Abstract
The invention relates to a formula for producing a special compound fertilizer for medium fertile land corn with phosphogypsum processed medical stone as a filler. The formula is characterized in that phosphogypsum having an extremely strong acidity is blended with medical stone according to a ratio of 1:1, and the obtained mixture is piled for 3-5d, so medical stone is converted into water soluble sulfate easy to absorb, thereby the fertilizer efficiency is improved; and the obtained phosphogypsum processed medical stone is used as a filler, 0.9-1.1 parts of the filler is blended with 4.4-4.6 parts of crushed urea, 2.9-3.1 parts of monoammonium phosphate and 1.4-1.6 parts of potassium chloride according to the fertilizer needing rule of the medium fertile land corn, the obtained mixture is granulated, dried and packaged, the total nutrients of N, P and K in the compound fertilizer is 46%, and a ratio of N:P:K is 24:13:9. Multi-year multi-point tests prove that the cost of the formula is above 100 yuan/t lower than the cost of the use of kaolin as a filler, and the output of 666.7m<2> soil fertilized with one bag of the compound fertilizer is higher than the output of 666.7m<2> soil fertilized with 3-5 bags of urea.
Description
design field
The present invention relates to fertilization compositions based on earth measurement chemical fertilizer field, being specifically related to process medical stone with phosphogypsum is stopping composition, and other source of manure of compatibility is produced medium fertile ground corn special-purpose compound fertilizer.
Background technology
China's great majority are produced compound fertilizer enterprises, and large multiplex white earthenware soil is made stopping composition, and now using phosphogypsum processing medical stone instead is stopping composition.Because phosphogypsum acidity is extremely strong, process silicate medical stone, can make its change into can be water-soluble easy vitriol absorbed by crops, make multiple beneficial trace element in medical stone, energy utilization absorbed by crops, thereby not only improved fertilizer efficiency.And, also making one ton of composite fertilizer of every production, its cost can also save and prop up more than 100 yuan.Use its stopping composition, according to surveying native analysis data, according to the principle of balance fertilizing " law of cask ", other source of manure of compatibility, produces the medium fertile ground corn special-purpose compound fertilizer that specific aim is very strong.
Summary of the invention
The present invention, for the fertilising of medium fertile ground corn, reaches the object of increasing income and economizing on spending.The present invention adopts following technical scheme: first, in the ratio of 1:1, phosphogypsum and medical stone are carried out to blending, pile at normal temperatures vexed 3～5 days, make acid extremely strong phosphogypsum, silicate medical stone change into can be water-soluble easy vitriol absorbed by crops.With 0.9～1.1 part of its stopping composition, compatibility is pulverized 4.4～4.6 parts, rear urea, 2.9～3.1 parts of monoammonium phosphates, 1.4～1.6 parts, Repone K, blending granulation.Drying and packaging, puts on market, for the production of, this Chemical Mixed Fertilizer nitrogen, phosphorus, potassium total nutrient are 46%, three is than being 24:13:9.Because this formula is that scientific matching forms on the basis of surveying soil chemical examination, there is very strong specific aim, through multiple years evidence, execute one bag of this Chemical Mixed Fertilizer for every mu, the comparable output of singly executing 3～5 bags of urea is high.
Specific embodiments
First, in the ratio of 1:1, phosphogypsum and medical stone are carried out to blending, pile at normal temperatures vexed 3～5 days, make acid extremely strong phosphogypsum, silicate medical stone change into can be water-soluble easy vitriol absorbed by crops.With its 100 kilograms, 450 kilograms, the urea after blending is pulverized, 300 kilograms of monoammonium phosphates, 150 kilograms, Repone K, granulation is dried, and reaching nitrogen, phosphorus, potassium total nutrient is 46%, three is than the medium fertile ground corn special-purpose compound fertilizer for 24:13:9, and concrete blending parameter is seen following table:
Claims (2)
1. one kind is that stopping composition is produced medium fertile ground corn special-purpose compound fertilizer formula with phosphogypsum processing medical stone, it is characterized in that: first in the ratio of 1:1, phosphogypsum and medical stone are carried out to blending, pile at normal temperatures vexed 3～5 days, make acid extremely strong phosphogypsum, silicate medical stone change into can be water-soluble easy vitriol absorbed by crops, and then by design nutrient, with 0.9～1.1 part of its stopping composition, compatibility is pulverized 4.4～4.6 parts, rear urea, 2.9～3.1 parts of monoammonium phosphates, 1.4～1.6 parts, Repone K, blending granulation.
2. drying and packaging, puts on market, for the production of, this Chemical Mixed Fertilizer nitrogen, phosphorus, potassium total nutrient are 46%, three is than being 24:13:9.
3, because this formula is that scientific matching forms on the basis of surveying soil chemical examination, have very strong specific aim, through multiple years evidence, execute one bag of this Chemical Mixed Fertilizer for every mu, the comparable output of singly executing 3～5 bags of urea is high.
