Problems solved by technology

In terms of nutrients, xylose residue can be used to cultivate edible fungi, but there are still some problems as the main culture material of flat mushrooms: (1) xylose residue emits harmful gas, the pH value is low, and mycelia cannot grow; ( 2) The particle size of dross is small, and the air permeability is poor; (3) The carbon source contained in xylose dregs is rich, but there is no effective nitrogen source, etc.

Embodiment 1

[0019] Take 1 ton of xylose residue, add 40 kg of quicklime, adjust the pH value to 7.7, and then spread it in the sun to expose it to the sun, and turn it frequently until the water content of the xylose residue drops to 20%. The corncobs are crushed into particles with a particle size of 3-3.5 cm. Weigh 560 kg of pretreated xylose slag, 230 kg of corncob particles, 140 kg of bran, 4 kg of corn flour, 0.5 kg of gypsum powder, 2 kg of compound fertilizer, 0.4 kg of plant ash, and 0.4 kg of table salt, mix evenly, and add 1wt %lime water until the water content of the material is 65% and the pH value is 7.3. Then the pile is fermented, and the top of the pile is pricked with a walnut-thick wooden stick every 25-30cm for ventilation. When the temperature in the pile reaches above 65°C and lasts for 8 hours, turn over the pile. Ferment for 6 days, turn the heap 3 times during the period, until a large amount of white actinomycetes appear in the heap, and make a matrix. Use a 2...

Embodiment 2

[0021] Take 1 ton of xylose residue, add 40 kg of quicklime, adjust the pH value to 7.7, and then spread it in the sun to expose it to the sun, and turn it frequently until the water content of the xylose residue drops to 20%. The corncobs were crushed into particles with a particle size of 2.5-3 cm. Weigh 640 kg of pretreated xylose slag, 270 kg of corncob particles, 160 kg of bran, 6 kg of corn flour, 1.5 kg of gypsum powder, 3 kg of compound fertilizer, 0.6 kg of plant ash, and 0.6 kg of salt, mix evenly, and add 1wt %lime water until the water content of the material is 65% and the pH value is 7.3. Then the pile is fermented, and the top of the pile is pricked with a walnut-thick wooden stick every 30-35cm for ventilation. When the temperature in the pile reaches above 70°C and lasts for 8 hours, turn over the pile. Ferment for 8 days, turn the heap 4 times during the period, until a large amount of white actinomycetes appear in the heap, and make the matrix. Use a 20cm...

Abstract

The invention discloses a method for oyster mushroom production with pretreated corn cob, which is used for producing culture matrix for oyster mushroom mainly from pretreated corn cob. Cost of the pretreated corn cob is reduced by more than 70% as compared with that of cotton seed hull, sawdust and corn cob, and accordingly production cost of the oyster mushroom is reduced. Biological conversion rate of the oyster mushroom cultivated on a large scale by the method is high, up to above 100%, the quality of the oyster mushroom is higher, and protein content of dried osier mushroom per 100g is 1.6g higher than that of dried oyster mushroom cultivated with the corn cob. The pH value of mushroom bag residue from oyster mushroom produced mainly from pretreated corn cob is 6.5-7.0, the mushroom bag residue contains 1.108% of nitrogen, 0.926% of phosphorus (P2O5) and 0.848% of potassium (K20), nutrient content of the mushroom bag residue is equivalent to that of common miscellaneous manure and has no negative effects after used as fertilizer returned to fields, physical and biological properties of soil are improved, virtuous cycle is formed in comprehensive use, and the problem of environment pollution is solved.

Description

technical field [0001] The invention relates to mushroom cultivation technology, in particular to a method for producing oyster mushrooms by using xylose residue as a raw material. Background technique [0002] Pleurotus ostreatus, also known as Pleurotus ostreatus, is one of the most widely cultivated edible fungi in my country. There are many raw materials suitable for the cultivation of Pleurotus ostreatus, such as sawdust, cottonseed husks, corncobs, crop straws, etc. However, in recent years, forest resources have become increasingly scarce, cottonseed husks and corncobs have been used in many ways, and crop straws have been crushed and returned to the field. , causing the cost of flat mushroom raw materials to increase day by day, it is imminent to develop new raw materials for flat mushroom cultivation. [0003] Xylose residue is the solid waste after extracting xylose from corncobs, wheat straw, etc. At present, there is no good waste utilization method for xylose ...
