Abstract

The invention belongs to the technical field of plant propagation and particularly discloses a cuttage propagation method for Juniperus chinensis 'Plumosa Aurea'. The method comprises the following steps of: 1) uniformly mixing imported peat, coconut tree branny, vermiculite and pearlite in a volume ratio of (2-4):(3-5):(1-3):(0.5-2) which are taken as matrixes, and filling into a 72-hole plug; 2) picking lateral branches of female parents and cutting spikes in early March; 3) impregnating ear bases of cuttage branches for 2 seconds by using a Sensheng No.6 plant root promoter at the concentration of between 1,400 and 1,600ppm; 4) building an arch shed, and covering by using a plastic film; and 5) uncovering the film when the rooting rate reaches about 95 percent on the 95th day after cuttage, namely uncovering the film at both ends of the arch shed first and ventilating, and uncovering the entire film after 2 days and performing full exposure hardening. By the cuttage propagation method for the Juniperus chinensis 'Plumosa Aurea', the rooting condition is good, and the yield reaches over 95 percent; and the method is high in propagation speed, can adapt to climate and soil environments in China, and has good market prospect, and the propagation operation steps are simple.

Description

Gold feather juniper cuttage breeding method

Technical field

The invention belongs to the plant propagation technical field, be specially a kind of golden feather juniper cuttage breeding method.

Background technology

' golden feather ' juniper Juniperus chinensis' Plumosa Aurea ' is subordinate to the Cupressaceae juniper and belongs to, evergreen coniferous tree, and shrub, branch is intensive, and branch is strong and powerful, arch expansion, height of tree 3-4m, hat width 2.5-4m; Needle and scale leaf are arranged, and Ye Sezai is yellow green spring to autumn, transfer bronze colour and yellow to winter, and tree crown is inner green; Cone berry shape, green and brown look.

' golden feather ' juniper happiness light is heat-resisting, drought-enduring, anti-air pollution, happiness draining good soil be must guard against ponding, can do by or hedge, be widely used in abroad the urban afforestation plantation, its ornamental value is high, wide accommodation but at home or a brand-new kind,, all can plant in China northeast, North China, southwest and subtropical zone, market prospects are wide.By the inquiry to data of literatures, have no at present domestic have golden feather juniper Technique on Cuttage Propagation relevant scientific paper and patent, it is blank that this field still belongs to.

Summary of the invention

For the above-mentioned problems in the prior art, the object of the invention is to design the technical scheme that a kind of golden feather juniper cuttage breeding method is provided, it is simple to operate, reproduction speed is fast, and yield rate reaches more than 95%.

Described golden feather juniper cuttage breeding method is characterized in that comprising the following steps:

1) be the import peat of 2-4:3-5:1-3:0.5-2 with volume ratio: coconut palm chaff: vermiculite: perlite is as matrix, puddle evenly, be filled in 72 hole dishes, keep the matrix elasticity consistent, the cave dish of matrix will be filled, put successively on the seedbed, put 6 for every square metre, carry out disinfection with 900 times of liquor potassic permanganates;

2) cutting time is early March, takes maternal side shoot to cut fringe, and cuttings length is 6.0cm, wipes out the needle of fringe bar bottom 2cm, and leaf site 4cm is stayed on top;

3) the cuttage branch adopts No. 6 plants of gloomy life to urge 2 seconds of root agent 1400-1600ppm dipping fringe bar base portion, adopt the seedbed cuttage, cuttage degree of depth 2.0cm, cuttage is complete, water immediately permeable, after dried on the blade face, to the carbendazim of 900 times of liquid of foliage spray and the U.S. mixed liquor of anthrax good fortune, the weight ratio of carbendazim and anthrax good fortune U.S. was 5-6:5-6;

4) take shed, cover with plastic film, the surrounding sealing keeps relative moisture 95% left and right in shed;

5) cuttage was in time watered in 10 days afterwards, made water content of substrate reach 60-70%, and in canopy, relative air humidity more than 95%, watered 1 time every 15 days later on; Summer and autumn, control the interior temperature of canopy below 36 ℃, during excess Temperature, canopy carries out mist cooling outward; After cuttage, before root of hair and germination, all will shade, shading rate reaches 75%;

After cuttage 95 days, when reaching 95% left and right, rooting rate removes film, and first open shed two film and ventilate, all removed afterwards film in 2 days and carry out full exposure and take exercise.

Table 1 plant urges the root agent on the impact of gold juniper cottage propagation yield rate

Test is processed number	A	B	C	D
					Plant is urged the root agent	No. 5, gloomy life	No. 5, gloomy life	No. 6, gloomy life	No. 6, gloomy life
Concentration/ppm	500	1500	500	1500
					Yield rate/%	78.1	84.5	86.4	95.2

As shown in Table 1, the most suitable cottage propagation gold feather juniper urge the root agent to be treated to " No. 6, gloomy life " plant urging root agent 1500ppm, adopt this processing yield rate can reach more than 95%, result of use is significantly higher than other plant and urges the root agent.Gloomy life urges for No. 6 the root agent to adopt other concentration of the present invention and formula, compares test, also can reach similar result of use.

Mesostroma quality of the present invention, the concentration of urging the root agent and formula difference have appreciable impact to yield rate.
