摘　　要：为了给短葶山麦冬规范化栽培提供理论依据,采用大田随机区组试验,定期采集短葶山麦冬样品,测定各器官生长量,采收时测定产量与多糖、水浸出物等含量,研究不同移栽期对短葶山麦冬生长发育动态、产量及品质的影响。结果表明,不同移栽期的短葶山麦冬地上部生长发育规律相似,均呈"先升后降再缓升"的发育趋势,分蘖数则呈"先快后慢"的趋势。4月份移栽的地上部和地下部生长发育均优于其他移栽期,此间移栽,植株生长迅速,有利于分蘖和块根形成,且增加了块根的发育时间。不同移栽期的产量差异显著,随着移栽期的推迟,产量逐渐下降,多糖和水浸出物含量也随之下降,综合以上研究结果可知适宜的移栽时期为4月初至5月初。To provide a theoretical basis for normalization cultivating measures for Liriope muscari（Decne） Baily,the experimental plots were randomly divided.The biomass of leaf and root were regularly collected and measured.The yield,polysaccharide content and water lixivium were also determined after harvesting.The effects of transplanting time on the growth and development of Liriope muscari（Decne） Baily,root yield and quality were studied.The growing and developing rule of aerial part of L.muscari（Decne） Baily was similar among different transplanting time.Its tendency was described as ＂ ascending,then descending,then slowly ascending ＂.While,the tillering tendency was described as ＂ fast,then slow ＂.The aerial and underground parts of L.muscari（Decne） Baily,which was transplanted in April,grew and developed better.The fast-growing of L.muscari（Decne） Baily transplanted in April was beneficial to tiller,moreover,to increase the root developing time.The root yield was significantly different at different transplanting time.The yield,polysaccharide content and water lixivium decreased with the retarding of transplanting time.In conclusion,the optimum transplanting time of L.muscari（Decne） Baily was from early April until early May.
