我国燕麦水分利用效率和耗水系数

Water Use Efficiency and Water Consumption Coefficient of Oats in China

本文系统总结了我国燕麦(Avena spp.)水分利用效率和耗水系数。我国燕麦饲草、籽实和生物水分利用效率范围依次为5.7~58.4、1.0~21.3和3.4~95.8kg/(mm·hm^(2))。我国燕麦饲草、籽实和生物耗水系数范围依次为171~1754、470~10000和104~2941。我国燕麦饲草、籽实和生物水分利用效率及耗水系数最大值与最小值之比依次为10.3、21.3和28.2,饲草燕麦生产水分利用效率和耗水系数远较籽实燕麦生产稳定。

Water use efficiency(WUE)and water consumption coefficient(WCC)of oats(Avena spp.)in China were systematically summarized in this paper.The extent of WUE of oats for forage,grain,and biological in China were 5.7~58.4,1.0~21.3 and 3.4~95.8 kg/(mm•hm^(2)),respectively.The extent of WCC of oats for forage,grain,and biological in China were 171~1754,470~10000 and 104~2941,respectively.The ratio of maximum and minimum of WUE and WCC of oats for forage,grain,and biological in China were 10.3,21.3 and 28.2,respectively.The WUE and WCC of forage oats production were far stable,comparing to grain oats production.
