The invention discloses a soil covering matrix for improving the formation amount of Agaricus bisporus fruiting bodies and a preparation method thereof. The soil cover matrix is made up of weight parts, comprising: fermentation bacteria bran 65~75 parts and river clay particles 25~35 parts. The preparation method comprises the following steps: WMLE impurity removal, drying to moisture content is less than 15%, crushed into 0.5~1.0cm particles, and then sprinkled with lime water, the water content was adjusted to 55~65%, long fermentation 20~30 days, and until the pH value is 7.5~8.0. The river mud drain water, drying to a moisture rate less than 15%, broken into 0.5~1.0cm particles, to sun 1~2d, removing impurities. According to the formula proportion, the fermented mushroom bran and the river soil granule are mixed, and then quenched and quenched to pH, the water content is 7.5~8.0, and the water content is 18~20%. The soil cover of the invention has proper nutrient content, good water retention and release characteristics, and can obviously increase the amount of formation of fruiting bodies of Agaricus bisporus and the fruiting degree of fruiting bodies, and shorten the time of fruiting. The preparation method can realize multi-stage recycling of the waste medium and promote the development of the circular economy of edible fungi.
【技术实现步骤摘要】
一种提高双孢蘑菇子实体形成量的覆土基质及其制备方法
本专利技术属于食用菌栽培
,具体涉及一种提高双孢蘑菇子实体形成量的覆土基质及其制备方法。
技术介绍
双孢蘑菇(Agaricusbisporus(Large)Sing)菇体色质白嫩,味道鲜美,富含甘露醇、有机碱、菌糖等营养物质,是典型的低脂肪、低能量、高蛋白的菌类保健食品,还具有较好的药用功能。属于目前世界上栽培地域较广、生产规模较大、产量较多、消费量较大的人工栽培食用菌之一。在双孢蘑菇栽培过程中,菌丝生长到一定阶段,必须覆土才能诱导形成子实体。覆土基质的组成及其理化性质的差异,是影响双胞蘑菇产质量及出菇整齐度和出菇时间的重要因素。因此,理想的覆土基质必须具备独特的理化性质及微生物组成,以改善其养分结构和对水分的持留及释放特性。菌糠是食用菌生产后废弃的菇体培养基,食用菌栽培产生的菌糠数量大,菌糠处理一直是食用菌产业的难点。菌糠虽在食用菌栽培阶段被利用了大部分的营养物质,但仍含有丰富的有机物质、氮素以及各类微量元素。此外,菌糠还含有丰富的微生物生态群落,其微生物群落与双孢蘑菇的菌丝存在营养共生关系。基于此,本专 ...
