Culture medium for selenium-rich organic edible fungi and culture method thereof

Abstract

The invention provides a culture medium for selenium-rich organic edible fungi, which is mainly prepared from the following raw materials in parts by mass: 60-90 parts of culture main material, 10-25 parts of carbon organic fertilizer, 1-5 parts of selenium-rich nutrient element, 1-6 parts of root irrigation culture agent, 0.2-0.5 part of compound probiotic fertilizer and 0.1-0.5 part of plant growth promoter. The method for culturing selenium-rich organic edible fungi by using the culture medium comprises the following steps: mixing the plant growth promoter and compound probiotic fertilizer, and dissolving in water to prepare a liquid; mixing the rest raw materials, adding the liquid, and fermenting to obtain the culture medium; and uniformly mixing a strain with the culture medium for inoculation, culturing for 10-15 days until the hypha are overgrown, and reinoculating the hypha. The culture medium has the advantages of reasonable component proportioning and high growth speed of hypha.

Description

technical field [0001] The invention relates to the field of cultivation of edible fungi, in particular to a culture material for selenium-enriched organic edible fungi and a cultivation method thereof. Background technique [0002] Since the early 1980s, edible fungus cultivation has developed rapidly in China as a good project with small investment, short cycle time and quick results. The edible fungus industry is a short-term and fast rural economic development project integrating economic benefits, ecological benefits and social benefits. Edible fungi are also a kind of organic, nutritious and healthy green food. The development of edible fungus industry meets the needs of people's consumption growth and sustainable agricultural development, and is an effective way for farmers to get rich quickly. Based on the above reasons, the field of edible mushroom cultivation is booming. [0003] In the prior art, most commonly used culture materials for planting edible fungus ar...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, most commonly used culture materials for planting edible fungus are sawdust of poplar, willow, elm, maple, fig, fig, etc. However, the compost made of these substances needs to be sterilized before sowing, especially under the condition of relatively high temperature, it is necessary to pay attention to timely sterilization to prevent the infection of miscellaneous bacteria. The practice of creating an aseptic environment for the growth of edible fungi is complicated, the production efficiency is low, and the aseptic effect is difficult to be completely guaranteed when the material bag is moved many times, and the sterilized culture material is completely harmful to the re-infection of harmful bacteria. no resilience

Conventional sterilization methods are not only labor-intensive, time-consuming and energy-consuming, but the key point is that they do not meet the requirements of ecological industrial production

In addition, the bacteria are easy to age during the planting process, and the basically grown hyphae cannot be reused as seeds, which is very wasteful

In this way, not only the operation steps of the cultivation method are cumbersome, but the hyphae cannot be recycled, which increases the operation cost virtually, and because a large amount of grain powder and high-nitrogen and high-phosphorus fertilizers are added to the culture material as auxiliary materials, This leads to competition between humans and animals for food, which further exacerbates the "contradiction between fungi and food". The ratio of ingredients is unreasonable, and the quality of the cultivated edible fungi is not high.
