项目摘要

Sufficient initial studies of the optimum growing conditions for mushroom farming have been made at the growing site. However, their scientific investigations need continuous updating. In this study, using bio-electric potential as an indicator, being closely related to the activation of mushroom growth, scientific studies of the optimum growing conditions have been made, in addition to the studies of the relationship between illumination or morphogenesis. This lead to the fabrication of an innovative light source for control of farming. Furthermore, by observing autonomous bioelectric potential signals, which accompanied the biorhythms of mushrooms, we discussed a farming technique, using the biorhythm as a biosensor to control the environmental light stimuli of the mushrooms. In addition, we succeeded in the non-destructive photography of the development of fungal threads in the medium using MRI. The relationship between the growth of the fruit bodies on the ground and fungal threads … More in the subterranean was discussed. The following is a detail of the technical development :(1)Additional production of a precise auto-measurement system for bioelectric potential.Using the knowledge gained from the fabricated equipment, an automatic system was produced for the measurement of the bioelectric potential, resulting from programmable air components or light stimuli.(2)Using a SQUID, an ultra-faint magnetic field signal was measured in the mushroom fruit body.The measurement of the ultra-faint magnetic field signal of mushroom, self-induced by light stimuli, was measured at the levels of from fT to pT and its application was investigated for the analysis of the physiologically active conditions and health diagnostics of the mushrooms.(3)Practical use of light source equipment, aiming at the optimum farming conditions, using the mushroom itself as a biosensor.Observation of the biorhythm of a specific mushroom, using it as a biosensor to control the duration of light and dark of light stimulation of the surrounding mushrooms.(4)Three-dimensional display of the development of fungal threads using MRIUsing MRI, we have succeeded in generating a non-destructive display of a tomograph of fungus for a period covering the initial planting of the fungus up to the dispersal of spores from the fruiting body.(5)Practical use of light sources at a mushroom farmA light source system was fabricated, based on the results obtained from mushroom farming in a Growth Chamber in the laboratory. Then, in order to evaluate the effectiveness of the system.(6)othersThe possibility of growth control by continuous application of a direct current field to mushrooms was discussed. The bioelectric potential response was investigated with regard to the magnetic field, together with MRI studies of the effects on the fungal growth in the culture medium. Less

对蘑菇种植的最佳生长条件进行了充分的初步研究。然而，他们的科学研究需要不断更新。本研究以与蘑菇生长激活密切相关的生物电势为指标，在研究光照与形态发生关系的基础上，对蘑菇生长的最佳条件进行了科学的研究。这导致了一种用于控制农业的创新光源的制造。此外，通过观察伴随蘑菇生物节律的自主生物电电位信号，我们讨论了一种耕作技术，利用生物节律作为生物传感器来控制蘑菇的环境光刺激。此外，我们成功地利用MRI对培养基中真菌丝线的发育进行了无损摄影。讨论了地下真菌丝线与果实在地上生长的关系。以下是技术发展的细节：(1)额外生产精确的生物电势自动测量系统。利用从制造设备中获得的知识，生产了一个自动系统，用于测量由可编程空气组件或光刺激产生的生物电势。(2)利用SQUID测量了蘑菇果体内的超微弱磁场信号。在fT ~ pT水平上测量了光刺激下蘑菇自生的超微弱磁场信号，并探讨了其在蘑菇生理活性状况分析和健康诊断中的应用。(3)实际使用光源设备，针对最佳养殖条件，利用蘑菇本身作为生物传感器。观察特定蘑菇的生物节律，用它作为生物传感器来控制周围蘑菇的光刺激的光和暗的持续时间。(4)利用核磁共振成像技术对真菌丝线发育进行三维显示利用核磁共振成像技术，我们成功地生成了一段时间内真菌的非破坏性断层摄影图，涵盖了真菌最初的种植直到孢子从子实体扩散。(5)光源在蘑菇养殖场的实际应用根据实验室生长室中蘑菇养殖的结果，制作了一个光源系统。然后，为了评价系统的有效性。讨论了连续施加直流电场控制蘑菇生长的可能性。研究了磁场对生物电势的响应，并对培养基中真菌生长的影响进行了MRI研究。少
