摘　　要：试验以基因型不同、表现型差异明显的两个玉米单交种进行2∶2和4∶4间种,研究其增产效应.试验结果表明：玉米不同品种合理间种可显著提高产量,但不同品种间种增产幅度不同,试验的3组搭配组合增产在4.56％～8.06％.对产量构成因素分析,认为合理间种后百粒重提高和穗粒数增加是其增产的两个主要因素.The test of increase yield was conducted by two different genotype and phenotype single-cross varieties interplanted at 2：2and 4：4. The results showed that the different maize varieties could significantly increase yield, but the increase rate of different varieties had different range, there increase yield of three combination of test was in 4.56 %-8.06 % . Analysis of factors on yield suggested that Hundred-grain weight and grain number of spike increased were two major factors of reasonable interplanting.
