Abstract Strip intercropping has been widely applied in arid and semi-arid regions due to high and stable productivity and efficient utilization of resources. Intercropping can increase water use efficiency (WUE) of crops and optimize the soil moisture environment for crop development. Competition and complementarity are two aspects of the same interspecific relationship between crops, and a quantitative understanding of the competition and complementary effects of intercrops on soil resources is important for advancement of intercropping systems. The characteristics and mechanisms of water utilization and interspecies relationships in intercropping are reviewed in this paper. The main regulation approaches for efficient water utilization in intercropping are based on interspecific competition and complementarity include crop species, irrigation and fertilization regimes, plant density, spatial arrangement, tillage and mulching practices, and environmental factors. Interspecific competition and complementarity are leading factors influencing water utilization of intercrops and studies on synergistic effects of competition and complementarity in intercropping systems are of importance for water utilization. Future research should investigate the relationship between water competition and complementation between different intercrops and inter-zone water migration. Integrating results from different studies could provide a basis for enhancing WUE of intercropping through advanced understanding of approaches for regulating interspecific interactions. This would provide support for the development and adoption of intercropping systems in water-deficient areas.

间作用水：综述

摘要 条带间作由于产量高且稳定，资源利用效率高，在干旱半干旱地区得到广泛应用。间作可以提高作物的水分利用效率（WUE），优​​化作物生长的土壤水分环境。竞争和互补是作物之间相同种间关系的两个方面，定量了解间作对土壤资源的竞争和互补效应对于推进间作系统很重要。本文综述了间作水分利用的特点和机制以及种间关系。间作有效水资源利用的主要调控方法是基于种间竞争和互补性，包括作物品种、灌溉和施肥制度、植物密度、空间布置、耕作和覆盖做法以及环境因素。种间竞争和互补是影响间作水分利用的主要因素，研究间作系统中竞争和互补的协同效应对水资源利用具有重要意义。未来的研究应探讨不同间作和区域间水分迁移之间的水分竞争与互补之间的关系。通过深入了解调节种间相互作用的方法，整合不同研究的结果可以为提高间作的 WUE 提供基础。这将为缺水地区间作系统的开发和采用提供支持。
