Problems solved by technology

Due to the quality and turnover efficiency requirements of Pleurotus eryngii in factory production, generally only the first wet mushrooms are picked, and the biological conversion rate is only 85% to 90%. The waste mushroom bags are usually dried and used as biomass fuel for boilers Instead of coal fuel, but because the waste still contains rich carbon sources and nitrogen source substances that have not been completely decomposed, resulting in a great waste of resources
At present, although the industry has summed up a lot of experience in the recycling of edible fungus waste, such as using Pleurotus eryngii or Flammulina velutipes waste to cultivate other varieties of edible fungi such as oyster mushrooms and grass rot, the overall level is low and it is impossible to get rid of the constraints of traditional agricultural concepts. Restrictions have led to a single agricultural circular economy model, and the embarrassing problem that the waste of Pleurotus eryngii and Flammulina velutipes has been turned into other recycled waste, which cannot fully reflect the value of resource recycling

Embodiment 1

[0042] Pretreatment of raw materials:

[0043] Sawdust is sliced ​​and crushed and treated with an 8-mesh screen. The sifted sawdust needs to be piled for fermentation for more than 6 months. During this period, the pile will be turned over once every 15 days, and watering will be carried out once every 5 days to overflow the bottom of the pile. Without flow.

[0044] Corn cobs are dried until the moisture is below 13%, crushed and screened through an 8 mesh screen. The corn cobs need to be pre-wet for 12 hours before use. When the temperature is higher than 18℃, the surface of the pre-wet is sprinkled with lime and lime. The amount is based on the next day's production without rancidity and smell.

[0045] The corn flour and soybean meal powder are separately dried to make the moisture less than 13%, and then crushed by a 2.0 aperture grain crusher.

[0046] Pleurotus eryngii culture medium was prepared: corncob 28%; sawdust 20%; bagasse 12%; bran 20%; soybean meal 10%; corn flour 8...

Abstract

The invention relates to a method for circular utilization of agricultural waste materials and belongs to the technical field of agricultural waste material utilization. The method for circular utilization of agricultural waste materials includes the following steps of 1, adopting a pleurotus eryngii culture medium for culturing pleurotus eryngii, and obtaining first-level waste materials after first damp mushrooms are harvested; 2, adopting a pleurotus geesteranus culture medium for culturing pleurotus geesteranus, and obtaining second-level waste materials after first three damp mushrooms are harvested; 3, adopting an agaricus bisporus culture medium for culturing agaricus bisporus, and obtaining third-level waste materials after first six-eight damp mushrooms are harvested; 4, blendingthe third-level waste materials with pig manure to conduct pile fermentation, and obtaining organic fertilizer used for planting crops, wherein processing waste materials generated by the crops are used for preparation of the pleurotus eryngii culture medium in the step 1. By means of the method, the cost of raw materials for culture is greatly reduced, obtained pleurotus eryngii, pleurotus geesteranus, agaricus bisporus and crops are high in quality, and a technical industrial chain of novel agricultural circular economy can be formed.

Description

Technical field [0001] The invention relates to the technical field of agricultural waste utilization, in particular to a method for recycling agricultural waste. Background technique [0002] In recent years, with the adjustment of the edible fungus industry's own structure and market demand, the cultivation volume of Pleurotus eryngii has been increasing year by year. Due to the quality and turnover efficiency requirements of Pleurotus eryngii in factory production, generally only the first tidal mushrooms are picked, and the biological conversion rate is only 85% to 90%. The waste fungus bags are usually used as biomass fuel for boilers after drying. Instead of coal fuel, the waste is still rich in carbon sources and nitrogen sources have not been completely decomposed, resulting in a great waste of resources. At present, although the industry has summarized many edible fungi waste recycling experience, such as the use of eryngii mushroom or enoki mushroom waste to cultivate ...
