Study of SPA Cultivation Control System Based on Bio-Electric Potential Feedback from Mushroom

本研究探讨了构建SPA （Speaking Plant Approach）栽培控制系统的基础知识，取得了以下成果：对果体进行了远红外照射和中、近紫外电压照射试验，验证了其有效性。同时也证实了以核磁共振弛豫时间作为生长评价手段的成分分析的有效性。在此基础上，结合前人的研究成果，构建了基于蘑菇生物电势自动控制环境促进生长的新型栽培系统。该系统已在香菇厂实际安装，并根据试验结果进行了改进。

In this study, basic knowledge for construction of SPA (Speaking Plant Approach) cultivation control system was explored and the following results were obtained.Far-infrared irradiation and voltage application to medium and near ultraviolet irradiation to fruit body were tried and their validity was confirmed. Validity of component analysis with relaxation time of NMR as growth evaluation means was also confirmed.Based on the results and previous results, new type cultivation system to control environment automatically for growth promotion based on the bio-electric potential of mushrooms was constructed. The system was actually installed in mushroom factory and was improved based on the test results.
