Research Progress in Alleviating Continuous Cropping Obstacles by Allium L.Plants
摘要
Abstract
Soil continuous cropping obstacles commonly occur in many plants,such as grain crops,fruit trees,vegetables,Chinese herbal medicines and others,restricting the healthy and sustainable development of the industry.Intercropping,rotation and relay intercropping are important agricultural management measures,and they can regulate the microecological environment of rhizosphere soil of continuous cropping,reducing the harm of continuous cropping.Allium L.plants contain various biologically active components such as organic sulfur compounds,saponins,flavonoids,and other compounds.They are often used as an intercropping,rotation or relay intercropping crop to alleviate continuous cropping obstacles.This paper expounded the alleviative effects of Allium L.plants on continuous cropping obstaces,and the alleviating mechanism of Allium L.plants on continuous cropping obstacles was discussed from photosynthetic characteristics,antioxidant enzyme activity,root exudate characteristics and soil nutrients,enzyme activity and microorganisms quantity and community structure.The components contained in root exudates and plant volatiles of Allium L.plants were analyzed.Finally,the research direction of mechanisms of Allium L.plants alleviating continuous cropping obstacles and the development of active substances were proposed,which laid a theoretical foundation for further application of Allium L.plants in alleviating continuous cropping obstacles.关键词
