Abstract

The invention discloses a preparation method of low-cost chicken-manure slow-release organic fertilizer. The preparation method includes: mixing, by weight, 15-25 parts of halloysite with 45-85 parts of water, performing hydrothermal reaction at 220-260 DEG C for 22-34 hours, centrifuging for separation, drying, adding 25-55 parts of hydrochloric acid, stirring for 25-55 minutes, standing for 25-45 hours, centrifuging, washing, drying, adding 35-65 parts of water, 3-6 parts of cellulose and 0.4-0.8 part of catalyst, stirring, performing hydrothermal reaction at 220-260 DEG C for 10-20 minutes, centrifuging for separation, washing, adding 3-7 parts of prefabricated microspheres, 25-55 parts of water and 15-45 parts of anhydrous ethanol, mixing, drying at 60-70 DEG C, grinding into powder, adding 100 parts of pre-fermented chicken manure and 1.5-2.5 parts of sterilizing deodorant, regulating water content to 7-9wt%, crushing to 60 meshes, evenly mixing, performing granulation, and drying at 45-55 DEG C to obtain the low-cost chicken-manure slow-release organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a preparation method of low-cost chicken manure slow-release organic fertilizers. Background technique [0002] With the development of my country's agricultural industrialization, the scale of chicken farming in the breeding industry continues to grow, and the chicken manure in the breeding base is also gradually increasing. The natural stacking of chicken manure, if it is not harmless, will pollute the ecological environment of the surrounding areas . The bio-organic fertilizer produced from chicken manure not only kills most pathogenic bacteria and eggs, reduces the occurrence of diseases and insect pests, but also has low production cost and cheap price; however, the slow-release effect of bio-organic fertilizer produced from chicken manure is poor at present, And the ability to retain water and fertilizer needs to be improved urgently.
