Description
Technical field
The invention belongs to the plant propagation technical field, be particularly related to weeping branch Japan cypress wood cuttage breeding method.
Background technology
Weeping branch Japan cypress wood
Cupressocyparis leylandii' Robertsons Gold ' is subordinate to the flat Cupressus of Cupressaceae, evergreen coniferous tree, arbor.The bark sepia, winter turns white in the surface, and height of tree 20-25m is healthy and strong, orthostatic is good; Tree crown steeple shape, hat width of cloth 5-8m; Branch red zone pricker has needle and scale leaf, and summer, golden yellow was main, and green, yellow green was clouded in branch and seemed soft as feather winter; Leaf is alternately to life.Not strict to the soil types requirement, can be at acidity, neutrality and the growth of alkalescence soil, happiness rich soil; Happiness full exposure condition is partly given shade also and can be grown; Drought-enduring slightly, salt tolerant alkali, antipollution can be made hedge through pruning, or be cut into moulding trees such as sphere, cylindricality, turriform, also can make gardens tree, landscape tree, soil and water conservation forest and wind break.
Weeping branch Japan cypress wood originates in Japan, and ornamental value is high, and wide accommodation all can be planted in China northeast, North China and subtropical zone, is widely used in hedge and shelter forest abroad, but still is a brand-new kind at home.Through inquiry to data of literatures, do not see domestic relevant scientific paper and the patent of weeping branch Japan cypress wood cottage propagation technology that have at present, this field still belongs to blank.
Summary of the invention
To the problems referred to above that exist in the prior art, the objective of the invention is to design the technical scheme that a kind of weeping branch Japan cypress wood cuttage breeding method is provided, it is simple to operate, reproduction speed is fast, and yield rate reaches 90%, has filled up the blank of correlative technology field.
Described weeping branch Japan cypress wood cuttage breeding method is characterized in that may further comprise the steps:
1) selects subacidity, neutrality and alkalescence soil; The place that draining well has a good transport service; Set up the maternal district of weeping branch Japan cypress wood cutting orchard, setting up shading rate is the sunshade net of 60-70%, and the cutting orchard seeding row spacing of planting is 40cm * 40cm; Density is 2400-2600 strain/mu, and female parent highly remains on 30-40cm;
2) matrix is puddled evenly; Be filled in the dish of 72 holes, keep the matrix elasticity consistent, with the cave dish that fills matrix; Put successively on the seedbed; Put 5-7 only for every square metre, carry out disinfection with 700-900 times of liquor potassic permanganate preceding 24 hours of cuttage, described matrix is the reed jasmine of 2-4:0.5-2:0.5-2:3-5:0.5-2 by volume ratio: vermiculite: perlite: yellow soil: fertilizer mixes and constitutes;
3) cutting time is late July; Cuttage in 1 year 1 time is taked to give birth to the semi-lignified side shoot then and is cut fringe from weeping branch Japan cypress wood female parent, being cut into length is the cuttage branch of 6.0-8.0cm; Keep the top; Lower cut is level and smooth, wipes out the needle of fringe bar bottom 1.5-2.0cm, and leaf site 4.0-6.0cm is stayed on top;
4) the cuttage branch adopts No. 2 plants of gloomy life to urge root agent 100-300ppm dipping fringe bar base portion 1-3 second, and it is the indolebutyric acid of 5-7:1-3:1-3 by weight ratio that No. 2 plants of described gloomy life are urged the root agent: heteroauxin: the ABT6 root-inducing powder mixes formation;

Below in conjunction with comparative trial the present invention is described further.
Test 1:
From weeping branch Japan cypress wood female parent, take to give birth to the semi-lignified side shoot then and cut fringe, being cut into length is the cuttage branch about 7.0cm, keeps the top, and lower cut is level and smooth, wipes out the needle about fringe bar bottom 2.0cm, and top is stayed about leaf site 5.0cm.The cuttage branch adopts four kinds of processing (as shown in table 1), each treatment samples given figure 600 strain.Adopt 72 holes dish to carry out cuttage, the cuttage degree of depth is about 2.0cm, the yield rate of each processing of " Invest, Then Investigate " in 8 months.In this test No. 2 plants of gloomy life to urge the root agent be the indolebutyric acid of 6:2:2 by weight ratio: heteroauxin: the ABT6 root-inducing powder mixes and constitutes; It is the methyl of 5:2:3 by weight ratio that No. 5 plants of described gloomy life are urged the root agent: GA4 gibberellin: the ABT6 root-inducing powder mixes formation.No. 2 plants of gloomy life urge root agent, No. 5 plants of gloomy life to urge the root agent to be buied by Senhe Seed Industry Co., Ltd., Zhejiang Pror..
Table 1 plant is urged the influence of root agent to weeping branch Japan cypress wood cottage propagation yield rate
| Test is handled number | A | B | C | D |
| Plant is urged the root agent | No. 2, gloomy life | No. 2, gloomy life | No. 5, gloomy life | No. 5, gloomy life |
| Concentration/ppm | 200 | 500 | 200 | 500 |
| Yield rate/% | 90.8 | 83.5 | 76.2 | 59.1 |
Can be known that by table 1 No. 2 plants of gloomy life that are treated to of the most suitable cottage propagation weeping branch Japan cypress wood are urged 2 seconds of root agent 200ppm dipping fringe bar base portion, adopt this processing yield rate to reach 90.8%, result of use is significantly higher than other plant and urges the root agent.No. 2 plants of gloomy life urge the root agent to adopt other concentration of the present invention and prescription, compare test, also can reach similar result of use.
Mesostroma composition of the present invention and quality, urge the concentration of root agent and prescription different, yield rate is all had appreciable impact.
