摘要
青稞(Hordeum vulgare L. var. nudum)作为青藏高原特色作物,其蒸散过程对水分利用效率与产量形成至关重要。综述了青稞蒸散组分的研究进展,涵盖了蒸散的概念、研究方法,重点阐述了青稞蒸散各组分(土壤蒸发和作物蒸腾)的影响因素及定量研究成果,讨论了当前研究存在的问题与未来发展方向,旨在为深入了解青稞水分利用规律,优化青稞种植灌溉管理及高原节水农业提供理论支持。
As a characteristic crop of the Qinghai-Xizang Plateau,the evapotranspiration process of Highland barley(Hordeum vulgare L.var.nudum)is crucial for water use efficiency and yield formation.This article reviews the research progress on the evapotranspiration compo-nents of Highland barley,covering the concept and research methods of evapotranspiration.It focuses on the influencing factors and quantita-tive research results of each component of barley evapotranspiration(soil evaporation and crop transpiration).At the same time,it discusses the current research problems and future development directions,aiming to provide theoretical support for a deeper understanding of barley water use patterns,optimization the irrigation managerment of Highland barley planting,and water-saving agriculture in the plateau.
