Below in conjunction with comparative trial the present invention is described further.
Test Example 1
From the Chinese juniper female parent of Gold Coast, take the autumn of last one year to cut fringe slightly, being cut into length is the cuttage branch about 6.0cm, 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 4.0cm.The cuttage branch adopts four kinds of processing (as shown in table 1), each treatment samples given figure 600 strain.Adopt the seedbed to carry out cuttage, the cuttage degree of depth is about 2.0cm, the yield rate of each processing of " Invest, Then Investigate " in 10 months.Wherein gloomy life is the indolebutyric acid of 6:2:2 by weight ratio No. 2: heteroauxin: the ABT6 root-inducing powder mixes formation, and gloomy life is No. 6 two gill GGR root-inducing powders of 6:2:2 by weight ratio No. 3: methyl: the ABT1 root-inducing powder constitutes.
Table 1 plant is urged the influence of root agent to Gold Coast Chinese juniper 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. 3, gloomy life | No. 3, gloomy life |
| Concentration/ppm | 200 | 500 | 200 | 500 |
| Yield rate/% | 85.3 | 71.5 | 73.5 | 67.3 |
Can be known that by table 1 adopt gloomy life to urge for No. 2 root agent 200ppm to urge root to handle to arborvitae cuttage branch, yield rate reaches more than 85%, result of use is significantly higher than other plant and urges the root agent.Gloomy life urges for No. 2 the root agent to adopt other concentration of the present invention and prescription, compares test, also can reach similar result of use.
Mesostroma quality of the present invention, the concentration of urging the root agent and prescription difference all have appreciable impact
to yield rate.
