摘　　要：以郑单958为试材,研究了不同密度和行距配置方式下玉米产量变化规律。结果表明:不同行距间、不同密度间及不同行距与密度互作间产量均存在极显著差异,适度增加密度可以提高产量,随行距的扩大产量有降低的趋势,对紧凑型玉米而言,产量不仅与种植密度密切相关,而且与种植方式也有一定关系。Zhengdan 958 was used as materials to study on the Yield of corn under the different density and the row spacing, the results showed that： The different row spacing and the different density and their interaction make the output to have the very significant differences, Moderately increase the density can increase production, It has falling trend of the yield when expending the row spacing, The yield of erectophile type corn was not only related to planting density but also to the methods of cultivation.

关 键 词：玉米 紧凑型 密度 行距
