CN103819242A - Special compound fertilizer formula for producing leaf mustards by using ardealite-treated medical stones as filler - Google Patents

Abstract

The invention discloses a special compound fertilizer formula for producing leaf mustards 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 of: 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, 3.9-4.1 parts of urea, 0.9-1.1 parts of ammonium chloride, 0.9-1.1 parts of monoammonium phosphate and 1.9-2.1 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 38% and the ratio of nitrogen to phosphorus to potassium is 22:4:12. Since being scientifically prepared based on soil tests, the formula has strong effectiveness. Many-year multi-site experiments prove that the yield of the leaf mustards produced by applying a bag of the compound fertilizer per mu can be higher than that of the leaf mustards produced by singly applying 3-5 bags of urea per mu.

Description

Processing medical stone with phosphogypsum is that stopping composition is produced leaf mustard compound fertilizer special formula

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 leaf mustard 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 leaf mustard compound fertilizer special that specific aim is very strong.

Summary of the invention

The present invention, for the fertilising of leaf mustard, 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 3.9～4.1 parts, rear urea, 0.9～1.1 part of ammonium chloride, 0.9～1.1 part of monoammonium phosphate, 1.9～2.1 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 38%, three is than being 22:4:12.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, 400 kilograms, the urea after blending is pulverized, 100 kilograms of ammonium chlorides, 100 kilograms of monoammonium phosphates, 200 kilograms, Repone K, granulation is dried, reaching nitrogen, phosphorus, potassium total nutrient is 38%, and three is than the leaf mustard compound fertilizer special for 22:4:12, and concrete blending parameter is seen following table:

Claims (3)

1. one kind is that stopping composition is produced leaf mustard 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 3.9～4.1 parts, rear urea, 0.9～1.1 part of ammonium chloride, 0.9～1.1 part of monoammonium phosphate, 1.9～2.1 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 38%, three's ratio is 22: 4: 12.

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.
