摘    要:根据观测资料,分析了塑料大棚的温度,相对湿度和风速的变化规律。结果表明,9:00 ̄11:00时塑料大棚内外的气温差增大,其差值随高度升高而增加,棚内气温呈逆温分布,相地显度棚内比棚外平均高17.8%,塑料大棚通风时,棚内风速仍小于棚外,而且棚内中心比棚内四周边缘的风速小,自然通风调节棚内的温度,湿度,约需3 ̄4h小时。

关 键 词:温度 湿度 风速 塑料温室 小气候

Abstract:According to observational data, the paper analyzed variation laws of the air temperature, relative moisture and wind speed in plastic greenhouse.At 9:00~11:00, temperature difference between inside and outsid was increased along with the increase of height.Temperature was inversion distribution inside the plastic greenhouse.The mean relative humidity of inside was more 17 8% than that of outside the plastic greenhouse.During winding time, the average winde speed inside plastic greenhouse was less than that of outside.In the plastic greenhouse, the wind speed of median was less than that of the around.It needed 3~4 h to regulate the temperature and the relative humidity by means of natural draft.
Keywords:Plastic greenhouse  Temperature  Moisture  Winde speed
