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. Keywords Chrysanthemum morifolium; Irrigation strategies; Yield; Quality; Water use efficiency 1 Introduction Chrysanthemum morifoliumis a common ornamental plant. It is not only beautiful, but also has high economic and medicinal value. It can be used in traditional Chinese medicine and daily herbs, and is very popular in the flower market because of its beautiful flower shape (Sun et al., 2010; Yuan et al., 2020; Hao et al., 2022; Cai et al., 2024). Irrigation is particularly important when growing chrysanthemum. In order to improve yield and quality, irrigation methods should be selected well. Many studies have discussed this issue, indicating that reasonable water use can help it grow better and blossom better (Amarin et al., 2021; Gurjar et al., 2023). Now water resources are becoming increasingly scarce, so we need to study more water-saving irrigation methods to ensure that Chrysanthemum morifolium can be continuously planted (Amarin et al., 2021). Irrigation methods will directly affect the growth and flower quality of Chrysanthemum morifolium. For example, drip irrigation and irrigation with treated wastewater, different methods will affect the number, size and overall quality of flowers. The results showed that more and better quality flowers could be planted by controlling the amount of drip irrigation; Wastewater irrigation can sometimes improve soil conditions and is also good for plants (Gurjar et al., 2023). In addition, the experiment of irrigation with saline water showed that Chrysanthemum morifoliumcould tolerate a certain amount of salt, but the change of salinity would affect its physiological state and appearance (Amarin et al., 2021). Our study will test several different irrigation methods to see how they affect the yield and quality of Chrysanthemum morifolium. We want to find out which irrigation method can save water without degrading the quality of flowers, or even become better. At the same time, we will also see how the growth and reaction of Chrysanthemum morifolium will change when irrigated with saline water or wastewater. It is hoped that these results can provide some practical suggestions for growers, help them grow high-quality Chrysanthemum under the condition of water shortage, and realize a more water-saving and environmental friendly planting method.
