Abstract
The invention relates to a formula for producing a special compound fertilizer for watermelons with phosphogypsum processed medical stone as a filler. Most Chinese compound fertilizer production enterprises use kaolin as a filler, the phosphogypsum processed medical stone is used as a filler in the invention, phosphogypsum has an extremely strong acidity, and the processing of silicate medical stone by the phosphogypsum enables beneficial trace elements in the medical stone to be converted into water soluble sulfate easy to absorb, so the fertilizer efficiency is improved, and the cost of the use of the phosphogypsum processed medical stone as a filler is above 100 yuan/t lower than the cost of the use of kaolin as a filler. Phosphogypsum is blended with medical stone according to a ratio of 1:1 according to the balanced fertilizing Cannikin law in terms of soil test data, the obtained mixture is piled at normal temperature for 3-5d, the obtained phosphogypsum processed medical stone is used as a filler, 1.4-1.6 parts of the filler is blended with 4.4-4.6 parts of crushed urea, 1.9-2.1 parts of monoammonium phosphate and 1.9-2.1 parts of potassium sulfate according to designed nutrients, and the obtained mixture is granulated. The granulated mixture is dried and packaged, the finally obtained compound fertilizer is put on the market to be used for production, the total nutrients of N, P and K in the compound fertilizer is 41%, and a ratio of N:P:K is 23:8:10. The formula is obtained through scientific matching based on soil test and has a very strong pertinence, and multi-year multi-point tests prove that 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 compound fertilizer special for watermelons.
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 compound fertilizer special for watermelons that specific aim is very strong.
Summary of the invention
The present invention, for the fertilising of watermelon, 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, 1.9～2.1 parts of monoammonium phosphates, 1.9～2.1 parts of potassium sulfate, blending granulation.Drying and packaging, puts on market, for the production of, this Chemical Mixed Fertilizer nitrogen, phosphorus, potassium total nutrient are 41%, three is than being 23:8:10.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 300 kilograms, 350 kilograms, urea after blending is pulverized, 150 kilograms of monoammonium phosphates, 350 kilograms, Repone K, granulation is dried, and reaching nitrogen, phosphorus, potassium total nutrient is 44%, and three is than the compound fertilizer special for watermelons for 17:6:21, and concrete blending parameter is seen following table:
Claims (3)
1. one kind is that stopping composition is produced compound fertilizer special for watermelons 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, 1.9～2.1 parts of monoammonium phosphates, 1.9～2.1 parts of potassium sulfate, blending granulation.
2. drying and packaging, puts on market, for the production of, this Chemical Mixed Fertilizer nitrogen, phosphorus, potassium total nutrient are 41%, three is than being 23:8:10.
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.
