A kind of compost and preparation method for cultivating Pleurotus eryngii with Polygonum cuspidatum residue

Abstract

The invention discloses a culture compost for growing pleurotus eryngii by polygonum cuspidatum residues and a preparation method thereof. The culture compost is applicable for growing pleurotus eryngii in a liquid strain, and is prepared from polygonum cuspidatum residues, corncob, sawdust, bran, corn flour, bean pulp, lime and gypsum according to a ratio. The preparation method comprises the following steps: A, pre-treatment of a substrate, piling and fermenting polygonum cuspidatum residues and sawdust respectively for a week in advance, pre-wetting corncob by water, standing in air for later use, the corn flour, the bran and the bean pulp are all dry products, and packaging for later use; and B, weighing polygonum cuspidatum residues, sawdust, corncob, corn flour, bean pulp, lime and gypsum according to the ratio, mixing uniformly with water, stirring mechanically for 1h, adjusting the water content to 60-65%, wherein the pH (potential of hydrogen) is 6.5-6.8. By the factorization of the pleurotus eryngii, the production period is shortened greatly, and the cost is reduced; and the polygonum cuspidatum residues are the wastes of polygonum cuspidatum production, the resource is rich, the particle size is medium, the water retention property is high, through using the polygonum cuspidatum residues to grow pleurotus eryngii, the waste is turned into wealth, the waste of resource is reduced, and the economic benefit is improved.

Description

technical field [0001] The present invention relates to the technical field of cultivating edible fungi by using liquid strains, more specifically to a compost for industrially cultivating Pleurotus eryngii by using Polygonum cuspidatum residue, and also relates to a method for industrially cultivating Pleurotus eryngii by using Polygonum cuspidatum residue Preparation method of culture material. Background technique [0002] Polygonum cuspidatum, the name of traditional Chinese medicine, is the dry rhizome and root of Polygonum cuspidatum. Excavated in spring and autumn, removed fibrous roots, washed, cut into short sections or thick slices while fresh, and dried in the sun. Shiyan is one of the main production areas of Chinese knotweed. Along with the increase of Polygonum cuspidatum output, a large amount of Polygonum cuspidatum slag is produced annually, causing serious waste of resources. [0003] Pleurotus eryngii (scientific name: Pleurotus eryngii), its fruit body...

Problems solved by technology

However, liquid strains have certain requirements on the main materials such as sawdust in the compost. The germination point of liquid strains usually grows fast, but the penetrating power is not strong. Rapid growth on the surface of the culture material, the amount of mycelium inside the culture material is very small, which seriously affects the yield and quality of the strain
