Problems solved by technology

On the other hand, the mycelium of Dictyophora edulis grows slowly, with an average growth rate of 1mm / d. It takes one month for the bagged Dictyophora strain to grow to the mouth of the bag after inoculation. The longer the culture time, the traditional production method, it takes 6-8 months for mycelia to fill the bag, resulting in higher culture infection
Through long-term mass production practices, observations and experiments, it has been determined that the main reason for the infection of Neurospora fungus in Dictyophora edulis in bags is that pests (mites, insects, etc.) enter the culture container through the gap between the lid and the bag wall and carry the bacteria. In addition, the time required for strain cultivation is longer, and the probability of infection increases significantly, which will greatly affect the quality of strains. In severe cases, the infection rate of Neurospora can reach more than 80%, and even the cultivated species are completely wiped out.

Abstract

The invention provides a production method for reducing infection of cultivated species of dictyophrarubrovolvata by streptomyces spp. and belongs to the technical field of edible fungus cultivation.The production method includes: putting a culture medium of the cultivated species in a polyvinyl bag, inserting an inoculating rod vertically into the culture medium of the cultivated species, and sealing the bag mouth prior to performing sterilization to obtain a sterilized cultivated-species bag, wherein the culture medium of the cultivated species includes sawdust, wheat gluten, corn flour, soybean flour, gypsum, sugar, potassium dihydrogen phosphate, magnesium sulfate and water; opening the bag mouth of the cultivated-species bag in aseptic environment, taking out the inoculating rod toreserve a hole for the cultivated species to pass through, inoculating original species of dictyophrarubrovolvata in the hole, sealing the bag mouth of the cultivated-species bag with strains, and performing culture after sealing. The culture of the dictyophrarubrovolvata is shortened from 6 months to 60 days, the damage time and probability of pests are reduced, and the occurrence of the streptomyces spp. is significantly reduced.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a production method for reducing Neurospora infection of Dictyophora edulis cultivars. Background technique [0002] Dictyophra rubrovolvata (Dictyophra rubrovolvata), native to the Wumeng mountainous area in northwestern Guizhou, is a large fungus and is a species of edible bamboo fungus, belonging to the genus Dictyophra rubrovolvata, also known as bamboo fungus and bamboo ginseng. is a hidden flower parasitic on the roots of dry bamboo fungus . snow white cylindrical Stipe (hollow, spongy), white reticulated fungus skirt (spongy), earth gray cap (cap with wrinkled, cap with a large number of spores attached), pink (white in dark conditions, white in low light conditions) Pink scale-like small lobes, pink under low light, purple to brown under strong light) rough egg-shaped Tray , the white mesh skirt stretches downward from the cap at the to...
