Problems solved by technology

However, in organic fertilizers, some human and animal feces usually contain various pathogenic bacteria, viruses, parasites, etc., and some weeds contain various diseases and insect pests and seeds, etc. Organic fertilizers will damage the soil without harmless treatment or improper application. structure, polluting agricultural products and the environment; therefore, in crop production, especially in the production of green food in protected areas, organic fertilizer manure should be prohibited from being put on the ground, and it must be specially treated to turn harmful into harmless
[0003] Traditional composting takes a long time. In order to promote the rapid fermentation and decomposing of natural organic substances, alkaline calcium substances, such as lime nitrogen, calcium magnesium fertilizer and other calcium fertilizers, are often used as ripening accelerators. The essence is an acid-base reaction. If too much alkaline calcium is added, the pH value will be too high, which will affect the quality and application effect of the organic fertilizer, and cannot effectively improve the unpleasant smell of the organic fertilizer

Embodiment 1

[0030] Raw materials: Weigh 8 kg of zeolite, 2 kg of light rare earth salts, 26 kg of ferrous sulfate heptahydrate, 4 kg of magnesium sulfate, 30 kg of peat, 20 kg of caragana powder, and 9 kg of sweet straw grains.

[0031] Preparation method: The above components are respectively pulverized to 100 mesh with a pulverizer. Firstly mix zeolite and lanthanide light rare earth salts evenly, then add ferrous sulfate heptahydrate, magnesium sulfate, peat, caragana powder and sweet straw grains, and mix well. The homogeneously mixed product is sealed and packaged in polyethylene bags with more than double layers, and stored in a cool, dry and ventilated place for use.

Embodiment 2

[0033] Accurately weigh 8 kg of zeolite, 0.1 kg of lanthanide light rare earth salts, 20 kg of ferrous sulfate heptahydrate, 2 kg of magnesium sulfate, 25 kg of peat, 15 kg of caragana powder, and 7 kg of sweet straw grains; Grind to 100 mesh with a pulverizer. Firstly mix zeolite and lanthanide light rare earth salts evenly, then add ferrous sulfate heptahydrate, magnesium sulfate, peat, caragana powder and sweet straw grains, and mix well. The homogeneously mixed product is sealed and packaged in polyethylene bags with more than double layers, and stored in a cool, dry and ventilated place for use.

Embodiment 3

[0035] Accurately weigh 12 kg of zeolite, 0.3 kg of light rare earth salts, 30 kg of ferrous sulfate heptahydrate, 6 kg of magnesium sulfate, 35 kg of peat, 25 kg of caragana powder, and 12 kg of sweet straw grains; Machine crushed to 100 mesh. First mix zeolite and lanthanide light rare earth salts evenly, then add ferrous sulfate heptahydrate, magnesium sulfate, peat, caragana powder and sweet straw grains, and mix well. The homogeneously mixed product is sealed and packaged in polyethylene bags with more than double layers, and stored in a cool, dry and ventilated place for use. When in use, the ripening agent accounts for 1-2wt% of the organic fertilizer in use.

Abstract

The present invention relates to an organic fertilizer deodorization maturing agent and a preparation process thereof, wherein the organic fertilizer deodorization maturing agent comprises zeolite, rare earth, ferrous sulfate heptahydrate, magnesium sulfate, peat and caragana powder. According to the present invention, the organic fertilizer deodorization maturing agent has functions of catalysis, activation, degradation, transformation and fermentation, and has characteristics of short fertilizer forming time and rapid composting; the composting time can be saved by more than or equal to 2 / 5 compared with the general method, the organic fertilizer is composted after 4-6 days, the odor of the organic fertilizer can be effectively removed after 3-4 days, and the sweet and sour odor can be emitted; the organic fertilizer deodorization maturing agent has characteristics of simple production, readily available raw materials, low production cost and less consumption; and the organic fertilizer prepared from the organic fertilizer deodorization maturing agent has the organic matter content of more than or equal to 25%, the total NPK nutrient content of not less than 3.5%, the water water of less than 17%, and the pH value of 5.5-6.

Description

technical field [0001] The invention relates to an additive production process for decomposing organic fertilizers, in particular to an organic fertilizer deodorizing ripening agent and a preparation process thereof. Background technique [0002] Organic fertilizer is an ideal agricultural green fertilizer, which is made of natural organic matter through decomposing and fermenting. However, in organic fertilizers, some human and animal feces usually contain various pathogenic bacteria, viruses, parasites, etc., and some weeds contain various diseases and insect pests and seeds, etc. Organic fertilizers will damage the soil without harmless treatment or improper application. structure, polluting agricultural products and the environment; therefore, in crop production, especially in the production of green food in protected areas, organic fertilizer manure should be prohibited from being put on the ground, and it must be specially treated to make it harmless.
