摘　　要：以张掖市甘州区为试验地点,选用4个不同玉米品种为研究对象,设置3个不同种植密度,对不同种植密度下玉米的农艺性状、产量和倒伏情况进行评估,比较不同种植密度对不同品种玉米农艺性状、产量和抗倒能力的影响。结果显示,种植密度为6.00×10^(4)株/hm^(2)时,有利于提高正德305和华农887这2个品种的产量;种植密度为8.00×10^(4)株/hm^(2)时,有利于提高优玉68和优玉20这2个品种的产量和抗倒伏能力。Taking Ganzhou District of Zhangye City as the test site,4 different varieties of maize were selected as the research objects,and 3 different planting densities were set up to evaluate the agronomic traits,yield and lodging of maize with different planting densities,and compare the effects of different planting densities on agronomic traits,yield and fall resistance of different varieties of maize.The results showed that when the planting density was 6.00×10^(4) plants/hm^(2),the yield of Zhengde 305 and Huanong 887 maize varieties could be improved.When the planting density was 8.00×10^(4) plants/hm^(2),the yield of two varieties of Youyu 68 and Youyu 20 and the lodging resistance of four varieties of maize were improved.
