网室内外气象要素的变化特点
摘要为了解网室与自然环境中气象要素的差异,在网室内外的同一垂直高度平行观测了空气温度、空气湿度、光照强度、和风速。结果表明:网室内外空气温度、空气湿度的日变化不明显,网室内外光照强度、风速的日变化较大,网室内的光照强度、风速均比网室外偏低。网室内外月平均空气温度、月平均空气湿度的变化较明显,夏季网室内的月平均空气温度偏低,月平均空气湿度偏高;网室内外月平均光照强度、月平均风速差异较小,网室内的月平均值比网室外的偏低。结论:网室能起到减缓风速,减弱光照,改变空气温度、湿度的小气候效应。

Abstract:In order to understand the nets room with the natural environment in the difference of meteorological elements, in the same vertical height of indoor and outdoor net parallel to the observation of the air temperature, air humidity, light intensity, and wind speed. The results show that the nets indoor and outdoor air temperature, air humidity, the change is not apparent, nets indoor and outdoor light intensity and speed of the changes, bigger, nets indoor light intensity, wind speed are better than nets outdoor low. Nets indoor and outdoor air temperature, the average monthly average monthly air humidity change is more apparent, summer nets indoor month average air temperature is low, on average air humidity is on the high side; Nets indoor and outdoor month average light intensity, wind speed on average little differences, nets indoor month than nets outdoor low average. Conclusion: nets room can have slow wind speed, abate illumination, change in the air temperature, humidity microclimate effect.

网室是近年来在以色列和一些地中海国家发展起来的一种农业栽培设施,主要使用在辐射强度大、降水量小的区域,栽培作物以高附加值农作物和花卉为主[1,2],网室结构与温室相似,不同之处在于网室顶部的覆盖材料为遮阳网或防虫网[3-5]。国内对温室内的小气候条件、温室内作物生长模拟等做了大量的研究[6-8],但是由于经济条件、气候环境、种植结构和模式等原因,中国的网室种植面积较小,有关网室内小气候条件及作物生长、耗水等方面的研究也较少。作物的生长状况、耗水量等与气象要素紧密相关。对塔里木大学植物科学学院农业试验站作物栽培网室主要农业气象要素观测试验的研究,正是顺应经济与时代的发展,填补了阿拉尔市农业设施种植结构中网室研究的空缺。给人们以
