摘要 该研究以多年生不同产地药用芍药品种资源为研究对象,通过观察和记录芍药在甘肃河西冷凉地区生长的物候期及植物学特性与生长发育习性,测定芍药返青后不同生长期营养元素和药效成分含量,并在此基础上选出适合本地引进栽培的优良品种,探究不同产地芍药种质资源在甘肃河西冷凉地区引种栽培试验对比分析及生物学特性与发展现状,丰富本地的药用芍药品种资源;促进本地区药用芍药产业的可持续发展。通过对不同产地药用芍药营养元素吸收、光合特性分析等生理指标变化的影响,明确影响药效成分积累的营养元素种类,从而为科学地制定药用芍药规范化种植与肥料配方提供理论依据,为提高药用芍药药材品质与产量提供新思路。 In this study,perennial medicinal peony variety resources of different producing areas were taken as the research object.By observing and recording the phenological period,botanical characteristics and growth and development habits of Peony growing in cold and cool areas of Gansu Province,the nutritional elements and pharmacodynamic components contents of peony in different growth stages after greening were determined,and on this basis,excellent varieties suitable for local introduction and cultivation were selected.To explore the comparative analysis,biological characteristics and development status of different Paeonia germplasm resources introduced and cultivated in cold and cool area of Hexi,Gansu Province,and enrich the local medicinal Paeonia germplasm resources.To promote the sustainable development of the pharmaceutical peony industry in this region.The changes of physiological indicators such as nutrient element absorption and photosynthetic characteristics analysis of the medicinal peony in different producing areas were investigated,and the types of nutrient elements affecting the accumulation of medicinal components were clarified,thus providing theoretical basis for the scientific formulation of standardized planting and fertilizer formula of the medicinal peony,and providing new ideas for improving the quality and yield of the medicinal peony.
