Abstract

The present invention provides a production method of organic iron fertilizer. The present invention is made by inorganic iron of raw material components, carboxylic acid compounds of polyhydric phenol, auxiliary agents, and water for making complexation (chelating) reactions under a certain condition. The present invention has the characteristics of stable performance, lasting fertilizer effect, high biological effectiveness, etc. The present invention has obvious effects on the aspects of promoting plant growth, preventing and treating physiological diseases which are caused by the iron deficiency of plants.

Description

A kind of organic iron fertilizer
Technical field
The present invention relates to a kind of production method of chemical fertilizer, be meant a kind of production method of organic iron fertilizer especially.
Background technology
Iron is the necessary trace element of plant, and plant iron deficiency phenomenon usually takes place for China's alkalescence and calcareous soil, and using iron fertilizer is that crop yield improves, the key measure of quality improving.The little fertilizer of organic complex (chelating) can overcome and is easy to generate oxidation, antagonism, adverse consequences that precipitation caused after inorganic little fertilizer is used, it is stable to have fertilizer efficiency, easily by plant absorbing, utilization ratio advantages of higher, the main direction that to develop organic little fertilizer be little fertile industrial development.It is the core of the organic little fertilizer of exploitation that screening utilizes high performance cheap organic complex (chelating) agent.As Chinese patent application (application number: 93106928.9) disclose method, the Chinese patent application (application number: 200410029779.6) disclose the employing humic acids and produced organic chelated Medium Trace Element Fertilizer technology, Chinese patent application (application number: 00134366.1) disclose the method that adopts amino acid to make complexing agent production iron-amino acid chelate that utilizes citric acid to make complexing agent production organic complex compound trace element fertilizer as complexing agent.
Summary of the invention
The object of the present invention is to provide a kind of production method of organic iron fertilizer.It carries out complexing (chelating) reaction under certain condition by feed composition ferrous sulfate, polyphenol carboxylic acid cpd, auxiliary agent and water and makes, have that raw material is easy to get, production cost is low, characteristics such as stable performance, fertilizer efficiency are lasting, biological effectiveness height, promoting that effect is remarkable aspect the physiological disease that plant-growth, prevention and treatment plant iron deficiency cause.
The polyphenol carboxylic acid cpd is a kind of compound of valonex or valonex, two kinds of compounds of gallic acid among the present invention, and valonex is taken from industrial valonex, and auxiliary agent is sodium hydroxide and hydrogen peroxide.Each weight percentages of components is among the present invention: ferrous sulfate 30%~60%, and valonex 5%~20%, gallic acid 0~10%, auxiliary agent 1%~7.5%, Sodium dodecylbenzene sulfonate 1%~5%, water are surplus.
The present invention realizes by the following technical solutions: with weight percentages of components is that 5%~20% valonex is put into reactor, it with weight percentages of components 10%~40% water dissolution, regulate about pH7.5 with sodium hydroxide again, the adding weight percentages of components is 0.5%~6% hydrogen peroxide, reacts 0.5~6 hour down at 20~85 ℃.Then, adding weight percentages of components in reactor is 0~10% gallic acid.Be that 30%~60% ferrous sulfate and excess water add in the reactor again with weight percentages of components, under 60~110 ℃, carry out complexing (chelating) reaction in 0.5~6 hour, treat complex reaction technology finish after with 100~120 mesh sieve filtering solutions.Last in the filtering solution adding weight percentages of components be 1%~5% Sodium dodecylbenzene sulfonate and stir and can obtain the finished product.
The present invention is further illustrated below in conjunction with embodiment.
Embodiment 1:
With weight percentages of components is that 15% valonex is put into reactor, is 20% water dissolution with weight percentages of components, regulates about pH7.5 with sodium hydroxide again, adds weight percentages of components and be 3% hydrogen peroxide, 80 ℃ of reactions 1.5 hours down.Then, adding weight percentages of components in reactor is 2% gallic acid.Be that 50% ferrous sulfate and excess water add in the reactor again with weight percentages of components, under 90 ℃, carry out complex reaction in 1 hour, treat this technology finish after with 100 mesh sieve filtering solutions.Last in the filtered liquid adding weight percentages of components be 2% Sodium dodecylbenzene sulfonate and stir and can obtain the finished product.
Embodiment 2:
Schedule of operation is identical with embodiment 1 during preparation.Just in the scope of schedule of operation defined of the present invention, raw material types, quantity and solvent temperature, reaction times are changed, still be prepared into organic iron fertilizer of the present invention equally.

Claims (2)

1, a kind of organic iron fertilizer is characterized in that each weight percentages of components is: ferrous sulfate 30%~60%, and valonex 5%~20%, gallic acid 0~10%, auxiliary agent 1%~7.5%, Sodium dodecylbenzene sulfonate 1%~5%, water are surplus; Wherein auxiliary agent is sodium hydroxide and hydrogen peroxide.
2., according to the production method of the described a kind of organic iron fertilizer of claim 1, it is characterized in that with weight percentages of components being that 5%~20% valonex is put into reactor, it with weight percentages of components 10%~40% water dissolution, regulate about pH7.5 with sodium hydroxide again, the adding weight percentages of components is 0.5%~6% hydrogen peroxide, reacts 0.5~6 hour down at 20~85 ℃; Then, adding weight percentages of components in reactor is 0~10% gallic acid; Be that 30%~60% ferrous sulfate and excess water add in the reactor again with weight percentages of components, under 60~110 ℃, carry out complex reaction in 0.5~6 hour, treat complex reaction technology finish after with 100~120 mesh sieve filtering solutions, last in the filtering solution adding weight percentages of components be 1%~5% Sodium dodecylbenzene sulfonate and stir and can obtain the finished product.
