Description
Technical field
The invention belongs to the plant propagation technical field, be particularly related to Microbiota decussata cutting propagation method.
Background technology
The Russia cypress
microbiota decussata, Cupressaceae, Russian cypressCypressus, evergreen coniferous tree, the floor file brushwood, the shape of crawling extends expansion, and the bark sepia scales off; Height of tree 20.0cm-40.5cm, hat width 1.2m-1.8m, branch is short, slightly flat, soft, like feather, most advanced and sophisticated micro-sagging, with short and level and smooth verticillate pricker; Scale leaf is small, and nearly triangle is imbricate and arranges, spring green, summer, green turned dirty-green, partly transferred coppery autumn to, all became purple, bronze colour or bronzing to winter; Summer at florescence, female, male cone equal be born in the brachyplast top, female cone is avette, fruit scale 3-4 only can educate cone ellipse, sepia for 1.
Russia's cypress happiness light, but full exposure and partly shade under normal growths all, if but the illumination deficiency can cause branch excessive growth, too elongated, ornamental value decline.Like micro-acid, neutrality and alkalescence, be rich in organic loamy soil, must guard against ponding, require excessively drained field.Anti-strong frost, cold resistance is strong, and anti-crushing by snow ability is strong.Can do by, potted plant, edging plant, mountain region, slope plantation, basic material, for rock garden, rock garden, mixed border etc.
The Russia cypress originates in the ground such as Russia, the southeast, Siberia, be common in mountainous region's growth, for being distributed in the seeds more than timber line, multiplex planted in ground or bank slope is reinforced, it is good green plants, but at home or a brand-new kind, in China's cold district in winter, northeast, North China, southwest and subtropical zone, all can plant, there are wide market prospects.By the inquiry to data of literatures, current domestic scientific paper and the patent that Russian cypress Technique on Cuttage Propagation is relevant that there is no, it is blank that this field still belongs to.

Below in conjunction with comparative trial, the invention will be further described.
Test example 1
From Russian cypress female parent, take the autumn then slightly to be cut fringe, being cut into length is the cuttage branch of 6.0cm left and right, retains top, and lower cut is level and smooth, wipes out the needle of fringe bar bottom 2.0cm left and right, and leaf site 4.0cm left and right is stayed on top.The cuttage branch adopts four kinds of processing (as shown in table 1), each treatment samples given figure 600 strain.Adopt seedbed to carry out cuttage, the cuttage degree of depth is the 2.0cm left and right, the yield rate of each processing of " Invest, Then Investigate " in 10 months.The indolebutyric acid that wherein gloomy life is 6:2:2 by weight ratio No. 7: methyl α-naphthyl acetate: the ABT6 root-inducing powder mixes, and the indolebutyric acid that gloomy life is 4:2:2:2 by weight ratio No. 8: heteroauxin: methyl α-naphthyl acetate: the ABT1 root-inducing powder forms.
Table 1 plant is urged the impact of root agent on Russian cypress cottage propagation yield rate
| Test processing number | A | B | C | D |
| Plant is urged the root agent | No. 7, gloomy life | No. 7, gloomy life | No. 8, gloomy life | No. 8, gloomy life |
| Concentration/ppm | 1500 | 2500 | 1500 | 2500 |
| Yield rate/% | 73.2 | 81.5 | 80.3 | 90.3 |
As shown in Table 1, adopt gloomy life to urge for No. 8 root agent 2500ppm to be urged root to process to Russian cypress cuttage branch, yield rate reaches more than 90%, and result of use is significantly higher than other plant and urges the root agent.Gloomy life urges for No. 8 the root agent to adopt other concentration of the present invention and formula, carries out comparative trial, also can reach similar result of use.
Mesostroma quality of the present invention, the concentration of urging the root agent and formula difference, have remarkable impact to yield rate
.
