Embodiment 1

[0010] The sodium alginate that the component weight percentage is 10% is put into the reactor, and the water that adds the component weight percentage is 31% is dissolved; Add the sweet potato starch that the component weight percentage is 5% in the reactor then, at 80 Stir at ℃ for 0.2 hours; then add polyacrylamide with a component weight percentage of 52% to the reactor; finally add 1% hydroxyethyl acrylate and 1% potassium persulfate to the reactor , react at 100° C. for 1.5 hours, and the reaction product is solidified and dried, and then pulverized to obtain a water-retaining material for use. The tartaric acid with a component weight percentage of 25% is put into the reactor, dissolved in water with a component weight percentage of 20%, and hydrogen peroxide with a component weight percentage of 3% is added, and reacted at 80°C for 0.5 hours; Add citric acid with a component weight percentage of 5% in the reactor, and stir for 0.2 hours; then add manganese sulfate and ...

Embodiment 2

[0012] The operating procedure was the same as in Example 1 during preparation. Only within the range specified by the operation procedure of the present invention, the raw material type, raw material quantity and temperature, stirring time and reaction time are changed, and a kind of organic manganese fertilizer with water retention effect of the present invention is still prepared in the same way.

Abstract

The invention provides a preparation method of an organic manganese fertilizer with a water preservation retention effect. The organic manganese fertilizer is prepared from raw material ingredients ofwater preservation retention substances, substances containing organic manganese elements, attapulgite powder, sodium p-toluenesulfonate, vermiculite and perlite through the effective compounding andmixing under a certain condition. The effects in aspects of enhancing soil water holding performance, preventing and controlling physiological diseases caused bydue to manganese lack inof crops, andpromoting the crop growth and development are obvious.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a method for preparing an organic manganese fertilizer with water retention effect. Background technique [0002] 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. The application of trace element fertilizers is an important measure to increase crop yield. The application of trace element fertilizers to different crops in different regions has a very obvious effect of increasing production, generally reaching 5% to 30%. The application of trace element fertilizers can not only increase the yield of crops, but also improve ...
