| 摘 要： | 根据日光温室内水汽质量动态平衡关系,同时全面考虑了作物蒸腾、土壤蒸发、覆盖层内表面凝结和闭膜后的冷风渗透等与湿度变化相关的各种物理过程,建立了温室空气湿度动态预测模型。通过冬季试验验证了模型的预测功能。结果表明:室内空气相对湿度动态预测模型连续日期的预测结果与实测值比较吻合,相关系数为0.897 5,相对误差平均值为9.45%。

| Abstract: | The dynamical forecast model of air humidity in sunlight greenhouse was established according to dynamical balance relations of waters steam quality in sunlight greenhouse and physical process related humidity changes such as crops transpiration,soil evaporation,surface congealment of internal overburden layer,and the cold wind seepage after plastic film closed and so on.The function of model forecast was confirmed through winter experiment.The result showed the forecast results of continual dates which were got from dynamical forecast model of air humidity in sunlight greenhouse tallied with actual values.The correlation coefficient is 0.8975,and the mean value of relative error is 9.45%. |
