Method for producing morchella cultivars on large scale

Abstract

The invention discloses a method for producing morchella cultivars on a large scale. The method comprises the following steps of taking a raw material mixed by mineral solid particles and organic materials as a culture medium of stock seeds; and mechanically and automatically bagging the cultivars for production, performing fully sealing, sterilizing and cooling, punching 1-3 holes in each fungusbag for inoculation on an aseptic environment inoculation table on an assembly line, each fungus bag being sleeved with an aseptic bagging bag, and loosening the opening for culture. The morchella cultivars are produced on a large scale by the method, more than 20,000 bags can be bagged by one bagging machine every day, the manual inoculation efficiency is 2,000-2,500 bags per hour (8 hours), thetime for mycelia to grow all over the fungus bags is 7-10 days, and the contamination rate of strains is lower than 0.1 percent. According to the method, the production efficiency can be greatly improved, the morchella cultivars can be produced on a large scale rapidly and efficiently with low contamination, the cost of each bag is reduced by 0.15-0.20 yuan, and the huge demand on the morchella cultivars in the morchella cultivation industry can be met.

Description

technical field [0001] The invention relates to the technical field of production of edible and medicinal fungus strains, in particular to a method for large-scale production of hickory chick cultivars. Background technique [0002] Morchella refers to the general designation of all species of the genus Morchellaceae (Morchella) of the Fungi Ascomycota, Ascomycota, Pezizomycotina, Pezizomycetes, Pezizales, Morchellaceae, which has more than 70 systematics species. This genus is divided into black group, yellow group and red group, etc. Most of the species cannot be artificially cultivated for fruiting bodies, and only a small number of species in the black and red groups can be commercially cultivated. At present, the species that can artificially cultivate fruiting bodies at home and abroad include: Morchella sextelata, Morchella importuna, Morchella eximia, Morchella angusticeps, Morchella rufobrunnea , Morchella exuberans, Morchella oweri, Mel-13, Mel-21, etc. The comm...

AI Technical Summary

Problems solved by technology

This kind of technical operation is very cumbersome, and the bagging production speed is very slow

[0006] Second, the risk of pollution is high

The morel cultivars are produced by this method, and the strain bag and the cap are all in a bare state during the cultivation process, and are easily affected by the external environment

Because there are fine powders of compost left on the surface of the bacteria bag, the surface of the cover, the filter membrane inside the cover, the inside of the bag, and between the multi-layer films of the bag, during the high temperature and high humidity seasons of October and November Carry out cultivation, be easy to be impregnated by miscellaneous bacteria, as Neurospora Neurospora, Penicillium Penicillium, Trichoderma Trichoderma, Aspergillus niger, Rhizopus Rhizopus, Mucor Mucor, Fusarium Fusarium etc.; Such method produces hickory chick cultivation According to the analysis of a large number of on-site statistical data, it is found that among more than 60% of the cultivated morel strains produced by the morel cultivated strain manufacturers, 20% or even more than 50% of the more than 50% of them have visible appearance pollution; Even if the polluted strains cannot be seen in appearance, there is also a large amount of hidden pollution. When the morel cultivated strains are sown in the field, a large amount of field pollution will also occur. The survey of more than 10,000 mu shows that 90% All the above cultivated fields will be found to have mold pollution in different ratios, the contaminated area accounts for 10%-90% of the field area, and the proportion of the field without miscellaneous fungus pollution on the surface of the cultivated field is very small

Such hickory chick cultivation strains cannot meet the technical requirements for high-yield cultivation, often resulting in low yields for a large number of cultivators, poor economic benefits, and failure to obtain ideal commercial benefits.

[0007] Third, there is a risk of burning bacteria

During the cultivation process of bacteria with a cover, the bacteria bags are placed in parallel in the plastic basket, squeezed and stacked with each other, the bacteria bags are in close contact, the heat dissipation is poor, and the heat is accumulated, resulting in high-temperature burning of the bacteria, and the production of the bacteria cannot be used.

[0008] Fourth, it is difficult for mycelium to overgrow bacteria bags

Another problem with cultivating morel strains with a covered fungus bag is that the mycelium grows faster in the early stage, and the front 2 / 3-3 / 4 of the fungus bag can be full in 15-20 days, and the rest of the back 1 / 5-1 / 4 of it will take 10-20 days to overgrow, even unable to overgrow mycelium

The reason is that the compost is tight and not ventilated, the bacteria bags are squeezed against each other, and the water content of the culture material at the bottom of the fungus bag is high, so the mycelium cannot continue to grow rapidly, and it is necessary to perforate each fungus bag , the mycelium can grow fully

Drilling operations require a lot of labor and at the same time bring the risk of bacterial contamination

[0009] Fifth, the strains are prone to aging

[0010] Sixth, the training time is long

[0017] The above patent applications do not involve the technical content of the solid particle medium of the original species and the cultivation bag of the cultivated species for inoculation and bagging.
