| Abstract: | The influences of continuous cropping on the morphology,physiology,quality and yield of plants were summarized;and the formation mechanism of continuous cropping obstacle was analyzed from six different aspects,including changes of pests,nutrition content,physicochemical properties,autotoxin substances,enzymatic activities and microbial communities of the soil.The complexity of interaction among plants,soil microbes,soil enzymes and soil nutrients was pointed out to provide prospects for future study on the mechanism of continuous cropping obstacle. |
