Abstract:

The paper aims to solve the problems of less available nutrients and poor quality caused by excessive fertilization in facility cultivation of cut chrysanthemum. We summarized the research progress of cut chrysanthemum’s fertilizer uptake and nutritional regulation, and the effects of macronutrients, micronutrients and technology to improve the fertilizer utilization efficiency on the growth and development of cut chrysanthemum. It is concluded that the nutrient requirements of different cut chrysanthemum varieties share similar patterns in the same growth period or organ, but the optimal fertilizer ratio and application amount need to be adjusted according to different cultivation substrates, soil or environments. Fertilization on demand and supporting techniques play an important role in improving soil structure and quality of cut chrysanthemum. It is considered that scientific research and production should be closely combined to make a profound study on the mechanism and technology of efficient absorption and utilization of nutrients, and speed up the establishment of a standard fertilization system suitable for local requirement, so as to promote the specialized, large-scale and intensive development of cut chrysanthemum production.

Key words: cut chrysanthemum, fertilizer requirement rule, macronutrient, micronutrient, fertilizer utilization efficiency
