Dry cow dung powder organic fertilizer, preparation method thereof and application thereof

Abstract

The invention discloses a dry cow dung powder organic fertilizer. The dry cow dung powder organic fertilizer which is granular in shape is prepared from the following components, by mass, 78-90% of dry cow dung powder, 8-20% of biological organic matters and 1-3% of an adhesive. The invention also discloses a preparation method of the dry cow dung powder organic fertilizer. The preparation method comprises the following steps: 1, collecting fresh cow dung, air-drying it in the outdoor, dehydrating it, drying it in an oven, and crushing it to obtain the dry cow dung powder; 2, mixing the dry cow dung powder with the biological organic matters and an organic nitrogen-phosphor-potassium fertilizer according to above mass proportions to obtain a mixture; and 3, adding the adhesive to the obtained mixture, uniformly mixing them, and granulating them by an extrusion granulator or a disc granulator to obtain the dry cow dung powder organic fertilizer. The dry cow dung powder organic fertilizer of the invention, which can be widely applied to production plantations of capsicum, wheat and corn, can obviously improve the soil organic matters and the soil fertility, reduce the fertilizer dosage and improve the soil structure, and has the advantages of small application cost, stable quality, high quality and the like.

Description

technical field [0001] The invention relates to a crop fertilizer and its preparation method and application, in particular to an agricultural organic fertilizer and its preparation method and application. Background technique [0002] With the rapid development of the cattle industry, cattle manure pollution has become a major problem. According to relevant data, in some places, the pollution of cow dung to the environment has exceeded the total amount of industrial pollution, and some are even as high as more than 2 times. A dairy cow produces more than 7 tons of manure every year, and a yellow cow produces between 5 and 6 tons of manure. Due to the general lack of attention to the treatment of cow dung in various places, there are basically no cow dung treatment facilities in some places where cattle raising is relatively concentrated, which leads to the random dumping and storage of cow dung; especially in the south, every summer, cow dung The place where it is piled u...

Problems solved by technology

Due to the general lack of attention to the treatment of cow dung in various places, there are basically no cow dung treatment facilities in some places where cattle are raised more intensively, which leads to the random dumping and storage of cow dung; especially in the south, every summer, cow dung The place where it is piled up is full of stench, which not only has a negative impact on the normal life of the surrounding residents, but also the cow dung is the source of the breeding and reproduction of various bacteria and pathogens, which also has a serious impact on the breeding population
