夏季高温是导致食用菌日光温室出现高温高湿环境的主要原因,该环境不利于食用菌的生长,针对此问题,以沈阳市某一杏鲍菇养殖日光温室为研究对象,首先建立几何模型;其次在建立太阳辐射模型时考虑了散射辐射,并以云遮系数法辐射强度进行修正,将计算结果作为日光温室热环境模拟的输入参数,建立了夏季典型日的日光温室CFD模型;最后将所建立的模型模拟结果及未经修正太阳辐射模型的模拟结果与实测结果进行对比,所建立模型的温度和相对湿度的平均相对误差分别为 4.3%和 5.0%,未经修正太阳辐射模型的温度和相对湿度的平均相对误差分别为 4.8%和 5.3%,这表明所建立太阳辐射模型提升了热湿环境模拟的精度.此外,通过模拟温室内的气流组织设计,证明即使在夏季极端气候,也能保证杏鲍菇处于适宜生长的温湿度范围之内,进而证明了可以通过空调调控使日光温室达到食用菌适宜生长的环境.
Study on the Environmental Suitability of Summer Culture in Edible Mushroom Solar Greenhouse
The high temperature in summer is the main reason for the high temperature and high humidity environment in the edible mushroom solar greenhouse,which is not conducive to the growth of edible mushrooms.Secondly,the scattered radiation is considered in the establishment of the solar radiation model,and the radiation intensity is corrected by the cloud occlusion coefficient method,and the calculated results are used as the input parameters for the simulation of the thermal environment of the solar greenhouse,and the CFD model of the solar greenhouse on a typical day in summer is established.Finally,the average relative errors of temperature and relative humidity of the established model and the unmodified solar radiation model are 4.3%and 5.0%,respectively,and the average relative errors of temperature and relative humidity of the unmodified solar radiation model are 4.8%and 5.3%,respectively,which indicates that the established solar radiation model improves the accuracy of thermal and humid environment simulation.In addition,by simulating the airflow organization design in the greenhouse,it was proved that even in the extreme climate of summer,it was proved that the temperature and humidity range suitable for the growth of Pleurotus eryngii could be ensured,and then it was proved that the solar greenhouse could be controlled by air conditioning to achieve a suitable environment for the growth of edible mushrooms.
