轮作模式对杭白菊生长、品质和根际土壤环境的影响
Effects of rotation patterns on growth,quality and rhizosphere soil environment of Chrysan-themum morifolium Ramat.cv.Hangbaiju
摘要
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 flow-ers were significantly higher than those in other treatments,with all yield indicators superior to those in other treat-ments.Although the wheat-chrysanthemum rotation improved individual flower quality,it suppressed early-stage growth,resulting in a survival rate of only80.63%.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 mat-ter.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 Burk-holderia 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.关键词
