Table 1 plant urges the root agent on the impact of blue Pacific Ocean bank Chinese juniper cottage propagation yield rate
| Test is processed 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/% | 71.2 | 58.4 | 80.1 | 72.3 |
As shown in Table 1, the most suitable cottage propagation blue Pacific Ocean bank Chinese juniper urge the root agent to be treated to No. 3 plants of gloomy life urging root agent 200ppm, adopt this processing yield rate can reach more than 80%, result of use is significantly higher than other plant and urges the root agent.Gloomy life urges for No. 3 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.
