Abstract:

Driven by intensive planting and economic benefits, continuous cropping, planting a single crop in the field year after year, has become a common planting mode in China. Long-term continuous cropping has caused many problems, including serious pests and diseases, low yields, and deteriorating soil health. Crop rotation is one of the effective solutions to continuous cropping obstacles and plays a crucial role in the implementation of national strategies such as food security, ecological environment development, and rural revitalization. The paper expounded on the economic and ecological benefits of crop rotation compared with continuous cropping through literature review, and provided suggestions for developing China’s crop rotation based on the comparison of domestic and foreign crop rotation systems. The results show that compared with continuous cropping, crop rotation has higher economic and ecological benefits. Also, it is found that China’s current crop rotation system differs from foreign countries in terms of guidance, promotion mechanisms, subsidy methods, and regulatory measures, and there are still many problems in the development process of crop rotation in China. Combining with the experiences of foreign crop rotation, this paper proposes that we should formulate scientific crop rotation plans, develop crop rotation techniques (conservation tillage, cover crops, water-saving irrigation, and etc.), strengthen the promotion of crop rotation, accurately implement the crop rotation policy, and timely carry out reasonable evaluation and policy adjustments, which have a guiding significance for the large-scale development of crop rotation in China.

Key words: crop rotation, economic benefit, ecological benefit, soil health, policy suggestion
