作物轮作的优势与劣势及研究展望

摘 要：由于盲目追求经济效益，在同一块土地上长期种植同种作物，致使土壤发生连作障碍。目前有多种方法缓解连作障碍，而轮作因其具有低消耗、低投入、可持续发展等优点而被广泛应用。该文分析了轮作的优势和劣势，并对今后的研究进行了展望，以期为优化作物轮作模式提供参考。

Abstract： People blindly pursue economic benefits and plant the same crops for a long time， which resulted in the continuous cropping obstacles in the soil. At present， there are several methods to alleviate continuous cropping obstacles. However， crop rotation has been widely used to alleviate continuous cropping obstacles due to its advantages of low consumption， low input and sustainable development. Crop rotation model is analyzed. The advantages， disadvantages and research prospects of crop rotation are described， in order to provide reference for the optimization of crop rotation model.
