Problems solved by technology

After the manure is fermented, it can be added to more than 45% in the cultivation of Agaricus bisporus. In the cultivation of small and medium-sized enoki mushrooms, Coprinus comatus, straw mushrooms, and golden blessing mushrooms, there are also reports on the application of manure addition. Contradictions such as competition for materials and mushroom marshes

Abstract

The invention relates to a functional pig dung modifier and a method for preparing a mushroom cultivation material by the utilization of modified pig dung. Raw materials of a modifier comprise, by weight, 60-80 parts of wormcast, 5-30 parts of calcium hydrate and 10-15 parts of potassium dihydrogen phosphate. The method comprises the following steps: adding the modifier into pig dung, adding a deodorant, uniformly stirring, carrying out a solid-liquid separation to prepare the modified pig dung, uniformly mixing the modified pig dung with cottonseed hull, soybean cake powder, lime powder, gypsum powder, light calcium carbonate, calcium superphosphate and urea, adding water and composting and fermenting so as to obtain the mushroom cultivation material. On the basis of maintaining acid-base balance of a system, the modifier, which is composed of wormcast, potassium dihydrogen phosphate and calcium hydrate, with the help of strong adsorption property of wormcast, effectively elutes viscous substances of pig dung and is beneficial to elution of substances such as antibiotics and heavy metals, etc. and is also conducive to desiccation and use of the raw materials. The mushroom cultivation material prepared by the above method has remarkable yield increase benefit and significant economic benefit.

Description

technical field [0001] The invention relates to a modifier and a cultivation material, in particular to a functional pig manure modifier and a method for using the functional modifier to treat large-scale pig farm manure to prepare mushroom cultivation base material, belonging to livestock and poultry manure resources utilization technology field. Background technique [0002] With the development of the livestock and poultry breeding industry, its specialization, intensification and scale are getting higher and higher. Because pig farm manure has the characteristics of high water content, strong fluidity, high viscosity, and serious pathogen damage, it has become the worst resource utilization type among livestock and poultry manure. In the current published patent literature, most of the research on the resource utilization of pig manure is aimed at the production of organic fertilizer from pig manure fermentation. For example, Chinese patent document CN102887738A (appli...
