- 摘要:
- 该文利用盆栽试验结果，通过分析胡麻在不同生育阶段对不同强度干旱的产量反应，得出：胡麻各生育期的受旱缺水指数ri，减产指数Ri，及产量反应系数kyi；认为：胡麻不同生育期对干旱的敏感次序为：开花期>现营期>纵形期>苗期>成熟期，且籽粒产量较生物产量敏感；胡麻生育期耗水强度由弱→强→弱，以现雷期日耗水量最大，苗期日耗水很小；在受旱情况下，水分生产率以现蕾期最小，苗期最大，并以现蕾期受旱的减产率最大，达26.7%，其次为开花期、纵形期、成熟期.应用ri、Ri、kyi估算了胡麻气候生产潜力，并进行检验，结果良好，同时还对生物产量反应进行了分析.
- Abstract:
- Based on pot experiment, flax yield response to different degree droughts during its growing periods were analysed.The water deficits index(ri) and the drop productivity index(Ri) and the productivity response index(kyi) were obtained.The results showed that: The response of flax yield was classed by sensitivity to drought in the order: anthesis stage > grain filling stage>tilling stage>seedling stage>ripe stage, and grain yield is more sensitive than that of biomass.2.The degree of evaptranspiration (ET) was from weak to strong then ended with weak, and in filling stage that reached the highest, in seedling stage that was the lowest.3.In the drought condition, the WUE in filling stage was a litter low, and that in seedling reached its highest.The daily drop productivity was the highest in filling stage, reached at 26.7%, the next was in the order: anthesis stage, filling stage, ripe stage, and then seedling stage.The ri,Ri,kyi were used to foretell the flax yield.The estimated results were very close to the real yield, also the biomass response to drought was analysed in the paper.
