Abstract
The present invention provides a raw material formula of potassium-magnesium fertilizer and its preparation method. It is mainly characterized by that it is a potassium-magnesium fertilizer which has cirtric solubility and contains several elements of potassium, magnesium, calcium and silicon, etc. and is prepared by using mineral raw materials of 30-55% of potash feldspar, 15-25% of magnesian spar and 15-30% of limestone through a ''two-grinding one-calcining'' process.
Description
Technical field
The invention belongs to technical field of fertilizers, relate to prescription of a kind of potassic-magnesian fertilizer and preparation method thereof.
Background technology
Potash fertilizer is indispensable constant fertilizer in the various plant growing processes, generally investigate through Chinese soil, the general potassium deficiency of whole nation soil, the Ministry of Agriculture carries out soil in China and mends the potassium engineering, prior art utilizes potassium felspar sand to make potash fertilizer through blast-furnace roasting, not only production cost height, and crop absorption amount is little; Fertiliser containing magnesium is a necessary middle amount fertilizer in the various plant growing processes, and Chinese soil generaI investigation earth magnesium deficiency is on the rise with showing the whole nation, and prior art utilizes sal epsom to make fertilizer, and not only price height, and long-term application can cause soil compaction and acid base imbalance.The Chinese soil generaI investigation shows the whole nation 60% geographic soil calcium deficiency silicon, particularly south rice growing area and the serious calcium deficiency silicon of central plain area's soil again, and prior art utilizes unslaked lime to make fertilizer, but the crop absorption amount is less.
Summary of the invention
The contriver is in be engaged in agriculture for a long time research and technology popularization process, through a large amount of investigations, constantly test improves, utilize reserves abundant potassium felspar sand, rhombspar, Wingdale, raw mineral materialss such as coal, purpose is to develop a kind of defective that can overcome existing potassic-magnesian fertilizer preferably, can be by composition of raw materials and preparation technology's method thereof of the easy potassic-magnesian fertilizer that contains potassium, magnesium, calcium, the multiple element of silicon that absorbs of farm crop.
For realizing the object of the invention, the technical solution used in the present invention is to adopt following weight part raw mineral materials: potassium felspar sand 30-55%, and rhombspar 15-25%, Wingdale 15-30%, coal 6-18% becomes a kind of potassic-magnesian fertilizer through processing and preparing.
Wherein potassium felspar sand can utilize and contain K
2O on average more than 13%, contains SiO
2Average mineral about 10%; Rhombspar can utilize and contain MgO on average more than 15%, contains SiO
2Equal mineral about 10%; Wingdale can utilize and contain CaO on average at the mineral more than 40%, and it is good at the hard coal of 5500 kilocalories/more than the kilogram that coal can utilize thermal value, not only can be used as fuel but also can be used as raw material, contains MgO, K in the coal
2O, SiO
2On average at 3%-5%.
The present invention adopts following processing and preparing processing method to described raw material: raw material, and--------mixed--------------------abrasive dust----packs the powdery finished product to the system ball to abrasive dust in ripe ball fragmentation in calcining in fragmentation.Also can be with the powdery finished product--------granular finished product is packed in oven dry----in granulation.
Because the present invention is through repeatedly trial-production repeatedly, on probation, update perfect, first above-mentioned prescription raw mineral materials is become a kind of citric soluble potassium that contains that has through above-mentioned " two mills, one calcination method " processing method preparation, magnesium, calcium, the potassic-magnesian fertilizer material of silicon multielement, realized mineral are become the fertilizer that farm crop directly absorb easily, through country, economize, ground agricultural experts in the land for growing field crops to the multiple kinds of crops controlled trial, can not only overcome existing potassium, magnesium, the defective that calcareous fertilisers exist, cost reduces, improve Soil structure, change soil compaction, and received significant increasing of quality and production effect, have vast market prospect.
Embodiment
The formulation Example 1 of a kind of potassic-magnesian fertilizer of the present invention adopts following weight part raw mineral materials: potassium felspar sand 30%, rhombspar 25%, Wingdale 30%, hard coal 15%; The above-mentioned raw materials mineral are broken into 1-2cm twice through crusher
3Granular, be mixed in proportion, become 80-120 purpose powdery through ball mill grinding, add water through nodulizer and make 0.3-1.5cm
3Spherical, send into mechanical shaft kiln burning, temperature is controlled at 1100-1300 ℃, send into ball mill after the ripe ball warp crusher in crushing of will luming and wear into 100-120 purpose powdery, packing is the powdering finished product, also can be with the powdery product after the nodulizer granulation, the finished product that promptly granulates is packed in oven dry.
The formulation Example 2 of a kind of potassic-magnesian fertilizer of the present invention adopts following weight part raw mineral materials, potassium felspar sand 55%, and rhombspar 20%, Wingdale 15%, hard coal 10% is prepared from by the production technique of embodiment 1.
The formulation Example 3 of a kind of potassic-magnesian fertilizer of the present invention, adopt following weight part raw mineral materials: potassium felspar sand 42%, rhombspar 15%, Wingdale 25%, hard coal 18% is prepared from by the production technique of embodiment 1.
Above-mentioned formulation Example, in producing preparation, ripe ball material contains K through the sampling chemical examination
2O3.5-8% contains MgO4.5-8.5%, contains CaO15-25%, contains SiO
220-52%.
This potassic-magnesian fertilizer preproduction of the present invention, respectively through the China Agricultural University Shandong * * teach in You Lipo base, Hebei province cotton field test, the performance robust plant, the knot bell is strong, and cotton boll is individual big, compares according to volume increase 19.1%, reaches conspicuous level; Through Liu of academy of agricultural sciences, Henan Province clay fertilizer institute * * senior agronomist in the Li Lao village, Zhenping County, Henan Province peasant household's wheat field test at random, than blank mu volume increase 89.1%, than conventional fertilizer application contrast volume increase 17.7%; Through the senior agronomist Wu of Nanyang City, Henan Province bureau of agriculture * * peasant household's peanut field test at random in Fangcheng County, Henan Province Du Shu town, ripe more consistent than using composite fertilizer's contrast, how big again peanut is, and seed benevolence is full, every mu total really many 283900, volume increase 90% by kernel volume increase 94.3%, is all received unexpected positive effect, be subjected to testing expert and peasant's favorable comment, urgent expectation product of the present invention is put on market early in a large number, is agricultural produce, for increasing peasant income bring good benefit.
