耕作模式对作物水分利用效率影响的研究进展

Research Progress on the Impact of Tillage Patterns on Crop Water Use Efficiency

摘要: 我国水资源整体上短缺，农业生产又对水资源高度依赖，提高作物水分利用效率，已成为农业科学领域的重要研究课题。本文通过对耕作模式对土壤水分状况、作物生长和产量、水分利用效率研究进展的讨论分析，研究得出耕作模式对土壤水分状况的影响主要体现在土壤水分的保持、渗透和分布方面；对作物生长和产量的影响主要体现在改变土壤环境、养分供应方式等方面；对水分利用效率的影响主要体现在改善土壤通气性和渗透性、影响土壤水分状况等方面。未来的研究还应更加关注耕作模式与其他农业生产因素的相互作用，通过综合考虑这些因素，可以更全面地评估耕作模式对作物水分利用效率的影响，为农业生产提供理论依据和技术支持。

Abstract: China is generally short of water resources, and agricultural production is highly dependent on water resources. Improving crop water use efficiency has become an important research topic in the field of agricultural science. This article discusses and analyzes the research progress of tillage pat-terns on soil moisture status, crop growth and yield, and water use efficiency. It is found that the impact of tillage patterns on soil moisture status is mainly reflected in the maintenance, infiltration, and distribution of soil moisture; the impact on crop growth and yield is mainly reflected in chang-ing soil environment, nutrient supply methods, and other aspects; the impact on water use efficiency is mainly reflected in improving soil aeration and permeability, and affecting soil moisture status. Future research should also pay more attention to the interaction between tillage patterns and other agricultural production factors. By comprehensively considering these factors, the impact of tillage patterns on crop water use efficiency can be more comprehensively evaluated, providing theoretical basis and technical support for agricultural production.
