摘要 在干旱半干旱区,降水有限且时空分布不均,作物产量低而不稳定,严重制约着当地农业生产的发展,如何高效利用该地区的水肥光热等资源,实现农业上的高产稳产及可持续发展是当前该农业区面临的重要问题。垄沟集雨种植技术作为一种高效节水栽培措施,可有效缓解当地降水资源利用率低的问题,显著改善作物生长发育过程中所需的水热环境,因而在当地得到了广泛推广与应用。综合国内外垄沟集雨种植模式的研究进展,从土壤水热环境、作物光合特性、作物养分吸收和作物生长发育四个方面进行归纳总结,分析垄沟集雨种植模式下改变垄沟结构对作物生长发育的影响,并对未来干旱半干旱区集雨农业发展作出展望。 In the arid and semi-arid area,limited precipitation and uneven spatial and temporal distribution,low and unstable crop yields,seriously restricts the development of local agricultural production.How to efficiently utilize water,fertilizer,light and heat and other resources in the region,to achieve high and stable yields and sustainable development of agriculture is an important issue facing the current agricultural region.As an effective water-saving cultivation practice,the ridge-furrow rainfall harvesting technology can effectively alleviate the problem of low utilization of local precipitation resources and significantly improve the water and heat environment required in the process of crop growth and development,and thus it has been widely promoted and applied in the region.In this paper,we synthesize the research progress of rainfed cropping pattern at home and abroad,summarize the four aspects of soil hydrothermal environment,crop photosynthetic characteristics,crop nutrient absorption and crop growth and development,to analyze the effects of changing the structure of ridges on the growth and development of crops under the ridge-furrow rainfall harvesting pattern,and to make outlooks on the future development of rainfed agriculture in arid and semi-arid zones.
