| 中文摘要: |
| 在防雨池栽培试验条件下,研究了有限灌溉对两个燕麦品种产量品质和水分利用效率的影响。试验为裂区设计,主区为7个灌溉处理,副区为品种(内农大莜1号,白燕7号)。研究结果表明:水分过分亏缺或后期灌水过量均显著影响到燕麦干物质积累;内农大莜1号的干草产量、籽粒产量以及粗蛋白产量均为E处理(底墒水+拔节水+抽穗水)最高,而白燕7号的以上三种产量是以F处理最高;两个品种均是E处理具有最高的水分利用效率(WUE),过度干旱(处理A)或后期灌水过多(处理G)均显著影响燕麦土壤水分利用效率;内农大莜1号具有更强的抗旱性,而白燕7号则对水分更为敏感。 |

| This paper studied the effect of limited irrigation on yield,quality and water use efficiency of two oats under rainfall-proof-through in the center of horticulture research in Inner Mongolia Hohhot.Irrigation treatments were allocated as main plots within a split-plot design.Two oats varieties(Neinongdayou No.1 and Baiyan No.7) were allocated to sub-plots.The result showed that the dry matter accumulation amount decreased with severe deficiency(treatment A) or over-content(treatment G) of soil moisture although there was difference among different treatments.The highest yield of grass,seed and crude protein of Neinongdayou No.1 was by treatment E,which irrigated in jointing stage and heading stage before sowing,but that of Baiyan No.7 was by treatment F.Treatment E had the highest WUE in two cultivars,severe deficiency(treatment A) or over-content(treatment G) of soil moisture remarkably influenced effective use of soil water.Neinongdayou No.1 had a strong drought resistance,and Baiyan No.7 was sensitive to soil moisture. |
