Method for preparing fruiting fungus bag for oyster mushroom with cornstalk as principal raw material

Abstract

The invention belongs to the novel technical field of cultivation of edible mushrooms, and particularly relates to a method for preparing a fruiting fungus bag for oyster mushroom with a cornstalk as a principal raw material. The method comprises the steps as follows: the pure elongated cornstalk which is not required to be smashed is taken as the principal raw material and cut into segments of 25-30 cm, and the segments are soaked in lime water and fermented; and corncobs, corn husks, corn flour and quick lime are taken as auxiliary materials, the fermented cornstalk segments and the auxiliary materials are bagged, and the fruiting fungus bag for production is prepared through sterilization, inoculation and fungus cultivation. According to the method, the used principal raw material, namely, the cornstalk is not required to be smashed or ground during application and is used integrally, investment for special facilities, and labor and the like which are required when the cornstalk is smashed or ground at ordinary times is reduced; besides, the speed of the hypha is slow when the hypha is transformed into the cornstalk, the transformation period is long, the biotransformation rate is high, and the produced economic benefits are remarkable.

Description

technical field [0001] The invention belongs to the field of new edible fungus cultivation technology, and in particular relates to a method for preparing oyster mushroom fruiting bag with corn stalks as the main raw material. technical background [0002] Corn is one of the main crops in my country, and it is cultivated all over the country. Corn stalks after harvesting corn have been mostly burned on site as waste, causing environmental pollution and waste of resources. At the turn of autumn and winter, corn stalk burning pollutes the air and often becomes the target of public criticism. The pollution caused by "straw burning" has plagued the pollution of the national air environment. [0003] Relevant test results show that corn stalks contain more than 30% carbohydrates, 2%-4% protein and 0.5%-1% fat, and the net energy gain of 2kg corn stalks is equivalent to 1kg corn kernels. [0004] Cultivating Pleurotus ostreatus with resource-rich corn stalks as raw materials is...

Problems solved by technology

This technical solution needs to use a stone roller to crush the corn stalks. This procedure is also time-consuming and labor-intensive, and the work efficiency is very low.
