玉门气候变化对啤酒花的影响

Influence of Climatic Change on Hops in Yumen

[目的]研究玉门气候变化对啤酒花的影响。[方法]根据玉门镇气象站1953-2010年的气象资料,采用线性趋势和对比分析法,分析了玉门近58年的气候变化及其对啤酒花的影响。[结果]玉门气温、降水量均呈上升趋势,年平均气温上升速率为0.2℃/10a,年降水量增加速率为3.0 mm/10a。年日照时数呈减少趋势,减少速率为25.7 h/10a;年平均风速呈减小趋势,减小速率为0.3m/（s.10a）;无霜期有缩短趋势,积温呈增加趋势。玉门气候变化对玉门啤酒花的产量和质量均产生了一定影响,1989-2008年玉门饮马农场啤酒花单产量和甲酸含量的下降速率分别为543.8 kg/（hm2.10a）、0.5%/10a。[结论]该研究为啤酒花种植提供理论依据。

[Objective] The research aimed to study the influence of climatic change on hops in Yumen.[Method] Has analyzed the Yumenzhen near 58 years Yumen climatic change According to the Yumenzhen weather station meteorological data during 1953-2010,using the linear tendency and the contrast analytic method,the climate change and its influence on the hop in Yumen in near 58 years.[Result] The result indicated that,the Yumen temperature,the precipitation assume the trend of escalation,the annual mean temperature rise speed for 0.2 ℃/10a,the year precipitation the changing is 3.0 mm/10a;annual sunshine hours have slowed,the reduce rate is 25.7 h/10a;verage annual wind speed is reduced,the reduce trend is 0.3 m/（s·10a）;frost-free period has the reduction tendency,the accumulated temperature assumes the increase tendency.the Yumen climatic change has all had certain influence on the output and quality of hops,the per unit area yield quantity and the formic acid content of hops drop speed respectively is 543.8 kg/（hm2·10a）,0.5%/10a during 1989-2008 in Yumen waters horse farm.[Conclusion] The study provides the theoretical basis for the hop growing.
