According to the invention, a particle nitrogen fertilizer is used as a raw material; and the film coating synergistic nitrogen fertilizer is formed by adopting a technology of coating film coating materials such as tung oil, polyvinyl alcohol and the like on the surfaces of large particles by adopting the chelation reaction so as to form a film, wherein the film coating materials are blended through a certain scientific proportioning and are added with the trace elements, zinc sulfate, manganese sulfate, ferrous sulfate, boric acid, borax, ammonium molybdate, magnesium sulfate, a calcium magnesium fertilizer and the like. According to the invention, the validity period of the nitrogen fertilizer is prolonged to 80 to 100 days, the utilization rate of the nitrogen fertilizer is improved by over 30 percent, the yield of the nitrogen fertilizer is increased by 20 to 40 percent and the capacities of resisting drought, cold, diseases and the like of the crops are strengthened.
Description
Technical field
The present invention relates to coated synergistic nitrogenous fertilizer, specifically relate to coating, environmental protection, efficient, multifunctional green synergistic N fertilizer and preparation method thereof.
Background technology
For a long time, China's fertilizer product unreasonable structure, the fertilizer product scientific and technological content is lower.Nutrient proportioning and farm crop nutrient demand amount do not match, nutrient supply period and farm crop nutrient demand phase do not match, and still can not satisfy the requirement that applies fertilizers scientifically.Mostly the fertilizer nutrient of circulation is quick-acting on the market, and especially nitrogen nutrient causes plant recovery of nutrient low through approach such as ammonia-state nitrogen volatilization, nitric nitrogen losses behind the entering soil easily.
For a long time, countries in the world are all in method and the approach trying to explore to improve utilization rate of fertilizer, seek the containment environmental pollution.In exploration and practice, developed country finds that through the fertilizer innovation research slow release fertilizer can improve utilization rate of fertilizer, and the America utilization rate of nitrogen fertilizer reaches 52%, and European utilization rate of nitrogen fertilizer reaches 68%.Therefore, the new and effective fertilizer of development meets following China fertilizer developing direction.
A large amount of losses of chemical fertilizer nutrient not only cause the wasting of resources and financial loss, the more important thing is ecotope is polluted.The environmental friendliness of new-type fertilizer not only can economize on resources, and reduces the peasant and drops into, and help environment protection.
The expert estimates that the year two thousand thirty China's chemical fertilizer demand will reach 6,800 ten thousand tons, increases about 1,500 ten thousand tons of applying quantity of chemical fertilizer again than present needs, and the peasant buys chemical fertilizer need increase by 1,000 hundred million yuan of spendings.And the target that the year two thousand thirty will make the 100000000 hectares of average Fertilization Level in arable land in the whole nation reach 680 kilograms/hectare is difficult to realize that soil, environment will bear immense pressure.Therefore, through the development slow release fertilizer,,, guarantee that the agricultural safety in production of China seems particularly important through raising the efficiency not increasing or increase on a small quantity under the prerequisite of fertilizer amount.
The popularization of new-type fertilizer and use when reducing applying quantity of chemical fertilizer, also will progressively change edatope, improve the quality of farm crop to a certain extent.Urbanization process is quickened the scarcity with the rural laborer, needs the simplification of fertilizer practice, and for the peasant who is in the intensification epoch overcomes difficulties, and the appearance of slow release fertilizer has solved the problem of the between twenty and fifty manpower shortage in rural area well.
After the people such as K.G.Clart of the U.S. in 1948 had synthesized in the world first slowly-releasing condensation fertilizer urea one formaldehyde, the evolution of a diversification had been experienced in the research and development of sustained-controll-release fertiliser.Nineteen sixty mainly was the preliminary study of urea one formaldehyde binding substances slow release fertilizer in the past.The sixties in 20th century, the research and development of slow-release fertilizer have obtained huge progress, and research mainly concentrates on the production and the application facet thereof of urea one formaldehyde condensation products; Paraffin, rosin etc. are as the wrap film aspect; The application of biuret and harm.
To the seventies in 20th century; Research direction is mainly urea one formaldehyde condensation products, polyalkenes etc. as the Wrapped fertilizer film; Mix up other indissoluble things, additive, suppressor factor production slow release fertilizer in the fertilizer, the research aspect that IBDU and positive fourth are pitched two urea condensation compound slow release fertilizers.
Be the age that slow controlled release nitrogenous fertilizer research and development are advanced by leaps and bounds the eighties in 20th century; Slow controlled release nitrogenous fertilizer begins to walk the diversification road; Its research direction also enlarges thereupon; Mainly be to the research as Wrapped fertilizer mould material aspect such as sulphur, Vilaterm, ammonium magnesium phosphate [(NH4) MgPO4H2O], reach research about the bundled slow-releasing fertilizer theoretical model.
To the nineties in 20th century slow-release fertilizer be tending towards ripe, refinement is constantly improved in the research of each side, and exploratory development is carried out in new field, comprising to the research of organic high molecular polymer wrap film decomposition course, the research of absorption slow release fertilizer etc.
At present, the research of sustained-controll-release fertiliser mainly concentrate on the coating novel material research and the novel sustained-controll-release fertiliser prolonged application of research and development, new chemical synthetic slow-release fertilizer synthetic process to research of environmental influence aspect etc.(main reference: the present Research of sustained-controll-release fertiliser and prospect)
Summary of the invention
The objective of the invention is; Coated synergistic nitrogenous fertilizer fertilizer can slowly and enduringly discharge the essential nutritive element of plant-growth; Have characteristics such as nutrient is complete, prescription is reasonable, nuisanceless, long-actingization; Can also reduce because of shower, fixing or nutrient loss that Decomposition causes, prevent that crop early ageing in early stage from taking off fertilizer with the later stage, nutrient release in the regulation release period.Can effectively suppress the conversion rate of ammonium nitrogen, prolong the RT of ammonium nitrogen in soil, increase the validity period of nitrogen manure to nitric nitrogen; Effectively improve the nitrogen manure utilization ratio; Promote plant to nitrogen phosphorus potassium and middle trace elements absorbed utilization, promote root growth, healthy and strong plant; Enhancing crop resistance is improved multifunctional synergistic nitrogenous fertilizer of quality and preparation method thereof.
For solving the problems of the technologies described above; Technical scheme of the present invention is: adopt class coating material, tung oil, vegetables oil, MO, solvent oil, glycerine, Oleum Gossypii semen, plam oil, tea-seed oil, paraffin, PEG 400.; According to following ratio: tung oil 30-50 part; Vegetables oil, MO, solvent oil, glycerine, Oleum Gossypii semen, plam oil, any 25 parts of tea-seed oils, 5 parts, 7 parts PEG 400s of paraffin mix under 40-50 degree heating condition.As class coating material 1.
