| Abstract: |
| In order to study the effects of different fertilization treatments on the growth of Elephantopus scaber
Linn. The main growth and yield indexes of Elephantopus scaber Linn under the treatments of biogas slurry fertilizer，
compound fertilizer and organic manure were compared with no fertilization treatment.The results showed that the
fertilization could effectively improve the growth and yield indexes of plant height，leaf number，leaf length and
width，root length，whole grass yield，root yield，root / shoot ratio，whole grass yield of three fertilization treatments，
Root production were higher than non-fertilizer treatment more than 1 times，from all the growth indicators of
comprehensive point of view，the growth of gentian mainly occurs in the peak from May to August，indicating that
fertilization is to promote the growth and yield of gentian directly Effective approach，the key period of fertilization
should be placed in May to August. The overall performance of biogas slurry treatment was better than compound
fertilizer treatment and organic fertilizer，indicating that under the same conditions，biogas slurry fertilizer was more
conducive to the growth of artificial cultivation of gall grass. |
