Embodiment 1

[0012] Embodiment 1. walnut shell is pulverized into diameter size in 1mm particle, soaks walnut shell with water 24 hours at normal temperature to reduce the content of tannin, and the mass ratio of walnut shell and water is 1: 2; Walnut shell, sawdust, wheat bran The mass ratio is 60%, 23%, 15%, add 0.5%-1% glucose and 1% gypsum, and mix evenly to make compost; after high-temperature sterilization in the usual way at 100-120°C, let cool to room temperature, Inoculate strains, for example, Pleurotus 99 provided by Kunming Edible Fungi Research Institute. During the cultivation process, the development and fruiting of mushrooms are consistent with the usual cultivation methods of edible fungi.

Embodiment 2

[0013] Embodiment 2. walnut shells are pulverized into particles with a diameter of 3 mm, soaked walnut shells with water for 28 hours at normal temperature to reduce the content of tannin, the mass ratio of walnut shells and water is 1: 4; walnut shells, sawdust, wheat bran The mass ratio is 50%, 38%, 10%, add 0.5%-1% glucose and 1% gypsum, and mix evenly to make compost; after high-temperature sterilization in the usual way at 100-120°C, let cool to room temperature, Inoculate strains, for example, Pleurotus 99 provided by Kunming Edible Fungi Research Institute. During the cultivation process, the development and fruiting of mushrooms are consistent with the usual cultivation methods of edible fungi.

Embodiment 3

[0014] Embodiment 3. walnut shell is pulverized into diameter size in 5mm particle, soaks walnut shell with water at normal temperature 28 hours to reduce the content of tannin, the mass ratio of walnut shell and water is 1: 4; Walnut shell, sawdust, wheat bran The mass ratio is 60%, 23%, 15%, add 0.5%-1% glucose and 1% gypsum, and mix evenly to make compost; after high-temperature sterilization in the usual way at 100-120°C, let cool to room temperature, Inoculate strains, for example, Pleurotus 99 provided by Kunming Edible Fungi Research Institute.

Abstract

This invention relates to a method of using walnut shell as matrix for mushroom cultivation. Walnut shells contain vegetable tannin that inhibit reproduction of true fungus, so ignore possibility of it as mushroom medium. This method includes medium heat sterilization, vaccination. Medium preparation methods are : (1) smash the walnut shell, in size of diameter below 1 mm to 10mm, at room temperature water immersion walnut shells 24-72 hours to reduce tannin content, walnut shells and water quality ratio (1 : 2) - (1:8); (2) take walnut shell, wood and wheat bran as compost, quality ration of: the walnut shell 50% -70%, 10% -38% sawdust, wheat bran 18% -10%, by adding glucose 0.5% -1% and Gypsum 1%. This invention use abandoned walnut shells as materials, not rely on higher-value raw materials, will brought facilitating role for walnut producing farmers, walnut processing enterprises and mushroom cultivation.

Description

technical field [0001] The invention relates to a method for cultivating edible fungi using walnut shells as a substrate. Background technique [0002] Utilizing the waste produced by local crop processing as raw material for the production of edible fungus culture medium according to local conditions can promote the economic development of mountainous areas, making it a technical field that biological scientists pay attention to. production method". There is a water-soluble substance contained in walnut shell, and the aqueous solution is yellowish brown. Many properties show that the substance may be plant tannins, also known as plant polyphenols. Vegetable tannin is an important chemical product, which plays an important role in the manufacture of pharmaceuticals and leather tanning. It has a certain inhibitory effect on fungi. Due to this characteristic of walnut shells, people have ignored the possibility of using walnut shells as a medium for cultivating edible fungi. ...
