摘　　要：为了探究知母栽培过程中最佳施肥方式和施肥配比,采用产自河北省易县的一年生知母苗,移栽进花盆统一进行缓苗管理后进行肥料试验,研究不同肥料配比对知母株高、地上部和根部农艺性状的影响。结果表明:叶面喷施处理的肥料稀释浓度为200倍时,添加2.0 g·L^(-1)尿素+1.0 g·L^(-1)硫酸钾的混合溶液30.0 mL、氨基酸水溶肥7.5 mL及GGR 8号22.5~30.0 mL的使用效果最佳,具体表现为株高较高,叶片较宽较厚、数量较多、氮含量及SPAD值较高,叶片鲜重及叶片干重较重,根长较长,须根数量较多,须根鲜重及须根干重较重,折干率较高;灌根处理的肥料稀释1000倍时,添加20.0 g尿素+10.0 g K_(2)SO_(4)、氨基酸水溶肥10.0 mL及GGR 8号10.0~20.0 mL的使用效果最佳,总体来看,叶面喷施处理的使用效果相比灌根处理具有一定的优势。In order to explore the best fertilization method and ratio in the process of Anemarrhena asphodeloides cultivation,the annual Anemarrhena asphodeloides seedlings produced in Yi County,Hebei Province were transplanted into flower pots for unified slow seedling management,and then the fertilizer experiment was carried out to study the effects of different fertilizer ratios on the plant height,aboveground and root agronomic characteristics of Anemarrhena asphodeloides.The results showed that when the fertilizer dilution concentration of foliar spraying treatment was 200 times,the application effect was the best.When 30.0 mL of mixed solution of 2.0 g·L^(-1) urea+1.0 g·L^(-1) potassium sulfate,7.5 mL of amino acid water-soluble fertilizer and 22.5-30.0 mL of GGR 8 were added,which was characterized by higher plant height,wider and thicker leaves,more numbers nitrogen content and chlorophyll SPAD value was higher,the fresh weight and dry weight of leaves were heavier,the root length was longer,the number of fibrous roots was more,the fresh weight and dry weight of fibrous roots were heavier,and the drying rate was higher.When the dilution concentration of fertilizer for root irrigation treatment was 1000 times,the application effect of adding 20.0 g urea+10.0 g K_(2)SO_(4),10.0 mL amino acid water-soluble fertilizer and 10.0-20.0 mL GGR 8 was the best.In general,the application effect of foliar spraying treatment is better than that of foliar spraying treatment root irrigation treatment group,and had certain advantages.
