Problems solved by technology

However, in this method, alkaline plant ash and monoammonium phosphate are directly mixed with urea, which is likely to cause phosphorus fixation and urea loss, and the amount of plant ash in the compound fertilizer is small, and plant ash cannot be used in large quantities.
Chinese Patent Publication No. CN101020612A discloses a kind of plant organic potassium fertilizer, and the amount of plant ash is relatively large, but the nitrogen and phosphorus nutrient content is low, and a large amount of application will increase the labor cost

Embodiment 1

[0028] Take by weighing 40kg of plant ash with 80 mesh sieve and place it in the disk of disc granulator, rotate the disk, and spray 4000ml of 1.8M H2SO4 solution at the same time, then respectively pass 20kg of granular calcium superphosphate through 80 mesh sieve, chlorine Put 10kg of potassium chloride and 30kg of urea into the disc of the disc granulator in turn, turn the disc to fully mix the raw materials; after the raw materials are mixed evenly, start the water spray device, and turn the disc at the same time, and stop spraying after spraying 8 kg of water. water. Continue to rotate the disk to granulate, and when most of the fertilizer granularity reaches the corresponding requirements of GB15063-2001, place it in a drying tower at 80°C and dry until the moisture is less than 5%. , cooling, the fertilizer is sieved, and the particle size meets the fertilizer weighing and packaging of GB15063-2001 requirements to obtain a special mixed fertilizer for green plums of the...

Embodiment 2

[0030] Weigh 40kg of plant ash through a 80-mesh sieve and place it in the disk of the disk granulator, rotate the disk, and spray 1.8M H at the same time 2 SO 4 Solution 4000ml, then add 25kg of granular calcium superphosphate, 10kg of potassium chloride, and 25kg of urea that have passed through an 80-mesh sieve to the disc of the disc granulator in turn, and turn the disc to fully mix the raw materials; mix the raw materials evenly Finally, start the water spray device, rotate the disc at the same time, and stop the water spray after spraying 12kg of water. Continue to rotate the disc to granulate. When the particle size of most fertilizers meets the corresponding requirements of GB15063-2001, place them in a drying tower at 80°C and dry until the moisture is less than 5%. , cooling, the fertilizer is sieved, and the particle size meets the fertilizer weighing and packaging of GB15063-2001 requirements, which obtains a kind of green plum special mixed fertilizer of the pre...

Embodiment 3

[0032] Weigh 40kg of plant ash through a 80-mesh sieve and place it in the disk of the disk granulator, rotate the disk, and spray 1.8M H at the same time 2 SO 4 Solution 4000ml, then add 25kg of granular calcium superphosphate, 15kg of potassium chloride, and 20kg of urea that have been passed through an 80-mesh sieve to the disc of the disc granulator in turn, and rotate the disc to fully mix the raw materials; mix the raw materials evenly Finally, start the water spray device, turn the disc at the same time, and stop the water spray after spraying 10kg of water. Continue to rotate the disc to granulate. When the particle size of most fertilizers meets the corresponding requirements of GB15063-2001, place them in a drying tower at 80°C and dry until the moisture is less than 5%. , cooling, the fertilizer is sieved, and the particle size meets the fertilizer weighing and packaging of GB15063-2001 requirements, which obtains a kind of green plum special mixed fertilizer of th...

Abstract

The invention discloses a green plum special mixed fertilizer mainly produced by plant ash, which belongs to the technical field of agricultural fertilizers. The weight ratio of each component of the mixed fertilizer is: plant ash 40-45, calcium superphosphate 20-30, chemical potassium fertilizer 10-15, urea 15-30, acidity regulator 0.8-1.2; , mixed granulation, drying, screening and packaging preparation. The fertilizer of the invention has a total nutrient content of more than 25 percent of nitrogen, phosphorus and potassium, and contains medium and micronutrient elements. The fertilizer is in granular form for easy application.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special mixed fertilizer for green plums. Background technique [0002] The massive consumption of fossil energy has caused the continuous deterioration of the ecological environment. Biomass energy is a kind of green renewable energy. The development of biomass power generation and heating industry has far-reaching significance for promoting energy conservation and emission reduction. At present, more than 20 biomass direct combustion power generation projects in my country have been completed or are under construction, producing more than 160,000 tons of plant ash every year. According to the medium and long-term plan for renewable energy issued by the National Development and Reform Commission, by 2010, the annual utilization of biomass solid briquette fuel in the country will reach 1 million tons. By 2020, the total installed capacity of biomass power ge...
