我国栽培大麦已有悠久的历史,由于大麦的生育期短,分布的地区极为广泛,北纬52°的黑龙江北部、海拔4,400公尺的康巴宗都有大麦或青稞的分布。而且我国地域辽阔,地势、土壤、气候及耕作制度极为复杂,经过长期的自然选择及人工选择,产生了大量适应于不同地区栽培的大麦地方品种。过去对我国大麦品种的分布,尚无系统的研究,因此根据各个品种的性状总体和原产地的综合环境条件关系,把全国大麦品种归纳为若干生态类型,使其既能反映各个地区的自然条件和耕作制度,又能反映出适应各个不同地区的品种的基本性
Barley has been cultivated for a long time in our country. Due to the short growth period of barley, the distribution area of barley is extremely wide. There is a distribution of barley or barley in the northern part of Heilongjiang at an elevation of 52 ° and at an altitude of 4,400 meters. Moreover, China has a vast territory with extremely complicated topography, soil, climate and farming system. After long-term natural selection and artificial selection, a large number of barley landraces adapted to different regions have been produced. In the past, there was no systematic study on the distribution of barley in China. Therefore, according to the relationship between the overall traits of each variety and the comprehensive environmental conditions of origin, the barley varieties in the whole country were classified into several ecological types to reflect the natural conditions of each region And cultivation system, but also reflect the basic nature of varieties adapted to different regions
