Problems solved by technology

[0002] Trace elements play an extremely important role in plant growth. At present, there is some research on compound micro-fertilizers containing trace elements needed for plant growth, March 5, 2008 The invention patent with the publication number CN101134688A discloses a kind of all-element chelating high-efficiency micro-fertilizer and its manufacturing method. It adopts chelating agent to carry out chelating reaction with various trace elements, and adds magnesium oxide to adjust the pH value. However, because it contains The content of magnesium and copper is high, which is not suitable for some areas, especially the situation where most of the calcium and magnesium in the alluvial plain of the Yellow River exceed the standard, and the sulfur in the soil exceeds the standard. At present, there is no research on the formula of chelated compound trace element fertilizer for vegetables.

Abstract

The invention discloses a chelated compound trace element fertilizer and a preparation method thereof. The chelated compound trace element fertilizer comprises the following components: EDTA (ethylene diamine tetraacetic acid) chelated copper, EDTA chelated zinc, EDTA chelated iron, EDTA chelated manganese, borax decahydrate and ammonium molybdate. The preparation method comprises the steps of preparing EDTA chelated copper, EDTA chelated zinc, EDTA chelated iron and EDTA chelated manganese; purchasing borax decahydrate and ammonium molybdate; mixing the raw materials, drying, grinding and packaging to obtain a finished product. The prepared trace element fertilizer can be sprayed or flushed, and has a good effect on improving the symptoms such as small leaves, yellow leaves, undergrowth and the like of vegetables caused by deficiency of trace elements.

Description

technical field [0001] The invention relates to a trace element fertilizer and a preparation method thereof, in particular to a chelated compound trace element fertilizer and a preparation method thereof. Background technique [0002] Trace elements play an extremely important role in plant growth. At present, there is some research on compound micro-fertilizers containing trace elements needed for plant growth. On March 5, 2008, the invention patent with the publication number of CN101134688A disclosed a full-element chelate Combined high-efficiency micro-fertilizer and its manufacturing method are to use chelating agent to carry out chelating reaction with various trace elements, and add magnesium oxide to adjust pH value, but because it contains magnesium element and copper content is high, it is not suitable for some areas, especially Most of the calcium and magnesium in the alluvial plain of the Yellow River exceed the standard, and the sulfur in the soil exceeds the s...
