Agaricus bisporus spawn-making technology

Abstract

A process for producing Agaricus bisporus strains, comprising the following steps: mixing wheat grains or millet grains that are free from mildew, impurity, insect disease, broken, and ungerminated, and then put them into lime water at 20°C in a rotating Soak in the state for 20 hours; after treatment, mix in auxiliary materials; put it into the container and use a vacuum system to vacuumize it 1-4 times, and sterilize it at a constant temperature for 2.5 hours; after the sterilization, the sterilization pressure drops to 0 When the bag temperature drops below 28°C, carry out aseptic inoculation, insert solid bacteria or liquid bacteria; after mixing, pour the mixed bacteria into the bag through the discharge port Put it in the strain bag and seal it. The advantages and beneficial effects of the present invention: high-temperature sterilization makes the inoculation infection rate low, and is applicable to the production of edible fungi, especially grass-rot fungus strains, breaking through the bottleneck in the production of grass-rot fungus strains in the prior art.

Description

technical field [0001] The invention belongs to the cultivation technology of edible fungi, and in particular relates to a seed production process of Agaricus bisporus. Background technique [0002] In recent years, the demand for food consumption is shifting from consumption of fish and meat to vegetables, and paying attention to healthy diet and hygiene and safety have been considered as the primary prerequisites. The edible fungus represented by "Su Zhong Wang" Agaricus bisporus is very popular in the market, and it is famous for its freshness, tenderness, fat, fragrance, and pure natural green food. Edible fungus was introduced and cultivated in my country in the 1920s. At present, it has been cultivated in large areas in the south of the Yangtze River, and the cultivation technology is becoming more and more mature. my country has surpassed the United States to become the world's first edible mushroom planting and exporting country, and the market consumption demand is...

Problems solved by technology

Although the cost of factory-cultivated products is high and the main consumers are high-end consumer groups, due to the small production volume, most varieties have a large market space, and with the development of the economy and the improvement of the living standards of the public, the consumer groups will gradually Expand to middle and low-end consumers

[0003] At present, the edible fungus seed production technology is not perfect, and the infection mortality rate is high, which directly affects the development of grass rot fungus cultivation technology, and has become a bottleneck for the large-scale cultivation of grass rot fungi and the improvement of economic benefits of cultivation.
