DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for modifying a mushroom cultivated bacterial bed into a useful substance and a soil activator obtained by the method.

[0002]

2. Description of the Related Art In recent years, as a method for cultivating edible mushrooms such as shiitake mushrooms, fungal bed cultivation has been performed instead of log cultivation using raw wood. In this fungal bed cultivation, broadleaf wood such as Mizunara, Japanese oak and Kunugi is naturally dried for about 6 months, and then processed into wood lakes such as sawdust and wood chips, and rice bran as a nutrient source. Stuffed in a plastic bag, and then sterilized under pressure. After adding this strain in a sterile room, cultivation and aging for 3 to 6 months under a constant temperature condition to solidify it into an artificial ladder tree. From to the production farmers. Producing farmers arrange a large number of the artificial hoda trees on shelves provided in a house where temperature and humidity conditions are maintained, and harvest and ship the mushroom fruit bodies to the market each time they occur. With such an artificial hoda tree,
The fruiting body can be shipped around 4 weeks after being put in the house, but since it is continuously generated for 6 to 7 months, many artificial mushrooms can be harvested from one artificial hoda tree and regardless of the season It can be produced all year round, and the yield is constant without being affected by the weather, etc., so it can be planned production. In addition, the quality, color and shape are constant and good quality mushrooms can be obtained, so the management of the production farmers is stable. Has been evaluated as an excellent cultivation method to do.

[0003]

However, since the effective production period of the artificial jolt tree in the house is 6 to 7 months, when the fruiting body is not generated after this period, a new artificial jolt tree is produced. They are exchanged for continuous production, but the used artificial honda trees still have about half the volume compared to the new artificial honda trees, so leave them in a pile and leave them alone or spray them to the fields. Used as fertilizer. However, there are several tens to hundreds of houses in the above-mentioned production farmhouses in one district, and since 20,000 or more artificial ladder trees are discarded per house per year, a large place for artificial ladder trees to be piled up is secured. In addition, there is a problem that the environment such as the surrounding scenery is deteriorated. Furthermore, when applied to the fields and used as fertilizer, the rate of oxidative decomposition of the raw wood lignin contained in the artificial hod tree is slow, so it can only be a slow-acting fertilizer. There is a problem that occurs.

[0004] The present invention has been made in view of the above circumstances, the means is that the mushroom cultivated bacteria bed,
