Description
Technical field
The invention belongs to technical field of fertilizers, particularly a kind of efficient compound fertilizer and preparation method thereof.
Background technology
Traditional chemical fertilizer, especially nitrogenous fertilizer, because the influence of factors such as volatilization, leaching loss and soil fixing, utilization ratio is not high always, and nitrogenous fertilizer this season utilization ratio has only 30%～40%, and phosphate fertilizer this season utilization ratio has only about 10%～20%; Trace element is lower, applies this season and also is difficult to play one's part to the full.Utilization rate of fertilizer is not high, and not only to the increasing of quality and production weak effect of farm crop, economic benefit is low, also may cause a series of ecological environment problem.By industrial approach, producing with high utilization rate, high environmental safety is the efficient compound fertilizer of feature, significant for the development that promotes China's fertilizer industry and pollution-less agriculture.
Humic acids contains multiple groups such as phenolic hydroxyl group, carboxyl, alcoholic extract hydroxyl group, enol base, sulfonic group, amino, quinonyl, carbonyl, methoxyl group.Because the existence of these active groups, acidity, wetting ability, ion exchangeable, complex ability and the higher adsorptive power of humic acids have been determined, quinonyl in the humic acids can suppress soil urease liveness simultaneously, thereby can be hydrolyzed into the ammonium nitrogen process by urease inhibiting effective, reduces ammonia loss by volatilization.These characteristics of humic acids make it to become a kind of good fertilizer synergistic agent, mix with chemical fertilizer and use, and can obviously improve the utilization ratio of various fertilizer nutrients.
The castor-oil plant dregs of rice contain rich in protein and small molecules amino acid.Protein is the main food source of soil microorganisms, thereby uses the castor-oil plant dregs of rice in the soil and can improve soil microbial activities, quickens soil material and energy cycle, improves soil productivity.Small molecules amino acid in the castor-oil plant dregs of rice can directly be absorbed by crop simultaneously, improves the agricultural production quality.
Yet the comprehensive utilization humic acids and the castor-oil plant dregs of rice improve the utilization ratio of various fertilizer nutrients and do not appear in the newspapers as yet.
Summary of the invention
At the existing low problem of chemical fertilizer plant recovery of nutrient, the invention provides and a kind ofly can improve the utilization rate of fertilizer efficient compound fertilizer that improves quality of agricultural product and preparation method thereof of improving the soil again.
Technical solution of the present invention is as follows:
Efficient compound fertilizer of the present invention is formed by activation weathered coal, the castor-oil plant dregs of rice, chemical fertilizer and clay mixing granulation, example is counted by weight percentage, its concrete composition is: activation weathered coal 10%～25%, the castor-oil plant dregs of rice 5%～10%, urea 10%～22%, monoammonium phosphate 18%～30%, Repone K 0～25%, vitriolate of tartar 0～23, trace element 0～3%, magnesia 0～1%, clay 8%～12%;
Described trace element is one of Zn, B, Mn, Fe, Mo or its combination; By weight percentage, described activation weathered coal contains the salt of wormwood of weathered coal butt weight 6%～15% and the urea of weathered coal butt weight 5%～20%.
The concrete activation method of described activation weathered coal is: weathered coal is crushed to≤60 orders, getting the salt of wormwood of weathered coal butt weight 6%～15% and the urea of weathered coal butt weight 5%～20% is dissolved in the water of weathered coal butt weight 50%～70%, the solution of making is heated to 50～80 ℃, then with weathering coal dust and above-mentioned solution thorough mixing, stir, stacked at normal temperatures 24～72 hours, drying obtains containing the black activation weathered coal of potassium humate and humic urea, drying requires water content≤20%, and drying temperature is lower than 120 ℃.
The described castor-oil plant dregs of rice are made of the castor seeds residue that squeezes behind the Viscotrol C, through micronizing, it are crushed to≤200 orders.
Adopt the mixing granulation technology, described raw material is mixed in proportion, its weight percent is: activation weathered coal 10%～25%, the castor-oil plant dregs of rice 5%～10%, urea 10%～22%, monoammonium phosphate 12%～30%, Repone K 0～25%, vitriolate of tartar 0～23%, trace element (Zn, B, Mn, Fe, Mo) 0～3%, magnesia 0～1%, clay 8%～12%.
Inventive principle:
Active group in the humic acid has stronger absorption sequestering power to fertilizer nutrient, and the nutrient that is adsorbed chelating is slowly discharged, and reduces its dead loss and leaching loss in soil, increases its crop specific absorption; Simultaneously the quinonyl in the humic acids can suppress soil urease liveness, thereby can effectively delay hydrolysis of urea and become the ammonium nitrogen process, reduces ammonia loss by volatilization.
Utilize salt of wormwood and urea that weathered coal is carried out activation treatment, can generate potassium humate and humic acid urea, part humic acid macromolecular structure can be destroyed simultaneously, generate xanthohumic acid, and increase humic acid ion exchangeable, complex ability and adsorptive power with physiologically active.Humic acid after the activation not only itself can provide plant growth required nutrient, promotes plant growth, and has improved the synergism to chemical fertilizer.
The castor-oil plant dregs of rice are carried out micronizing, can increase the adsorptive power of the castor-oil plant dregs of rice, promote the biological degradation of the castor-oil plant dregs of rice simultaneously, improve soil microbial activities, quicken soil material and energy cycle, improve soil productivity fertilizer nutrient; In addition, the castor-oil plant dregs of rice are through micronizing, and the amino acid whose content of its active small molecular also increases thereupon, more helps crop and absorbs.
Compare with other common composite fertilizer, major advantage of the present invention is:
1. significantly improve the fertilizer nutrient utilization ratio.Can improve nitrogen use efficiency 10%～30%, improve phosphorus utilization 5%～10%, improve potassium utilization ratio about 5%, and micro-utilization ratio in significantly improving.
2. can satisfy and supply plant-growth required multiple nutrient, the conditioning plant-growth improves crop yield and quality.The present invention contains the required nitrogen of plant growth, phosphorus, potassium and multiple middle trace element, and contains protein, amino acid and physiologically active substances such as various other small molecular organic acid and polysaccharide; Potassium humate and humic acid urea can quicken crop metabolism simultaneously, the conditioning plant-growth.
3. the physical behavior of improving the soil can promote the formation of healthy soil organisms chain, reduces and prevents deriving of disease and pest, for good ecological organic condition is set up in plant-growth.
