Earlier-stage treatment method adopting cotton straw to prepare pleurotus edible mushroom cultivation raw material

Abstract

The invention discloses an earlier-stage treatment method adopting cotton straw to prepare pleurotus edible mushroom cultivation raw material. The method comprises the step of fermenting the raw material including cotton and firewood powder dust to obtain an edible mushroom cultivation substrate. The core of the method is that fermentation treatment is conducted after the cotton straw is smashed to improve the physical and chemical properties of the cotton straw, so that the cotton straw becomes a main cultivation material suitable for edible mushroom cultivation. The species of mushroom suitable for the obtained cultivation substrate include oyster mushroom, pleurotus eryngii, pleurotus nebrodensis, pleurotus geesteranus, pleurotus cornucopiae and other pleurotus edible mushrooms.

Description

technical field

[0001] The invention relates to a pretreatment method for preparing raw materials for cultivating edible fungi of the genus Pleurotus with cotton stalks (cotton firewood). Background technique

[0002] The early production of edible fungi in our country was produced by segmented wood, and the diameter of mushroom wood was required to be more than 10cm. However, after the industry has developed to a certain scale, improper control and management can easily lead to deforestation and limit the development of edible fungus production.

[0003] In the 1950s, my country first succeeded in using sawdust as a substitute for edible fungus cultivation. Later, cottonseed hulls were used as the main material, and wheat bran, rice bran and other auxiliary materials were added to successfully cultivate edible fungi. The expansion of edible fungi cultivation raw materials has greatly promoted the development of edible fungi production in my country, especially since the re...

Embodiment 1

[0040] The preparation and application of embodiment 1, cultivation substrate 1

[0041] 1. Cultivation Substrate I

[0042] Raw material formula: 90 parts by mass of cottonwood, 7 parts by mass of wheat bran, 1 part by mass of gypsum powder and 2 parts by mass of lime.

[0043] 1. Mixing and pre-wetting of raw materials

[0044] After the cotton firewood is crushed (the aperture of the grinder screen is 15mm), various raw materials are mixed evenly according to the formula, and water is added to fully pre-wet to obtain compost. The moisture content of the compost is 70% (mass percentage).

[0045] 2. Stacking fermentation

[0046] The compost obtained in step 1 is fermented by stacking, and the temperature of the environment is above 10°C.

[0047] (1) Building piles

[0048] The height of the pile is 1.5m, the width is 2m, and the length is more than 4m.

[0049] (2) turn over

[0050] Keep the internal temperature above 60°C for 6 hours and then turn over the compost....
