Description

Rare-earth magnetized compound fertilizer and preparation method thereof

The present invention relates to a kind of rare-earth magnetized Chemical Mixed Fertilizer and preparation method thereof, especially relate to and in plant compound fertilizer, add organic fertilizer, magnetic material and rare earth element, and processing is magnetized in this composite fertilizer and rare earth wherein.

The present fertilizer that farm crop are used, a large amount of is inorganic chemical fertilizer or its composite fertilizer, use the fertilizer efficiency time short, especially exist soil acidification and the critical defect that hardens, in order to increase production, cause fertilizer amount to increase year by year, make soil acidification more serious like this, thereby a kind of vicious cycle occurs with the phenomenon that hardens.Because the chemical fertilizer costliness drops into gradually agriculture production and strengthens, income reduces gradually.In recent years, some magnetic fertilizer occur, be about to permanent-magnet powder and add in the fertilizer, according to soil magnetism and biomagnetism principle, in soil, replenish a part of magnetisable material, be conducive to the formation of crumb structure in the soil and the growth of crop.Therefore in fertilizer, add an amount of magnetic substance and tangible effect of increasing production occurred.But all also there are some shortcomings in disclosed various magnetic fertilizer, for example, disclosed a kind of magnetic fertilizer in the CN90106590.0 patent documentation, wherein magnetisable material derives from flyash, because the Fe that contains in the flyash ₃O ₄Generally be seldom, make this magnetic fertilizer that soil is played the benefit magnetic action, must every mu use 300-700kg flyash.Practice proves that it also is disadvantageous in the soil that a large amount of flyash enters, and easily causes soil desertification.And for example, the CN91100685.0 patent, use be the permanent-magnet ferrite powder, this must make the cost of fertilizer improve.

The objective of the invention is provides a kind of fertilizer efficiency long in order to overcome the shortcoming in the above-mentioned technology, helps alleviating soil acidification and the phenomenon that hardens, and is the magnetic fertilizer of cheap efficient full nutrient.

Rare-earth magnetized compound fertilizer of the present invention is characterized in that, it is made up of fertilizer, chemical fertilizer, the flyash and rare-earth salts, the permanent-magnet powder that contain elements such as Si, Ca, Mg, S, Mn, B, Mo, Zn, Fe.According to the situation of Different Crop to nutrient requirement and soil, press the certain proportion preparation of fertilizer, chemical fertilizer, flyash and rare earth.Above-mentioned fertilizer can be fowl, animal manure fertilizer, barnyard manure, can be human excrement, green manure, plant ash, brown coal etc.Above-mentioned chemical fertilizer refers to nitrogen, phosphorus, potassium chemical fertilizer, such as urea, carbon ammonium, ammonium nitrate, phosphorus ammonium, general calcium, double superhosphate, potassium chloride, potash, precipitated calcium phosphate ... Deng.Above-mentioned flyash also can replace with zeolite.Above-mentioned rare earth is meant muriate or the nitrate that contains lanthanum, cerium, praseodymium, neodymium.Above-mentioned permanent-magnet powder can be the metal permanent-magnet powder, ferrite permanent-magnet powder and rare earth permanent-magnet powder.

Fertilizer of the present invention is composed as follows: expanded chicken pig manure 15-40 part by weight, urea 10-20 part is heavily crossed phosphide calcium 0-12 part, potassium sulfate 0-12 part, flyash 30-55 part, rare earth-iron-boron or nitrate 1-3 part, Fe ₃O ₄Fine iron breeze 1-3 part.Its preparation method is, earlier the chicken pig manure heated 400 ℃ through heating furnace, carries out disinfection, sterilization, deodorizing, drying, expanding treatment; Then by weight proportion, with fertilizer, chemical fertilizer, flyash, rare-earth salts, Fe ₃O ₄Fine iron breeze mixes, and pulverizes, and stirs; In the Chemical Mixed Fertilizer that stirs, add adhesive boron mud, through granulator granulation; At last, with the magnetizing assembly of 2000-6000 oersted magnetic field intensity the magnetization that granulated fertilizer carries out 1-5 second is processed, made the remanent magnetism on granulated fertilizer surface＞1 difficult to understand this treat (Oe).

The present invention is to nutrient demand and different soils composition according to different crops, the needed whole nutrients of preparation plant-growth, satisfy crop to macroelement N, P, K, moderate-element Si, Ca, Mg, S, and the demand of micro-Mn, Mo, Zn, Fe and ultramicro-element rare earth, this meets crop nutrition content trim principle.The present invention namely has fertilizer that inorganic fertilizer is arranged again in composite fertilizer, has the fertile and long-acting advantage of speed.Among the present invention used flyash mainly as in the Chemical Mixed Fertilizer, the component of trace element, the magnetisable material Fe that flyash contains ₃O ₄Be not enough to soil is played the benefit magnetic action, therefore add in addition in the present invention Fe ₃O ₄Fine iron breeze with the consumption that reduces flyash, the effect that improves benefit magnetic, utilizes Fe simultaneously ₃O ₄Fine iron breeze is the most cheap as magnetisable material, has relatively reduced cost with existing various magnetic fertilizer.The present invention also has obvious characteristics to be, adds rare earth element in the Chemical Mixed Fertilizer, and to Chemical Mixed Fertilizer and rare-earth substance wherein in addition strong magnetic magnetization process.Evidence improves the magnetic environment of soil, is conducive to the formation of crumb structure in the soil, increases the gas permeability of soil, and preserve moisture and fertility has stimulated the growth of root system of plant, is conducive to the breeding of Soil Microorganism; And can promote in the soil in the nutrient enzyme and plant the activation of biology enzyme and promote nutrient in the plant absorbing fertilizer, therefore give full play to fertilizer efficiency, promote plant growth, obvious effect of increasing production has appearred.

The present invention once in Jilin Province, 5 areas, east (Tonghua, Huijiang, Siping City, Changchun, Jilin), in the sub-district of 45 representative great soil groups (rice soil, Baijiang soil, meadow soil, atteration), to 5 crop varieties (corn, paddy rice, vegetables, genseng, melon and fruit), 25 different ingredients according to organic magnetized fertilizer, magnetized compound fertilizer carry out the test of two years, obvious effect of increasing production is all arranged, wherein increases in grain production 12%, vegetables volume increase 10-15%.It is more remarkable to use volume increase fruit tree and other industrial crops, and amount of increase in production reaches more than 20%.Because the raw material that this Chemical Mixed Fertilizer adopts mainly is chicken pig manure and flyash, as magnetisable material is Fe ₃O ₄Fine iron breeze, its cost and corresponding composite fertilizer relatively, low 200-600 per ton unit.
