【摘要】 利用棉花花铃期作物冠层和农田土壤小气候观测资料分析研究了棉花群体内温度、湿度和风速的时空变化规律，探讨了叶片水势、空气饱和差和冠层净辐射之间的关系，对土壤温度和土壤热通量的变化也进行了客观分析。更多还原

【Abstract】 Research and analysis were made to show variations of temperature,humidity and wind speed with time and height in cotton community according to field observations.The relationships were revealed among net radiation of canopy,leaf potential and saturated air vapor pressure deficit. Besides,daily courses of soil temperature and thermal flux were also studied.更多还原
