Study and Design of SolarIlluminated Artificial Phytotron

Fully utilizing the sunlight and cold resources, this solarilluminated artificial phytotron consists of a culture chamber, an energy supply part and a control system which uses digital meters and electronic techniques to achieve an accurate and precise control of temperatures,illumination and humidity.The phytotron,controlling the air and soil temperatures respectively,is especially applicable to those experiments that require different temperatures in chamber air and in the soil under the condition of natural illumination.The phytotron is characterized by the energysaving,the low investment and the less operation cost.
