Embodiment 1

[0028] Such as figure 1 Shown, a kind of bio-organic fertilizer taking pig manure as raw material and preparation method thereof comprises the following steps:

[0029] Step (1): The components of the raw materials are: pig manure, 5% chicken manure of the total weight of the material, 0.2% of the fermentation agent, and 0.1% of the deodorant agent; % Enterococcus faecalis, 25% Trichoderma viridans, 30% Bacillus subtilis; the deodorizing bacteria are 15% Aspergillus niger, 25% Bacillus subtilis, and 35% Enterococcus faecalis. Use 0.5% urea or ammonium sulfate to adjust the C / N ratio to 25-30:1. Then adjust the pH value to 5.5 with 1.0% superphosphate of the total weight of the material. The moisture content was kept at 50%. After the material is fermented and decomposed and crushed through a 60-mesh sieve, 0.1% of the total weight of the material is added with Bacillus subtilis.

[0030] Step (2): stacking of fermented materials: use a forklift to turn the pile, the height...

Embodiment 2

[0036] A kind of bio-organic fertilizer taking cassava skin as raw material and preparation method thereof comprises the following steps:

[0037] Step (1): The components of the raw material are: pig manure, 15% chicken manure of the total weight of the material added after pig manure pretreatment, 0.3% fermentation agent, 0.2% deodorant agent; the fermentation bacteria is 35% by weight % Enterococcus faecalis, 35% Trichoderma viridans, 40% Bacillus subtilis; deodorizing bacteria are 25% Aspergillus niger, 35% Bacillus subtilis, 45% Enterococcus faecalis. Use 1.0% urea or ammonium sulfate to adjust the C / N ratio to 25-30:1. Then adjust the pH value to 8.5 with the superphosphate of 1.5% of the total weight of the material. The moisture content was kept at 60%. After the material is fermented and decomposed and crushed through an 80-mesh sieve, 0.2% of the total weight of the material is added with Bacillus subtilis.

[0038] Step (2): stacking of fermented materials: use a...

Embodiment 3

[0044] The bio-organic fertilizer prepared in Examples 1 and 2 is processed, accurately weighed 25kg / bag or 50kg / bag, and after putting into the product qualification certificate covered with the production date and inspector, carry out the sewing operation, and the packed Finished products are stored in storage.

[0045] The physical and chemical properties of the bio-organic fertilizer prepared by the method of the present invention are tested, and the quality meets the requirements of the "NY884-2012" standard for bio-organic fertilizers of the Ministry of Agriculture, as shown in Table 3.

Abstract

The invention provides a bio-organic fertilizer employing pig dung as a raw material and a preparation method therefor. The bio-organic fertilizer comprises the following steps: firstly, pig dung is pretreated, and then chicken manure, fermentation agents and deodorizing fungicides are added; the C / N ratio is adjusted to 25-30:1 by utilization of urea or ammonium sulfate, the pH value is adjusted to 5.5-8.5 by utilization of calcium superphosphate the moisture content is kept at 50-60%, the materials are subjected to fermentation decomposition and then are crushed and sieved and then functional microbial agents are added; secondly, fermentation is carried out by utilization of compost fermentation. The beneficial effects are that firstly, the prepared bio-organic fertilizer raises output and economic benefits of crops of watermelons, bananas and the like greatly; the prepared bio-organic fertilizer improves physical, chemical and biologic properties of soil effectively; the agricultural product quality is raised; fourthly, development of agriculture and animal husbandry circular economy is promoted.

Description

technical field [0001] The invention belongs to the technical field of recycling organic waste resources in agriculture and animal husbandry, and in particular relates to a bio-organic fertilizer using pig manure as a raw material and a preparation method thereof. Background technique [0002] Pig food is safe for the world. Pig production occupies an important position in my country's agricultural economy, accounting for a high proportion of the primary industry and animal husbandry, and is the main force to stabilize the "vegetable basket" of the market. In 2014, 475.92 million pigs were raised nationwide, and Guangxi, as a major pig breeding province, reached 24.666 million. Currently, Bobai County in Guangxi ranks second among the four major counties that sell more than 2 million pigs annually. [0003] The impact of the development of the pig industry on the ecological environment has become increasingly prominent. According to statistics, each pig emits 2.0-2.5 tons o...
