| 摘 要： | 在下雪、阴天、晴天、多云4种天气下，研究了5种保温材料对大棚条件下小拱棚内温度的影响。结果表明，有膜无纺布（40 g•m-2）+薄膜的保温效果最好，对照塑料膜处理的温度变化幅度较其他处理大，保温效果最差；土壤温度的变化相对气温变化具有滞后效应；土层越深，土壤温度的变化越滞后；土壤浅层温度变化急剧，随着土壤深度的增加温度变化趋于平缓；土壤各层最高温度出现的时间随土层深度的增加而延迟

| Abstract: | Effects of 5 thermal conservation materials in the small plastic shed under 4 different climate conditions: snowing, overcast, sunny and cloudy were studied. The results indicated that the different thermal conservation materials have remarkable effects on the temperature in the small plastic shed. Compared with other treatments, the non-woven fabrics with film, type of the 40 g•m-2 had the best effect in maintaining inner temperature, and the CK (PVC) had the worst. Compared with air temperature, soil temperature changed more slowly during one day. The deeper soil layer, the slower soil temperature changed, but in the shallow soil layer, the sharper temperature changed. Soil temperature changed slowly along with the increasing of soil depth. The time for the highest temperature appearance in various soil layers will delay along the increase of soil depth. |
