Abstract: An experiment was conducted in a large-size banana-cultivation screen-house with 352 m ×228 m in Israel to study the distribution and changes of microclimate inside the screen-house and relationships of the microclimate between inside and outside.The results showed that the screen transmissivity decreased with experimental time increasing.The microclimatic variables inside the screen-house were linearly related to those outside.Inside the screen-house,the relative humidity was higher,vapor pressure deficit was lower,and wind velocity decreased greatly in comparison with those outside the screen-house,while the temperature difference between inside and outside the screen-house was small.The differences in relative humidity,temperature and vapor pressure deficit between inside and outside the screen-house decreased with the wind velocity increasing.Inside the screen-house,the vapor density around canopy was higher than those near ground surface,and the converse temperature distribution occurred.
