    摘要:

    多样化种植是现代生态农业的重要举措之一,对提高生物多样性、生态服务功能和土壤质量等具有重要意义。在全球粮食供给紧张和耕地短缺背景下,多样化种植在提升我国耕地质量和保障粮食安全中将会发挥越来越重要的作用。但现有研究对多样化种植的理解多集中在提高生物多样性和发挥生态功能等方面,对其提升耕地质量的作用关注较少,特别是多样化种植如何通过改善土壤物理、化学、生物多样性来提高耕地质量和维持土壤健康方面的理解还较为局限。本文在总结多样化种植的内涵及对促进耕地土壤健康和提高生态服务功能作用的基础上,系统梳理了多样化种植对改善土壤物理、化学、生物多样性等方面的作用研究进展,展望了未来以提升耕地质量为核心发展多样化种植亟需关注的方向和研究重点,以期为多样化种植在我国耕地质量提升策略中发挥更大作用提供参考。

    Abstract:

    Diversified cropping system is an important strategy of ecological intensive agriculture. It makes significant improvements to soil quality, ecosystem stability and land productivity. Under the background of a global shortage of food supply and cultivated land, diversified cropping system play an increasingly important role in ensuring food security and improving the quality of cultivated land in China. Currently, diversified cropping system has become a research hotspot in soil, ecology, crop, and tillage sciences. Nevertheless, the research about diversified cropping system in the recent period is more focused on improving its biodiversity and ecological functions but with limited understanding of how these diversified systems impact soil quality and productivity due to the changes of soil physical, chemical, and biological properties. In this paper, we analyzed the connotation of diversified cropping system and its significance on promoting soil health and improving ecological service function, and systematically summarized the advances in the effect of diversified cropping system on some soil properties including: (1) Physical properties: We focused on the improvements of soil porosity, aggregates, water binding capacity, etc., by different crop root morphology (biological tillage) and straw inputs under diversified cropping system. (2) Chemical properties: We analyzed diversified cropping system optimized light, water, and heat resources to increase the utilization efficiencies of nitrogen and phosphorus, promote soil organic carbon sequestration, balance soil nutrients and regulate root exudates, mitigate using differences in spatial and temporal niche and nutrient niche between aboveground and underground parts. (3) Biological properties: We reviewed the biological effect and advantageous changes of soil biodiversity under diversified cropping system including soil microbial diversity, arbuscular mycorrhizal fungi, soil enzyme activity, and soil animals. However, there are still some challenges limiting the development of diversified cropping systems including the lack of theoretical systems, production technology and machinery equipment, technological polarization, and policy support. Furthermore, we proposed four areas where future research should focus on improving cultivated land quality by diversified cropping system: (a) Develop multi-functional diversified cropping system including soil amendment, bioremediation, and low-carbon cropping system; (b) Supplement the theoretical system of cultivated land quality improvement under diversified cropping system including crop-soil interaction mechanism and nutrient regulation, ecological versatility and environmental response mechanisms at different scales; (c) Establish appropriate technology system for diversified cropping system including suitable special varieties or their combinations, optimization production technology and machinery equipment; and (d) Applicability and popularization strategies of diversified cropping system including planning and design, policy guidance and financial support to establish typical diversified cropping system in different regions. On the whole, this review provides a reference for the diversified cropping system to play a greater role in the strategy of improving cultivated land quality.
