香菇冬季发菌微环境差异分析OA

The microenvironment of winter ruanning was analyzed for Lentinula edodes cultivation,based on three ventilation types of the running plastic house,typeⅠ,axial-flow fan with bottom ventilation;typeⅡ,distributed fans with top ventilation;type Ⅲ,manual regulation without ventilation facilities.The microenvironment effect is investigated by the temperature,relative humidity of atmospare in the whole running period for clearing environment parasites of the Lentinula edodes running in winter.The results showed that environmental uniformity differs in the ventilation types.The different ventilation types affected the temperature and the relative humidity of atmospare in the plastic house.The running could be divided into the early stage,middle stage and late stage according to the characteristics of temperature and relative humidity in whole period.Therefore,the running management strategy should be proposed based on this investigation and analysis,including regulating environment depend on running stages,co-control of fan-opening depend on multi-point temperature,adding vertical and horizontal flow disturbance facilities,increasing turning times,and making significant lower temperature and humidify before and after punching for increase oxygen.This study will provides support for the running management for Lentinula edodes in winter.
