多年来,蘑菇的死菇问题一直十分突出。为了探明死菇的原因,并制订相应的防止对策,笔者进行了大量的调查研究和分析论证,认为:蘑菇子实体在形成与发育期间,伤热、伤水、伤气,伤风、伤寒是引起死菇,导致减产的主要原因。“五伤”引起死菇.可以是单因素作用,也可以是综合因素影响,但无论是单因素作用还是综合因素影响,透过蔚菇生产的各个环节来看,不外乎从两个方面反映出来;一是生产基础建设及环境因子的自控能力;二是管理水平及人为调节能力。只要有了这样的认识,就不难找到解决问题的途径和方法。防止“五伤”,减少死菇的主要对策有以下四点: 一,改善菇房的基本条件新建菇房必须按正规要求施工,增加墙壁厚度,完善通风设施。上中下窗、拔风筒配套,力求满足各生育阶段对空气的要求。实践证明,筑土墙,盖草顶的简易菇房具有投资小、建造方便、小气候稳定等优 Over the years, mushrooms mushroom problem has been very prominent. In order to find out the causes of dead mushrooms, and to formulate the corresponding countermeasures, the author conducted a large number of investigations and studies and analysis and argumentation, that: the mushroom fruiting bodies in the formation and development period, heat, water, gas, cold, typhoid fever is Caused by dead mushrooms, leading to the main reason for the cut. “Five injuries” caused by dead mushroom can be a single factor, it can be a combination of factors, but whether it is a single factor or a combination of factors, through the various aspects of the production of mushrooms point of view, nothing more than from two aspects Reflected; First, the production of infrastructure and environmental factors self-control capabilities; Second, management and man-made adjustment. As long as there is such an understanding, it is not hard to find ways and means to solve the problem. To prevent “five injuries”, the main countermeasures to reduce dead mushrooms have the following four points: First, to improve the basic conditions of mushroom house New mushroom house construction must be formal requirements, increase the thickness of the wall, improve ventilation. Upper and lower windows, pull the duct supporting, and strive to meet the requirements of the various stages of growth of the air. Practice has proved that earth-mural walls, cover grass roof simple mushroom house with a small investment, easy construction, stable microclimate, etc.
