摘　　要：为明确不同根际生境对青甘韭生长发育的影响,以沙壤土(T_(1))、沙壤土∶发酵猪粪=1∶1(T_(2))、川滇高山栎凋落物(T_(3))、草炭(T_(4))4种根际环境处理,对多年生青甘韭抽薹开花期、形态特征、营养品质等指标进行测试分析。结果表明:不同根际生境对青甘韭抽薹开花期有明显影响,疏松透气、营养充足的根际生境有利于促进其提前抽薹开花;在不同根际生境下青甘韭对5种中微量矿质元素的吸收有不同程度差异,Ca、Fe、B、Se元素含量均是叶中高于地下茎而Zn元素含量则相反;蛋白质、粗纤维、叶绿素和类胡萝卜素含量及株高和叶长均在不同生境下表现出明显差异。In order to clarify the effects of different rhizosphere habitats on the growth and development of Allium przewalskianum Regel,four rhizosphere environments were treated with sandy loam soil(T_(1)),sandy loam soil:fermented pig manure=1∶1(T_(2)),oak litter of Quercus aquifolioides(T_(3)),and peat(T_(4))to treat the flowering period,morphological characteristics and nutritional quality of perennial A.przewalskianum were tested and analyzed.The results showed that different rhizosphere habitats had a significant impact on the flowering period of A.przewalskianum,and a loose,breathable,and nutrient rich rhizosphere habitat was conducive to promoting early flowering and bolting;There were varying degrees of differences in the absorption of five trace mineral elements by A.przewalskianum in different rhizosphere habitats.The content of Ca,Fe,B,and Se elements was higher in leaves than in underground stems,while the content of Zn elements was the opposite;Protein,crude fiber,chlorophyll and carotenoid content,as well as plant height and leaf length,all showed significant differences in different habitats.
