摘要
试验研究不同灌水对 10个冬小麦品种农艺性状、产量和水分利用效率的影响结果表明 ,不同冬小麦品种对水分亏缺的响应规律基本相同 ,但品种间有一定差异 ,充分灌水处理冬小麦生物量较大且水分利用效率较低 ,而灌 2水 (拔节～抽穗水 )处理效果较佳 ,其中“6 36 5”抗旱性能和产量潜力最佳 ,水分利用效率也较高。
Agricultural traits of root and canopy, and water use efficiency of 10 wheat varieties were analyzed under different irrigations. The results show that different wheat varieties under the same water deficit are almost alike. But there are some differences among 10 wheat varieties. The sufficient irrigation can increase the biomass of winter wheat but decrease the water use efficiency. Two times of irrigation can get the highest water use efficiency and a very high yield. The experiments also show that '6365' is better for water use efficiency, and is the best for drought resistance capacity and yield potential.
