A kind of composite coated fertilizer of multielement that contains mineral powder and preparation method thereof
Technical field
The present invention relates to fertilizer field, particularly a kind of composite coated fertilizer of multielement that contains mineral powder and preparation method thereof.
Background technology
Plant is at a large amount of its Fast Growth of Nutrients uptake of necessary for growth, and different soil has a certain impact to the growth of crop, and this just need to effectively improve soil. The fertilizer of existing improvement soil just can be seen the impact of fertilizer on crops, can not reach effective improvement to soil. Most of soil causes soil compaction owing to using chemical fertilizer, and lean soil, because fertilising is unreasonable, is not effectively improved the soil, thereby caused not having harvest or in poor harvest. Different Crop is due to different habits, different growth phase, all not identical to the demand of fertilizer, therefore, need to, in conjunction with different crop varieties, study different fertilizer, be starved of, to improve soil, improve quality and the speed of growth of crop, increase corps nutrient and be worth with health care.
Summary of the invention
The object of this invention is to provide
In order to realize object of the present invention, the present invention passes through following scheme implementation:
The composite coated fertilizer of multielement that contains mineral powder, is made up of the raw material of following weight portion: medical stone 12-14, bentonite 9-11, zeolite 8-10, diatomite in powder 8-10, ferrous sulfate 1-2, borax 1-2, copper sulphate 1-2, manganese sulfate 1-2, active carbon 7-9, cupric oxide 1-2, humic acid 3-4, plant ash 11-12, urea 30-33, potassium nitrate 14-19, ammonium molybdate 1-2, sodium hydrogen phosphate 18-21, soil conditioner 7-9, water are appropriate;
Described soil conditioner is made up of the raw material of following weight portion: Iron-ore Slag 10-20, nano-carbon powder 1-2, sodium metasilicate 4-5, anilinomethyl triethoxysilane 17-19, yeast selenium 3-4, copper sulphate 2-3, zinc gluconate 2-3, magnesium chloride 1-2, ammonium molybdate 2-3, boric acid 1-2, double pentaerythritol methacrylate 4-6, vinegar 30-40, ferrous sulfate 2-3, eucalyptus oil 1-2, hydroxyethylcellulose 5-6, jade powder 4-5,3-aminopropyl trimethoxysilane 2-3; Preparation method is first by anilinomethyl triethoxysilane, double pentaerythritol methacrylate and Iron-ore Slag, nano-carbon powder, eucalyptus oil, hydroxyethylcellulose, jade powder, 3-aminopropyl trimethoxysilane mixing and stirring, be heated to 65 DEG C-75 DEG C, form mixture; Again all the other residual components are mixed, fully stir and form vinegar mixed liquor; Mixture is mixed to high speed dispersion form slurry and get final product with vinegar mixed liquor.
The composite coated fertilizer of a kind of multielement that contains mineral powder of the present invention, made by following concrete steps:
(1) after ferrous sulfate, borax, copper sulphate, manganese sulfate, cupric oxide, potassium nitrate, ammonium molybdate, sodium hydrogen phosphate are mixed, add appropriate warm water, mix and add soil conditioner, continue to stir, high speed dispersion obtains after slurry, concentrate drying, granulation;
(2) all the other residual components except urea are mixed, concentrate drying, pulverizes granulation;
(3) particle in particle in step (1) and step (2) is mixed to the drum-type mixing granulation machine of putting into; the urea of spraying-and-heating melting outside hybrid particles; make hybrid particles outer surface form coating as far as possible uniformly, 65 DEG C of-75 DEG C of heated-air dryings, room temperature wind is cooling and get final product.
The invention has the beneficial effects as follows: the present invention contains the multiple composition of ores such as medical stone, bentonite, there is effect of preserve moisture and fertility, add soil conditioner, there is synergy, promote plant to absorb the effect of nutrition; The present invention adopts urea coated, and fertilizer slow release is effective, and fertility is lasting, is applied to crop, can increase substantially the quality of agricultural product, and long-term use can improve soil alkaline, situation hardens.
Specific embodiments
Below by instantiation, the present invention is described in detail.
The composite coated fertilizer of multielement that contains mineral powder, by following weight portion (kilogram) raw material make: medical stone 12, bentonite 9, zeolite 8, diatomite in powder 8, ferrous sulfate 1, borax 1, copper sulphate 1, manganese sulfate 1, active carbon 7, cupric oxide 1, humic acid 3, plant ash 11, urea 30, potassium nitrate 14, ammonium molybdate 1, sodium hydrogen phosphate 18, soil conditioner 7, water are appropriate;
Described soil conditioner by following weight portion (kilogram) raw material make: Iron-ore Slag 10, nano-carbon powder 1, sodium metasilicate 4, anilinomethyl triethoxysilane 17, yeast selenium 3, copper sulphate 2, zinc gluconate 2, magnesium chloride 1, ammonium molybdate 2, boric acid 1, double pentaerythritol methacrylate 4, vinegar 30, ferrous sulfate 2, eucalyptus oil 1, hydroxyethylcellulose 5, jade powder 4,3-aminopropyl trimethoxysilane 2; Preparation method is first by anilinomethyl triethoxysilane, double pentaerythritol methacrylate and Iron-ore Slag, nano-carbon powder, eucalyptus oil, hydroxyethylcellulose, jade powder, 3-aminopropyl trimethoxysilane mixing and stirring, be heated to 65 DEG C-75 DEG C, form mixture; Again all the other residual components are mixed, fully stir and form vinegar mixed liquor; Mixture is mixed to high speed dispersion form slurry and get final product with vinegar mixed liquor.
The composite coated fertilizer of a kind of multielement that contains mineral powder of the present invention, made by following concrete steps:
(1) after ferrous sulfate, borax, copper sulphate, manganese sulfate, cupric oxide, potassium nitrate, ammonium molybdate, sodium hydrogen phosphate are mixed, add appropriate warm water, mix and add soil conditioner, continue to stir, high speed dispersion obtains after slurry, concentrate drying, granulation;
