| Abstract: | The obstacles for continuous cropping of crops had been an important factors which affecting sustainable development of agriculture and forestry in China.The concept of pathogenic obstacles for continuous cropping was briefly introduced at first.Then,the changes in structure of rhizosphere microorganism population,the carbohydrate in root exudates and the function of carbohydrate in root exudates that inducing proliferation of pathogen population under the conditions of continuous cropping were summarized.And then,the effect of some allelochemicals in root exudates in proliferation of pathogen population and the chemical communication molecular among soil microorganisms were also summarized.In the end,the direction and emphases of the research in the future were prospected. |
| Keywords: | Root exudates soilborne disease obstacles for continuous cropping review |
