摘要
研究表明，在新疆大陆性气候条件下，春小麦叶片的光合作用有明显的“午睡”现象。在光照、气温、ＣＯ２浓度和大气相对湿度等诸多生态因子中，大气相对湿度是引起“午睡”现象的主要生态因子。
Expriement shows spring wheat has an obvious phenomenon of middday depression of photosynthesis in Xinjiang typical continental climate in CO2 concentration,relative humiday, light intensity, air temperature etc ecological factors, the reative humidity is an important ecological factor in the middday depression and the change of net photosynthetic rate of spring wheat.
