摘　　要：【目的】为探索宁夏中部干旱带黄花菜最佳的移栽密度,本文分析了移栽密度调控对黄花菜产量及品质的影响,为提高黄花菜产量和品质以及种植初期土地利用率和经济效益提供技术支撑。【方法】试验设5个不同移栽密度处理,采用宽窄行种植,小区对比试验,以确定黄花菜的最佳种植密度。【结果】合理的种植密度能促进叶片长度和宽度的增长,随移栽密度的增大,叶片长度和宽度呈现减小的趋势;不同移栽密度对黄花菜的抽薹数、花蕾数、单蕾重量以及产量都有明显的影响,合理的密植有利于黄花菜的生长和产量的提高。不同的移栽密度对黄花菜的品质也有一定的影响,合理的密植有利于提高黄花菜营养成分的含量,移栽密度不宜过大或过小。【结论】从不同移栽密度、产量性状以及营养成分变化的整体分析看,黄花菜移栽行距1.4~1.5 m,移栽密度为4450~4760株/667 m2时,其产量和品质均最佳。[Objective]In order to explore the optimal transplanting density of daylily in the arid zone in central Ningxia and improve its yield and quality,the impacts of transplanting density of daylily on its yield and quality were analyzed.The study aims to increase yields and quality of daylilies and provide technical support for land use rate for early planting and economic benefits.[Method]Five different transplanting densities were designed in the experiment.The wide narrow row pattern was adopted.Then the plot contrast experiments were conducted.Finally,the best planting density was determined.[Result]The results showed that the proper planting density could promote the growth of leaf length and width.With the increase of transplanting density,the leaf length and width showed a decreasing trend.Different transplanting density has obvious impacts on daylilies'bolting number,flowers,single bud weight and yields.A proper transplanting density could not only affect the quality of daylilies,but also could enhance daylilies'nutritional components.The transplanting density shouldn't be too big or too small.[Conclusion]The comprehensive analysis of various transplanting density,yield traits and composition changes indicates that the yields and quality of daylilies are the best when the transplanting spacing is between 1.4 m and 1.5 m,and the transplanting density is between 4450~4760 plants/667 m2.
