Preparation method for substrate for planting edible fungus

Abstract

The invention discloses a preparation method for a substrate for planting edible fungus. The preparation method is characterized by comprising the following steps: (1), treating walnut shells, crushing the walnut shells into particles with diameter less than 10mm, soaking the walnut shells in plant ash water for 24-48 hours, and treating for later use, wherein weight of the plant ash water is 2-6 times the weight of the walnut shells; (2), treating mulberry branches and roasted tobacco stems, and crushing pine sawdust into particles less than 10 mm, respectively crushing the mulberry branches, the roasted tobacco stems as well as the pine particle tobacco stems and pine sawdust into particles with diameter less than 15mm to carry out terpene removal and ungrease treatment for later use; (3), mixing 30-60 parts (in parts by weight) of the walnut shells, 10-20 parts of the mulberry branches, 10-20 parts o the pine sawdust and 10-20 parts of bran or rice husk, adding 0.5-1 part of glucose and 1 part of gypsum for mixing. The method disclosed by the invention can sufficiently utilize the walnut shells which are normal and cheap raw materials in Yunnan to cultivate the edible fungus in an environment-friendly manner.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation, in particular to a method for preparing a substrate for cultivating edible fungi. Background technique [0002] Yunnan is the largest major walnut producing area in China. Walnuts are planted all over the territory of Yunnan, and the resources of by-products of the walnut industry are abundant. Yunnan Province produces more than 600,000 tons of walnuts annually, and the reserves of walnut shells, a by-product of walnuts, are more than 300,000 tons. Traditionally used for a small amount of processing of water purification materials, activated carbon is mostly used as fire fuel. In addition, mulberry trees are planted in most parts of Yunnan, and the branches of the mulberry trees are pruned every year. Some of the mulberry branches are used for cooking, and some are used for papermaking. Peach shells and mulberry branches are rich in cellulose, hemicellulose and lignin. These macromo...

Problems solved by technology

We found that the method of soaking walnut shells in water to reduce tannins has many defects. First, it takes a long time. Secondly, it will destroy the beneficial ingredients in the walnut shells to edible fungi, reduce the biotransformation rate, and cause the output of edible fungi to decrease and prolong the production of edible fungi. fruiting time
