Embodiment 1

[0017] A crop fertilizer made from raw materials of the following qualities:

[0018] Weathered lignite 100Kg, gluconic acid 12Kg, ammonium nitrohumate 80Kg, dicyandiamide 8Kg, urea 40Kg, trace elements 0.2Kg (including zinc 0.05Kg, iron 0.08Kg, boron 0.04Kg, copper 0.03Kg) and organic matter 120Kg ;

[0019] Its preparation method comprises the following steps:

[0020] A. Add 100Kg weathered lignite and 12Kg gluconic acid into a reactor equipped with 120Kg water, stir evenly, and react, and the reaction temperature is maintained at 25°C;

[0021] B. After the reaction time described in step A reaches 2 hours, add 80Kg of ammonium nitrohumate to it, stir evenly, and heat to 65°C, react for 30min, then add 8Kg of dicyandiamide, and continue to react at 65°C for 5min ;

[0022] C. After the reaction described in step B is finished, stop heating, then adjust the pH value to neutral with potassium hydroxide, then mix evenly with 40Kg urea, 0.2Kg trace elements, and 120Kg or...

Abstract

The invention discloses a chemical fertilizer for crops, and belongs to the field of chemical engineering. The chemical fertilizer for crops is prepared by taking 25 parts of leonardite, 3 parts of gluconic acid, 20 parts of ammonium nitro humate, 2 parts of dicyandiamide, 10 parts of urea, 0.05 part of trace elements and 30 parts of organic matters by weight as raw materials through the steps of reacting the leonardite and gluconic acid in water firstly; then, adding ammonium nitro humate into the obtained product to carry out a reaction under heating, adding dicyandiamide to react, and after the reacting is completed, adjusting the PH value to be neutral; finally, uniformly mixing the obtained product with urea, the trace elements and the organic matters. The chemical fertilizer for crops disclosed by the invention is mainly designed for crops, and has the effects of less application amount, high utilization rate, long fertilizer efficiency duration, and capability of improving the properties of soil, increasing the nutrition of crops, and increasing the yield of crops; the residues of the chemical fertilizer in crops are little, therefore, the chemical fertilizer does not cause damage to a human body.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a crop chemical fertilizer. Background technique [0002] Since the synthesis of chemical fertilizers in the 19th century, chemical fertilizers have been widely used because they can greatly increase the yield of crops. However, with the wide application of chemical fertilizers, its shortcomings have gradually been recognized by people: 1) The fertilizer efficiency time period of chemical fertilizers is not high, and the amount of use is large; 2) Excessive use of chemical fertilizers will destroy the structure of the soil and acidify the soil 3) Chemical fertilizers remain in the crops, thus affecting human health. Obviously, such chemical fertilizers do not meet the requirements of the times, and people urgently need a new type of chemical fertilizer with high efficiency and harmlessness. Contents of the invention [0003] The invention provides a crop chemical fertilizer, ...
