- 摘要:对12 m 跨日光温室内纵向及横向湿度分布进行了测试分析。测试结果显示揭帘后温室纵向从西向东的三个测点达到最低相对湿度的时间分别相差2 h , 量值上为中部低、两侧高;温室横向从北向南四个测点中北测点达到最低湿度的时间比最南侧点提前1~ 2 h , 但在量值上呈现出中部两测点值低、南北两测点值高的特点。夜间盖帘后, 各测点相对湿度均大于85%, 最南侧测点(接近薄膜)为100%, 各点的湿度从北向南逐渐增加, 在所选晴天中0∶00~ 8∶00各点平均相对湿度最大相差6~ 10 个百分点;16∶00~ 23∶00 各点平均相对湿度最大相差9~ 11 个百分点。
- Abstract:
- Lognitudinal and transverse humidity distributions were measured inside a 12 m span solar g reenhouse.Resultsshowed that a 2 h time-lag occur red between the three measure points fo r approaching the lowest humidity from the west tothe east when the co tton cover rolled with the data lower in the middle and higher in two ends.Transversely , the lowest humidityoccurred at the northern point 1 ~ 2 h prio r to the southern point with the data lower in the two middle pots andhigher at two side pots.Relative humidity of all pots was over 85% when co tton cover unrolled during night with the valuereaching 100% near south roof .The average relative humidity difference reached as large as 6~ 10 percent point during 0∶00~ 8∶00 and 9~ 11 percent point during 16∶00~ 23∶00 from the north to the south in selected clear days .
