EM bacteria (Effective Microorganisms) Is composed of about 80 kinds of microorganisms, and EM bacteria are successfully researched by professor bijia phf of Youkai university of Japan in 1982 and are put into the market in 80 years. The EM is a microbial preparation which is compounded by 10 microorganisms which are more than 80 and mainly comprise photosynthetic bacteria, lactic acid bacteria, saccharomycetes and actinomycetes. The action mechanism is to form competition of the EM bacteria and the pathogenic microorganisms for nutrition, and the EM bacteria are easy to survive and reproduce in the soil, so the EM bacteria can quickly and stably occupy the ecological status in the soil, and form a dominant community of beneficial microorganisms, thereby controlling the reproduction of the pathogenic microorganisms and the attack on crops. Is the development direction of ecological agriculture, and is more beneficial to the sustainable development of agriculture. In the late 80 s and early 90 s, EM bacteria have been widely applied to the fields of agriculture, cultivation, planting, environmental protection and the like by Japan, Thailand, Brazil, America, Indonesia, Srilanca and the like, and obvious economic benefit and ecological benefit are obtained.
