Polypeptide fertilizer synergistic agent and preparation method thereof

Abstract

The invention discloses a polypeptide fertilizer synergistic agent, relating to a fertilizer synergistic agent, namely a broad-spectrum plant nutrient absorption promoter, particularly a polypeptide fertilizer synergistic agent and a preparation method thereof which are applicable to agriculture production, flower culture and plant husbandry. The synergistic agent is prepared by evenly mixing poly potassium aspartate with calcium powder according to a mixture ratio, and the weight percentage mixture ratios of materials are as follows: 0.7-5 percent of poly potassium aspartate, 84-91.3 percent of calcium powder and the balance of water; and the total amount is 100 percent. The preparation method of the polypeptide fertilizer synergistic agent comprises the steps of weighing the materials of the poly potassium aspartate, the calcium powder and the water according to mixture ratio, putting the calcium powder weighed by mixture ratio into a stirring mixer, dissolving the poly potassium aspartate in the water to form a solution, evenly spraying the solution on the calcium powder, fully stirring and mixing, then balling and granulating; screening for ensuring granularity; and drying in a rotary drum dryer with drying temperature of 110-130 DEG C, air-extracting cooling to achieve normal temperature, then measuring and packing, thus preparing the polypeptide fertilizer synergistic agent.

Description

technical field

[0001] The invention relates to a fertilizer synergist, that is, a broad-spectrum plant nutrient absorption accelerator, in particular to a polypeptide fertilizer synergist and a preparation method thereof, which are suitable for agricultural production, flower cultivation and garden planting. Background technique

[0002] At present, my country accounts for 7% of the world's land and consumes 30% of the world's total chemical fertilizers, and the amount of fertilizer per unit area has reached three times the world's average level, which shows that my country's traditional waste of money is very serious. According to the Institute of Soil and Fertilizer Research Institute of the Chinese Academy of Agricultural Sciences, the absorption rate of nitrogen fertilizer in the current season in my country is only 35%, and the seasonal utilization of phosphorus is only 10% to 30%. The reduction in the utilization rate of chemical fertilizers has caused energy waste, a...
