春小麦耗水量研究,整个试验设在定西县地区农科所网室中。定西县年平均降水量为425.1毫米,年平均气温为6.3℃,≥10℃的积温是2528.3℃,年日照时数2228.3,基本上能代表中部地区,特别是半干旱地区的气候生态特点。春小麦是该区的主要夏粮作物,占粮食作物总面积的35—40％。农业生产主要是旱农耕作,产量低而不稳,水分是农业生产上的主要限制因子。所以研究了解春小麦生育期的耗水规律对分析春小麦生产中存在的问题,从而
Spring wheat water consumption research, the entire experiment located in Dingxi County Regional Institute of Agricultural Network. Dingxi County, the average annual rainfall of 425.1 mm, the annual average temperature of 6.3 ℃, ≥ 10 ℃ accumulated temperature is 2528.3 ℃, the annual sunshine hours 2228.3, basically representative of the central region, especially the semi-arid climate and climate characteristics. Spring wheat is the main summer crop in the region, accounting for 35-40% of the total area of food crops. Agricultural production is mainly dry farming, with low and unstable yields, and moisture is the main limiting factor in agricultural production. Therefore, the study to understand the law of spring water consumption during the growth of spring wheat production in the analysis of the problems that
