Abstract
The invention discloses a special compound fertilizer formula for producing head cabbages by using ardealite-treated medical stones as a filler. White clays which are used as the filler by most of Chinese compound fertilizer production enterprises are replaced by the ardealite-treated medical stones as the filler. As ardealite having very strong acidity is used for treating silicate medical stones, a plurality of beneficial trace elements in the medical stones can be converted into water-soluble sulfate which is easily absorbed by crops, thus the fertilizer efficiency is improved and the cost of the formula per ton is reduced by more than 100 Yuan compared with the cost of a formula using the white clays as the filler. The special compound fertilizer formula is prepared by the following steps: mixing ardealite and medical stones in the ratio of 1:1 according to soil testing data and a 'cannikin law' principle of balanced fertilization; stacking for 3-5 days at normal temperature; then smashing 1.9-2.1 parts of filler, mixing the filler, 2.9-3.1 parts of urea, 1.9-2.1 parts of monoammonium phosphate and 2.9-3.1 parts of potassium chloride according to designed nutrients, 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 42% and the ratio of nitrogen to phosphorus to potassium is 16:8:18. Since being scientifically prepared based on soil tests, the formula has strong effectiveness. Many-year multi-site experiments prove that the yield of the head cabbages produced by applying a bag of the compound fertilizer per mu can be higher than that of the head cabbages 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 cabbage compound fertilizer special.
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 cabbage compound fertilizer special that specific aim is very strong.
Summary of the invention
The present invention, for the fertilising of cabbage, 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 1.9~2.1 parts of its stopping composition, compatibility is pulverized 2.9~3.1 parts, rear urea, 1.9~2.1 parts of monoammonium phosphates, 2.9~3.1 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 42%, three is than being 16:8:18.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 200 kilograms, 300 kilograms, urea after blending is pulverized, 200 kilograms of monoammonium phosphates, 300 kilograms, Repone K, granulation is dried, and reaching nitrogen, phosphorus, potassium total nutrient is 42%, and three is than the cabbage compound fertilizer special for 16:8:18, and concrete blending parameter is seen following table:
Claims (3)
1. one kind is that stopping composition is produced cabbage compound fertilizer special 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 1.9~2.1 parts of its stopping composition, compatibility is pulverized 2.9~3.1 parts, rear urea, 1.9~2.1 parts of monoammonium phosphates, 2.9~3.1 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 42%, three's ratio is 16: 8: 18.
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.
