	<span style=\"font-size:14px;\">本文利用2019年河北唐山大棚葡萄开花坐果期(3月29日至4月30日)共33天曹妃甸唐海镇农研所试验基地气象观测站及小气候站所观测的棚外相对湿度、1.5 m棚内湿度、棚内日照指数、棚外2分钟平均风速的资料，利用图表相关分析以及相关系数，分析了当地温室大棚对湿度的调控效果，并研究了其影响因子。结果表明：1) 白天大棚平均增湿11%，夜间平均增湿25.2%，日均增湿18.1%。每日增湿作用最强的时间多处在0:00~2:00，最强增湿作用平均为38.6%。每日增湿作用最弱的时间多处在9:00~13:00，最弱增湿作用平均为？1.3%。大棚对湿度的调控效果在0:00-7:00有较小波动但总体保持稳定，增湿作用平均保持在21.9%~25.1%。每日的7:00~9:00大棚的增湿作用迅速减弱。9:00~16:00达到最低为一天中最弱的时候，增湿作用平均保持在5.2%~9.5%，16:00~19:00增湿作用迅速增强，19:00后持续减弱。2) 大棚对湿度的调控效果与棚外相对湿度在白天呈中等程度的负相关，在夜间呈极强负相关；大棚对湿度的调控效果与棚外2分钟平均风速在白天呈正相关；在夜间呈弱的正相关；大棚对湿度的调控效果与棚内日照呈中等程度的正相关。<br />
By 2019, Hebei Tangshan greenhouse grape flower fruit data (March 29 solstice to April 30), a total of 33 days Caofeidian Tanghai Town Nongyansuo and microclimate testing ground meteorological observatory station observation of the relative humidity of bird, relative humidity of 1.5 m, relative index of sunlight, bird 2 minutes on average wind speed data, using charts, correlation analysis and related coefficient are used to analyze the local greenhouses humidity control effect, and its influence factors are studied. The results showed that: 1) The average humidity of greenhouses increased by 11% in the daytime, 25.2% at night and 18.1% in the average day. The time with the strongest humidification effect is mostly at 0:00 to 2:00 every day, and the average time with the strongest humidification effect is 38.6%. The time with the weakest humidification effect was from 9:00 to 13:00 every day, and the weakest humidification effect was ？1.3%. The humidity control effect of greenhouses fluctuated slightly from 0:00 to 7:00, but remained stable on the whole. The humidification effect was kept at 21.9% - 25.1% on average. Daily 7:00 to 9:00 greenhouses humidification effect rapidly weakened. When it reached the lowest point between 9:00 and 16:00, the humidification effect remained at 5.2% - 9.5% on average. The humidification effect increased rapidly between 16:00 and 19:00, and continued to weaken after 19:00. 2) The humidity control effect of greenhouses has a moderate negative correlation with the relative humidity outside the greenhouses in the daytime and a strong negative correlation at night. The humidity control effect of greenhouses was positively correlated with the 2-minute average wind speed outside greenhouses in the daytime, and there is weak positive correlation at night. The humidity control effect of greenhouses was positively correlated with sunshine in greenhouses to a moderate degree.</span>
