Embodiment 1

[0040] (1) Take straw, mix and crush the straw to obtain a mixture A20kg;

[0041] (2) Add animal manure 40kg in the mixture A in step (1), mix and stir to obtain mixture B60kg;

[0042] (3) Ferment the stirred mixture B at 50 degrees Celsius and decompose. The present invention adopts strip-stack fermentation, and the starter used contains yeast, actinomycetes, bacteria, filamentous fungi and other microbial flora, the amount of starter is about 0.1kg, and the fermentation period is 7 days. It is an exothermic process. Therefore, in order to prevent the activity of the starter from being affected by the high temperature of the raw materials, a compost turner is used to regularly turn the compost, which can not only control the temperature within the required range, but also mix all kinds of raw materials evenly.

[0043] (4) Dry the mixture B through fermentation and decomposing in step (3), pulverize, and obtain organic matter as 50kg. After the fermentation is completed, ...

Embodiment 2

[0048] (1) Take straw, mix and crush the straw to obtain a mixture A30kg;

[0049] (2) Add animal excrement 43kg in the mixture A in step (1), mix and stir to obtain mixture B73kg;

[0050] (3) Ferment the stirred mixture B at 60 degrees Celsius and decompose. The process is the same as described in Example 1.

[0051] (4) The fermented and decomposed mixture B in step (3) is dried and pulverized to obtain 63 kg of organic matter, and about 10 kg of moisture is removed during the drying process. After the drying is completed, the semi-finished raw materials are crushed to prevent agglomeration and affect the quality of the organic fertilizer.

[0052] (5) Take 8kg of urea, 7kg of monoammonium phosphate, 14kg of potassium magnesium sulfate, and 8kg of silicon-calcium fertilizer to make a total of 37kg of chemical fertilizers;

[0053] 6. Add the chemical fertilizer prepared in the step 5 to the organic fertilizer, mix and stir to obtain a total of 100kg of mixture C;

[005...

Embodiment 3

[0056] (1) Take straw, mix and crush the straw to obtain a mixture A30kg;

[0057] (2) Add animal excrement 55kg in the mixture A in step (1), mix and stir to obtain mixture B85kg;

[0058] (3) Ferment the stirred mixture B at 60 degrees Celsius and decompose. The process is the same as described in Example 1.

[0059] (4) Dry the fermented and decomposed mixture B in step (3), pulverize, and obtain 75 kg of organic matter, and about 10 kg of moisture is removed during the drying process. After the drying is completed, the semi-finished raw materials are crushed to prevent agglomeration and affect the quality of the organic fertilizer.

[0060] (5) Take 6kg of urea, 4kg of monoammonium phosphate, 10kg of potassium magnesium sulfate, and 5kg of silicon-calcium fertilizer to make 25kg of chemical fertilizer;

[0061] 6. Add the chemical fertilizer prepared in the step 5 to the organic fertilizer, mix and stir to obtain a total of 100kg of mixture C;

[0062] (7) Grinding, st...

Abstract

The invention relates to the field of fertilizer, in particular to a combined fertilizer and a preparation method of the combined fertilizer. The combined fertilizer is made by mixing an organic fertilizer with the mass ratio being 50-75wt% and a chemical fertilizer with the mass ratio being 25-50wt%. The chemical fertilizer comprises urea, monoammonium phosphate, potassium magnesium sulfate and a silicon calcium fertilizer. The organic fertilizer is made by steps of mixing crushed haulm and straw with animal feces and agitating and fermenting the mixture at high temperature. Chemical fertilizer is added into the organic fertilizer and the mixture is agitated to prepare the particle combined fertilizer. The combined fertilizer provided by the invention is beneficial for yield increase of plants, and is in particular suitable for fruit tree plants.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a combined fertilizer and a preparation method thereof. Background technique [0002] In recent years, under the correct leadership of national policies and the continuous improvement of people's requirements for food, the use of organic fertilizers has continued to increase, so the production of organic fertilizers has also received increasing attention. Since most of the raw materials for the production of organic fertilizers are agricultural Waste, poultry manure, waste from food factories, etc., many of these raw materials are sources of pollution, so the production of organic fertilizers has an environmental protection effect. The application of organic fertilizer not only improves the soil and activates the beneficial microorganisms in the soil, but more importantly, saves energy and reduces environmental pollution. The use of some bio-organic fertilizers can provide the soil wi...
