    摘要:

    在2種通風率和濕簾開,、關狀況下對溫室內(nèi)部氣候相關參數(shù)進行了檢測和對比分析,并重點對蒸騰速率進行了模擬計算和測量,。試驗結(jié)果表明:蒸騰速率與通風率,、濕簾工作狀況相關,,在相對干燥的環(huán)境下(不開啟濕簾),,提高通風率可使植物獲得更大的蒸騰量,,從而可使溫室內(nèi)部溫度不超過室外溫度,。在濕簾不工作的情況下,由于蒸騰的作用植物葉面溫度低于周圍的環(huán)境空氣溫度,;而在濕簾工作情況下,,室內(nèi)濕度較高,蒸騰受到抑制,,葉面溫度高于周圍環(huán)境空氣溫度,。

    Abstract:

    For a comprehensive understanding of climate in a greenhouse with fan and pad system, an experiment measuring climate parameters was conducted on with two ventilation rates and with pad on and off. The transpiration rate of the plant inside greenhouse was supposed to be one of the most important factors on climate considerably influences latent heat exchange, and it was calculated and measured mainly in this work. The experimental data show that the transpiration rate has some correlation with ventilation and pad working condition. In the case of no pad working, the higher ventilation which promotes transpiration will induce a lower temperature inside greenhouse to outside and a lower leaf temperature than its ambient temperature. But with the pad working the leaf phenomena is just opposite. The vertical and horizontal distribution of temperature and specific humidity were also measured and analyzed.
