Embodiment 1
[0022] Embodiment 1, prepare polypeptide fertilizer synergist 100kg
[0023] Weigh raw material potassium ammonium polyaspartate 0.7kg (0.7%), calcium powder 91.3kg (91.3%), water 8kg (8%) by proportioning, the above-mentioned calcium powder weighed by proportioning is pulverized, polyaspartic acid After potassium ammonia is dissolved in water to form a solution, it is evenly sprayed on the calcium powder, and after being fully stirred, it is granulated by a disc granulator; the granulated particles are screened with a vibrating screen to ensure the particle size; The particle size of the spherical particles is 2.0mm-4.0mm, and the ball forming rate is 85%-95%. It is dried in a drum dryer at a drying temperature of 110°C, and is cooled by suction in a drum cooler. After reaching normal temperature, it is measured and packaged into bags to make a polypeptide fertilizer synergist.
Embodiment 2
[0024] Embodiment 2, prepare polypeptide fertilizer synergist 100kg
[0025] Weigh raw material potassium ammonium polyaspartate 3.5kg (3.5%), calcium powder 87kg (87%), water 9.5kg (9.5%) by proportioning, the above-mentioned calcium powder weighed by proportioning is pulverized, polyaspartic acid After potassium ammonia is dissolved in water to form a solution, it is evenly sprayed on the calcium powder, and after being fully stirred, it is granulated by a disc granulator; the granulated particles are screened with a vibrating sieve to ensure the particle size; The particle size of the spherical particles is 2.0mm-4.0mm, and the ball forming rate is 85%-95%. It is dried in a drum dryer at a drying temperature of 120°C, and is cooled by suction in a drum cooler. After reaching normal temperature, it is measured and packaged into bags to make a polypeptide fertilizer synergist.
Embodiment 3
[0026] Embodiment 3, preparation polypeptide fertilizer synergist 100kg
[0027] Weigh raw material Potassium Ammonium Aspartate 5kg (5%), calcium powder 84kg (84%), water 11kg (11%) by proportioning, the above-mentioned calcium powder weighed by proportioning is pulverized, Potassium Aminopotassium Polyaspartate After being dissolved in water to form a solution, it is evenly sprayed on the calcium powder, and after being fully stirred, it is granulated by a disc granulator; the granulated particles are screened with a vibrating sieve to ensure the particle size; spherical particles The particle size is 2.0mm-4.0mm, and the ball forming rate is 85%-95%. It is dried in a tumble dryer at a drying temperature of 130°C. It is ventilated and cooled in a tumble cooler, and cooled to room temperature. After that, it is measured and packaged into bags to make a polypeptide fertilizer synergist.
