Problems solved by technology

Cultivation of shiitake mushrooms in bags with medium has the disadvantages of concentrated nutrition in the early stage and insufficient nutrients in the later stage, and is affected by the high temperature in the shed, and the water in the medium evaporates quickly and easily loses water. It is an important research topic to increase the yield of shiitake mushrooms as much as possible while ensuring the quality of the medium formula that can supplement the release of nutrients in the later stage.

Abstract

The invention discloses a culture medium for high-yield shiitake cultivation and relates to an edible mushroom cultivation technology. The culture medium is prepared from, by weight, 35-45 parts of wood bits, 17-25 parts of straw, 5-12 parts of cobs, 15-25 parts of wheat bran, 2-4 parts of quick lime, 1-2 parts of gypsum, 2-5 parts of eggshell, 5-10 parts of sugar beet pulp, 1-3 parts of slow release synergist, 5-10 parts of paper mulberry leaves, 0.5-1 part of plant ash and 0.1-0.3 part of urea. The culture medium is balanced and rich in nutrition, has good ventilation and water retention properties, solves the problem of hypoalimentation in a later period of cultivation, is conductive to shiitake growth and accordingly improves the shiitake yield and quality, and the contents of proteinand total sugar of shiitakes cultivated by the culture medium are increased, and the cultivated shiitakes have thick flesh, fragrant smell and tender taste.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a medium for high-yield cultivation of shiitake mushrooms. Background technique [0002] Shiitake mushroom, known as "mountain delicacy" among the people, is a kind of cultivated fungus with both food and medicine. Traditional Chinese medicine theory believes that shiitake mushrooms are sweet, flat, and cool in nature and taste, and enter the liver and kidney meridians. Nutrients such as sulfur compounds and ergosterol have the functions of improving immunity, anti-virus, preventing and treating cancer, and protecting the liver. Shiitake mushrooms have high nutritional and health value. [0003] Our country has a long history of shiitake mushroom cultivation. With the advancement of science and technology and people's emphasis on health, the research and development of shiitake mushrooms has become increasingly in-depth. How to further improve the yield and qua...
