摘要： 为了研究不同施肥量对黄芪生长发育、药材产量及种子产量质量的影响，以甘肃省漳县种植的药用植物黄芪为材料，比较了2 种不同比例(N:P:K=1.25:3:1、N:P:K=2:3:1)下的6 种施肥处理(A1、A2、A3、B1、B2、B3)对黄芪生长状况（株高、分枝数、根长、根直径、地上部分鲜重、地上部分干重、根鲜重和根干重）、药材产量、种子产量与质量的影响。研究结果表明：不同时期各施肥处理对黄芪的影响不同，其中以生育中期影响最大；在不同施肥量处理下，A2 处理有利于提高黄芪药材产量，根鲜重、根干重产量最高；A3 处理种子产量最高；N:P:K=1.25:3:1 处理较N:P:K=2:3:1 处理黄芪种子产量高，并且种子的相对质量也有提高。A2处理有利于提高黄芪药材产量；A3处理有利于提高黄芪种子产量。

Abstract: In order to study different fertilization amount for the effect of astragalus root growth and development, medicinal material Output and seed yield and quality, Medicinal plant Astragalus of planting in gansu province Zhangxian regard as materials. Six different fertilization treatments(A1、A2、A3、B1、B2、B3) for the effect of growth status of astragalus(plant height, branch number, root length, root diameter, fresh weight on the ground, dry weight on the ground, root fresh weight and root dry weight), medicinal material Output and seed yield and quality are compared in 2 different proportions(N:P:K=1.25:3:1、N:P:K=2:3:1). Research results show that: the effect of different fertilization treatments on Astragalus root is different, which the greatest impact is the mid growth; under different fertilization treatments, A2 treatment is advantaged to improve the yield of Astragalus root, at the same time, root fresh weight and root dry weight yield are the highest; A3 treatment have the highest seed yield; Treatment of N:P:K=1.25:3:1 of Astragalus seed production is higher than treatment of N:P:K=2:3:1, and the relative quality of the seed is also improved. A2 treatment is beneficial to improve the yield of Astragalus; while A3 treatment is beneficial to improve the yield of Astragalus seed.
