Abstract
The invention discloses a special compound fertilizer formula for producing hilly barren-land corns by using ardealite-treated medical stones as a filler. The special compound fertilizer formula is characterized by comprising the following steps of: mixing ardealite having very strong acidity and silicate medical stones in the ratio of 1:1 and stacking for 3-5 days so that the medical stones are converted into water-soluble sulfate which is easily absorbed by crops and the fertilizer efficiency is improved; then smashing 1.4-1.6 parts of filler, mixing the filler, 4.4-4.6 parts of urea, 2.9-3.1 parts of monoammonium phosphate and 0.9-1.1 parts of potassium chloride according to the fertilizer requirement law of the hilly barren-land corns, and pelletizing; drying and packaging; and putting on the market for production, wherein the total nutrient of nitrogen, phosphorus and potassium in a compound fertilizer is 43% and the ratio of nitrogen to phosphorus to potassium is 24:13:6. Many-year multi-site experiments prove that the cost of the formula per ton is reduced by more than 100 Yuan compared with the cost of a formula using white clays as the filler, and the yield of the hilly barren-land corns produced by applying a bag of the compound fertilizer per mu can be higher than that of the hilly barren-land corns produced by singly applying 3-5 bags of urea per mu.
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 hummock book 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 hummock book ground corn special-purpose compound fertilizer that specific aim is very strong.
Summary of the invention
The present invention, for the fertilising of hummock book 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 1.4~1.6 parts of its stopping composition, compatibility is pulverized 4.4~4.6 parts, rear urea, 2.9~3.1 parts of monoammonium phosphates, 0.9~1.1 part, Repone K, blending granulation.Drying and packaging, puts on market, for the production of, this Chemical Mixed Fertilizer nitrogen, phosphorus, potassium total nutrient are 43%, three is than being 24:13:6.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 150 kilograms, 450 kilograms, the urea after blending is pulverized, 300 kilograms of monoammonium phosphates, 100 kilograms, Repone K, granulation is dried, and reaching nitrogen, phosphorus, potassium total nutrient is 43%, three is than the hummock book ground corn special-purpose compound fertilizer for 24:13:6, and concrete blending parameter is seen following table:
Claims (3)
1. one kind is that stopping composition is produced hummock book 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 1.4~1.6 parts of its stopping composition, compatibility is pulverized 4.4~4.6 parts, rear urea, 2.9~3.1 parts of monoammonium phosphates, 0.9~1.1 part, 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 43%, three is than being 24:13:6.
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.
