Safe and harmless chemical fertilizer and preparation method thereof

Abstract

The invention discloses a safe and harmless chemical fertilizer and a preparation method of the safe and harmless chemical fertilizer. The safe and harmless chemical fertilizer comprises the following raw materials in parts by weight: 50-80 parts of carbon phosphorus potassium, 60-70 parts of ammonium molybdate heptahydrate, 35-45 parts of polypropylene compound, 55-60 parts of sodium dodecyl benzene sulfonate, 10-20 parts of sulfate, 20-30 parts of 2, 4-dinitrophenol, 35-65 parts of lauryl alcohol ethoxy ammonium sulfate, 50-60 parts of glycerin, 20-30 parts of boric acid, 10-30 parts of potassium fluoride, 35-45 parts of potassium bromate and 30-50 parts of nitrosalicylic acid. The preparation method comprises the steps of evenly mixing the raw materials, heating for reaction and cooling. The safe and harmless chemical fertilizer has a certain yield improvement function for crops, is capable of maintaining the soil to be in a normal state and is lower in influence to the soil; the safe and harmless chemical fertilizer almost has no influence to the content of cadmium, mercury and copper in the soil, and the content of harmful substances in the soil is not increased by the chemical fertilizer, so that the chemical fertilizer is safe and harmless.

Description

technical field [0001] The invention relates to a chemical fertilizer, in particular to a safe and harmless chemical fertilizer and a preparation method thereof. Background technique [0002] Chemical fertilizers are fertilizers made by chemical and physical methods that contain one or several nutrient elements needed for the growth of crops. The abbreviation of chemical fertilizers. Chemical fertilizers containing only one nutrient element that can be marked are called unit fertilizers, such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, and minor macro element fertilizers and trace element fertilizers. Chemical fertilizers that contain two or three of the three nutritional elements nitrogen, phosphorus, and potassium and whose content can be indicated are called compound fertilizers or mixed fertilizers. The solubility of the active components of a fertilizer in water is usually a measure of the effectiveness of a fertilizer. Grade is the main ind...
