Rice seedling raising substrate based on various agricultural wastes and preparation method of rice seedling raising substrate

The invention discloses a rice seedling raising substrate based on various agricultural wastes and a preparation method of the rice seedling raising substrate, and belongs to the technical field of rice seedling raising substrates. The various mixed agricultural wastes such as straw powder, mushroom dregs and cow dung are selected, and a propagation expanding microbial agent for treating a mixtureof livestock and poultry manure and mushroom bran is added for sufficient fermentation, so that the rice seedling raising substrate with the high nutrient content is prepared. The problems that as for a rice seedling raising substrate based on various agricultural wastes, the various agricultural wastes are difficult to ferment sufficiently, and nutritional ingredients are insufficient are solved, resource utilization of the agricultural wastes is achieved, and environmental protection is also facilitated. 本发明公开了一种基于多种农业废弃物的水稻育秧基质及其制备方法，属于水稻育秧基质技术领域。本发明选用秸秆粉、蘑菇菌渣和牛粪等多种混合农业废弃物，添加用于处理畜禽粪便和菌糠混合物的扩繁菌剂进行充分发酵，制得营养成分高的水稻育秧基
