Embodiment 1

[0017] Each component is weighed by the formula of Example 1 in Table 1, and other components except zinc sulfate monohydrate are dissolved in water to be mixed with the solution that concentration is 20wt%, after the gained solution mixes with zinc sulfate monohydrate, press present There are conventional methods for granulation and drying at 80-90°C to obtain the water-soluble integrated zinc sulfate monohydrate granular fertilizer.

Embodiment 2

[0019] Take each component by the formula of embodiment 2 in table 1, and other components except zinc sulfate monohydrate are dissolved in water and be mixed with the solution that concentration is 25wt%, after the gained solution mixes with zinc sulfate monohydrate, press present There are conventional methods for granulation and drying at 80-90°C to obtain the water-soluble integrated zinc sulfate monohydrate granular fertilizer.

Embodiment 3

[0021] Each component is weighed by the formula of Example 3 in Table 1, and other components except zinc sulfate monohydrate are dissolved in water and are mixed with the solution that concentration is 30wt%, after the gained solution mixes with zinc sulfate monohydrate, press present There are conventional methods for granulation and drying at 95-105°C to obtain the water-soluble integrated zinc sulfate monohydrate granular fertilizer.

Abstract

The invention discloses a water-soluble integrated zinc sulfate monohydrate granular fertilizer and a preparation method thereof. The water-soluble integrated zinc sulfate monohydrate granular fertilizer is prepared from the following components in percentage by mass: 0.1 to 6.0 percent of a chelating agent, 0.2 to 0.5 percent of phosphoric acid, 0.2 to 0.5 percent of monopotassium phosphate, 0 to3.0 percent of an adhesive, 1.0 to 5.0 percent of urea and the balance being zinc sulfate monohydrate. The zinc sulfate monohydrate, the chelating agent, the phosphoric acid and the monopotassium phosphate are formulated and chelated, so that on one hand, zinc in the obtained zinc fertilizer is in an organic chelated state, the water solubility is good, and the zinc fertilizer is easier to absorbby soil, so that the fertilizer efficiency of the obtained zinc fertilizer is greatly improved; and on the other hand, the antagonism of zinc and other elements is overcome, the blending property andthe buffering property are improved, the zinc fertilizer and macroelements are applied at the same time, and the zinc fertilizer is more suitable for water and fertilizer integration and modern agriculture.
