Embodiment 1

[0018] Embodiment 1, a kind of production method of potassium fulvic acid and EDTA chelated state composite micro-fertilizer, is characterized in that: comprise the following steps: A. EDTA disodium 223g sodium hydroxide 40g is added in 1000g water, Mix well, then add metal alkali: 0.1mol each of calcium hydroxide, iron hydroxide, manganese hydroxide, copper hydroxide, zinc hydroxide, and magnesium hydroxide, and react for 2 to 3 hours at 50-80°C to form EDTA chelated calcium, iron, manganese, copper, zinc, magnesium,

[0019] B. Add 20g of potassium borate and 5g of potassium molybdate to the product of step A, and stir and mix to obtain an intermediate liquid product

[0020] C. Add 250 g of potassium fulvic acid to the product of step B and mix well to obtain the finished chelated trace element fertilizer.

Abstract

The invention discloses a production method for a fulvic acid potassium and EDTA chelating state microelement complex fertilizer, belongs to methods for manufacturing fertilizer, and particularly relates to a mixture of one or more fertilizers and un-specific fertilizer efficiency components. The production method comprises the steps as follows: ethylenediamine tetraacetic acid disodium and sodium hydroxide are added firstly; then various metal alkalis are added to generate EDTA chelated calcium, iron, manganese, copper, zinc and magnesium; potassium borate potassium molybdate and fulvic acid potassium are added, so that the finished product chelating state microelement complex fertilizer is obtained. The invention provides a novel production method for the fulvic acid potassium and EDTA chelating state microelement complex fertilizer, according to the method, EDTA disodium and metal ions are prepared according to the proportion of 1:1, acid-base reaction is performed, the product is an ionic compound formed through an ionic bond, the ionic bond is more stable than a coordinate bond, the liquid fertilizer prepared through the method has a stable space structure, can effectively prevent the metal ions to form insoluble substances with acid radical ions in soil, and has the favorable effects of yield increase and agricultural product quality improvement.

Description

technical field [0001] The invention belongs to a fertilizer preparation method, in particular to a mixture of one or more fertilizers and components without special fertilizer effects. Background technique [0002] In recent years, the use of potassium fulvic acid to prepare chelated fertilizers has begun to be taken seriously, and various scientific research and production units have carried out a large number of experimental studies. As Chinese patent 201010503305.6 discloses a preparation method of potassium fulvic acid chelated fertilizers, it consists of the following parts by weight Made of raw materials, chelating agent 18, heavy calcium 18, urea 20, ammonium sulfate 12 and ammonium nitrate 8, wherein the chelating agent is made of copper sulfate, ferrous sulfate, zinc sulfate, manganese sulfate, boric acid, potassium fulvate, urea, Made of EDTA etc. However, this method is formed through coordination bonds, and the spatial structure is not stable enough, and metal ...
