preparation example Construction

[0026] The invention provides a preparation method of the above-mentioned trace element foliage fertilizer, comprising the steps of:

[0027] (1) Potassium sulfite, boron fertilizer and molybdenum fertilizer are pulverized respectively to obtain potassium sulfite powder, boron fertilizer powder and molybdenum fertilizer powder;

[0028] (2) drying the potassium phosphite powder, boron fertilizer powder and molybdenum fertilizer powder at 40-60° C. for 1-2 h respectively to obtain potassium phosphite dry powder, boron fertilizer dry powder and molybdenum fertilizer dry powder;

[0029] (3) Mix the potassium phosphite dry powder, boron fertilizer dry powder, molybdenum fertilizer dry powder, iron fertilizer, manganese fertilizer, zinc fertilizer and copper fertilizer and stir for 20-30 minutes to obtain trace element foliage fertilizer.

[0030] In the invention, the potassium sulfite, boron fertilizer and molybdenum fertilizer are first pulverized respectively to obtain potassi...

Embodiment 1

[0037]A trace element foliar fertilizer with the function of preventing and controlling diseases, adopting multi-component compound production technology, is composed of the following ingredients: potassium dihydrogen phosphite 13.3%, dipotassium hydrogen phosphite 6.7%, EDTA-Fe 2.0%, ferrous sulfate Ammonium 4%, EDTA-Mn3.0%, Manganese Sulfate 5.0%, Zinc Sulfate Monohydrate 18%, EDTA-Zn 9.35%, Boric Acid 20%, Borax 17%, EDTA-Cu1.0%, Ammonium Molybdate 0.15%, Magnesium sulfate 0.3%, sodium lauryl sulfate 0.2%.

[0038] The production process is as follows: Potassium phosphite, boric acid, borax, and ammonium molybdate are pulverized and dried, and put into the weighing hopper in proportion to other raw materials, stirred by a mixer for 20-30 minutes, fully mixed, and then packed by a semi-automatic packing machine. Put it in a bag of corresponding specification and seal it.

Embodiment 2

[0040] A trace element foliar fertilizer with the function of preventing and controlling diseases, adopts multi-component compound production process, and is composed of the following ingredients: potassium dihydrogen phosphite 13.3%, dipotassium hydrogen phosphite 6.7%, ferrous sulfate 25%, manganese sulfate 3.35% %, zinc sulfate heptahydrate 20%, sodium octaborate tetrahydrate 20%, boric acid 10%, copper sulfate 1.0%, ammonium molybdate 0.15%, sodium tripolyphosphate 0.5%.

[0041] Production technology is with " embodiment 1 ".

Abstract

The invention provides a trace element foliar fertilizer, and a preparation method and an application thereof, and belongs to the technical field of agricultural fertilizer processing and production.The trace element foliar fertilizer comprises, by mass, 18-22% of potassium phosphite, 5-28.5% of an iron fertilizer, 2-18% of a manganese fertilizer, 15-33% of a zinc fertilizer, 10-37% of a boron fertilizer, 1-5% of a copper fertilizer and 0.1-0.2% of a molybdenum fertilizer. The application of the trace element foliar fertilizer to agricultural production significantly increases the yield of crops; and the trace element foliar fertilizer provided by the invention can significantly reduce the disease incidence and the incidence index of plants, and has a remarkable disease control effect.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer processing and production, in particular to a trace element foliar fertilizer and its preparation method and application. Background technique [0002] Medicinal fertilizer is a new type of ecological compound fertilizer formed by mixing pesticides and fertilizers in a certain proportion, and stabilizing the fertilizers and pesticides in a specific compound system through a certain process technology. Generally, fertilizers are used as the carrier of pesticides. For the sustainable development of contemporary agriculture, medicinal fertilizer is a new attempt for modern agriculture supported and driven by powerful technology. Medicinal fertilizer can combine two operation steps in the field into one, which not only saves labor, but also reduces time and energy consumption. However, most fertilizers cannot be shared with pesticides, and they are prone to reactions to produce insolu...
