摘　　要：为了给黄芪专用肥的推广应用提供依据,在甘肃省黄芪主产区陇西县、渭源县、岷县研究了含腐植酸高塔熔体黄芪专用肥与常规施肥对黄芪根部形态特征、产量、品质和经济效益的影响。结果表明,在减少化肥(纯养分)投入23.9%的条件下,施用含腐植酸高塔熔体黄芪专用肥(N-P;O;-K;O为20-26-8)1 200 kg/hm;较常规施尿素600 kg/hm;、磷酸二铵900 kg/hm;可使黄芪干根长增加1.28%~3.80%、干根直径增加19.51%~26.97%、干根重增加15.55%~17.33%,产量增加10.46%~15.49%,甲苷含量增加0.031~0.112百分点,毛蕊异黄酮葡萄糖苷含量增加0.012~0.015百分点。纯收益增加14 193~18 862元/hm;。The purpose of this study is to provide a basis for the promotion and application of Astragalus special fertilizer,the effects of special fertilizer and conventional fertilization on the root morphology,yield,quality and economic benefit of Astragalus membranaceus were studied in Longxi county,Weiyuan county and Min county,the main cultivation areas of Astragalus in Gansu province. The results showed that the dry root length,diameter and weight of Astragalus membranaceus were increased by1.28% ~3.80%,19.51% ~26.97% and 15.55% ~17.33%,respectively,the yield improved by 10.46% ~15.49%,the content of methyl glucoside and isoflavone glucoside in pistil enhanced by 0.031%~0.112%,and 0.012%~0.015%,respectively,and the net income increased by 14 193~18 862 yuan/hm;,under the condition of reducing the input of chemical fertilizer(pure nutrient)by23.9%,the application of special fertilizer(N-P;O;-K;O was 20-26-8)1 200 kg/hm;for Astragalus membranaceus containing humic acid high tower melt compared with conventional fertilizer(urea 600 kg/hm;,diammonium 900 kg/hm;).
