Description

Technical Field

[0001] The utility model belongs to the technical field of edible fungus cultivation equipment, and in particular relates to an edible fungus cultivation cover. Background Art

[0002] Dictyophora rubrovolvata belongs to the genus Dictyophora. It is a rare edible fungus. Its fruiting body is white, with a skirt and a stipe. It has a beautiful appearance and a fragrant smell. It is known as the "Snow Skirt Fairy" and the "Queen of Fungi". Dictyophora rubrovolvata is a unique variety of Dictyophora in Guizhou. Its mycelium growth temperature is 4-28℃, and the fruiting body nucleus development temperature range is 15-25℃. The mycelium of Dictyophora rubrovolvata grows very slowly. The traditional cultivation cycle is long. It is only suitable for growth in some areas of Guizhou, and it is difficult to expand its scale. With the technical breakthroughs of cultivating Dictyophora rubrovolvata with mushroom sticks and liquid strains of Dictyophora rubrovolvata, the planting cycle of Dictyophora rubrovolvata has been shortened from 12 months to 4-6 months, expanding the adaptability of Dictyophora rubrovolvata. The mushroom production model can adopt forest cultivation, shelf cultivation, basket cultivation, factory cultivation, etc., which can be promoted throughout the country.

[0003] With the development of the scale of the red-stemmed bamboo fungus industry, the quality control of the red-stemmed bamboo fungus bags has become more stringent. In the current red-stemmed bamboo fungus cultivation process, it is found that the culture medium is prone to aging and softening in places with sufficient air permeability at the bag mouth, and is prone to produce green mold at the bottle mouth. Therefore, it is particularly important to adjust the air intake at the bag mouth to improve the respiration of the red-stemmed bamboo fungus, which can reduce the softening of the top of the red-stemmed bamboo fungus and the green mold at the bottle mouth.

[0004] The Chinese invention patent with publication number CN111328638A discloses an edible fungus cultivation bottle and its bottle cap. The air inside and outside the edible fungus cultivation bottle is exchanged through the vents formed on the upper cover and the lower cover. The ventilation structure of the bottle cap is an upper ventilation method, which ensures the stability of the water content of the culture medium during the sterilization process. The good air permeability can also effectively promote nutrient conversion, shorten the culture time, and improve the yield and quality of edible fungi. The Chinese utility model patent with publication number CN212260015U discloses a breathable cover for an edible fungus cultivation bottle. The adjusting disk is driven to rotate by adjusting the rotary rod, and the adjusting disk is used in conjunction with the breathable disk to make the number of air holes adjustable, thereby adjusting the air permeability of the entire cultivation bottle. The two bottle caps mentioned above have complex structures and high production costs. Utility Model Content

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, but it should not be understood that the scope of the subject matter described in the present invention is limited to the following embodiments. Without departing from the above-mentioned technical ideas of the present invention, various modifications, substitutions and changes made according to the common technical knowledge and customary means in the field are included in the scope of the present invention.

[0021] Reference Figure 1-Figure 3 A mushroom culture cover includes an end cover and a base 5. The end cover is composed of two covers, namely an inner cover 1 and an outer cover 2. The inner cover 1 is set inside the outer cover 2. The inner cover 1 and the outer cover 2 can be combined and rotated, and there are two air holes on each side. The first air hole 3 opened on the inner cover 1 is 1 / 2-2 / 3 of the area of ​​the second air hole 4 opened on the outer cover 2. The air intake of the end cover is adjusted by rotating the outer cover 2 to adjust the overlap between the first air hole 3 and the second air hole 4, so as to achieve the function of controlling the air intake of the culture cover.

[0022] The base 5 is combined with the outer cover 2 through a thread, and two layers of breathable non-woven fabric are covered between the base 5 and the outer cover 2 to filter air and block the spread of bacteria. The culture cover is made of high temperature resistant polypropylene material.

[0023] The height of the inner cover 1 is equal to the height of the outer cover 2, the outer wall thread of the inner cover 1 cooperates with the inner wall thread of the outer cover 2, and the outer cover 2 can rotate left and right along the outer wall of the inner cover 1. There are two first air holes 3 on the inner cover 1 and two second air holes 4 on the outer cover 2, which are symmetrical to each other. The base 5 is a hollow structure. The number of layers of breathable non-woven fabric provided between the base 5 and the outer cover 2 is determined according to the culture requirements. The radii of the inner cover 1, the base 5, and the outer cover 2 increase in sequence.

[0024] Embodiment: During the growth process of red-tube bamboo fungus, its growth is very slow, and its mycelium biomass produces less heat than other edible fungi, so that red-tube bamboo fungus has a very strong ability to decompose sawdust. In order to reduce the breeding of bottle mouth green mold and aging and softening of red-tube bamboo fungus during its growth process, the respiration of red-tube bamboo fungus is reduced by adjusting its air intake in the later stage of its growth to solve the above problem.

[0025] The culture cover of the device is installed at the bag mouth of the bag containing the red-tipped bamboo fungus, the rest of the bag is kept sealed, the outer cover 2 is rotated, the size of the air holes is controlled, the air inlet ratio is adjusted to the required ratio, and the ambient temperature of the culture room is lowered, so that the air intake of the red-tipped bamboo fungus can be controlled, the chance of the entry of miscellaneous bacteria can be reduced, and the occurrence of green mold at the bottle mouth of the red-tipped bamboo fungus can be reduced. At the same time, the respiration and biological activity of the red-tipped bamboo fungus are reduced, and the decomposition ability of the red-tipped bamboo fungus hyphae on sawdust is reduced, thereby slowing down the aging and softening of the red-tipped bamboo fungus.

[0026] The above is a detailed introduction to a mushroom culture cover provided by the utility model. This article uses specific examples to illustrate the structure and working principle of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
