Humic acid multi-element compound mixed phosphate fertilizer and production method thereof

Abstract

The invention discloses a humic acid multi-element compound mixed phosphate fertilizer. The humic acid multi-element compound mixed phosphate fertilizer comprises the following components in parts by mass: 80-120 parts of diammonium phosphate, 120-150 parts of polypeptide potassium L-aspartate, 240-280 parts of nano calcium carbonate, 70-100 parts of phosphogypsum, 20-40 parts of purple coneflower leaf residue, 30-50 parts of humic acid, 8-20 parts of cremart, 80-120 parts of multi-element compound fertilizer, 10-14 parts of microbial fermentation inoculum and 30-50 parts of microbial phosphate-solubilizing preparation. The humic acid multi-element compound mixed phosphate fertilizer provided by the invention is very convenient to use; and after being applied to soil, the property of the soil can be deep improved. The microbial phosphate-solubilizing preparation is used in the invention, thereby being beneficial to improving the soil and increasing the utilization ratio of the phosphorus element in the soil.

Description

technical field [0001] The invention relates to a humic acid multi-component compound phosphate fertilizer and a production method thereof. Background technique [0002] Soil secondary salinization, also known as "secondary salinization", refers to the process of turning good cultivated land into "salinization" due to unreasonable cultivation and irrigation measures and changes in vegetation. It mainly occurs in my country's North China Plain, Songliao Plain, Hetao Plain, Weihe Plain and other places. There are three main reasons for the formation of secondary salinization: First, the drainage system of farmland is not smooth, and a large amount of water diversion irrigation has raised the groundwater level, increased the speed of groundwater moving upward through the soil capillary and the evaporation of groundwater, thereby increasing the groundwater and the lower level. The salt in the soil accumulates to the surface. Second, unreasonable irrigation destroys the original...

There are three main reasons for the formation of secondary salinization: First, the drainage system of farmland is not smooth, and a large amount of water diversion irrigation has raised the groundwater level, increased the speed of groundwater moving upward through the soil capillary and the evaporation of groundwater, thereby increasing the groundwater and the lower level. The salt in the soil accumulates to the surface. Second, unreasonable irrigation destroys the original soil salt water balance. Third, unreasonable agricultural production measures and destruction of vegetation aggravate the evaporation of soil water in the cultivated layer, resulting in surface alkali accumulation.
