沼气不仅是一种生物质能源,而且也是一种环境气体调制剂,可用于粮食、种子的贮藏和水果、蔬菜的保鲜。沼气贮粮,是一项简便易行,投资少,经济效益显著的实用技术。一、作用机理沼气是由厌氧微生物分解转化有机物而生成的一种可燃性气体。主要成份是:甲烷(占60—70％),二氧化碳(占30—40％),少量的一氧化碳、氮、硫化氢等微量气体。沼气贮粮就是在容器完全密封的情况下,利用沼气中甲烷和二氧化碳含量高、含氧量甚微及甲烷无毒、无菌、无污染的特点,调节贮粮环境中的气体成份,造成一定的缺氧状态,控制粮食和种子的呼吸强度,减弱新陈代谢功能,降低贮存过程中的基质消耗,使之形成休眠状态,以达到防止霉变、贮存粮
Biogas is not only a kind of biomass energy, but also a kind of environmental gas modulating agent, which can be used for storing food, storing seeds and preserving fruits and vegetables. Biogas storage grain, is a simple and easy, less investment, significant economic benefits of practical technology. First, the mechanism of action Biogas is an inflammable gas generated by the decomposition of anaerobic microorganisms into organic matter. The main components are: methane (60-70%), carbon dioxide (30-40%), a small amount of carbon monoxide, nitrogen, hydrogen sulfide and other trace gases. Biogas stored grain is the case of the container is completely sealed, the use of biogas methane and carbon dioxide in the high, low oxygen content and methane non-toxic, sterile, non-polluting features, regulating the grain storage environment gas composition, resulting in certain Of hypoxia, control the respiration intensity of grain and seed, weaken the metabolic function, reduce the matrix consumption during storage, so as to form a dormant state in order to achieve prevent mildew, storage of food
