We studied the effects of different irrigation methods on the yield, quality, stress resistance and water use efficiency of Chrysanthemum morifolium. The results showed that water-saving irrigation and precision irrigation during the growth period could significantly improve the water use efficiency without affecting the yield. If sufficient irrigation is adopted, although the yield per mu is the highest, the water use efficiency is poor. We also noticed that the amount of effective components such as flavonoids and volatile oil would change with different irrigation methods. Among them, precision irrigation can make these medicinal ingredients accumulate more. Water saving irrigation also makes chrysanthemum more drought resistant and disease resistant, and powdery mildew and leaf spot disease occur less. The study also shows that efficient irrigation methods such as drip irrigation can further improve water use efficiency and provide a good help for planting in different regions. This study provides a theoretical basis and technical methods for the efficient planting of Chrysanthemum morifolium. By adjusting the irrigation strategy, it can not only save water resources, but also promote the development of chrysanthemum industry, and also help to promote the development direction of green agriculture.
