| 摘 要： | 根据旱棚内外农田小气候观测资料,分析了冷型小麦“陕229”和暖型小麦“NR 9405”的农田微气象特征及其成因。结果表明,与暖型小麦“NR 9405”相比,冷型小麦“陕229”灌浆结实期间的株间气温、地温均偏低,株间水汽压和相对湿度升高,株间光照度减小。该结果说明,冷型小麦对干旱的适应性较暖型小麦强。

| Abstract: | Based on observed data from farmland microclimate in dry plastic shed,the farmland microclimatic characteristics and the causes are analyzed.The results show that the air temperature,soil temperature and the illuminance in row of cold type wheat "Shaan 229" are lower than those of warm type wheat "NR9405" during milk-filling and burliness stage.The water-vapour pressure and the relative humidity are higher than those of "NR9405".In other word,the cold type wheat adapts to drought better than the warm type wheat. |
