ABSTRACT
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.
