摘　　要：[目的]对婺源皇菊栽培过程侧枝疏除量与株高、茎粗、花朵直径以及单株产量、倒伏率之间的影响进行研究。[方法]对大田样株进行人工疏除处理,分别设不疏枝(CK)、疏除20%侧枝(处理Ⅰ)、疏除40%侧枝(处理Ⅱ)、疏除60%侧枝(处理Ⅲ)、疏除80%侧枝处理(处理Ⅳ)4个处理,由同一人同一天内完成。[结果]疏枝处理之后,单株整体株高有增加的趋势,除CK与处理Ⅰ外,其余各处理之间存在显著差异;单株主茎茎粗与CK相比,均存在差异,其中处理Ⅳ倒伏率降到0;平均单株花朵数处理Ⅰ与CK相比差异不显著,其余3个处理的平均单株花朵数明显低于CK,呈现显著差异,但单花鲜花平均直径处理Ⅳ最大,达6.5 cm,与CK存在极显著差异;在单株产量方面,处理Ⅲ鲜重值最高。[结论]侧枝疏除量60%的处理对于保证婺源皇菊的大菊特性和花朵品质、节省生产成本、保证产量等方面具有积极作用。[Objective]The effects of lateral branch thinning on plant height,stem diameter,flower diameter,yield per plant and lodging rate were studied,in order to provide theoretical guidance for practical production.[Method]Field samples were treated by artificial thinning,including four treatments with no thinning(CK),thinning 20%side branches(treatment I),thinning 40%side branches(treatment II),thinning 60%side branches(treatment III),thinning 80%side branches(treatment IV),by the same person on the same day.[Result]After thinning treatment,the whole plant height increased,but there was no significant difference among treatments.The whole stem diameter of single plant was different from CK,in which the IV lodging rate was reduced to 0.The average number of flowers per plant was not significantly different from CK,but treatment IV was the largest,reaching 6.5 cm,and the fresh weight of Treatment III was the highest in yield per plant.[Conclusion]The treatment of 60%thinning of side branches had a positive effect on the quality of Wuyuan Chrysanthemum,the production cost and the yield.
