Abstract The ridge-furrow rainfall harvesting system (RFRHS) is an in-situ rainfall collection and utilization technique that has been widely adopted in global arid and semiarid farming areas because of its significant benefits to soil water availability and crop yield. However, the integrated effects of different ridge-furrow configurations on rainwater collection and crop performance are still lacking. Using a specialized database drawn from field experiments in the Loess Plateau, we examined the regional effects of three typical ridge-furrow configurations, namely high (>1:1), uniform (=1:1), and low (

垄沟配置显着提高了黄土高原旱地农业生态系统的土壤水分可用性、作物水分利用效率和粮食产量

摘要 垄沟雨水收集系统（RFRHS）是一种就地雨水收集利用技术，因其对土壤水分利用率和作物产量具有显着效益而被广泛应用于全球干旱和半干旱农区。然而，不同垄沟配置对雨水收集和作物性能的综合影响仍然缺乏。使用从黄土高原现场实验中提取的专业数据库，我们检查了三种典型的垄沟配置的区域效应，即高 (>1:1)、均匀 (=1:1) 和低 (
