南宁地区位于广西的西南,温光充足,年平均降水量多达1100—1200毫米,但由于受季风的影响,雨量分布不均,春秋两旱常有发生。据不完全统计,1980年—1990年,全地区春玉米平均每年受旱面积达45.43万亩,约占播种面积的29.4％;秋玉米受旱面积16.65万亩,占播种面积的51.58％。为探索玉米抗旱栽培技术,1988年以来,南宁地区
Nanning is located in the southwestern part of Guangxi with ample temperature and light rainfall and an average annual rainfall of up to 1100-1200 mm. However, due to the monsoon, rainfall is unevenly distributed and spring and autumn and drought often occur. According to incomplete statistics, from 1980 to 1990, the annual average area of spring maize in the whole region reached 454,300 mu, accounting for 29.4% of the sown area; and the area suffering from drought in autumn maize was 166,500 mu, accounting for 51.58% of the sown area. To explore the corn drought cultivation techniques, since 1988, Nanning area
