【Abstract】Objective: To investigate the effects of chrysanthemum-wheat rotation system and biological manure on continuous cropping soil enzyme activities and quality and yield of Chrysanthemum morifolium. Methods: Field experiments were conducted at the research base of Anhui Jutai Chuju Chrysanthemum morifolium Herbal Technology Co., Ltd., in Shiji Town, Nanqiao Country, Anhui Province. Samples were collected from treatments under chrysanthemum-wheat rotation system receiving bio-organic manure application of 200 kg/667 m2, conventional chrysanthemum-wheat rotation system and chrysanthemum continuous cropping system. Results: Chrysanthemum-wheat rotation system and biological manure obviously influenced the quality and yield of Chrysanthemum morifolium and continuous cropping soil enzyme activities. Compared with chrysanthemum continuous cropping system, total flavonoids, chlorogenic acid, soluble sugar and free amino acid content, quantitative of ray floret, inflorescence diameter, diameter of tubular floret, number of branches, number of flower and yield of Chrysanthemum morifolium and the activities of urease, acid phosphatase, invertase and protease in soil increased to 42.59 mg/g, 2.52 mg/g, 4.04 mg/g, 73.33 mg/100 g, 179.56, 5.57 cm, 1.43 cm, 36.10, 330.00 and 400.09 kg/667 m2, respectively, while hydrogen peroxidase of soil under chrysanthemum-wheat rotation system decreased. Conclusion: Bio-organic manure application of 200 kg/667 m2 is beneficial to soil environment establishment of chrysanthemum-wheat rotation system and enhancement of quality and yield of Chrysanthemum morifolium while reducing the obstacles of continuous cropping.
