摘　　要：本文系统总结了我国燕麦(Avena spp.)耗水强度及其影响因子研究结果。燕麦耗水强度的影响因子包括降水量、降雨季节分配、地形、播种期、灌溉、施肥、混播、耕作方式和茬口;在一定范围内,雨养燕麦耗水强度与降水量直线正相关,灌溉燕麦耗水强度与灌溉量直线正相关;我国燕麦耗水强度范围为0.6~5.8 mm/d。我国各地燕麦耗水强度动态曲线差别明显。Water consumption rate and its influence factors of oats(Avena spp.)in China were systematically summarized in this paper.The influence factors of water consumption rate of oats included precipitation,season distribution of rainfall,terrain,seeding time,irrigation,fertilization,mixed planting,farming methods and fore crop.Within a certain range,water consumption rate of rain-fed oats were linear positive correlation with precipitation,water consumption rate of irrigation oats were linear positive correlation with irrigation amount.The extent of water consumption rate of oats in China were from 0.6 to 5.8 mm,respectively.The dynamic curve of water consumption rate of oats in China were different.
