摘要 通过在青海省贵南县草业公司一分场、二分场、三分场3个青稞种植基地选择条件相近的地段，同一日播种，并用相同的农事技术种植同一品种有机青稞，采用农业气象方法观测气象条件对有机青稞的影响。结果表明，一分场在热量条件中优于二分场和三分场；2015年6月上旬、7月中旬—下旬和8月中旬—下旬，土壤水分对有机青稞均不利。产量，一分场地段最高，接近普通青稞本年度平均产量，经济效益远高于普通青稞，在贵南县城所在地与一分场气候条件相近的地区，可以提前播种期15 d左右，大面积推广播种有机青稞，提高经济效益。

Abstract In Guinan grassland industry company，through first sub-field， second sub-field， third sub-field three barley planting base selection conditions similar to the lot， the same day sowing， and with the same agricultural technology to grow the same species of organic barley，the influence of meteorological conditions on organic barley was observed by agricultural meteorological method.The results showed that the first sub-field was better than second sub-field and third sub-field in the heat conditions. In early June， mid July to late July，mid August to late August，soil moisture was not good for organic barley.Production， the first sub-field was the highest and close to the average annual production of ordinary barley， the economic benefits was much higher than the ordinary barley.In the county town of Guinan and third sub-field climate conditions similar to the area can advance sowing about 15 d， large area to promote planting organic barley and improve economic efficiency.

生長在青藏高原的高寒作物青稞，具有生长周期短、耐寒、抗旱和产量高等特点[1]。青海省贵南县地区气候适宜青稞的生长，作为特色农业，有着大面积种植传统。但生育期内光热水气象要素的分配不均，易发生干旱、霜冻、高温热害等灾害，这使农户在种植时大量使用化肥，以肥养田来提高产量。近年来，贵南县以创建青海省首家国家有机产品认证示范县为契机，大力推进生态保护-种草养畜-农畜产品加工-有机肥还田的农牧业循环经济，借助青海互助青稞酒股份有限公司在贵南县建立有机青稞酒原料大基地的有利时机，在贵南草业公司积极建立了没有任何污染的6 160 hm2有机青稞种植基地，发展有机青稞的种植产业。……
