Biomass charcoal base fertilizer prepared from gramineous plant waste and preparation method thereof

The invention belongs to the technical field of fertilizer preparation, and particularly relates to a biomass charcoal base fertilizer prepared from gramineous plant waste and a preparation method thereof. Biomass charcoal is obtained by pyrolysis and carbonization of agricultural wastes, organic matters and NPK elements are mixed and ammoniated to prepare the organic fertilizer, resources can beutilized to the maximum extent, and fermentation is performed by adopting an active fermentation microbial inoculum so that the obtained biomass charcoal base fertilizer has the fixed carbon content of 47.1%, the organic matter content of 50% or above and the fertilizer utilization rate of 78.4% and the fertilizer is easily absorbed and utilized by crops. 本发明属于肥料制备技术领域，具体涉及一种用禾本科植物废弃物制备的生物质炭基肥及其制备方法；通过对农业废弃物进行热解炭化得到生物质炭、将有机物和N-P-K元素混合氨化，制成有机肥，可对资源进行最大限度的利用，并采用提活的发酵菌剂进行发酵，得到的生物质炭基肥固定碳含量达到47.1％，有机质含量在50％以上，肥料利用率78.4％，更易被作物吸收利用。
