曲沃县位于临汾盆地南端,地处北纬35°33′—35°52′之间,年均太阳辐射量为5.14×10~5焦耳/厘米~2。全年积温4815℃,无霜期185天,年降水量518毫米左右。土地肥沃,土壤多为壤质。滏河、浍河横穿东西,汾河流经高显、里村等乡镇,水利资源比较丰富。我们在这个县的下坞村进行了2年调查、试验,1989年搞了500亩高产示范田,平均亩产粮食1074公斤,其中小麦503公斤,玉米571公斤,实现了“吨粮田”目标。我们总结出“四化”栽培经验,即水分应用合理化,肥料施用科学化,栽培管理指标化,病虫防治规范化。
Quwo County is located in the southern tip of Linfen Basin, located between 35 ° 33’-35 ° 52 ’north latitude with an annual average solar radiation of 5.14 × 10 ~ 5 Joules / cm ~ 2. The annual temperature of 4815 ℃, frost-free period of 185 days, annual precipitation of about 518 mm. The land is fertile and the soil is mostly loamy. Ba River, Ba River cross something, the Fen River flows through the high significant, such as villages in the village, rich water resources. We conducted a 2-year survey and trial in the dock village of this county. In 1989, we engaged in a 500-acre high-yield demonstration field with an average yield of 1074 kilograms of grain, including 503 kilograms of wheat and 571 kilograms of corn, achieving the goal of “tons of grain” . We summed up the “four modernizations” cultivation experience, that is, the rationalization of water use, scientific application of fertilizers, cultivation and management indicators, standardization of pest control.
