Description
Technical field
The invention belongs to chemical fertilizer field, and in particular to a kind of composite environment-friendly type chemical fertilizer and preparation method thereof.
Background technology
China is chemical fertilizer production and consumption big country.At present, the chemical fertilizer utilization ratio of China is very low, and nitrogen, phosphorus, potash fertilizer are respectively
25% to 30%, 10% to 25%, 35% to 50%.Current China per hectare fertilizer application amount is up to 240 kilograms, and unit area is applied
Fertilizer amount is 1.6 times of world's average magnitude.China's chemical fertilizer utilization ratio is significantly less than developed country's level, and the service efficiency of chemical fertilizer is in
Downward trend.The national annual nitrogen discharge caused by fertilising is up to 16,500,000 tons, nearly hundred billion yuan of economic loss, it is important that bring from
The aerial serious environmental perspective pollution to underground.Pollution to air is mainly manifested in using chemical fertilizer, chemical fertilizer production or storing
When the direct pollution that causes such as the ammonia, the greenhouse gases that discharge.To polluting mainly in chemical fertilizer under the leaching of water for soil
Generation migration constitutes the main non point source of pollution of body eutrophication so as to flow into rivers, lake or enter underground water.To agricultural production
Product, chemical fertilizer most it is troubling be nitrate accumulation problem.It is grown in using the plant on chemical fertilizer soil, root system can be passed through
Absorb the nitrate in soil.If excessively fertilising, can cause substantial amounts of Nitrate Accumulation in leaf, stem and root, what harm took food
The mankind and livestock.For soil, pollution of the chemical fertilizer to soil, one side heavy dressing easily causes soil hardening；On the other hand
Heavy dressing is likely to result in the reduction and elimination of sensitive biological kind in soil, and destruction agricultural ecological balance influences bio-diversity.
Slow-release controlled-release and it is environment-friendly be Fertilizer development general trend, develop simultaneously application full nutrition release and release control fertilizer be fertilizer
One of final goal of science.Since nineteen forty-two urea-formaldehyde fertilizer obtains patent, the existing rapid progress of slow release fertilizer, in recent years
Controlled Release Fertilizer and some practical application in agricultural production are developed into again.Particularly after the seventies, foreign countries are carried out
Numerous studies, reach tens of kinds with the Slow/Controlled Release Fertilizers that commercial product is sold currently on the market.The U.S., Japan and West Europe
Various countries, are just being directed to applicating modern times technology development Slow or controlled release fertilizer.From late 1960s, China starts slow-release or control-release fertilizer
Research and development of material, and achieve phasic results, release new sustained-controll-release fertiliser successively, can substantially be divided into from principle coating type and
Urinate enzyme (or nitrification) suppressive.Urase (or nitrification) suppressive is relative to coated control release fertilizer with technique is simple, cost is low, ring
The advantages of guarantor, it is only necessary to which a small amount of urease inhibitor or nitrification inhibitor or the two complex are added into nitrogenous fertilizer just can suppress urine
The hydrolysis rate of element, reduces volatilization and the nitrification of ammonium nitrogen, so as to play slow releasing function.However, conventional at present urase (or nitre
Change) inhibitor is generally chemical products, there is that cost is high, the low problem of the feature of environmental protection.
