Abstract
A release-controlled rare-earth-modified compound fertilizer is prepared through the coating process of release controlling material and chelating-modified rare earth. Its advantages include high yield increased by 6.1-75%, high quality of cropes, low cost and no pollution.
Description
At present, worldwide chemical fertilizer wasting phenomenon is quite serious.It is reported that the utilization ratio of China's nitrogenous fertilizer is about 35%-60%, the utilization ratio of phosphate fertilizer is about 10%-15%, and the utilization ratio of potash fertilizer is about 30%-60%.Chemical fertilizer waste having caused the great attention of countries in the world.
It is many-sided causing the low reason of chemical fertilizer utilization ratio, and the low reason of various nutritive element utilization ratios also is not quite similar, rainwater runs off and soil sandization to cause leaking fertilizer be one of reason wherein.But the rate of release of chemical fertilizer nutritive element is asynchronous with the breeding time of crop, is to cause the low one of the main reasons of chemical fertilizer effective ingredient-use rate.
Now, world Fertilizer is produced and has been entered a new stage, and efficient multi-element composite fertilizer is replacing single low-analysis fertilizer kind in the past.Along with being becoming tight the worldwide energy and raw material supply day, price constantly raises up, and causes the chemical fertilizers production enterprise cost to increase, and the loss phenomenon is serious.Therefore, the control chemical fertilizer nutrient discharges, and makes its speed with the required absorption nutrient of crop growth period synchronous, can either save fertilizer, reduces the fertilizer waste, and the while also helps crop growth.Therefore, sustained release type multi-component composite fertilizer becomes 21 century world Fertilizer industrial expansion direction, and is described as optimal fertilizer of 21 century.
Rare earth is that a class chemical property is very close and very be difficult to isolating element, and the past has the people to think that rare earth is a kind of relatively more rare and native metallic element of picture, and it is not rare in fact, unlike soil yet.They are about 0.106% at the reserves of the earth's crust, surpass common element boron, molybdenum, tin, lead, zinc, cobalt, nickel etc., and its character is typical metal, all has silver-gray metalluster.
Rare earth has Combined Physilogical Effects as little fertilizer in plant growing process.Both can solve soil trace element and lack problem, can utilize rare earth and the amino acid physiological action good again, and promote crop root to grow crop, promote chlorophyll synthetic, improve photosynthesis, promote the activation of enzyme, accelerate material and transform, improve output and the quality of crop.
Yet, directly utilize rare earth to make fertilizer, its crop absorption rate is very low.
Behind amino acid, the humic acids chelating rare earth, be easy to be absorbed by crop.
The chelating amino acids rare earth is divided into aminoacids complex and stings and close rare earth and chelating amino acids rare earth.Because single amino acid chelating rare earth its to the increasing crop yield effect not as good as aminoacids complex, and single amino acid needs extraction separation, therefore than aminoacids complex production cost height.Therefore, use the composite aminoacid chelating rare earth.Useless protein raw materials with recovery is an example, and its manufacturing process is as follows:
The amino acid that obtains above and humic acids chelating rare earth microelement fertilizer and sustained release material mixing is even, make a kind of multiple (mixing) and close the material modified particle coating unit system that sends into and carry out the particle coating.Thereby make sustained release type rare earth modified compound fertilizer.
Used sustained release material is made up of starch, humic acids, amino acid, Sumstar 190, diatomite.Wherein diatomite is as carrier, more than four kinds of compositions as the sustained release material.
Sumstar 190 and starch have swelling property under the effect of soil moisture.Therefore, blood urea nitrogen had adsorptive power.And diatomite has porous, and good water absorption, therefore, can store moisture content, and under the effect of soil moisture, Sumstar 190 and industrial flour are easy to swelling, thereby have improved the adsorptive power to blood urea nitrogen.
Polysaccharide such as starch and Mierocrystalline cellulose natural polymer, its goods are generated carbonic acid gas and water by biological degradation easily in oxygen or oxygen-free process under wet condition.The polymkeric substance of most of microbe degraded is the solublization by hydrolysis.Starch, protein are under the effect of fungi or bacterium excretory enzyme, first hydrolysis oxidative degradation then.Therefore, Sumstar 190 and industrial flour not only can not influence environment, and have the effect of improving the soil.Along with the degraded gradually of Sumstar 190 and industrial flour, be adsorbed and the fertilizer nutrient that is wrapped is discharged gradually, thereby prolonged fertilizer efficiency.
Humic acids is the COMPLEX MIXED fertilizer of the close material of a class formation character, is the alkali extractive of the peat composed of rotten mosses, brown coal or weathered coal.Because it is a kind of hydrophilic colloid, have energy and metal ion exchanged bonded acidic-group, have redox reaction group (perhaps also having some groups of not getting clear) again, thereby be a kind of multi-functional mixture.Humic acids is proved to be already as a plant growth regulators, and can also suppress stomatal aperture, and it is rising that plant is reduced.Therefore, drought resisting, anti-withered.
In addition, amino acid has the chelating this point and sets forth in front.
With Sumstar 190, industry flour, humic acids, aminoacids complex or amino acid add the sustained release material that diatomite makes as carrier by a certain percentage again, the sustained release of why realizing fertilizer nutrient be because industrial flour and Sumstar 190 under the effect of soil moisture and fungi, at first can degrade gradually, generate carbonic acid gas and water, and the fertilizer nutrient of its absorption and parcel is discharged gradually, this process needs about two to four months usually, this process, originally because these two kinds of material degradation speed are slower, therefore, the fertilizer nutrient speed of release is slower, and this is just needing fertilizer nutrient supply less period at the plant growth initial stage.Carrying out along with process of crop growth, particularly near in plant growth mid-term or mid-term for some time after partially, because of crop flowers, fruiting period, the quantity of required various nutrients heightens, and this moment, by controlled-release material, humic acids, amino acid or aminoacids complex, Mierocrystalline cellulose and industrial flour with Sumstar 190 is adsorbed and the various nutrients of fertilizer that coat begin to discharge in a large number, especially with Sumstar 190 and industrial flour and small amount of fibers element etc. because of being in degradative phase, therefore, the quantity of release fertilizer nutrient also can heighten.Like this, the supply plant growth is wanted the quantity of fertilizer nutrient to equate with the quantity of the required absorption nutrient of crop or is close, that is to say, at this moment, the speed that the speed of the fertilizer nutrient that the sustained release material is discharged and plant growth will absorb fertilizer nutrient equates or is close, not only quickened plant growth and sophisticated speed, and it is plentiful and nutritious to help fruit.Arrived the plant growth later stage, fruit is mature on the whole, the amount of the required absorption fertilizer nutrient of crop this moment reduces, and this moment, most of degradation material has been degraded and has been finished in the controlled-release material, materials such as material that remainder is not degraded and humic acids fertilizer nutrient adsorbed and that coat continues to discharge nutrient to crop, is made for thing growth required nutrient of later stage.During to crop harvesting, by controlled-release material absorption, chelating, the fertilizer nutrient overwhelming majority of coating is released.And in whole dispose procedure, be according to crop growth period the demand of fertilizer nutrient uptake rate (or quantity) to be carried out basically.Therefore, realized the sustained release of fertilizer nutrient.
In addition, this controlled-release material and release and release control fertilizer are not only pollution-free in production and use, improve the soil but also have, and improve the soil nutrient structure, and trace element in the balance soil is with the relation of nitrogen phosphorus potassium and organic matter etc.This fertilizer of life-time service can not cause soil compaction, also helps soil granularization on the contrary, strengthens ventilation property, helps soil and preserves nutrient and moisture.
Controlled-release material and chelating rare earth microelement fertilizer by necessarily relatively mixing, all can be made different time of releasing, for the control release type composite fertilizer of Different Crop use.
This control release type rare earth modified compound fertilizer is achieved through the following technical solutions, and illustrates: controlled-release material is by the industrial flour of 20% weight; The Sumstar 190 of 20% weight; The humic acids of 35% weight; The aminoacids complex of 10% weight or amino acid, the Mierocrystalline cellulose of 5% weight, the diatomite of 5% weight (its granularity＜100 orders), mixture all mixes with the composite aminoacid chelating rare earth microelement fertilizer of 5% weight, consumption by composite fertilizer 2% to 5% per ton (weight) adopts cladding process to be coated on the fertiliser granulates surface then, after the drying, sub-sieve obtains finished product.The control release type rare earth modified compound fertilizer that makes thus has following characteristic.
