国营灵武农场,地处县城西北,黄河灌溉,土地大部介于湖田与高田之间,历年种植粮食作物以小麦为主,每年约8,000～10,000亩.从1964～1972年该场历年小麦平均单产和气象资料分析中发现,春小麦单产不仅与土地、肥料、品种、田间管理水平、病虫害等因素有关,而且与气温有着密切的关系. The state-owned Lingwu Farm is located in the northwest of the county and is irrigated by the Yellow River. Most of the land is between Hutian and Gaotian. The main crops are wheat, with an annual output of about 8,000 to 10,000 mu. From 1964 to 1972, Yield and meteorological data analysis found that spring wheat yield is not only related to land, fertilizers, varieties, field management, pests and diseases and other factors, but also has a close relationship with the temperature.
