Embodiment 1

[0038] figure 1 Shown is the preparation method of the chelate fertilizer according to one embodiment of the present invention. According to this method, first enter step S1100, mix 30 parts of sodium humate, 30 parts of ferrous sulfate heptahydrate, 8 parts of zinc sulfate monohydrate, 8 parts of manganese sulfate and 2 parts of boric acid, wherein the sodium humate It is prepared according to the following steps: Concentrate the sodium humate solution with a mass percentage concentration of 6% at 98 degrees, dry the concentrated sodium humate solution at 100 degrees, and dry the dried humic acid The sodium solid is crushed into 200-mesh particles; the uniformly mixed mixture is entered into step S1200 for chelation, and the mixture is pulverized for stirring and chelation. So far step S1200 is completed, and the preparation of chelate fertilizer is completed.

Embodiment 2

[0040] figure 1 Shown is the preparation method of the chelate fertilizer according to one embodiment of the present invention. According to this method, first enter step S1100, mix 40 parts of sodium humate, 40 parts of ferrous sulfate heptahydrate, 12 parts of zinc sulfate monohydrate, 12 parts of manganese sulfate and 4 parts of boric acid, wherein the sodium humate It is prepared according to the following steps: Concentrate the sodium humate solution with a mass percentage concentration of 8% at 102 degrees, dry the concentrated sodium humate solution at 110 degrees, and dry the dried humic acid Sodium acid solids are crushed into 250-mesh particles; the uniformly mixed mixture is entered into step S1200 for chelation, and the mixture is pulverized for stirring and chelation. So far step S1200 is completed, and the preparation of chelate fertilizer is completed.

Embodiment 3

[0042] figure 1 Shown is the preparation method of the chelate fertilizer according to one embodiment of the present invention. According to this method, first enter step S1100, mix 36 parts of sodium humate, 35 parts of ferrous sulfate heptahydrate, 10 parts of zinc sulfate monohydrate, 10 parts of manganese sulfate and 3 parts of boric acid, wherein the sodium humate It is prepared according to the following steps: concentrate the sodium humate solution with a mass percentage concentration of 7% at 100 degrees, dry the concentrated sodium humate solution at 105 degrees, and dry the dried humic acid Sodium acid solids are crushed into 230-mesh particles; the uniformly mixed mixture is entered into step S1200 for chelation, and the mixture is pulverized for stirring and chelation. So far step S1200 is completed, and the preparation of chelate fertilizer is completed.

Abstract

The invention discloses a chelated fertilizer which comprises the following raw materials in parts by weight: 30-40 parts of sodium humate, 30-40 parts of ferrous sulfate heptahydrate, 8-12 parts of zinc sulphate monohydrate, 8-12 parts of manganese sulfate and 2-4 parts of boracic acid. The chelated fertilizer is prepared through the following steps of: (1) mixing: weighing the sodium humate, the ferrous sulfate heptahydrate, the zinc sulphate monohydrate, the manganese sulfate and the boracic acid, and uniformly mixing; and (2) chelating: smashing the mixture, and then stirring and chelating. The chelated fertilizer prepared according to the method can be used for supplementing sufficient trace elements to soil and is enhanced in fertilizer utilization ratio and difficult to solidify the soil.

Description

technical field [0001] The invention relates to a chelated fertilizer and a preparation method thereof, in particular to a humic acid chelated fertilizer and a preparation method thereof. Background technique [0002] Due to the large-scale use of chemical fertilizers in the prior art, the imbalance between trace elements is becoming more and more serious, which leads to a decline in the utilization rate of fertilizers, and the solidification of soil caused by a large amount of chemical fertilizers is becoming more and more serious. [0003] Therefore, there is a need to provide a fertilizer that supplements micronutrients and prevents soil solidification. Contents of the invention [0004] For this reason, the present invention proposes a kind of chelate fertilizer and its preparation method that can solve the above-mentioned problem at least partly solve the above-mentioned problem. [0005] According to one aspect of the present invention, a kind of chelate fertilizer ...
