利用冕宁县2002－2011年大麦播种、出苗、三叶、分蘖、拔节、孕穗、抽穗、开花、乳熟、成熟10个发育期的实际观测资料，统计出各发育期间的间隔日数、平均气温、降水量、日照时数、活动积温、气温日较差以及每年的实际产量．采用直线滑动平均方法分离出气象产量，并将其与各发育期间的气象因子分别进行点聚图和相关性统计分析，得到不同时段影响冕宁县大麦产量波动的重要气象因子：拔节到孕穗期的间隔日数、平均气温和气温日较差，孕穗到抽穗期的气温日较差，开花到乳熟期的平均气温，三叶到分蘖期的日照时数和孕穗到抽穗期＞0℃积温；再用积分回归求偏回归系数，分析不同发育期气象因子对气象产量的影响程度，得到影响产量的主要气象因素是播种到出苗期的平均气温 a（t）值为236.16 kg／hm2?℃，孕穗到抽穗期的气温日较差 a（t）值为64.73 kg／hm2?℃，其次是播种到出苗期的＞0℃积温 a（t）值为34.79 kg／hm2?℃．

The actual observation data of 10 puberties of barley (sowing ,emergence ,trilobites ,tillering , jointing and booting ,heading ,flowering ,mature milk ,and ripe ,) is made to get the statistics of the inter‐val numbers ,the average temperature ,precipitation ,sunshine time ,active accumulated temperature ,air temperature daily range and the actual output of each year during the development in Mianning County from 2002 to 2011 .The straight‐line moving average method has been used to isolate the meteorological yield .With the meteorological factors during the development point figure and correlation statistical analy ‐sis respectively ,different times important meteorological factors influencing Mianning barley yield fluctua‐tion was got ,which includes the following :interval days of the Jointing stage to booting stage ,the aver‐age temperature and the temperature diurnal range ;temperature diurnal range of booting to heading stage ;the average temperature from flowering to the ratooning buds ;sunshine time of the 3‐leaf to tillering and the accumulated temperature booting to heading stage > 0 ℃ .The integral regression and partial regres‐sion coefficient is made use of to analyze the influence of different developmental stages of meteorological factors on meteorological yield .The conclusion is drawn that the main meteorological factors affecting the yield were that average temperature a(t) value from sowing into the seedling is 236 .16 kg/hm squared ? ℃ ;the tem‐perature diurnal range a (t) value from booting to heading stage is 64 .73 kg/hm 2 ? ℃ .Secondly a(t) value from sowing to the seedling > 0 ℃ accumulated temperature is 34 .79 kg/hm squared ? ℃ .
