Preparation method of rice seedling raising substrate taking coffee grounds as base material

The invention discloses a preparation method of a rice seedling raising substrate taking coffee grounds as a base material and the rice seedling raising substrate prepared by the preparation method. According to the method, the industrial waste coffee grounds are used as a main base material, nutrient substances and beneficial bacteria are added for fermentation to obtain a coffee grounds fermentation decomposed substance, earthworms are used as digestion organisms for biological digestion of the coffee grounds to obtain wormcast, and finally the obtained wormcast is used as a substrate for rice seedling raising. The method can effectively solve the problem of difficulty in biotransformation and utilization of the coffee grounds, and is simple and convenient in process operation, low in cost and high in generalization performance. 本发明公开了一种以咖啡渣为基料的水稻育秧基质制备方法及制备获得的水稻育秧基质。本发明以工业废弃物咖啡渣作为主要基料，通过添加营养物质及有益菌进行发酵，得到咖啡渣发酵腐熟物，并以蚯蚓作为消解生物进行咖啡渣的生物消解得到蚯蚓粪，最终以得到的蚯蚓粪作为基质用于水稻育秧。本发明可有效解决咖啡渣的生物转化利用较为困难问题，而且工艺操作简单方便，成本低廉，推广性较强。
