摘要 以陇亚杂1号为材料,研究了不同灌水处理对胡麻籽粒产量和水分利用效率的影响。结果表明,胡麻的总耗水量随着灌水量的增加而增加。与不灌水处理相比,现蕾期灌水180 mm处理和盛花期灌水180 mm处理的产量水分利用效率分别显著增加了17.14%和9.26%。胡麻籽粒折合产量随灌水量的增加,呈现先增加后降低的趋势,其中现蕾期灌水180 mm处理的折合产量最高,达2 461.32 kg/hm^2,较不灌水处理显著增产952.29kg/hm^2,增产率63.11%;盛花期灌水180 mm处理的折合产量为2 354.55 kg/hm^2,较不灌水处理增产56.03%。综上所述,现蕾期灌水180 mm是胡麻兼顾高产和节水的最佳灌溉方式。 Longyaza 1 as materials,the effects of different irrigation on yield and water use efficiency of oil flax seed is studied. The result shows that the total water consumption of flax increased with the increase of irrigation amount,compared with no irrigation,yield and water utilization efficiency are significantly increased 17.14% and 9.26%,higher than that of the check no irrigation,which irrigation amount 180 mm at the budding stage and irrigation amount 180 mm at the full flowering stage. The equivalent yield of flax grain with the increase of irrigation water,showing the trend of first increased and then decreased,which the equivalent yield of irrigation amount 180 mm at the budding stage is the highest,reached 2 461.32 kg/hm^2 and 63.11% higher than that of the check no irrigation,significantly increased yield 952.29 kg/hm^2;the equivalent yield of irrigation amount 180 mm at the flowering stage is 2 354.55 kg/hm^2 and 56.03% higher than that of the check no irrigation. In summary,irrigation amount 180 mm at the budding stage is best irrigation method and both high yield and water saving.
