Embodiment Construction

[0029] A compound fertilizer preparation process, comprising the following steps:

[0030] S1: Mix human and animal manure, straw, sawdust, and grain bran, and then seal and ferment to form a fermentation material;

[0031] S2: add ammonium dihydrogen phosphate, urea and potassium sulfate to the sprinkling device;

[0032] S3: Sprinkle ammonium dihydrogen phosphate, urea and potassium sulfate on the fermented material through a sprinkling device, and continuously turn the fermented material during the sprinkling process;

[0033] S4: The ammonium dihydrogen phosphate, urea and potassium sulfate are again stirred together with the fermentation mass.

[0034] The sealed fermentation time in the S1 was 21 days.

[0035] Described human and animal excrement is chicken excrement and human excrement, and the weight ratio of chicken excrement and human excrement is 4:6.

[0036] like Figure 5-6 As shown, this example can achieve the effect that ammonium dihydrogen phosphate, ure...

Abstract

The invention relates to the field of compound fertilizer preparation, in particular to a compound fertilizer and a preparation process thereof. The process comprises the following steps: S1, mixing the human and animal excreta, the straw, the sawdust and the cavings, and performing sealed fermentation to form a fermented material; s2, ammonium dihydrogen phosphate, urea and potassium sulfate are mixed and then added into a material spraying device; s3, ammonium dihydrogen phosphate, urea and potassium sulfate are sprayed on the fermentation material through a spraying device, and the fermentation material is continuously turned over in the spraying process; and S4, stirring the ammonium dihydrogen phosphate, the urea, the potassium sulfate and the fermentation material. The sealed fermentation time in the step S1 is 21 days. The human and animal manure is chicken manure and human manure, and the weight ratio of the chicken manure to the human manure is 4: 6. Ammonium dihydrogen phosphate, urea and potassium sulfate can be sprayed on the fermentation material through the material spraying device, so that the ammonium dihydrogen phosphate, the urea and the potassium sulfate are more easily mixed into human and animal excreta, straws, sawdust and cavings.

Description

technical field [0001] The invention relates to the field of compound fertilizer preparation, in particular to a compound fertilizer and a preparation process thereof. Background technique [0002] Compound fertilizers are chemical fertilizers containing two or more nutrient elements, which play an important role in balancing fertilization, improving fertilizer utilization, and promoting high crop yields. Compound fertilizers have the advantages of few auxiliary components and good physical properties. However, in the preparation of compound fertilizer, when ammonium dihydrogen phosphate, urea and potassium sulfate are directly mixed with human and animal manure, straw, sawdust and grain bran, ammonium dihydrogen phosphate, urea and potassium sulfate are easily aggregated and agglomerated, and are not easily mixed into human and animal manure, In straw, sawdust and chaff. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the prior art, the presen...
