Abstract
The present invention provides an efficient compound fertilizer. The efficient compound fertilizer includes the following components by weight: 415-420 parts of urea, 220-240 parts of diammonium phosphate, 190-200 parts of potassium sulfate, and 10 parts of clay. The efficient compound fertilizer of the present invention can significantly increase crop yields under the circumstance of using the same amount of fertilizer.
Description
Technical field
The invention belongs to the agrochemical field, be specifically related to a kind of compound manure.
Background technology
Present composite fertilizer on the market is of a great variety, but the applicant thinks that its effect of increasing production is also not obvious.
Summary of the invention
The invention provides the obvious efficient compound fertilizer of a kind of effect of increasing production.
The invention provides to achieve these goals a kind of efficient compound fertilizer, described efficient compound fertilizer contains each component of following mass fraction:
Wilkinite 100-120 part, urea 415-420 part, diammonium phosphate 220-240 part, vitriolate of tartar 190-200 part, 10 parts of clays.
Preferably, described efficient compound fertilizer contains the component of following mass fraction: 110 parts of wilkinites, 416 parts in urea, 230 parts of diammonium phosphate, 195 parts of vitriolate of tartar, 10 parts of clays.
The beneficial effect that the technical scheme that the embodiment of the invention provides is brought is: efficient compound fertilizer of the present invention can in the identical situation of rate of fertilizer application, significantly improve crop yield.
Embodiment
Embodiment 1
The composition of raw materials of efficient compound fertilizer of the present invention is as follows:
Wilkinite 110kg, urea 416kg, diammonium phosphate 230kg, vitriolate of tartar 195kg, clay 10kg.
Wherein: the mass percent of N element is 22%, P in the diammonium phosphate
2O
5Mass percent be 44%; K in the vitriolate of tartar
2The mass percent of O is 50%, and the mass percent of N element is 46% in the urea.
The preparation method of efficient compound fertilizer of the present invention is as follows:
Above-mentioned raw materials is thrown to batch bin continuously by above-mentioned prescription; through being transported in the crusher broken by rotary conveyor behind the automatic batching system; cross 60 mesh sieves; send into again the granulation of rotary drum granulator spraying steam; barrel linear velocity 1 meter per second; raw material after the granulation sent in the dryer dry; bake out temperature is 60 ℃, and drying time is 20 minutes, the raw material after the oven dry is sent into cooler cool off; raw material after the oven dry is cooled to room temperature; through one-level screening and secondary screening, filter out the efficient compound fertilizer particle of diameter between 2.5mm-3.0mm successively, it is entered fertilizer coating machine coating anti-caking; metering packing gets efficient compound fertilizer of the present invention.
