Abstract
The invention belongs to the technical field of the plant propagation, and particularly relates to a creeping juniper cutting propagation method, which comprises the following steps that: 1) a propagating land is selected to establish a creeping juniper mother specimen cutting orchard; 2) made-in-China turf, imported turf, vermiculite and perlite with volume ratio of 2 to 4: 2 to 4: 2 to 4: 0.5 to 2 are adopted as matrix to be uniformly blended and to be filled into a 72-pore tray; 3) the cutting time is the first third of March, a tip of the previous autumn branch on each side branch is collected from a mother specimen side branch to be cut; 4) basic parts of the cutting branches are dipped in 150 to 250ppm of Sensheng No. 6 plant root promoting agent for 2 seconds; 5) an arch shed is built and is covered by a plastic film; and 6) domestication is performed when the rooting rate reaches more than 85 percent in 120 days after the cottage, adequate light radiation exercise is performed by completely removing the film after 2 days. With the creeping juniper cutting propagation method, the rooting situation is good, and the rate of finished product can reach more than 85 percent. The propagation with the method is simple to operate, the method can adapt to the climate soil environment in China, and good market prospect can be realized.
Description
Technical field
The invention belongs to the plant propagation technical field, be specially a kind of cypress cuttage breeding method of laying down.
Background technology
The cypress of laying down
Juniperus chinensis var.Sargentii
,Be subordinate to the Cupressaceae juniper and belong to, evergreen coniferous tree, floor file brushwood.Height of tree 0.5m-0.8m, hat width 2.5m-3.0m; The twig arch crawls to expand, and covers with pricker; Scale leaf and needle are arranged, distribute in the shape of a spiral, celadon, level is tight, gives abundant sensation, and rubbing broken blade can give out a sweet perfume; Cone drupe shape, blue-green is covered with white powder.Happiness illumination is sufficient, and is drought-enduring, and the happiness draining is good, subacidity, neutrality and alkalescence soil, and growing way is medium, is planted with being mainly used in, also can make rock plant and potted landscape.
The cypress ornamental value of laying down is high, and wide accommodation all can be planted in China northeast, North China, southwest and subtropical zone; Multiplexly abroad do ground cover plant, be good urban afforestation seeds, but not yet developed at home to have wide market prospects.By the inquiry to data of literatures, have no at present domestic have lay down cypress 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 cypress cuttage breeding method of laying down is provided, it is simple to operate, reproduction speed is fast, and yield rate reaches more than 90%.
The described cypress cuttage breeding method of laying down is characterized in that comprising the following steps:

Test 1: the cuttage branch adopts four kinds of processing (as shown in table 1), each treatment samples given figure 600 strain.Adopt the seedbed cuttage, the cuttage degree of depth is 2.0cm, 12 months each processing yield rates of " Invest, Then Investigate ".In this test, gloomy life is for No. 6 the methyl α-naphthyl acetate of 4:4:2 by weight ratio: No. 6 two gill GGR root-inducing powders: the ABT1 root-inducing powder consists of, and gloomy life is for No. 5 the methyl α-naphthyl acetate of 5:2:3 by weight ratio: GA4 gibberellin: the ABT6 root-inducing powder consists of.No. 6 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 urges the root agent on the impact of the cypress cottage propagation yield rate of laying down
| 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 | 200 | 500 | 200 | 500 |
| Yield rate/% | 67.5 | 76.3 | 85.4 | 75.1 |
As shown in Table 1, the most suitable cottage propagation lay down cypress urge the root agent to be treated to " No. 6, gloomy life " plant urging root agent 200ppm, adopt this processing yield rate to reach more than 85%, 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.
