Abstract

The invention discloses a preparation method for efficient compound fertilizer. The efficient compound fertilizer is prepared by fermenting a mixture of pig manure and chicken manure, drying the fermented mixture, adding an inorganic fertilizer into the dried mixture, and carrying out pelletization, wherein in the fermentation process, various additives are added for controlling the pH value to avoid loss of the fertilizer; the efficient compound fertilizer has effects of moisture and fertilizer retention and drought tolerance, is convenient to transport and use, and serves as an excellent compound fertilizer with high quality.

Description

A kind of preparation method of efficient compound fertilizer

Technical field

The present invention relates to fertilizer field, particularly relate to a kind of preparation method of efficient compound fertilizer.

Background technology

" Organic farming " refers to an organic fertilizer in agriculture production, not to fertilize, or many organic fertilizers, Shaoshi chemical fertilizer, to recover the crumb structure of soil, builds up fertility." ecological agriculture " emphasizes that, based on organic fertilizer in crop production, input and output reaches balance, free from environmental pollution.For making agriculture production carry out according to natural law continuously, Development and Production has become important development direction from now on without the agricultural-food that chemical noxious material pollutes.Fertilizer use the content that can increase the soil organism, organic matter is the matrix of soil microbial activity, soil ulmin can be produced through microbial decomposition, this humic mass-energy promotes the formation of soil aggregate, thus improve physical and chemical performance and the biological property of soil, strengthen the shock-absorbing capacity of soil, reduce the loss of soil to the fixing of N, P, K and soil, fertilizer has wide market outlook.

Fertilizer of the prior art adopts animal excrement or plant to make through fermentation mostly, but in the process of fermentation, easily causes the loss of a large amount of compositions, as compositions such as ammonia nitrogens.

Summary of the invention

The object of the invention is, in order to solve the problem, to provide a kind of preparation method of efficient compound fertilizer.

For achieving the above object, the method that the present invention adopts is: a kind of preparation method of efficient compound fertilizer, comprises following step:

(1), the mixture of pig manure, chicken manure is smashed in rear feeding plastic greenhouse fermentation installation and ferment;

(2), in fermentation vat, add stalk again to ferment;

(3), fermentation for some time after, add wherein saleratus regulate pH value, make its pH value control between 7-8;

(4), by the fertilizer fermented send in drying plant and carry out drying, make its water content be reduced to less than 10%;

(5), by mixed fertilizer cool, after pulverize, be ground into 60-80 object fineness;

(6), mix after adding urea in mixed fertilizer;

(7), the fertilizer mixed is sent in tablets press, add tackiness agent granulation, pack after cooling.

Beneficial effect:

Efficient compound fertilizer of the present invention is that fowl and animal excrement is after fermentative processing and drying and processing, add that the inorganic fertilizers such as urea make through granulation, by adding the additive of each composition in the process of fermentation, control the loss that pH value prevents fertilizer, and transport easy to use, be a kind of compound manure of very high-quality.

Embodiment

Embodiment 1:

A preparation method for efficient compound fertilizer, comprises following step:

(1), the mixture of pig manure, chicken manure is smashed in rear feeding plastic greenhouse fermentation installation and ferment;

(2), in fermentation vat, add stalk again to ferment;

(3), fermentation for some time after, add wherein saleratus regulate pH value, make its pH value control between 7-8;

(4), by the fertilizer fermented send in drying plant and carry out drying, make its water content be reduced to less than 10%;

(5), by mixed fertilizer cool, after pulverize, be ground into 60-80 object fineness;

(6), mix after adding urea in mixed fertilizer;

(7), the fertilizer mixed is sent in tablets press, add tackiness agent granulation, pack after cooling.

Beneficial effect:

Efficient compound fertilizer of the present invention is that fowl and animal excrement is after fermentative processing and drying and processing, add that the inorganic fertilizers such as urea make through granulation, by adding the additive of each composition in the process of fermentation, control the loss that pH value prevents fertilizer, and transport easy to use, be a kind of compound manure of very high-quality.
