Culture medium, fruiting bag and high-yield culture technique of Pleurotus nebrodensis

Abstract

The invention discloses a culture medium, a fruiting bag and a high-yield culture technique of Pleurotus nebrodensis. The culture medium of the Pleurotus nebrodensis is prepared by mixing main materials and auxiliary materials, wherein the main materials consist of cotton bark, wheat bran and nutritive grains, and the auxiliary materials consist of gypsum, farm-oriented monopotassium phosphate and lime. The weight of the culture medium in each fruiting bag is 200-285g. According to the invention, by a reasonable adjustment of components and a proportion of the culture medium, the conversion utilization rate of the culture medium is improved remarkably, the technical problem that the culture medium with rich nutrients is likely to bepolluted is well solved, and a common prejudice that the culture medium with rich nutrients is likely to be polluted is overcome.

Description

technical field [0001] The invention relates to the cultivation technology of edible fungus, in particular to the cultivation technology of short-handled palm-type Bailing mushroom. Background technique [0002] Bailing mushroom is a rare edible fungus with high edible and medicinal value. It has superior nutrition, magical medicinal effect and top quality. , Different growth and development stages have different requirements for light, carbon dioxide concentration, oxygen, humidity, and temperature, so growth requires unique environments and conditions. The deficiency that the cultivation technique of existing Bailing mushroom exists is: [0003] 1. The existing cultivation substrate has low nutrient content, and too much material is loaded in each bag (generally 400-600 grams per bag), resulting in low utilization rate of cultivation substrate, low biotransformation rate of Bailing mushroom, short-handled palm type The biotransformation rate of Bailing mushroom is genera...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing cultivation substrate has low nutrient content, and too much material is loaded in each bag (generally 400-600 grams per bag), resulting in low utilization rate of cultivation substrate, low biotransformation rate of Bailing mushroom, short-handled palm type The biotransformation rate of Bailing mushroom is generally about 40%, which causes a waste of manpower, raw materials, space, and funds, and the economic benefits of cultivation enterprises and cultivation households are generally low

[0004] 2. In the germination stage, influenced by the traditional concept, the temperature is relatively high, generally at 22-26°C, which makes the hyphae vulnerable to miscellaneous bacteria;

[0005] 3. The sterilization time of the bacteria bag is relatively short. When the temperature between the bags reaches 100°C, it only lasts for 12 to 16 hours, which cannot completely sterilize the bacteria bag and decompose the cultivation medium better, and cannot better facilitate the absorption of mycelia.

[0006] 4. In the fruiting stage, the mistakenly increased the light intensity to cultivate Bailing mushroom, which wasted energy and increased investment in the cultivation of temperature-adjusted warehouses; increased workload when cultivated in houses or greenhouses

[0007] 5. In the mushroom bud induction management stage, the traditional maximum concentration of carbon dioxide is controlled within 0.1%, and in the fruiting body growth and development stage, the traditional maximum concentration of carbon dioxide is controlled within 0.12%, which increases technical difficulty and investment

[0008] 6. When cultivated in cold storage, the fruiting is irregular and there are many deformed mushrooms

[0009] 7. In the late stage of fruit body growth and development in traditional cultivation methods, that is, when the size of a table tennis ball is large, the light intensity is greater than 600 lux, which increases material resources and technical difficulties

[0011] 9. Some are bagged with fermented materials, and the nutritional loss is too large due to improper fermentation

[0012] Due to the above reasons, the yield of Bailing mushroom is low, the cost is high, the benefit is low, the cultivation process is difficult to manage, and the cultivation process cannot be popularized and used in a large area.
