大宁县位于晋西南吕梁山南部,境内沟壑纵横,地形复杂。旱塬、坡地占农业用地面积的85.8％。本县属暖温带半干旱气候,四季分明。冬季漫长,干燥寒冷,夏季水热资源比较丰富,秋季则秋高气爽,春季干旱多风。十年九旱。因而小麦产量长期低而不稳。为了改变这一低产面貌,进行了夏播小麦栽培试验。在八个公社十二个大队,根据海拔高度和土地类型,试种夏小麦十四个点,供试品种晋春三号,于七月十日播
Daning County is located south of Luliang Mountain southwest of Shanxi, ravines in the territory of vertical and horizontal, complex terrain.
