Forecasting Model of Humidity in Chinese Solar Greenhouse in the North Drought Cold Area and Experiment in Winter

Abstract:

Based on the research results of light environment and thermal environment model and the principle of mass balance, the dynamic forecasting model of Humidity in Chinese solar greenhouse in the north drought cold area was established. The influenced factors correlative with water vapor change such as crop transpiration, soil evaporation, covered material condensation and natural or winded of closed situation ventilation were included in the model. To validate the correctness of the model, an experiment was carried out in the Chinese solar greenhouse in the Inner Mongolia agriculture science and technology park. The results showed that the inner relative humidity forecasted agreed well with the measured data in the north drought cold area in winter, and the relative error is less than 10%.
