Problems solved by technology

[0008] Second, the amount of corn stalks returned to the field is extremely limited.
[0012] One is that although basically all of them are returned to the field, the straw returned to the field cannot be completely decomposed before planting in the second year; the soil is soil, and the straw that has not been crushed is still straw, which directly affects the entry and germination of the sown seeds, resulting in a serious shortage of seedlings in the field, thus Affect yield
[0013] The second is that the straw is directly returned to the field, and the pathogens that cause corn diseases are also directly returned to the field with the straw, which makes the damage of the disease more serious year by year, and has already harmed the sustainable production of farmland.
On the day of burning, thick smoke covered the sky, and the visibility of the expressway was less than 100 meters, which brought serious pollution to the environment

Embodiment 1

[0029] The process of composting corn stalks and livestock and poultry manure in the north to produce ecological organic fertilizer is as follows:

[0030] Stack retting location: the center of the continuous corn field. Use a forklift to mix corn stalks and fresh livestock and poultry manure with strains, turn the pile once with a compost turning and crushing machine, and ferment the stack. When the temperature rises above 60 degrees, turn the pile for the second time. And so on, just turn over 3-4 times. When the lowest temperature in the north drops to about 5 degrees, turn to a large pile (height of more than 2 meters, unlimited length and width) to survive the winter.

[0031] Process Description:

[0032] Formula: mass%

[0033] Fresh livestock manure: 20-50%;

[0034] Corn stalks with a length of 10-20 cm: 80-50%;

[0035] Strains: 0.1%.

[0036] The forklift adds moving materials and basically mixes well;

[0037] Use a forklift to make piles in turn with a heig...

Embodiment 2

[0049] The process of producing ecological organic fertilizer by retting rice straw and chicken manure in the north is as follows:

[0050] Stacking retting location: in the middle of continuous paddy fields. Use a forklift to mix rice straw, fresh chicken manure and strains, turn the pile once with a compost turning and crushing machine, and ferment the pile. When the temperature rises above 60 degrees, turn the pile for the second time. And so on, just turn over 3-4 times. When the lowest temperature in the north drops to about 5 degrees, turn to a large pile (the pile height is more than 2 meters, and the length and width are not limited) to survive the winter.

[0051] Process Description:

[0052] Formula: mass%

[0053] Fresh chicken manure (moisture content about 72%): 20-50%;

[0054] Rice straw with a length of 10-20 cm: 80-50%;

[0055] Strains: 0.1%.

[0056] The forklift adds moving materials and basically mixes well;

[0057] Use a forklift to make piles in...

Embodiment 3

[0067] Raw material is with embodiment 1, is as follows according to existing organic fertilizer production process:

[0068] Straw pre-treatment: straw collection, transshipment, and crushing, equivalent to about 300-400 yuan per ton of fertilizer straw.

[0069] Ingredients-mixing-stacking and fermentation-turning-stacking-after-ripening-testing-sieving-packaging-finished product storage.

[0070] Fertilizer production sites can only be manufacturers approved by relevant ministries.

[0071] Description of the process: Mix the ingredients, adjust the moisture to 60%, adjust the carbon-nitrogen ratio to 20-30:1, use mechanical mixing to uniformly stack and ferment, and after 7-8 days, when the fermentation temperature rises above 60°C, turn over The stacker turns over the pile repeatedly (20 days, once every two days), sampling and testing, qualified products are packaged, and finished products are put into storage. The whole production cycle is 27-28 days. The fertilizer ...

Abstract

The invention discloses a corn straw stack retting fermentation ecological organic fertilizer returned to a field and a production method thereof, and relates to the technical field of microbial organic fertilizer preparation. The corn straw stack retting fermentation ecological organic fertilizer consists of the following raw materials: a fermentation raw material and a composite strain, the fermentation raw material comprises fresh livestock and poultry manure and corn straw. The raw materials are taken according to a certain ratio and processed according to the production method for the corn straw stack retting fermented ecological organic fertilizer returned to the field, so that the preparation can be completed. After the technical scheme is adopted, the invention has the beneficial effects that centralized on-site stack retting and on-site field returning treatment are carried out in the center of a large planting field, so that costs for transferring, crushing and field returning of straw are greatly saved. The straw returning cost per mu can be controlled within 150 yuan.

Description

technical field [0001] The invention relates to the technical field of microbial organic fertilizer preparation, in particular to a corn stalk composting fermentation ecological organic fertilizer returning to the field and a production method thereof. Background technique [0002] There are mainly two methods for returning corn stalks to the field: one is to return the corn stalks to the field as organic fertilizer, and the other is to return the corn stalks directly to the field. [0003] 1. The process of returning organic fertilizer from corn stalks to the field is as follows: [0004] Ingredients—mixing—stacking and fermentation—turning piles—after ripening—testing—sieving—packing—finished product storage—organic fertilizer returning to the field. [0005] Description of the process: using solid waste from livestock and poultry breeding plus corn stalks (crushed) and strains, with a reasonable formula to make the water reach 50-60%, and the carbon-nitrogen ratio adjust...
