| 摘 要： | 用CB-0241型红外测温仪研究了玉米灌浆期间气冠温差与产量的关系.结果表明,在玉米灌浆期间,两个密度下的玉米品种气冠温差都随生育进程呈现升—降—升—降的趋势,并且6×104株.hm-2种植密度的玉米品种在吐丝后20 d左右和35 d到成熟这两个阶段的气冠温差与产量之间具有很好的相关性.

| Abstract: | The relationship between temperature difference between canopy temperature at grouting stage and air temperature and yield was researched by a CB-0241 infrared thermometer.The results showed that the temperature difference between canopy temperature(Tc) and air temperature(Ta) had a trend of high-low-high-low in two densities.Moreover, for the high planting desity genotype maize,it showed a good correlation between Ta-Tc and the yield around 20 days and from 35 days to after silking maturity stage. |
