摘 要:以玉米隆平206为试验材料,设行距为50cm、60cm、70cm、80cm的四种种植方式,研究了不同行株距配置对夏玉米产量及田间小气候的影响。结果表明,行距对产量有显著影响,行距为50cm时产量最高,行距对田间小气候下的日平均温度、相对湿度、日平均光强、日平均风速有显著影响,随着行距增大日平均温度和相对湿度逐渐减小,日平均光强和日平均风速逐渐增大。各气候因子对产量的影响不同,相对湿度和产量的关联度最大,对产量影响最大。50cm行距配置可有效协调群体内各气候因子之间的矛盾,产量最高。In order to characterize the effect of row spacing on maize yield and field microclimate, four treat- ments, row spacing of 50cm, 60cm, 70cm, 80cm were arranged in this experiment, using Longping206 as material. The results showed that maize yield was highly significantly influenced by row spacings, and the yield of 50cm- row- spacing is the highest. Daily mean temperature, relative humidity, light intensity and wind speed in maize field were significantly influenced by row spacings. With the row spacing increasing, daily mean temperature and relative humidity decreased gradually, and daily mean light intensity and wind speed increased. The effect of each climatic factor on yield is different. Relative humidity had the biggest correlation with yield, and its effect on yield was the greatest. The study showed that row spacing had coordinated function on maize yield and field microclimate. With a row spacing of 50cm, contradictions between each climate factor could be effectively coordinated, and 50cm - row - spacing could lead to the highest yield in all treatments.
