New method for producing pleurotus eryngii by means of asparagus stalks

Abstract

The invention provides a method for producing pleurotus eryngii by means of asparagus stalks. The method includes the steps of asparagus stalk preprocessing, material preparation, material mixing, inoculation, fermental cultivation and fruiting management, wherein in the asparagus stalk preprocessing step, fresh asparagus stalks are dried and smashed and then are steeped in so as to be softened and absorb water; asparagus stalk smashing means that the asparagus stalks are smashed into short asparagus stalks with the length of 0.5-1.5 cm; the asparagus stalks are steeped in the lime water with the concentration of 1-2% for 10-12 hours. The yield of pleurotus eryngii produced through the method is high, commodification is good, the production process is simple, operation controllability is high, and the pleurotus eryngii is suitable for factory-like, large-scale and standardized production. The asparagus stalks are utilized to replace saw dust and cotton seed hulls to serve as main raw materials for producing the pleurotus eryngii, the asparagus stalks are made profitable for resource utilization, the environment pollution problem caused after the asparagus stalks are harvested is solved, meanwhile production cost of the pleurotus eryngii is lowered, and high yield, high quality and high efficiency of the asparagus stalks are achieved in the production process.

Description

technical field [0001] The invention relates to a method for producing pleurotus eryngii, in particular to a new method for producing pleurotus eryngii from asparagus stalks. Background technique [0002] Asparagus, scientific name Asparagus officinalis Linn, is a perennial herbaceous plant of the genus Asparagus in the Liliaceae family (Liliaceae). It is fed on tender stems and has extremely high nutritional and health value. At present, my country's asparagus planting area has exceeded 100,000 ha, making it the world's largest asparagus producer. The edible part of asparagus asparagus tender stems only accounts for 23.5% of the total output, and the remaining 76.5% are stems. Although the stems are rich in nutrients, most of them are not fully utilized. The total amount of asparagus stems produced every year is about 5 million tons, most of which are often treated as waste by local farmers, resulting in a large waste of resources and damage to the ecological environment. ...

AI Technical Summary

Problems solved by technology

Pleurotus eryngii has a strong ability to decompose lignin and cellulose, and wood chips, cottonseed husks, corncobs, straw, etc. are usually used as main raw materials in production. However, edible fungi cultivated on cottonseed husks are increasingly affected by pesticide residues and harmful components. At the same time, the rise in prices has led to an increase in the production cost of edible fungi, and the contradiction between the forestry and edible fungus industries has become increasingly prominent
