摘　　要：在高海拔山区缓坡地,选择不同杂交玉米品种(组合)进行栽培技术试验,结果表明,施氮方式对杂交玉米产量影响显著,平展型和半紧凑型玉米在追肥2次以上均能发挥增产潜力;半紧凑型新组合安2032在种植密度较高(4 000株/667m2)、追施3次氮肥的条件下,产量最高(701 kg/677 m2)。安2032新组合对缓坡地有较强的适应性和丰产性。Different hybrid maize varieties were tested on the flat sloping fields in mountainous areas with high elevation to study its cultivation technique for high yield. The results showed that the applying nitrogen pattern had the important effect on maize yield. The yield of maize varieties with loose and semi-tight plant type rose under the condition of over 2 times of top application. The yield of An 2032 with semi-tight plant type could reach 701 kg/677m^2 under the cultivation condition of 4000 plants/667m^2and three times of top application, which expresses An 2032 has the strong adaptability and yielding ability when it is planted on the flat sloping fields.
