| Abstract: |
| 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. |
