Pleurotus cornucopiae stock culture compatible product and preparation method of culture

Abstract

The invention provides a pleurotus cornucopiae stock culture. The pleurotus cornucopiae stock culture is characterized by taking corn kernels as main raw materials and sawdust and bagasse as auxiliary materials. The invention also provides a preparation method of the culture. Compared with sawdust cultures, the pleurotus cornucopiae stock culture has the advantages that I. the corn kernels are rich in nutrition, hyphae germinate early, the distribution area of germination points is large, the hyphae grow fast, and the bottle filling time is shorted; II. after corn seed kernels are inoculated into cultivated species, the corn kernels can still serve as nutritional sources for the hyphae to grow, and the hyphae show good growth vigour and strong vitality; III. the corn kernels are uniform, and the expanding propagation rates are twice-three times higher than the expanding propagation rates of the sawdust strains; and IV. by adding the auxiliary materials, namely sawdust and bagasse, the water binding capacity of the culture is improved, and the corn seed kernels are prevented from being aged and hardened, so that the storage lives of the strains are prolonged.

Description

technical field [0001] The content of the present invention includes the composting material compatibility of the original species of jitake mushrooms and the preparation method of the composting material, which belongs to the field of producing edible fungus strains. Background technique [0002] Jiji mushroom, also known as Pleurotus chinensis, Pleurotus purpurea, is one of the rare edible fungi newly developed in my country in recent years. [0003] The sporocarp of Jiji mushroom grows in tile-like clusters, the stalk is white, the cover is lead gray, the flesh is thick, the texture is crisp and tender, and the taste is delicious. It not only contains protein, sugar, fat, vitamins, iron, calcium and other trace elements, but also contains types of amino acids. It is also very rich, especially containing 8 kinds of amino acids necessary for the human body. It is a healthy food with high nutrition and low calories. Long-term consumption can lower blood pressure and choleste...

Problems solved by technology

There are two deficiencies in the original species of Jiji mushroom: on the one hand, mycelium is easy to form lumps, and it must be mashed when used. During the mashing process, the mycelium is seriously damaged, and the fungus will germinate after being transferred to a cultivated species. slow; on the other hand, the strains of wood chips are prone to shrinkage and aging, and the application period is short
