摘要
为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。结果显示,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,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,施肥重点时期应该放在5~8月。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。
In order to study the effects of different fertilization treatments on the growth of Elephantopus scaberLinn. 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.
