中文摘要	根据农田小气候观测资料分析了冷型小麦"陕229"和暖型小麦"NR9405"所形成的农田小气候特征及其成因.结果表明,在一定范围内,与暖型小麦"NR9405"相比,冷型小麦"陕229"灌浆结实期间的株间气温偏低0.5～2.3℃,0～0.2 m土层温度偏低0.3～4.0℃,株间水汽压和相对湿度分别偏高30～180 Pa和1%～10%,株间光照度偏小0.52～7.08 klx,且株间气温差及土壤温差随生育期推迟增大.即冷型小麦对高温干旱的适应性较暖型小麦强,且气候愈干燥、气温越高冷型小麦所表现出的田间小气候环境较暖型小麦越冷湿,这对干旱区半干旱区的小麦生产具有重大意义.
英文摘要	Based on observed data from farmland microclimate in dry shed, the farmland microclimatic characteristics and it’s forming causes of different-type wheats are analyzed. The results showed that the air temperature in row and soil temperature in 0～0.2m of "Shaan 229" are 0.5～2.3℃ and 0.3 -1.0℃ lower than those of "NR9405"respectively in a certainty range. The illuminance in row of cold type wheat "Shaan 229" in row is 0.5～7.0klx lower than that of warm type wheat "NR9405" in during milk-filling and burliness stage, the water-vapour pressure and the relative humidity are 30-180Pa and 1%～10%higher than those of "NR9405", also the air temperature and soil temperature are higher while the upgrowth delay . In other word, the cold type wheat’s adjustability is better than that of the warm type wheat, also climate is drier and air temperature is higher, the cold type wheat takes on advantage in farmland microclimate than that of the warm type wheat, these have a great meaning for wheat production in arid and semiarid areas.
