Description
Technical field
The invention belongs to technical field of fertilizer production, and in particular to a kind of controlled availability fertilizer, more particularly to a kind of afforestation
High nutrition environment-protective compound fertilizer formula and preparation method and application.
Background technology
21 century is the development of chemical industry, and the dosage of chemical fertilizer is increased sharply, and long-time service produces soil very big
Influence, be absorbed by crops the 30%-40% that the part utilized also only accounts for sowing amount, remaining is present in soil, Polluted Soil
Earth influences agricultural ecological, the salinization of soil is even directly resulted in when serious.In addition for a long time, it is a large amount of that farmer applies N, P, K partially
Element fertilizer ignores the supplement of middle trace element, causes the nutritional ingredient in soil unbalance so that plant can not effectively absorb profit
With.While planting cost greatly increases, income does not effectively improve but.With the development of high-efficiency agriculture in recent years, spray
It fills, the application of drip irrigation technique, high-content, complete water-soluble Fertilizer application be more and more extensive therefore novel, unique full nutrition
Element water-soluble fertilizer research and development are very urgent.
As more and more enterprises and mechanism participate in the research and development and production of water soluble fertilizer, production technology and original
It is similar in the selection of material.The primary raw material of use has urea, ammonium sulfate, ammonium chloride, monoammonium phosphate, Diammonium phosphate (DAP), phosphoric acid
Potassium dihydrogen, potassium magnesium sulfate, water soluble organic substance and middle trace element etc., these raw materials pass through pulverization process, according to a certain percentage
It is uniformly mixed and corresponding water soluble fertilizer is made.
The water-soluble fertilizer product of prior art mixture is primarily present following problem:(1) appearance is bad.Be mainly reflected in color and luster,
In the inconsistency of granularity.(2) product humidity is big, causes to lump, and influences to use and sell.
Urban landscaping is the infrastructure of urban construction, is the important component of urban construction.It is improving city
City's ecological environment, beautifying city play obvious action and build harmonious fine city in terms of improving people's quality of life
Important embodiment.Good urban landscaping can provide a good rest, entertainment for city dweller, get close to greatly
Place that is natural, meeting people's back to nature hope is the important measures of urban life environment of preserving the ecological environment, improve.Garden
Woods greening with abundant natural resources, with the gardens of artistic conception construction and complete green space system to city with it is full of life,
Grace, and cityscape with their own characteristics.Many countries are using afforestation as the important symbol for weighing urban civilization level.
However, the fertilizer variety for being currently suitable for Nursery Stock growth and handling characteristics compares shortage, mostly with quick-acting
Based on fertilizer.Chinese patent ZL200610161312.6 provides the special fertilizer applied on a kind of nursery stock, it is characterised in that this is specially
It is formed with fertilizer by ammonium sulfate, monoammonium phosphate, calcium superphosphate, potassium sulfate, sulphur, ferrous sulfate, malathion by proportioning mixing,
Raw material weight per distribution ratio is：Ammonium sulfate 40~58%, monoammonium phosphate 8~15%, calcium superphosphate 12~28%, potassium sulfate 15~
25%, sulphur 4~10%, ferrous sulfate 2~4%, malathion 0.02~0.04%.
Chinese patent CN101265137B provides a kind of multifunctional fertilizer dedicated for nursery stock and preparation method thereof, and component is：A groups
Point：Plant ash, root-inducing powder, malathion, B component：Nitrogenous fertilizer, phosphate fertilizer and potash fertilizer；Component C：Acidity regulator.These patent fertilizer
Although having effects that promoting root growth diseases prevention insect prevention, fertilizer efficiency time is short, needs multiple applications, labor intensity is big, time-consuming and laborious, applies fertilizer into
This is higher.
Chinese patent ZL200810014485.4 provides a kind of special-purpose control-release fertilizer for ornamental plant cedar and its preparation side
Method.With sulfur coating urea, thermoplastic resin membrane wrapping urea, thermoplastic resin membrane wrapping composite fertilizer and the potassium chloride of different coating quantities
The components such as composite fertilizer are compounded and are obtained.
Chinese patent CN101928189A (201010264389.2) provide a kind of sustained-release fertilizer for nursery stocks in landscaping and
Preparation and application.Raw material selects different types of Controlled Release Fertilizer：Sulphur increases Molecularly Imprinted Polymer coated carbamide, and 8% thermoplastic is double with thermosetting
Layer coated carbamide, 10% recycling thermoplastic resin membrane wrapping urea, 5% modified epoxy resin integument Diammonium phosphate (DAP) of urea priming coat,
5% modified epoxy resin integument potassium nitrate of urea priming coat, Diammonium phosphate (DAP) are compounded using a variety of coat fertilizer raw materials, according to
Sustained-release fertilizer for nursery stocks in landscaping is made in nutrient element releasing rule in the soil.They are applied by several coated fertilizers
Significant progress is achieved in terms of fertilizer efficiency extension, fertilizer efficiency was up to 2~3 years.But based on a great number of elements such as N, P, K, it is impossible to
Meet the needs of nursery stock centering trace element very well, it is still necessary to individually supplement, increase fertilising cost.
CN101284747A extends its fertilizer efficiency using the complementary advantage of quick-acting fertilizer and organic fertilizer nutrients release speed, but its
Fertilizer efficiency or short generally still needs to apply 1~2 time every year.Chinese patent 201110220288.X discloses a kind of suitable for gardens
Organic-inorganic long-acting fertilizer of greening seedling and preparation method and application.The organic-inorganic long-acting fertilizer by 10~30% it is granular multiple
Hefei, 10~20% coat fertilizer and 55~75% granular organic fertilizer composition.It is more demanding to technology, need setting for highly energy-consuming
It is standby.
Invention content
The shortcomings that in order to overcome the prior art, primary and foremost purpose of the invention was to provide a kind of green suitable for gardens with insufficient
