Embodiment 1

[0037] Take 500 kg of powder slag, add 25 kg of quicklime, adjust the pH value to 8.5 (use pH test paper to directly insert into the solid material to measure the pH value), and then spread it in the sun and expose it to the sun, turning it frequently until the water content of the powder slag drops to 20 %until. Weigh 100 kg of pretreated powder slag, 800 kg of cottonseed hulls, 40 kg of lime, 35 kg of compound fertilizer, 20 kg of plant ash, and 5 kg of urea and mix evenly, add 1wt% lime water until the water content of the material is 65% and the pH value is 7.5 until. Then the pile is fermented, and the top of the pile is pricked with a wooden stick every 25-30cm for ventilation. Turn the pile when the temperature in the pile reaches 65°C or above and lasts for 8 hours. Ferment for 6 days, turn the heap 4 times during the period, a large number of white actinomycetes appear in the heap at the end of the fermentation, and make the matrix. Use 18cm × 40cm × 0.03cm polyeth...

Embodiment 2

[0039] Take 500 kg of powder slag, add 25 kg of quicklime, adjust the pH value to 8.5, then spread it in the sun and expose it to the sun, and turn it frequently until the water content of the powder slag drops to 20%. Weigh 200 kg of pretreated slag, 700 kg of crushed corn stalks, 45 kg of lime, 30 kg of compound fertilizer, 20 kg of plant ash, and 5 kg of urea and mix evenly. Add 1wt% lime water until the water content of the material is 65%, pH value up to 7.5. Then the stacking material is fermented, and the top of the stacking material is pricked with a wooden stick every 25-30cm to make a ventilation hole. When the temperature in the pile reaches above 65°C and lasts for 8 hours, turn over the pile. Ferment for 7 days and turn the pile 4 times during the period to make the matrix. Use 18cm × 40cm × 0.03cm polyethylene plastic bag to pack the substrate, while packing the bag, inoculate the two ends and the middle of the bag with the strains of Pleurotus pridis by the we...

Abstract

The invention relates to a method for producing pleurotus cornucopiae by taking slag powder as a cultivation material. A raw material comprises the components in parts by weight as follows: 5-20 parts of slag powder, 70-85 parts of a substrate raw material, 0.3-0.5 part of urea, 2-4 parts of a compound fertilizer, 2-5 parts of lime and 1-2 parts of plant ash. In the raw material of a culture substrate, maize straw or cottonseed hulls is (are) replaced with the slag powder, so that the cost of the culture substrate is reduced obviously. According to the method for producing the pleurotus cornucopiae, the operation is simple, the output of the pleurotus cornucopiae is increased greatly, the problem that the slag power pollutes the environment is solved, waste is turned into wealth, and the slag power is used, taken as a fertilizer and then returned to the field.

Description

technical field [0001] The invention relates to the cultivation technology of mushrooms, in particular to a method for producing mushrooms with powder residue as cultivation materials, and belongs to the technical field of resource reuse and edible fungi. Background technique [0002] Vermicelli is one of the common foods in our country, the main raw materials are sweet potatoes and mung beans. There are many vermicelli production and processing enterprises in our country. According to industry estimates, the annual production of vermicelli produces more than 1.5 million tons of powder residue waste. Zhaoyuan City, Shandong Province is the main production area and distribution center of "Longkou vermicelli". There are 167 vermicelli production and processing enterprises in the city, and the vermicelli production produces 350,000 tons of vermicelli waste every year. Over the years, most of these powder residues have been discarded as waste, causing serious pollution to the e...
