| 摘 要： | 按照海拔、地形和地貌条件的不同 ,各选取 666.67m2 试验样地 ,统一按照 2 0cm× 2 0cm( 2 5 .0 5万株 /hm2 )株行距设计 ,栽种同一育苗基地同龄种苗 ,统一田间管理技术进行栽培试验 ,收获期统一测定黄芪甲甙含量。研究结果表明 ,不同地区黄芪甲甙含量变化较大 ,差异高达 2 .4倍 ;山地非灌溉地区黄芪甲甙含量最低 ,次为坡地 ,川地灌溉地区最高。因此 ,陇西地区黄芪人工栽培基地应当主要选择在川地及坡地地区种植 (海拔 2 10 0m以下地区 )。

| Abstract: | According to the various elevations and geographical differences, each selection of 666.67 m 2 to plant 25.05 ten thousand plants/(hm 2) of Astragalus membranaceus with 20*!cm×20*!cm between individual plant and line design was applied. Unified seedling age and field management techniques were used for cultivation, fertilization and weeding. Results indicated that contents of astragaloside Ⅳ in the Astragalus membranaceus grew in different regions varied greatly. The plants grown at the mountainous region without irrigation produced the lowest amount followed by plants grown at hillside fields with irrigation, and the plants grown at plain ground with irrigation gave the highest content.Astragaloside Ⅳ of Astragalus membranaceus grown at different regions varied greatly as high as 2.4 times. Therefore,selecting the sites as cultivation base for planting Astragalus membranaceus should mainly choose the plain ground and sloping fields at elevation below 2100 m. |
