冬春麦兼种的宁南山区,屬于西北晚熟冬麦的交界地帶,冬小麦播种面积約40～50万亩,占小麦播种面积的25.2～26.5％。主要分布在气候温暖,雨水較多的固原城陽、头营,隆德沙塘、川道及泾源一帶,其他地区仅有零星种植。从历年冬麦产量情况看,在秋墒好及良好越冬的情况下,其产量高于春小麦12％左右。如固原城陽,隆德沙塘等地,一般亩产80～150斤,最高可达491.5斤;固原城关、头营、三营等地区,秋雨多的年份,产量高,旱地亩产70～120斤,最高

The winter and spring wheat are all kinds of Ningnan mountainous areas and belong to the junction zone of northwest late winter wheat and winter wheat.
