Cultivation material capable of preventing growth of Neurospora in Pleurotas sapidus and preparation method thereof

Abstract

The invention discloses a cultivation material capable of preventing growth of Neurospora in Pleurotas sapidus and a preparation method thereof. The cultivation material contains 89 to 92% of cottonseed shell, 2 to 5% of corn flour, 2 to 3% of wheat bran, 1 to 2% of calcium sulfate and to 2% of quicklime. The preparation method comprises the following steps: uniformly mixing the above-mentioned raw materials, adding water according to a ratio of the dry mixture to water of 1: 1.3 and adjusting a pH value to 10 to 11; piling up the culture material to form a material pile, perforating the material pile with a large stick with a diameter of 5 to 8 cm, wherein distance between holes is 40 cm, covering the material pile with a straw mat, turning the material pile over in 24 h after the temperature of the material pile reaches 55 DEG C and spraying limewash with a weight percentage of 1% onto the material pile until the water content of the material pile is 65 to 68%; turning the material pile over twice to three times, bagging the material pile after completion of fermentation, covering a bag pile with a plastic film, introducing steam into the bag pile from the center of the bottom of the bag pile so as to allow the temperature of the center of the bag pile to be 80 DEG C, maintaining the temperature for 1 h and then carrying out natural cooling so as to obtain the cultivation material. The cultivation material enables the contamination rate of a fungus sack to be decreased to 0.3% or below, prevents growth of Neurospora in Pleurotas sapidus and has wide practicality.

Description

technical field

[0001] The present invention relates to the technical field of fungi preparation. In particular, the present invention relates to the technical field of preventing the growth of Neurospora in Ferulae mushrooms. Background technique

[0002] Ferulae mushroom (Pleurotus ferulae Lenzi), also known as Pleurotus ferulae and Mushroom ferulae, belongs to Basidiomycotina, Phytomycota, Agaricaceae, Pleurotaceae, Pleurotus genus, is a large-scale fleshy agaric with good quality. In my country, it is mainly distributed in Xinjiang and has a high use value.

[0003] The raw materials for the production of Ferula ferulae are often farmland wastes such as cottonseed husks, sawdust, corncobs, and crop straws. These raw materials are often stacked outdoors and are prone to mildew. The compost for cultivating feruli is usually cultivated with raw material, fermented material and clinker. To be specific, raw material cultivation Ferula ferulae is directly inoculated and cul...
