A cold-warm substrate for cultivating Polyporus

Abstract

The invention discloses a cold-temperature matrix for cultivating agaric. The matrix specifically comprises the following components in parts by weight: 60-70 parts of cow dung, 15-30 parts of fallen leaves, 10-15 parts of fly ash, 3-5 parts of fine sand, 5-10 parts of scale stone powder and 1-3 parts of trace elements, wherein the cow dung is the completely decomposed fermented cow dung of which the water content is 1-8%, and 20-35% of bean straw powder is added during the decomposition process of the cow dung; the fallen leaves are from one or more than one of pine needle, poplar, apricot tree and pear tree, and preferably, the fallen leaves are dead leaves of which the water content is 20-35%; the leaves are collected, crushed and extruded, and then are fermented for 8-15 days in the presence of 10-15% of vinegar residue; the trace elements are manganese, iron, magnesium, zinc, copper and boric acid. The cold-temperature matrix disclosed by the invention is mainly prepared from the cold cow dung and the cow dung is subjected to splitting treatment by virtue of the fly ash, the scale stone powder and the fine sand, which have relatively large specific surface area, so as to ensure that the cow dung is in different interface structures, and the air permeability and porosity of the cow dung are increased; therefore the prepared matrix has the advantages of high air permeability, good water absorption and the like.

Description

technical field [0001] The invention belongs to the technical field of cultivation substrates, in particular to a cold-temperature substrate for cultivating Polyporus umbilicali. Background technique [0002] Polyporus polyporus, a medicinal fungus of the genus Polyporaceae of the order Polyporaceae. The fruiting body is edible when young, and the taste is very delicious. Its underground sclerotium is black and has various shapes. It is a famous Chinese medicinal material. It has the effect of diuresis and edema. Modern research shows that Polyporus polysaccharides contain anti-cancer polysaccharides, and its main components are 7.89% crude protein, 0.24% ether-soluble extract, 46.06% crude fiber, soluble sugar, etc. It also contains free and bound biotin, 2-Hydroxy-tetracosanoic acid and ergosterol are fungi with multiple uses in food and medicine. Polyporus has the characteristics of being cool, gloomy and humid, and afraid of drought. It grows well under the ground temp...

Problems solved by technology

However, using cow dung alone as the substrate will cause low nutrient levels, which can be supplemented by adding urea, nitrogen fertilizer, etc., but the addition of inorganic fertilizers will cause matrix compaction and poor water absorption.
