In this paper, Chrysanthemum morifolium was used as the experimental object, eight different planting periods were set up in field plot experiment from April to August, which were 04-15, 05-19, 05-30, 06-09, 06-19, 07-20, 07-31, 08-15. The effects of different treatments on the occurrence of root rot, agronnmic traits, mineral element absorption and content of effective components of Ch. morifolium in Macheng country of Hubei province were studied. The results showed that delaying the planting time could effectively reduce the diseases occurrence of root rot of Ch. morifolium. With the advance of transplanting period, the plant height, the weight of one hundred flowers and the number of flowers of Ch. morifolium showed a trend of gradual decrease, while the number of primary branches and the thickness of main stem and the primary branch increased first and then decreased. The yield of Ch. morifolium per plant and per mu increased with the advance of the planting period, and the yield per mu increased during the planting period on June 19, which was 91.96% higher than that on April 15. And with the delay of the planting period,the absorption and accumulation of potassium(K) elements was promotes. The content of active ingredients such as chlorogenic acid, rutin, luteolin, and 3,5-O dicoffeoacy lquinic acid in the Ch. morifolium increased significantly and then gradually decreased with the delay of the planting period, which indicates that late planting can significantly improve the quality of Ch. morifolium. Considering factors such as the occurrence of root rot disease, yield and active ingredient content, combined with climatic conditions in the Dabie Mountains in eastern Hubei, the optimum planting period of Ch. morifolium was determined from mid-late June to early July.
本文以菊花为试验对象，于4月至8月在田间小区试验中设置了8个不同的种植时期，分别为4月15日、5月19日、5月30日、6月9日、6月19日、7月20日、7月31日、8月15日。研究了不同处理对湖北省麻城市菊花根腐病发生情况、农艺性状、矿质元素吸收及有效成分含量的影响。结果表明，推迟种植时间可有效降低菊花根腐病的发病率。随着移栽期的提前，菊花的株高、百花重和花朵数呈逐渐下降趋势，而一级分枝数、主茎和一级分枝的粗度则先增加后下降。单株和每亩菊花的产量随种植期的提前而增加，6月19日种植期的每亩产量比4月15日的高出91.96%。并且随着种植期的推迟，钾（K）元素的吸收和积累得到促进。菊花中绿原酸、芦丁、木犀草素和3,5-O-二咖啡酰奎宁酸等活性成分的含量随着种植期的推迟先显著增加后逐渐下降，这表明晚播可显著提高菊花品质。综合考虑根腐病发生情况、产量和活性成分含量等因素，结合鄂东大别山的气候条件，确定菊花的最佳种植期为6月中下旬至7月上旬。
