Selenium-enriched ganoderma lucidum planting culture medium

Abstract

The invention discloses a selenium-enriched ganoderma lucidum planting culture medium, which is prepared from the following raw materials in parts by weight: 8 to 12 parts of sophora japonica powder, 3 to 5 parts of purple sweet potato anthocyanin, 4 to 6 parts of corn flour, 1 to 2 parts of selenic acid amino acid rare earth, 1 to 3 parts of sodium selenite, 0.1 to 0.6 part of alkyl sulfonic ester type surfactants, 1 to 5 parts of 6-benzyl aminopurine, 5 to 10 parts of disodium ethylenediaminetetraacetate dihydrate, 1 to 3 parts of attapulgite, 5 to 15 parts of peanut shell, 1 to 3 parts of vinasse powder, 1 to 3 parts of egg shell, 0.5 to 2 parts of tobacco and 1 to 3 parts of melia azedarach fruits. The sufficient selenium source is provided for the growth of the ganoderma lucidum; in addition, the selenium source is safe and reliable; the organic selenium content in the culture medium is high, so that the ganoderma lucidum is enabled to absorb the sufficient organic selenium in the growth process; the selenium content in the ganoderma lucidum body is improved; the nutrition value and the medical value of the ganoderma lucidum are improved.

Description

technical field [0001] The invention relates to ganoderma planting technology, in particular to a selenium-enriched ganoderma planting medium. Background technique [0002] Ganoderma lucidum has high medicinal value, and it is hailed as a fairy grass in legends, symbolizing auspiciousness, wealth, health and longevity. Ganoderma lucidum is actually a kind of saprophytic fungus. Wild Ganoderma lucidum grows on the rotten stumps, stumps and roots of broad-leaved trees in the forest, and is very rare. However, my country has been studying the artificial cultivation of Ganoderma lucidum for decades, and has successfully studied the growth characteristics, artificial culture strains and artificial cultivation methods of Ganoderma lucidum: the biggest difference between Ganoderma lucidum and other fungi lies in the growth of its mycelium and fruiting bodies. The optimum temperature is 15°C-35°C with little difference, and can grow, while the optimum temperature is about 25-28°C, a...

Problems solved by technology

But unfortunately, in the current liquid culture technology, the culture medium is all put into the culture tank, and the culture medium contains insoluble solids, which release enzymes in the liquid culture process, causing the culture liquid to have peculiar smell, and causing mycelium, insoluble solids It is difficult to separate from the culture medium; in addition, most of Ganoderma lucidum cultivation adopts the methods of wood chip cultivation and basswood cultivation, which need to consume a large amount of wood resources, which is not conducive to the protection of the ecological environment. The large-scale development of wood chip cultivation and basswood cultivation edible fungus production is subject to Forest resources are limited, so the "bacteria forest contradiction" is becoming more and more prominent
