地处塞外高寒地区的朔州市朔城区位于山西省北部,大同市西南端,属温带大陆性季风气候,无霜期130天左右,年平均气温6.8℃。年降雨最400～500mm。由于气温低,无霜期短,栽培技术落后,玉米单产长期徘徊在200～300kg之间。为了改变玉米的低产状况,近几年农技推广部门抓紧了高产综合栽培技术,1989年5万亩玉米单产突破550kg,获省科技进步三等奖。小平易乡1万亩玉米,夺得单产750kg的好收成。1991年全区实行技术承包,扩大推广面积,在小
Shuozhou City Shuo Cheng District is located in the northern part of Shanxi Province and the southwest end of Datong City. It belongs to the temperate continental monsoon climate and has a frost-free period of 130 days with an annual average temperature of 6.8 ℃. The annual rainfall of 400 ~ 500mm. Due to the low temperature, frost-free period is short, backward cultivation techniques, long-term yield of corn hovering between 200 ~ 300kg. In order to change the status of low yield of corn, in recent years, agricultural extension departments pay close attention to high-yielding integrated cultivation techniques. In 1989, the output of 50000 mu of corn exceeded 550kg, winning the third prize of science and technology progress. Xiaoping Yi Township 1 million mu of corn, won a good yield of 750kg yield. In 1991 the region to implement the technical contract, to expand the promotion area, small
