Abstract
The invention discloses a composite fertilizer formula employing zinc sulfate heptahydrate and water-soluble silicate as auxiliary materials. The formula comprises the following components, according to a weight ratio, 800 parts of urea, 12 parts of zinc sulfate heptahydrate, 8 parts of water-soluble silicate, 8 parts of ammonium bicarbonate, 25 parts of nitric acid, 8 parts of water-soluble silicate, 12 parts of ammonium bicarbonate, 25 parts of nitric acid, 38 parts of boron-calcium powder, 25 parts of amino acid, 15 parts of rare earth, 8 parts of a polypeptide controlled-release preparation, and 8 parts of a coating agent. The polypeptide controlled-release preparation comprises the following components, according to a weight ratio, 6 parts of dicyandiamide, 5 parts of hydroquinone, 44 parts of zeolite, and 50 parts of humic acid. The coating agent comprises the following components, according to a weight ratio, 40 parts of sulphur, 40 parts of paraffin, 6 parts of a Bordeaux mixture, and 10 parts of brilliant green. The composite fertilizer is manufactured by the following steps: dissolving urea, zinc sulfate heptahydrate, water-soluble silicate, ammonium bicarbonate, nitric acid, water-soluble silicate, ammonium bicarbonate, nitric acid, boron-calcium powder, amino acid, rare earth, and the polypeptide controlled-release preparation, and performing uniform mixing to obtain a mixture; and granulating the mixture, dissolving the coating agent to coat surfaces of obtained particles, and performing drying.
Description
Technical field
The present invention relates to a kind of compound fertilizer, adopt zinc sulphate heptahydrate and compound fertilizer's formula that water-soluble silicon is adjuvant particularly to a kind of, belong to agrochemical technical field.
Background technology
Fertilizer is to provide the mineral element that one or more plants are required, improves soil property, a class material of level of increasing soil fertility, and is one of the material base of agricultural production.China just has learned that when the Western Zhou Dynasty weeds in field is after rotting, and has the effect promoting maiden cane growth, describes the method for green manuring and the legume method etc. with gramineous crop crop rotation in Important Arts for the People's Welfare in detail；Also refer to and mix with cattle manure urine with crop stem, through the method trampleed on and composting forms fertilizer.In fertilizer practice, " book of victory " there is detailed narration, emphasize use sufficient base manure and mend the spraying fertilizer importance to plant growth.Tang, Song Yihou are along with Oryza sativa L. is in the popularization of the Yangtze river basin, and fertilising experience accumulates day by day, the fertilization principle of " appropriate to the occasion, local product and thing should " thus sum up, namely fertilising should with weather, soil, the change of crop factor and fixed.Along with modern age chemical industry rise and development, various chemical fertilizer are come out one after another.The mid-eighteenth century, phosphorus is divided into straight fertilizer (only containing a kind of nutrient element) and compound fertilizer (containing two or more nutrient element), and the former is such as nitrogenous fertilizer, phosphate fertilizer and potash fertilizer；The binary compound fertilizer of the latter such as nitrogen phosphorus, nitrogen potassium and phosphorus potassium and N P and K NPK.Organic fertilizer includes organic nitrogenous fertilizer, synthetic organic nitrogen fertilizer etc..What China was accustomed to using have people's Animal fecal pollution, green manure, barnyard manure, compost, make compost and biogas manure etc..Organic and inorganic fertilizer and semi-organic fertilizer, be organic fertilizer and the inorganic fertilizer fertilizer by mechanical mixture or chemical reaction.Owing to a kind of fertilizer often has many attribute, except above-mentioned classification, also have other common sorting techniques: 1. can be divided into solid and fluid fertilizer by fertilizer physical state.Solid fertilizer is divided into again powdery and granular fertilizer.Fluid fertilizer is the fertilizer under normal temperature and pressure in liquid condition.2. press the chemical property of fertilizer, chemistry alkalescence acid, chemical and chemically neutral fertilizer can be divided into.3. impact on soil reaction after being absorbed by Plant choosing by fertilizer, can be divided into physiological neutral, physiological alkalinity and physiological acidic fertilizer.4. press the nutrient effectiveness to plant in fertilizer, effect quick-acting, slow and controlled availability fertilizer can be divided into.
Summary of the invention
The present invention proposes and a kind of adopts zinc sulphate heptahydrate and compound fertilizer's formula that water-soluble silicon is adjuvant, there is technological specification, easy and simple to handle, non-environmental-pollution, be suitable for modern industrialization batch production, cheap, easy to use, without soil convert directly can be absorbed by plant, for the plant demand to boron, preventing and treating plant boron deficiency disease, plays growth promoting, takes root, strong sprout, short flower, fruit retention, diseases prevention is degeneration-resistant, the effect that raises productivity and improves the quality.
This invention address that the technical scheme of its technical problem is: a kind of adopt zinc sulphate heptahydrate and compound fertilizer's formula that water-soluble silicon is adjuvant, its formula is: be made up by weight of following component, 800 parts of carbamide, zinc sulphate heptahydrate 12 parts, water-soluble silicon 8 parts, ammonium hydrogen carbonate 8 parts, 25 parts of nitric acid, water-soluble silicon 8 parts, bicarbonate presses 12 parts, 25 parts of nitric acid, boron calcium powder 38 parts, 25 parts of aminoacid, rare earth 15 parts, polypeptide controlled release agent 8 parts, peplos agent 8 parts, described peptide controlled release agent is made up of by weight following component, dicyandiamide 6 parts, hydroquinone 5 parts, 44 parts of zeolite, humic acids 50 parts；Described peplos agent is made up of by weight following component: 40 parts of sulfur, 40 parts of paraffin, Bordeaux mixture 6 parts, light green 10 parts；Step is as follows: by carbamide, zinc sulphate heptahydrate, water-soluble silicon, bicarbonate money, nitric acid, water-soluble silicon, bicarbonate by, nitric acid, boron calcium powder, aminoacid, rare earth and polypeptide controlled release agent dissolve, mix homogeneously, obtain mixture；Mixture is carried out pelletize, then peplos agent is dissolved, be wrapped in the surface of granule, be dried process.
Beneficial effects of the present invention: the present invention has technological specification, easy and simple to handle, non-environmental-pollution, is suitable for modern industrialization batch production, cheap, easy to use, play growth promoting, take root, strong sprout, short flower, fruit retention, diseases prevention is degeneration-resistant, the effect that raises productivity and improves the quality.
Detailed description of the invention
Below in conjunction with instantiation, the invention will be further described.
A kind of adopt zinc sulphate heptahydrate and compound fertilizer's formula that water-soluble silicon is adjuvant, its formula is: be made up by weight of following component, 800 parts of carbamide, zinc sulphate heptahydrate 12 parts, water-soluble silicon 8 parts, ammonium hydrogen carbonate 8 parts, 25 parts of nitric acid, water-soluble silicon 8 parts, bicarbonate by 12 parts, 25 parts of nitric acid, boron calcium powder 38 parts, 25 parts of aminoacid, rare earth 15 parts, polypeptide controlled release agent 8 parts, peplos agent 8 parts, described peptide controlled release agent is made up of by weight following component, dicyandiamide 6 parts, hydroquinone 5 parts, 44 parts of zeolite, humic acids 50 parts；Described peplos agent is made up of by weight following component: 40 parts of sulfur, 40 parts of paraffin, Bordeaux mixture 6 parts, light green 10 parts；Step is as follows: by carbamide, zinc sulphate heptahydrate, water-soluble silicon, bicarbonate money, nitric acid, water-soluble silicon, bicarbonate by, nitric acid, boron calcium powder, aminoacid, rare earth and polypeptide controlled release agent dissolve, mix homogeneously, obtain mixture；Mixture is carried out pelletize, then peplos agent is dissolved, be wrapped in the surface of granule, be dried process.
