大麦为我国古老作物之一。由于大麦的生育期短,分布地区极为广泛。西起西藏高原,东至沿海地区,北起黑龙江,南迄广东都有栽培,而且各地区气候、土壤以及耕作栽培条件均有不同,经过长期以来自然选择及人工选择的结果,每个地区都形成了具有一定特点的大麦的生态类型。研究这些生态类型及其地理分布,对于我国各个地区大麦生产栽培对品种的基本要求,育种原始材料的合理利用,选种目标的确定以及引种调种等工作都具有重要意义。
Barley is one of the ancient crops in our country. Due to the short growth period of barley, the distribution area is extremely wide. From the Tibet Plateau to the east, from the coast to the north, Heilongjiang from the north and from Guangdong to Guangdong from the south, and the climate, soil and cultivation and cultivation conditions vary from region to region, and after long-term natural selection and manual selection, each region Formed a certain characteristics of the ecological type of barley. Studying these ecotypes and their geographical distribution is of great significance to the basic requirements of barley production and cultivation in various regions of our country, the rational utilization of breeding raw materials, the selection of breeding targets and the introduction and adjustment of seeds.
