Method for preparing chicken leg mushroom cultivation medium by fermentation and sterilization two in one technique

Abstract

The invention relates to a method for preparing the culture substrate of coprinus comatus by utilizing two-in-one technology of fermentation and sterilization. The components of the culture substrate comprise sediments, herb residues, wheat straw hood or / and straw powder, wheat bran, pulverized lime, urea and calcium superphosphate. The culture substrate is characterized in that: the sediments and the herb residues are adopted as main raw materials, the wheat straw hood or straw is adopted as a complement so as to achieve the complementation of substrate nutrient and thick and thin grains, namely, achieve the purposes of normal spawn running, normal fruiting and stable output; simultaneously, the wheat straw hood or straw can be greatly saved and the sediment contamination is reduced. Theinvention also provides a two-in-one preparing method of fermentation and sterilization for the culture substrate. By using the culture substrate of coprinus comatus, the cost is reduced by 80 percent compared with raw materials of cotton seed hulls, and is reduced about 60 percent compared with the use of raw materials of stalks of straw powder and the like.

Description

technical field [0001] The invention relates to a comprehensive utilization method of biogas residue and traditional Chinese medicine residue raw materials, in particular to a method of using biogas residue and traditional Chinese medicine residue as main raw materials and adopting fermentation and sterilization two-in-one technology to prepare Coprinus comatus cultivation substrate, which belongs to the utilization of new resources The technical field for obtaining the cultivation substrate of Coprinus comatus. technical background [0002] Coprinus comatus belongs to the grass rot fungus, and because of its special biological characteristics, it has the special trait of "no mushrooms without covering the soil"; the main strains currently being cultivated are large, medium and small, and pure white; The production of Coprinus comatus in my country started mainly from the mid-1990s of the last century. Due to the rapid popularization of technology, the total output has increa...

Problems solved by technology

[0003] However, good market conditions and prospects have made traditional Coprinus comatus cultivation substrates such as cottonseed husks, waste cotton dregs, and corncobs increasingly tense and prices have risen sharply. Rapid increase, the above-mentioned resources are increasingly tense, and the cultivation cost is rapidly increased, which makes the cultivation benefit decline sharply, and because of the shortage of raw materials, the smooth development of Coprinus comatus production is restricted; on the other hand, large-scale wineries, alcohol factories, etc., while making great use of distiller's grain resources to build biogas, a large amount of biogas residues are produced. As a new resource, the utilization rate of biogas residues is low under the current conditions, and it forms de facto secondary pollution; in addition, traditional Chinese medicine is a national treasure. A large amount of traditional Chinese medicine slag in chemical production is directly dumped as waste or landfilled, causing serious secondary pollution to the environment, soil, and groundwater resources. While polluting the environment, a large resource is wasted; using the above two slags Prepare the Coprinus comatus cultivation substrate as the main raw material, add some straw or wheat straw and other straw materials, and make it produce benefits on the basis of extending the utilization chain of the two slag resources; adapt to the requirements of environmental protection economy and development of circular economy, and meet the requirements of new energy, new The policy of material development and utilization is the development direction of comprehensive utilization of biomass resources

[0004] Biogas slag has higher nutrient components and organic matter content, but the particles are finely broken, and there are problems such as severe poor ventilation in the substrate, long bacteria-producing time, and high pollution rate of bacteria bags when used as a Coprinus comatus cultivation substrate alone; as disclosed in Chinese patent document CN101125773 (200710014827.8) A method of using biogas slurry to cultivate Coprinus comatus uses straw as the main raw material, and with the expanded use of this type of raw material, resource problems have become increasingly prominent; and plant-based traditional Chinese medicine dregs have low effective nutrients and thick and long particles, so they can be used alone When edible fungus cultivation substrate, there are many problems such as insufficient nutrition, too thick substrate, large space in the substrate, low water holding rate of the substrate, etc., the substrate shrinks severely after the fungus is produced, and the fruiting efficiency is low, such as Chinese patent document CN1918963 (application number 200610068623.8 ) discloses a method for producing edible fungus cultivation material by using Chinese medicine dregs. The method of fermenting traditional Chinese medicine dregs and corncobs makes the original low-nutrient substrate lose a large amount of nutrients during the fermentation process, making the cultivation effect unsatisfactory. Moreover, over-ripe traditional Chinese medicine dregs are prone to a large amount of mold contamination such as Neurospora and Trichoderma during the fermentation process, resulting in extremely unstable cultivation results and low yields, and because Neurospora and Trichoderma are difficult to control, making cultivation sites and The production of edible fungi in its surrounding areas is unsustainable, does not meet the requirements of industrialization development, and does not meet the requirements of sustainable economic development
