目的:探讨轮作模式与生物有机肥施用对滁菊产量、品质及连作土壤酶活性的影响。方法:以连作9年的滁菊试验田为研究对象,设置滁菊连作模式、常规滁菊小麦轮作模式和滁菊小麦轮作模式配施生物有机肥三个处理,分别测定土壤酶活性、滁菊产量与品质指标。结果:采取菊麦轮作可显著提高滁菊中总黄酮、绿原酸、可溶性糖及游离氨基酸含量,且在配施生物有机肥下表现最优,其含量分别达到42.59 mg/g、2.52 mg/g、4.04 mg/g、73.33mg/100 g。菊麦轮作有利于促进滁菊生长,改善滁菊花序性状,滁菊有效分支增加,花头数显著提高,进而提高单株鲜花数量。在试验条件下,菊麦轮作模式表现出较高的增产效果,与滁菊连作模式相比产量增加最高可达28.21%,产量达400.9 kg/667 m2。菊麦轮作模式可显著提高滁菊连作土壤脲酶、酸性磷酸酶、蔗糖酶和蛋白酶活性,降低土壤过氧化氢酶活性。结论:通过采用合理的菊麦轮作和增施生物有机肥,可以有效促进滁菊生长和产量形成,提高滁菊品质,改善土壤肥力状况,有效减轻滁菊连作障碍。
Objective: To investigate the effects of rotation patterns and bio-organic fertilizer application on the yield and quality of chrysanthemum and soil enzyme activities in continuous cropping. Methods: The experiment was conducted in the field of Ju chrysanthemum continuous cropping for nine years. Three treatments including Chu chuang continuous cropping pattern, conventional Chuju wheat rotation pattern and Chuju wheat rotation pattern with biological organic fertilizer were applied to determine the soil enzyme activities, And quality indicators. Results: The yield of total flavonoids, chlorogenic acid, soluble sugar and free amino acids in chrysanthemum increased significantly with the combination of organic-fertilizer and organic fertilizer, and the contents of total flavonoids, chlorogenic acid, soluble sugar and free amino acids were 48.59 mg / g and 2.52 mg / g, 4.04 mg / g, 73.33 mg / 100 g. Jumai rotation is conducive to promoting the growth of chrysanthemum, to improve the chrysanthemum inflorescence traits, chrysanthemum effective branches increased, the number of flower heads significantly increased, thereby increasing the number of flowers per plant. Under the experimental conditions, the yield increase of jujube crop was higher than that of chrysanthemum continuous cropping. The yield increased up to 28.21% and the yield reached 400.9 kg / 667 m2. Juju wheat rotation mode can significantly increase soil urease, acid phosphatase, invertase and protease activities and soil catalase activity. Conclusion: By using reasonable jujube rotation and bio-organic fertilizer application, the growth and yield formation of Chrysanthemum morifolium can be effectively promoted, the quality of Chrysanthemum morifolium increased, the soil fertility improved, and the chrysanthemum continuous cropping obstacle effectively reduced.
