摘要
在湖北省荆州市对春季晴天塑料大棚内不同位置的小气候进行了分析研究。结果表明:大棚内的光照强度从10:00到16:00均显著低于露地对照,早上8:00棚内除北点显著低于对照外,包括晚上18:00,与对照差异不显著;棚内南北中3点从早到晚光照强度差异不显著;从10:00到18:00,大棚内的温度显著高于露地对照;从早到晚,除10:00、12:00大棚内中点和南点的温度差异显著外,其他时间点大棚内不同位置的温度无显著差异。大棚内的湿度从北到南逐渐降低,且差异显著。从早到晚,塑料大棚内光照强度和温度的变化趋势均为先升高再降低,而大棚内湿度变化趋势是先降低后升高。
The microclimate of different positions within plastic shed in sunny day during spring in Jingzhou City,Hubei Province was analyzed.The results showed that from 10:00 to 16:00 the light intensity in shed was significantly lower than thar of outdoor.In addition to north point it was significantly lower than the control at 8:00,including 18:00,which was no significant difference compared with the control,and from morning till night,the light intensity in shed in the north,south and in the middle position had no significant difference.From 10:00 to 18:00,the temperature in the shed was significantly higher than that of the outdoor.From morning till night,the temperature had no significant difference from the different positions in the shed,in addition to the temperature in the mid-point and the south-point being significant difference at 10:00 and 12:00.But from north to south,the humidity in the shed decreased gradually,and the difference was significant.From morning till night,the change of light intensity and temperature in the plastic shed rised first and then reduced,and the change of humidity in the plastic shed reduced first and then increases.
