摘　　要：人工种植地胆草主要施肥技术是在定植1个月后撤施一定量的复合肥。为了研究不同施肥处理对人工栽培地胆草生长的影响,以不施肥处理为对照,比较分析了施用沼液肥、复合肥、有机肥几种处理下地胆草主要的生长及产量指标。试验结果:施肥可有效提高地胆草的株高、叶片数、叶片长宽、根长、全草产量、根头产量、根冠比等生长与产量指标,3个施肥处理的全草产量、根头产量均比不施肥处理的高1倍以上,从各个生长指标综合来看,地胆草生长高峰期主要出现在5~8月份。结果表明施肥是促进地胆草生长及产量提高的直接而有效的办法,施肥重点时期在5~8月份。施用沼液肥处理的整体表现优于复合肥处理和有机肥,说明在同等条件下,施用沼液肥更有利于人工栽培地胆草的生长。Effect of various fertilizers for the intercropped Elephantopus scaber Linn in forest on the growth performance of the grass was studied. Major growth and yield indices of the turf with or without the application of a biogas fertilizer, a compound fertilizer or organic manure were compared. The results showed that the fertilization one month after planting effectively increased the plant height, leaf count, leaf length, leaf width, root length, total yield, root yield, root/shoot ratio, and other growth and yield indices of the grass. It doubled the total yield as compared to control. Consequently, fertilization could be a direct and effective way to promote the growth and yield of E. scaber. The application was best implemented from May to August when the peak growth of the grass occurred. The biogas slurry appeared to perform better overall and was more conducive to the grass-intercropping than the other fertilizers tested.
