Humic acid carbon source topdressing formula and preparation method thereof

Abstract

The invention relates to the technical field of agricultural fertilizers, and particularly relates to a humic acid carbon source topdressing formula and a preparation method thereof. The formula comprises the following components: weathered coal, humic acid, fulvic acid, nitrogen, ammonium bicarbonate, potassium hydroxide, monopotassium phosphate, potassium sulfate, boric acid and magnesium sulfate. The formula is characterized in that the dosage of each material is as follows: 70% of weathered coal, 40-50% of humic acid, 20-30% of fulvic acid, 15% of nitrogen, 10% of ammonium bicarbonate, 10%of potassium hydroxide, 6-8% of monopotassium phosphate, 10% of potassium sulfate, 5% of boric acid and 3% of magnesium sulfate. The formula structure improves the fertilizer utilization rate, effectively solves the problems of fertility reduction and fertilizer removal in middle and later periods of crops, makes the fertilizer efficiency more durable, and improves and enhances the stress resistance of plants.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a humic acid carbon source top dressing formula and a preparation method thereof. Background technique [0002] Fertilizer refers to a class of substances that provide one or more essential nutrient elements for plants, improve soil properties, and increase soil fertility levels. It is one of the material bases of agricultural production, mainly including ammonium phosphate fertilizers, water-soluble fertilizers with a large number of elements , medium element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. my country is the world's largest producer and consumer of chemical fertilizers. Continuous large-scale application of chemical fertilizers has increased crop yields for a certain period of time and to a certain extent, but The harm to the environment and human beings is increasing d...

[0002] Fertilizer refers to a class of substances that provide one or more essential nutrient elements for plants, improve soil properties, and increase soil fertility levels. It is one of the material bases of agricultural production, mainly including ammonium phosphate fertilizers, water-soluble fertilizers with a large number of elements , medium element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. my country is the world's largest producer and consumer of chemical fertilizers. Continuous large-scale application of chemical fertilizers has increased crop yields for a certain period of time and to a certain extent, but The harm to the environment and human beings is increasing day by day, such as the increase of heavy metals and toxic elements in the soil, soil acidification, compaction, and fertility decline. A series of serious ecological and environmental problems and human health problems, so a humic acid carbon source topdressing fertilizer formula and its preparation method are needed to improve the above problems
