Below in conjunction with comparative trial, the invention will be further described.
Test example 1
From the arborvitae 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 12 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 arborvitae 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/% | 72.5 | 62.3 | 80.5 | 71.3 |
As shown in Table 1, adopt gloomy life to urge for No. 8 root agent 1500ppm to be urged root to process to arborvitae cuttage branch, yield rate reaches more than 80%, 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
.
