| 摘要 | Continuous cropping can bring economic benefits in a short time and meet the growing demand of agricultural products such as grain, but long-term continuous cropping will accelerate soil degradation, lead to the reduction of crop yield and the increase of disease rate, and destroy the balance of soil microbial structure. Therefore, it is not conducive to the sustainable development of soil ecosystem. In this paper, the problems caused by continuous cropping, such as imbalance of soil microbial flora, decrease of biodiversity, accumulation of root exudates and their effects on soil fertility and crop growth, were summarized, and some measures were suggested to alleviate the obstacles of continuous cropping, such as reasonable rotation, adjustment of intercropping planting mode and application of biological fertilizers. Moreover, the paper also looked forward to the development trend of continuous cropping obstacle reduction techniques, including the integration and application of biological techniques, the promotion of green ecological techniques and the application of intelligent management system. This study provides theoretical basis and technical support for the research of continuous cropping obstacle reduction techniques and promote the healthy and sustainable development of modern agriculture. |
