Method of cultivating selenium enrichment oyster mushroom

Abstract

The invention relates to the technical field of oyster mushroom cultivation, and in particular relates to a method of cultivating selenium enrichment oyster mushroom. The cultivation of the oyster mushroom comprises the steps of 1, the preparation of the cultivation medium; 2, the planting; 3, the bacterium bag cultivation; and 4, the mushroom fruiting management. In the process of preparing the culture medium, through the addition of inorganic selenium and diatomaceous earth for promoting the absorption of selenium, the conversion of inorganic selenium into organic selenium can be achieved, and the organic selenium can be gathered in the oyster mushroom body, the production efficiency of selenium enrichment oyster mushroom is improved, meanwhile selenium poisoning is not possible because of the excessive selenium, in the mushroom-management process, herbal medicine liquids are also used for sterilization, disinfection and the warding off of the insects, the growth of oyster mushroom is further protected, meanwhile no pesticide residues can cause threats to human health, and the method is an environmentally friendly, economical and efficient method for selenium enrichment mushroom cultivations.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of Pleurotus ostreatus planting, in particular to a cultivation method of selenium-enriched Pleurotus ostreatus. [0003] 【Background technique】 [0004] Selenium is an essential trace element for the human body. It is called "the effective element of life" or "the fifth element of life" because of its unique functions of prevention, treatment and health care. Studies have shown that selenium deficiency in the human body can lead to Keshan disease, cancer, cataract, cardiovascular disease, diabetes, AIDS, etc. Selenium supplementation can eliminate free radicals in the body, reduce whole blood viscosity and plasma viscosity; selenium supplementation is beneficial to promote children's growth and development; Selenium supplementation for the elderly can prevent diseases such as arteriosclerosis and cerebral thrombosis. Selenium supplementation has obvious preventive and preventive effects on cancer a...

Problems solved by technology

[0005] Pleurotus ostreatus is delicious, nutritious, easy to cultivate, high in yield, high in price and good in economic benefits. It is also rich in proteoglycans, which has a strong inhibitory effect on cancer cells and can enhance the immune function of the body. It is widely loved food However, Pleurotus ostreatus also has a strong selenium-enriching ability, which is a natural selenium carrier. It is a simple and effective method to produce selenium-enriched Pleurotus ostreatus with Pleurotus ostreatus. One way is to spray selenium solution on the fruiting bodies of Pleurotus ostreatus. This method can make Pleurotus ostreatus contain selenium, but selenium exists in the form of inorganic matter, not in the form of organic matter. The growth cycle of mushrooms is fast, and inorganic selenium is picked before it can be converted into organic selenium, which will affect the health of the eater, and it cannot be absorbed by the human body, which cannot achieve the original intention of selenium-rich food; and, another way It is to add inorganic selenium in the culture medium, and convert the inorganic selenium in the culture medium into organic selenium through the metabolism of oyster mushrooms. As a result, the utilization rate of selenium in the selenium-enriched cultivation process is not high, and then a better enrichment effect cannot be achieved. Moreover, in the cultivation process of selenium-enriched Pleurotus ostreatus, there is currently no relevant plant-sourced insecticides on Pleurotus ostreatus.
