Method for preparing lentinus edodes cultivation matrix from corncobs and broad-leaved tree sawdust

Abstract

The invention discloses a method for preparing lentinus edodes cultivation matrix from corncobs and broad-leaved tree sawdust. The lentinus edodes cultivation matrix is prepared from, by mass, 47% of corncob powder, 40% of the broad-leaved tree sawdust, 10% of wheat bran or rice bran, 1% of bean flour and 1% of gypsum powder, and a plant growth regulator accounting for 0.05% of the total amount of the matrix is added. The broad-leaved tree sawdust comprises sawdust of poplars, willows, elms, oaks and birches. By replacement of broad-leaved hard tree sawdust with the corncobs and the broad-leaved tree sawdust including sawdust of poplars, willows, elms, oaks and birches for lentinus edodes cultivation, different cultivation matrixes are adopted while the plant growth regulator is added, and substances, unsuitable for the lentinus edodes cultivation matrix in the raw materials are converted, degraded or removed by means of biological fermentation, so that replacement of the broad-leaved hard tree sawdust for lentinus edodes cultivation is realized.

Description

technical field [0001] The invention belongs to the technical field of edible fungi in microbial science, and in particular relates to a method for preparing a substrate for cultivating shiitake mushrooms by using corn cobs and broad-leaved miscellaneous sawdust. Background technique [0002] Lentinus edodes is a wood rot type edible fungus. In the past, eucalyptus was mainly used for wood segment cultivation in the cultivation of lentinus edodes. Due to the shortage of forest resources, shiitake mushrooms are cultivated with substitute materials. yield and quality. Many articles have been published in various academic journals at home and abroad about using cottonseed hulls, straw, corncobs, bagasse, mulberry branches or fruit branches to cultivate shiitake mushrooms. These cultivation experiments are mainly used for research, without large-scale production, and without using Reports on large-scale cultivation of shiitake mushrooms such as cottonseed hulls, rice straw, cor...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a preparation method for cultivating shiitake mushroom substrates by using corncobs and broad-leaved miscellaneous wood chips, aiming at solving the problem of high transportation cost of existing raw materials for cultivating shiitake mushrooms, and using cottonseed hulls, bean stalks, rice straw and corncobs for cultivation The ratio of the mushroom formula is unreasonable, the compost is not effectively treated, the output of the mushroom is low, and the quality declines
