Embodiment 1

[0029] An organic-inorganic slow-release compound fertilizer is made of the following raw materials in weight percentage:

[0030]

[0031] Its preparation method steps are as follows:

[0032] First weigh 240kg of potassium sulfate, 270kg of humic acid, 240kg of monoammonium phosphate, 55kg of thiamine, 250kg of urea, and 35kg of slow-release agent; then sprinkle 270kg of humic acid evenly on other raw materials and put them in the crusher for Crushing and mixing, the crushing effect is 105 mesh; then put the uniformly mixed raw materials into the granulator for granulation, the granulation steam pressure is 0.7mp, the granulation temperature is 39°C, and the granulation rate after granulation is 85 %; then put the pellets into the dryer for drying, the drying temperature is: the inlet temperature is 135°C, and the outlet temperature is 60°C; then put the dried pellets into the cooler to cool, and the The final granules are sub-sieved twice to improve the uniformity; then...

Abstract

The invention provides an organic and inorganic slow-release compound fertilizer and a preparation method thereof, and relates to the technical field of chemical fertilizers. The organic and inorganic slow-release compound fertilizer comprises potassium sulfate, humic acid, monoammonium phosphate, thiamine, urea and a slow-release agent. The preparation method comprises the following steps: preparing materials, batching materials, mixing, granulating, drying, cooling, sizing, enveloping membranes, packing and entering warehouse. The chemical fertilizer provided by the invention can enable active ingredients to be released slowly and gradually, the fertilizer consumption is reduced, the utilization rate is improved, the construction is convenient, the labor is saved, the safety is achieved, the soil environment is improved, and the soil looseness degree is improved.

Description

Technical field: [0001] The invention relates to the technical field of chemical fertilizers, in particular to an organic-inorganic slow-release compound fertilizer and a preparation method thereof. Background technique: [0002] Chemical fertilizers are widely used in agricultural production. Chemical fertilizers are easily soluble in water and will work immediately after fertilization and be absorbed by crops in a short period of time. Therefore, in each stage of crop growth, it is necessary to apply various fertilizers, such as nitrogen fertilizer, potassium fertilizer, phosphorus fertilizer, ammonium fertilizer, etc. These fertilizers with different functions cannot be applied at one time in advance. In addition, the amount of fertilization should be appropriate, not too much, otherwise it will be detrimental to the growth of crops. In this way, for crops, it will cause uneven fertilizer application, that is, enough fertilizer in the early stage of fertilization, which ...
