Problems solved by technology

Although people have made some new breakthroughs in the research and development of organic iron fertilizers, due to the lack of targeted organic iron fertilizer formulas with reasonable proportions, the existing organic iron fertilizers still have problems such as single species, incomplete efficacy, and poor use effects.

Embodiment 1

[0010] The humic acid that the component weight percent is 10% is put into reactor, adds the water that component weight percent is 35% and dissolves; Then in reactor, add the sweet potato starch that component weight percent is 5%, at 80 Stir for 0.2 hours at °C; then add polyacrylamide with a component weight percentage of 49% to the reactor; finally add 0.5% hydroxyethyl methacrylate, 0.5% The ammonium persulfate was reacted at 100°C for 2 hours, and the reaction product was solidified and dried, and then pulverized to obtain a water-retaining substance for future use. Put 25% citric acid by weight into the reactor, dissolve it in water with 20% by weight, add hydrogen peroxide with 3% by weight, and react at 80°C for 0.2 hours; then 5% mercaptoacetic acid was added to the reaction kettle by weight percentage, and stirred for 0.2 hours; then 46% ferrous sulfate and 1% urea were added to the reaction kettle by weight percentage of the composition, and carried out at 100°C fo...

Embodiment 2

[0012] The operating procedure was the same as in Example 1 during preparation. Just change the type of raw material, raw material quantity and temperature, stirring time and reaction time within the scope specified by the operation procedure of the present invention, and still prepare a kind of organic iron fertilizer with water retention effect of the present invention in the same way.

Abstract

The invention provides a preparation method for organic iron fertilizer with a water retention function. The organic iron fertilizer is prepared by effectively blending substances of which the raw material ingredients have water retention, substances containing organic iron elements, attapulgite powder, paratoluenesulfonic acid sodium salt, vermiculite and perlite under a certain condition. The organic iron fertilizer has an obvious effect on enhancing soil water holding capacity, preventing and treatingcuring physiological diseases caused by iron deficiency of crops and accelerating crops togrow and develop.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a method for preparing an organic iron fertilizer with water retention function. Background technique [0002] Low- and medium-yield fields in my country account for about 70% of the total cultivated land area. Due to the long-term excessive application of nitrogen, phosphorus, potassium and other large-scale element fertilizers in some high-yield fields, the soil quality has deteriorated and the yield increase rate has continued to decline. Trace elements play the same important physiological role as macronutrients in ensuring the normal growth and development of crops. The lack of soil trace elements directly affects the normal growth and development of crops, resulting in low and unstable yields and poor quality. Trace element fertilizer is an important substance that supplies essential nutrients for crops, improves soil properties, and improves soil fertility. Targeted application of trace el...
