| 英文摘要 | Climate change will cause an increased frequency and intensity of drought in irrigated arid-zone agricultural areas resulting in a greater need for water conservation. Many water-scarce arid-zone agricultural areas, such as California's San Joaquin Valley (SJV), have shifted from sprinkler and flood irrigation on low cash crops to micro-irrigation on high cash crops, which is a continuing trend throughout the world. As prolonged droughts place increasing demands on water conservation, not only will micro-irrigation systems on high cash crops become more prevalent, but greater focus will be placed on maximizing the water efficiency of micro-irrigation systems. Development of site-specific micro-irrigation management (SSMIM) technology is envisioned as crucial in maintaining the future productivity of water-scarce agricultural areas like the SJV. It is the objective of this paper to present a review of the milestone research and integration of the concepts for managing soil salinity utilizing SSMIM, which can serve as a framework for its future development and implementation. The topics covered include (i) mapping soil spatial variability with apparent soil electrical conductivity directed soil sampling, (ii) data fusion to improve soil spatial variability mapping, (iii) field-scale mapping of soil salinity under micro-irrigation, (iv) determination of leaching requirement (LR) with transient models, (v) an alternative unbiased plant salt tolerance approach to more accurately determine LR, (vi) site-specific management, (vii) degraded water reuse for water-scarce irrigated agricultural areas, (viii) framework for the development of a SSMIM system, (ix) infrastructure and knowledge adjustments necessary to operate SSMIM systems, and (x) existing knowledge gaps to bring SSMIM to fruition. California's San Joaquin Valley, Imperial Valley, and Napa Valley are used to explain the concepts behind SSMIM. Along with genetically modified crops and degraded water reuse, SSMIM is envisioned as a key water conservation technology for global food security by maintaining productivity within agriculturally productive regions susceptible to water scarcity. The presented climate-smart technology is of value and benefit to soil and water researchers, cooperative extension specialists, irrigation specialists, water resource managers, natural resource conservation specialists, agricultural consultants, and producers. |
