Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of gardens slow release fertilizer.
Background technique
China soil is vast, and cultivated area accounts for global 7%, but populous so that per capita area of cultivated farmland is seldom,
The population in the world 22% is supported by the arable land for accounting for the world 7%, and as the process of urbanization causes cultivated area to tail off,
Therefore higher and higher, and the agriculture effect increased production dependent on chemical fertilizer is required to the agricultural volume increase of reduction cultivated area increasingly.It passes
System chemistry faces two large problems in agricultural production use process: first is that fertilizer amount is big, utilization rate is low, China's this season fertilizer benefit
It is 30-35%, phosphate fertilizer utilization efficiency 10-25%, potash fertilizer 35%-50% with rate nitrogenous fertilizer；Second is that chemical fertilizer application is unreasonable, at present
The chemical fertilizer application in China is still based on quick action fertilizer by several times application, and utilization rate is low, and the fertilizer efficiency period is short, and at high cost, pollutes ring
Border.Therefore, the effect for how improving utilization rate of fertilizer, giving full play to fertilizer to plant has China's agricultural sustainable development
Major and immediate significance.Slow release fertilizer is also known as slow-release fertilizer or release and release control fertilizer.Compound in its fertilizer containing nutrient is in soil
Middle rate of release is slow or the available a degree of control of nutrient releasing speed is for the utilization of crop constant absorption.At present
Slow release fertilizer is divided into four major class: synthesis class slightly soluble slow release fertilizer, carrier slow release fertilizer, matrix composite and be glued slow release fertilizer and
Coating coating type slow release fertilizer, but the country is based on coating coating type slow release fertilizer at present, since its slow release effect is preferably general
All over receiving.
Patent 201410130689.X disclose it is a kind of with isobutene pitch two ureas be coated slow release fertilizer and its preparation side
Method, material quality number are as follows: isobutene pitches two ureas and is coated 5~15 parts of potassium chloride, and 6~18 parts of granular urea, resin is coated
20~45 parts of urea, 15~25 parts of Diammonium phosphate (DAP), 10~20 parts of granule potassium chloride, which is coated compared to resin and sulphur
Coating, will not cause secondary pollution to soil, will not destroy soil texture, preserve the ecological environment.But the slow release fertilizer needs
The nutrient that dish after two ureas are completely dissolved starts release kernel, the in this way plant for needing nutrient early period are pitched in isobutene, it appears
Some effect are insufficient, in addition, the effective component of the slow release fertilizer is traditional N P and K, for microelement additive amount very
It is few, it is also necessary to apply fertilizer again, increase fertilising workload and fertilising cost.
Patent 201610749601.1 discloses a kind of preparation method of ureaformaldehyde slow release fertilizer containing composite bacteria agent, the party
Nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, ureaformaldehyde powder and auxiliary material are added in pelletizing drum according to certain mass ratio and are granulated by method, drying, cold
But and after screening, ureaformaldehyde slow release fertilizer is obtained, in pack roller, package oil and composite bacteria agent are injected to ureaformaldehyde slow release fertilizer
Surface, obtains the ureaformaldehyde slow release fertilizer containing composite bacteria agent, the slow release fertilizer using composite bacteria agent good water solubility and be easy to plant
Object is absorbed and utilized, and the growth regulating and induction resistance mechanism that can participate in plant promote the growth of plant, improves plant to bad
The resistance of environment and pest and disease damage.But the slow release fertilizer of the composite bacteria agent in the higher soil for putting into saline and alkaline degree when,
It is easy to cause composite bacteria agent not adapt to environment and mortality, in addition, the package oil of the slow release fertilizer is easily by water-soluble and micro- life
Object decomposes, and on the one hand causes the slow releasing function of ureaformaldehyde slow release fertilizer to reduce, on the other hand leads to composite bacteria agent and ureaformaldehyde slow-release fertilizer
Material directly contact keeps composite bacteria agent dead, so that the slow release fertilizer effect reduces, plant regular period nutritional ingredient is caused to be supplied
Deficiency needs to apply fertilizer again.
Patent 201410656449.3 discloses a kind of preparation method of dedicated carbon-base slow release fertilizer of wheat, including following step
It is rapid: by 50~65 parts of polyethylene wax, 5~10 parts of organic acid, 5~12 parts of starch, 5~10 parts of sodium bicarbonate, alcohols solvent 20~
30 parts of obtained carbon microspheres, by 20~30 parts of carbon microspheres and urea, 10~20 parts of ammonium phosphate, 10~20 parts of ammonium sulfate, water 100~
150 parts of obtained fertilizer matrixes, by 5~7 parts of cashew nut oil, 10~12 parts of hexa, 4~8 parts of polyalcohol and polyisocyanic acid
Coating agent is wrapped on fertilizer matrix and carbon-base slow release fertilizer is made by 2~3 parts of obtained coating agents of ester.The slow release fertilizer improves
The slow release effect of fertilizer has achieved the effect that volume increase.But it is done in the slow release fertilizer using hexa and polyisocyanates
Coating membrane, hexa have corrosivity, cause dermatitis after contacting human body and surprise is itched, and is inflammable, toxic by thermally decomposing
Nitrogen oxide flue gas, polyisocyanates volatility, irritation and toxicity are all bigger, in process of production not only to human injury
It is larger, it is higher for production safety requirement, and also the influence after fertilising for root system of plant is also very big, coating membrane volatilization degradation
Afterwards, it so that slow-release capability reduces, causes effective component release rapidly, the effect that plant constant absorption utilizes is not achieved.
Therefore it develops and application slow release fertilizer, reduces the solution rate of fertilizer, make the fertilizer be successively in slow course of dissolution
Crop provides effective component, injures crop seed, seedling or leaf of burning etc. because local concentration is excessively high when preventing from largely applying
Adverse consequences, to reduce the fertilising period, reduces cost, reaches eco-friendly and guarantor to reach raising chemical fertilizer utilization ratio
Demonstrate,prove the purpose of crop yield.
