Problems solved by technology

[0003] However, the utilization rate of chemical fertilizers in the prior art is not high, which not only causes a serious waste of resources, but also destroys the structure of the soil, leads to the decline of humus and upper soil, kills organic organisms in the soil, and destroys the organic matter in the soil. Ecological balance and the imbalance and loss of organic matter

preparation example Construction

[0027] The embodiment of the present invention also provides a kind of preparation method of above-mentioned nitrofulvic acid compound fertilizer, it comprises:

[0028] The molten ammonium nitrate, molten phosphate fertilizer, molten potassium fertilizer, molten ammonium nitrogen fertilizer, fulvic acid salt and filler are mixed and granulated.

[0029] Further, during the mixing process, the temperature is maintained at 130-180°C. In this temperature range, the fluidity of each raw material can be guaranteed, which is conducive to uniform mixing. When mixing, a stirrer can be used for stirring, the stirring speed is 500-1000 rpm, and the stirring time is 10-60 min.

[0030] Further, in the actual production process, the molten ammonium nitrate can be mixed with molten potassium fertilizer and filler to obtain the first mixture; then the first mixture can be mixed with phosphate fertilizer and ammonium nitrogen fertilizer to obtain the second mixture material; then the seco...

Abstract

The invention discloses a nitro fulvic acid compound fertilizer, and relates to the technical field of fertilizers. Fulvate is mixed with a nitrogen fertilizer, a phosphate fertilizer and a potash fertilizer according to a certain proportion for use, and due to the fact that the fulvate contains a great number of active functional groups and is relatively high in complexation, chelation and surface adsorption capacity, and the fulvate can be in complexation with ammoniacal nitrogen, so that the loss of the ammoniacal nitrogen is reduced; the displacement distance of phosphorus inside soil alsocan be increased, and the fixation of soil for water-soluble phosphorus is inhibited, so that ineffective phosphorus is converted into effective phosphorous, and the adsorption of a root system for phosphorus is promoted; and simultaneously, fulvic acid can adsorb and store potassium ions, the content of the effective phosphorous is improved, and particularly, the synergism for the potash fertilizer is obvious. The nitro fulvic acid compound fertilizer can effectively reduce the loss of the chemical fertilizer, the utilization rate of the chemical fertilizer is increased, and the pollution and damage to the soil are reduced. A preparation method of the nitro fulvic acid compound fertilizer is simple in operation and not high in equipment requirement, and large-scale industrial productionof the nitro fulvic acid compound fertilizer can be realized.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nitrofulvic acid compound fertilizer and a preparation method thereof. Background technique [0002] Chemical fertilizers are referred to as chemical fertilizers. Fertilizers made by chemical and (or) physical methods containing one or several nutrient elements needed for the growth of crops. Also known as inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc. Compared with traditional organic fertilizers, chemical fertilizers have the following characteristics: their ingredients are simple and their nutrient content is high; their fertilizer effects are fast and fertile; some fertilizers have acid-base reactions; they generally do not contain organic matter and have no effect on soil improvement and fertilization. [0003] However, the utilization rate of chemical fertilizers in ...
