糜子是固原县主要秋粮作物之一,种植面积约36万亩,占秋粮总面积34%,主要分布在北部干旱和半干早区,阴湿区种植较少。从本县气候条件来看,比较适宜种植糜子,但往往不能稳产高产,有的年份亩产可收100多斤,有的年份只有20来斤。从农业气象角度分析,主要是水热因子制约着糜子的产量高低。 Millet is Guyuan County, one of the main autumn crops, planting an area of ​​about 360,000 mu, accounting for 34% of the total area of ​​autumn grain, mainly in the northern arid and semi-dry areas, humid areas less planted. From the county’s climatic conditions, more suitable for the cultivation of millet, but often can not be stable and high yield, and some years can receive 100 kilos per mu, and some years only 20 pounds. From the perspective of agricultural meteorology, mainly the hydrothermal factor restricts the level of production of millet.
