Pleurotus edible fungus rapid proliferation nutrient solution and pretreatment method of cultivated species of nutrient solution

Abstract

The invention discloses a pleurotus edible fungus rapid proliferation nutrient solution, each 1,000 ml of hyphae rapid proliferation nutrient solution comprises 5 g of saccharose, 5 g of trehalose, 1 g of glucose, 0.05 g of chlorogenic acid, 0.05 g of VB2, 0.05 g of VB6 and the balance of water, and the PH is 7.0. Accordingly, the invention further discloses a pretreatment method of corresponding cultivated species. The proliferation nutrient solution added with different sugars, the vitamins and the antibacterial agent is used for pretreatment on cultivated specie mycelium, the fungus vigor is enhanced, the setting time of mycelium is shortened, the anti-bacterial capability of the mycelium is improved, and therefore, and the sundry fungus pollution rate is reduced while an open type inoculation method is ensured to be adopted. At the same time, a stapler breathable type sealing manner is adopted, oxygen supply during out-of fungus bag culture is enhanced, and the mycelial growth cycle is shortened. Rapid culture, high yield and harmlessness of the pleurotus edible fungus can be realized.

Description

technical field [0001] The invention belongs to the field of edible fungus cultivation, and in particular relates to a nutrient solution for rapid proliferation of edible fungi of the genus Pleurotus and a pretreatment method for the cultivated species thereof. Background technique [0002] The inoculation of edible fungus mushroom bags is an important technical link in the production of edible fungi. The inoculation speed and inoculation quality are related to the yield of mushroom bags, mycelium growth speed, quality and final biological conversion rate. At present, the commonly used mushroom bag inoculation methods mainly include ultra-clean workbench inoculation and manual inoculation box inoculation. Their shortcomings are: [0003] (1) The inoculation site needs to irradiate the air with ultraviolet light or fumigate with formaldehyde and phenol every day. While radiation treatment and chemical fumigation kill microorganisms in the air, they also cause a certain degre...

AI Technical Summary

Problems solved by technology

While radiation treatment and chemical fumigation kill microorganisms in the air, they also cause a certain degree of harm to the body of the vaccinators. At the same time, the investment cost of ultra-clean workbench is high, which is unaffordable for ordinary mushroom growers.

[0004] (2) Due to the limited working interface of the ultra-clean workbench and the inoculation box, the bacteria bag enters and exits the ultra-clean table and the inoculation box during the inoculation operation, and it takes a lot of time to open and seal the bacteria bag during inoculation, which reduces the inoculation speed

[0005] (3) When the cultivars whose surface is covered with bacterial species are placed on a new medium, the mycelium will be damaged to a certain extent due to the cutting of the bacterial block during inoculation, and an adaptation period of 5-7 days is required on the new medium. The recovery of growth not only prolongs the cultivation time of mycelium, but also provides opportunities for the infection of miscellaneous bacteria; at the same time, because the bag mouth is sealed by stuffing cotton, the air permeability is poor, resulting in slower growth of mycelium in the later stage
