preparation example Construction

[0046] Such as figure 1 Shown, the first aspect of the present invention provides a kind of preparation method of stalk-manure micro-storage fertilizer, it may further comprise the steps:

[0047] 1) The straw silkizing machine 100 is used to process the straw on the spot to obtain straw silk, and measure the natural moisture content of the straw silk. The straw silk is composed of water and dry matter of the straw silk.

[0048] 2) Dry-wet separation and impurity removal are carried out on the feces, and the dry matter and wet matter of the feces are separated, and the natural moisture content of the manure is measured. The manure is composed of dry matter and wet matter of the manure. The mass of impurities in the medium is negligible; The manure in the subsequent steps refers to the manure after impurity removal, including manure dry matter and manure wet matter;

[0049] 3) According to the preset moisture content requirements of the fertilizer source material and the...

Embodiment 1

[0063] 1) The corn stalks are silked in situ by a straw silking machine to obtain corn stalk silk, and the natural moisture content of the corn stalk silk is measured to be 60%;

[0064] 2) Cow dung is subjected to dry-wet separation and impurity removal treatment, and the dry matter and wet matter of cow dung are obtained by separation, and the natural moisture content of cow dung is measured to be 60%;

[0065] 3) According to the preset fertilizer source material moisture content of 60% and the preset ingredient ratio of straw dry matter to manure dry matter of 2:3, combined with the natural moisture content of corn straw silk measured in step 1) and step 2) The measured natural moisture content of cow dung determines the amount of corn stalks and cow dung;

[0066] 4) Weighing 40 kg of corn stalks and 60 kg of cow dung respectively, and stirring and mixing the corn stalks and cow dung to obtain fertilizer source materials;

[0067] 5) Spray Bacillus licheniformis on the f...

Embodiment 2

[0069] 1) The corn stalks are processed into silk by using a straw silking machine to obtain corn stalk silk, and the natural moisture content of the corn stalk silk is measured to be 50%;

[0070] 2) The cow dung is subjected to dry-wet separation and impurity removal treatment, and the dry matter of cow dung and the wet matter of cow dung are separated, and the natural moisture content of the cow dung is measured to be 50%;

[0071] 3) According to the preset fertilizer source material moisture content of 50% and the preset ingredient ratio of straw dry matter to manure dry matter of 3:2, combined with the natural moisture content of corn straw silk measured in step 1) and step 2) The measured natural moisture content of cow dung determines the amount of corn stalks and cow dung;

[0072] 4) Weighing 30 kg of corn stalks and 20 kg of cow dung respectively, and stirring and mixing the corn stalks and cow dung to obtain fertilizer source materials;

[0073] 5) Spray Bacillus ...

Abstract

The invention discloses a straw-excrement microbial silage fertilizer and a preparation method thereof. The preparation method disclosed by the invention comprises the following steps: carrying out in-situ filamentation treatment on straws by adopting a straw filamentation machine to obtain straw filaments, and measuring the natural moisture content of the straw filaments; carrying out dry-wet separation and impurity removal treatment on the excrement to obtain dry excrement substances and wet excrement substances, and measuring the natural moisture content of the excrement; according to a preset fertilizer source material moisture content requirement and a preset burdening ratio requirement of the straw filaments dry matter and the excrement dry matter, determining the use amounts of thestraw filaments and the excrement in combination with the natural moisture content of the straw filaments and the natural moisture content of the excrement; respectively weighing the straw filaments and the excrement, and stirring and mixing the straw filaments and the excrement to obtain a fertilizer source material; spraying a microbial agent to the fertilizer source material, compressing the fertilizer source material into blocks according to a preset compression ratio, and briquetting and bagging the materials, and decomposing and fermenting the materials to obtain the straw-excrement micro-storage fertilizer. The method is easy to operate, the utilization rate of straw and excrement is increased, and resource waste and environmental pollution are reduced.

Description

technical field [0001] The invention relates to the field of utilization of agricultural organic waste, in particular to straw-manure micro-storage fertilizer and a preparation method thereof. Background technique [0002] Agricultural organic waste mainly includes straw and livestock and poultry manure. At present, although projects such as standardized construction of farms, biogas engineering construction, and comprehensive utilization of straw have been carried out, the overall effect of these measures is not significant due to the lack of systematic design and joint efforts. At present, problems such as cross-flow of livestock and poultry manure in rural areas and indiscriminate burning of straw are still prominent. Especially in some large farming counties, various types of farming waste are concentrated and produced in large quantities, and the local environment is under increasing pressure. The need to strengthen the integrated development of farming and breeding is ...
