山西中部晚熟冬麦区,是我省分布范围较广,所处生态环境最复杂的麦区。由于地形复杂,气候多变,耕作制度、栽培水平各异,所以品种生态类型比较复杂。以晋中区为例:据1981年普查,生产上栽培的品种达251个。品种的冬春性,从强冬至弱冬均有,尽管品种数量多,类型复杂,但当家品种却比较集中。 Late Shanxi Zhongmai winter wheat area, is a wide range of distribution in our province, where the ecological environment of the most complex wheat area. Due to complex terrain, changing climate, tillage system, different levels of cultivation, so the species more complex ecological type. Take Jinzhong District as an example: According to the 1981 census, 251 varieties were cultivated in production. Winter and spring varieties, from strong winter solstice weak winter, despite the large number of species, the type of complex, but when the species are more concentrated.
