摘　　要：目的:研究镁螯合肥对万寿菊花生长及产量品质的影响,筛选最适施用量。方法:采用单因素随机区组设计,以清水为对照,设置5个浓度处理进行叶面喷施。结果:喷施1200倍液镁螯合肥对花直径影响显著;喷施1000倍液花鲜产量最高,为21973.3 kg/hm^(2),较CK高49.5%,第一茬和第二茬花中黄酮、多酚和叶黄素含量分别为50.09、54.54、6.86 mg/g和58.48、60.09、7.82 mg/g,灰分、酸不溶性灰分、水溶性浸出物和醇溶性浸出物分别为5.97%、0.48%、29.19%、25.82%和5.74%、0.44%、28.33%、26.94%。结论:喷施镁螯合肥可促进万寿菊的生长,提高其产量和品质,1000倍液镁螯合肥效果最佳。Objective:To study the effects of magnesium chelate on the growth,yield and quality of Tagetes erecta.And the optimum application amount was selected.Methods:A single factor random block design was used with clean water as the control.And five concentration treatments were set up for foliar spraying.Results:Spraying 1200 times liquid magnesium chelate had significant effect on flower diameter.The highest yield of liquid flower was 21973.3 kg/hm^(2) after spraying 1000 times,which was 49.5%higher than CK.The contents of flavonoids,polyphenols and lutein in the first and second crops were 50.09 mg/g,54.54 mg/g,6.86 mg/g and 58.48 mg/g,60.09 mg/g,7.82 mg/g,respectively.Ash,acid-insoluble ash,water-soluble extract and alcohol-soluble extract were 5.97%,0.48%,29.19%,25.82%and 5.74%,0.44%,28.33%,26.94%,respectively.Conclusion:Spraying magnesium chelate can promote the growth of T.erecta,improve its yield and quality.And 1000 times liquid magnesium chelate was the best.
