Problems solved by technology

The sludge itself has a poor aggregate structure and a strong ammonia smell, so it cannot be directly applied to the production of mushrooms. Adding chaff and chaff, supplementing crude fiber, increasing the porosity, and fermenting to remove the ammonia smell. (Natural) loess has good viscosity, but poor air permeability , simple use cannot meet the needs of mushroom cultivation

preparation example Construction

[0031] The preparation method of Agaricus bisporus nutrient covering soil prepared by using domestic sludge and loess is characterized in that it comprises the following steps:

[0032] A. Sludge fermentation

[0033] Take domestic sludge and chaff chaff with a volume ratio of 5-6:1-2, mix and spread for 1-2 days; when the water content is 55%-65%, mix and spread the domestic sewage Mud and chaff and chaff are piled up for fermentation; when the water content drops to 40%-45% and the nitrogen content in the sludge drops to 0.28-0.4%, it is ready for use;

[0034] B. Processing loess

[0035] Spread the natural loess on the cement floor and expose it to the sun. When the water content is lower than 30%, break the exposed loess, and then spread the broken loess with a thickness of 30-40cm. Add 10-15kg of calcium superphosphate and 20-25kg of chaff and chaff to a cubic meter of natural loess and stir evenly to form the loess treatment material;

[0036] C. Preparation of nutrien...

Embodiment 2

[0061] Preparation of sludge: Take domestic sludge and chaff with a volume ratio of 6:1, mix and spread for 2 days;

[0062] When the water content is 65%, the domestic sludge and chaff after mixing and drying are sent to the fermentation tank to build a pile for fermentation. The height of the pile is 1.5 meters and the width is 1.2 meters. Tianhou was transferred to a tank for fermentation 4 times, and the pile-building fermentation time and the height and width of the pile after the transfer were the same as those of the previous one;

[0063] When the water content drops to 45%, the nitrogen content in the sludge drops to 0.4%, and the ammonia smell basically disappears, it is ready for use.

[0064] Preparation of loess treatment material: spread the natural loess on the cement floor and expose it to the sun. When the water content is lower than 30%, put the exposed loess into the machine to break it, and then spread the broken loess on the ground, and the thickness of th...

Embodiment 3

[0072] Preparation of sludge: Take domestic sludge and rice chaff with a volume ratio of 6:2, mix and spread for 1.5 days;

[0073] When the water content is 60%, the domestic sludge and chaff after mixing and drying are sent to the fermentation tank to build a pile for fermentation. The height of the pile is 1.3 meters and the width is 1.1 meters. The tank was fermented 3 times, and the pile-building fermentation time and the pile-building height and width after the transfer to the tank were the same as those of the previous one;

[0074] When the water content drops to 43%, the nitrogen content in the sludge drops to 0.36%, and the ammonia smell basically disappears, it is ready for use.

[0075] Preparation of loess treatment material: spread the natural loess on the cement floor and expose it to the sun. When the water content is lower than 30%, put the exposed loess into the machine to break it, and then spread the broken loess on the ground, and the thickness of the loes...

Abstract

The invention relates to a preparation method of agaricus bisporus nutritional casing oil made from domestic sludge and loess. The method includes: preparation of sludge, preparation of loess treatment material and preparation of nutritional casing oil. The invention can effectively solve the soil shortage problem in agaricus bisporus cultivation, also effectively solves the sludge utilization problem, carries out anaerobic fermentation and kills harmful pathogenic bacteria. And the prepared nutritional oil has the characteristics of good granular structure, large saturated water content, rich organic matters, unit area yield substantially increased by about 30% than the prior art, stable mushroom product quality, easily available raw materials, simplified process and low making cost, can be used as the nutritional oil for cultivation of agaricus bisporus and reach the green and pollution-free requirements of mushroom production.

Description

technical field [0001] The invention relates to a fungi nutrient soil cultivation technique, in particular to a method for preparing a bisporus nutrient covering soil prepared from domestic sludge and loess, and belongs to the field of edible fungus cultivation. Background technique [0002] Agaricus bisporus, also known as white mushrooms, mushrooms, and mushrooms, is a mushroom that is cultivated and consumed worldwide. It can be sold fresh, canned, or salted. The mycelium of Agaricus bisporus is also used as a raw material for medicine. China's Agaricus bisporus is most cultivated in Fujian, Shandong, Henan, Zhejiang and other provinces. Cultivation methods include mushroom house cultivation, greenhouse frame cultivation and greenhouse border cultivation. Different regions, different climatic conditions and different seasons can adopt their own cultivation methods. Agaricus bisporus ( Agaricus bisporlz) It is a fecal saprophytic fungus, a medium-low temperature mushr...
