遮雨棚设施结构对枣园温湿度的影响

笔者以7年生-10年生壶瓶枣树为试材，研究了遮雨棚栽培与大田栽培条件下温湿度变化规律和差异。结果表明：遮雨棚在晴天高温时有降温的作用，而阴雨天温度较低时则有保温的作用；遮雨棚阻碍了水分蒸发，使得相同条件下棚内湿度高于棚外；雨后棚内与棚外温度变化趋势基本一致，棚外湿度变化剧烈，棚内较为缓和。

Influence on Temperature and Humidity of Jujube Orchard with Canopy Structure

7 -10 years Huping tree as experimental materials, the temperature and humidity change rule and differences under the culture condition with canopy and field cultivation were studied. The results showed that the canopy had sunshade and cooling effect at high temperature in sunny day and had the effect of heat preservation at low temperature in rainy day; canopy hindered the moisture evaporation to make the humidity higher in the canopy than out of canopy in the same condi- tions ; the temperature in the two conditions had similar trend. After the rain, while the humidity out of the canopy changed severely and humidity in the canopy changed relative alleviatly.
