Abstract:

Long-term continuous cropping of Chrysanthemum morifolium Ramat. cv. Hangbaiju has resulted in soil nutrient imbalance, microbial community disruption, and intensified pest and disease pressure, thereby constraining sustainable industrial development. This study established three rotation patterns: barley (Hordeum vulgare L.)-chrysanthemum, wheat (Triticum aestivum L.)-chrysanthemum, and bok choy [Brassica rapa var. chinensis(L.) Kitam.]-chrysanthemum, using continuous chrysanthemum cropping as the control, to systematically evaluate their effects on the growth, quality and rhizosphere soil environment of Chrysanthemum morifolium. The results showed that in the barley-chrysanthemum rotation, the flower number per plant, number of petals and dry weight of 10 flowers were significantly higher than those in other treatments, with all yield indicators superior to those in other treatments. Although the wheat-chrysanthemum rotation improved individual flower quality, it suppressed early-stage growth, resulting in a survival rate of only 80.63%. The effect of the bok choy-chrysanthemum rotation was similar to that of the control. No significant differences were observed in chlorogenic acid, luteolin-7-O-glucoside and 3,5-O-dicaffeoylquinic acid contents among treatments, all of which met the standards of Chinese Pharmacopoeia. Rotation with gramineous crops significantly increased the contents of soil total nitrogen, ammonium nitrogen and organic matter. Microbial diversity analysis revealed that barley-chrysanthemum and wheat-chrysanthemum rotations exhibited significantly higher Shannon indices compared with the control, with enrichment of beneficial genera including Burkholderia and Phyllobacterium, thereby optimizing rhizosphere microbial community structure. Comprehensive analysis indicated that the barley-chrysanthemum rotation significantly promoted the growth, development and yield formation of Chrysanthemum morifolium by improving soil fertility and optimizing the rhizosphere microbial community. It was a superior rotation pattern for alleviating the continuous cropping obstacles of Chrysanthemum morifolium, providing a theoretical basis and technical support for its sustainable production.
