摘　　要：为探究施肥处理对长白山区林下仿生栽培茖葱(Allium victoralis L.)物质积累与产量变化的影响,以长白山区敦化宽叶型茖葱植株为试验材料,对林下仿生栽培茖葱在不同氮磷钾施肥处理组合下的生物量、营养物质含量与产量差异进行了分析。结果表明,施肥处理能够在一定程度上促进林下仿生栽培茖葱植株各部分的生物量与营养物质积累。T4处理(即N 150 kg·hm^(-2),P2O575 kg·hm^(-2),K2O 150 kg·hm^(-2))有效地促进了林下仿生栽培茖葱植株各部分生物量,尤其是叶片生物量的积累,其叶片干质量最终比CK处理增加了28.57%。此外,T4处理下的维生素C、可溶性糖、可溶性蛋白含量与产量均高于其他处理,分别比CK处理增加了26.91%、40.47%、18.56%与42.82%。综上所述,对长白山区茖葱林下仿生栽培最有效的施肥处理为T4处理,其氮磷钾施用量分别为150、75、150 kg·hm^(-2)。In order to explore the influence of different fertilization treatments on substance accumulation and yield changes of the bionic cultivated Allium victoralis L.in forest from the Changbai Mountains,the Dunhua broadleaf type A.victoralis plants from the Changbai Mountains,Jilin province were selected as test materials.The biomasses,nutrient contents and yields of the bionic cultivated A.victoralis plants under forest under different N,P,K fertilization treatments were analyzed.The results showed that fertilization treatments can promote biomass and nutrient accumulation of the bionic cultivated A.victoralis in forest to a certain extent.The biomass accumulations,especially the leaf biomass accumulations of the bionic cultivated A.victoralis plants in forest were effectively promoted under T4 treatment(N 150 kg∙hm^(-2),P2O575 kg∙hm^(-2),K2O 150 kg∙hm^(-2)).The leaf dry weight under T4 treatment was 28.57%higher than CK treatment.The contents of vitamin C,soluble sugar,soluble protein and yield under T4 treatment were also higher than the other treatments,which were increased by 26.91%,40.47%,18.56%and 42.82%than CK treatment,respectively.In conclusion,the most effective fertilization treatment for the bionic cultivated A.victoralis in forest in the Changbai Mountains was T4 treatment,the N,P and K content was 150 kg∙hm^(-2),75 kg∙hm^(-2),and 150 kg∙hm^(-2),respectively.
