These media were mixed with each other and cultured in a 5 *8 hole culture tray. After 10-15 days of cultivation, seed germination in different media was determined. Bud percentage, plant height and stem diameter of seedlings. Under the same conditions, calendula, melon leaf chrysanthemum and Daisy were cultured in different media until the third true leaf grew. The final results were as follows: under the mixed media of garden soil, River sand, perlite (vermiculite) and coconut chaff, the germination rate of calendula, melon leaf chrysanthemum and Daisy was the highest, and the growth condition was the best, regardless of plant height or stem diameter. Compared with other media, there are significant differences. Key words Different culture media: Calendula, Daisy and Chrysanthemum morifolium; Seed germination; Seedling growth 绪论 1.1 研究背景 1.1.1
