Description
Technical field
The invention belongs to coated fertilizer technical fields, and in particular to a kind of to be coated slow, release and release control fertilizer and preparation method thereof.
Background technology
Fertilizer is one of most important means of production of agricultural production, is the material base of agricultural sustainable development.Since 1840
Since year Germanization scholar Liebig JV proposes mineral nutrition of plant theory, fertilizer, which has become, pushes the strong of world agriculture development
Great.However, the rate of release of fertilizer nutrient can not be controlled artificially always, rate of release is too fast, and crop has little time to absorb just
It lost, cause utilization rate of fertilizer low, external utilization rate of nitrogen fertilizer 50%-55%, the country only 30%-35%, serious waste of resources；
Serious water pollution, atmosphere pollution are caused simultaneously, even results in Nitrate in Vegetable severe overweight.Therefore, slow down, control
The dissolving of fertilizer nutrient, rate of release become improve utilization rate of fertilizer, reduce the environmental pollution caused by nutrient loss it is most straight
It connects, one of the most effective ways.
Slow, release and release control fertilizer has many advantages as the substitute products of conventional fertilizers, can greatly improve the utilization of fertilizer
Rate.Slow release fertilizer, its main feature is that after incorporation of fertilizerin the soil, the rate of release for being changed into plant effective state nutrient compares Quick-dissolving fertilizer
It is small.Controlled Release Fertilizer, its main feature is that with reference to modern plants nutrient theory and the new and high technology of control release, and consider crop nutritional need
Rule, by using different coated fertilizers, the acquisition time and burst size of control fertilizer in the soil make its nutrients release pattern
It is required with the need fertilizer of crop growth consistent, is the advanced form of slow release fertilizer.Slow, release and release control fertilizer whether there is coating material by it
Material can be divided into coating (coating) type and non-packet the shapes of the clothes, delay, two major class of Controlled Release Fertilizer.(such as gluing fertilizer carries non-coated slow, Controlled Release Fertilizer
Body fertilizer etc.) various slow, controlled-release material, inhibitor need to be added in fertilizer production or are added in and chemistry can occur with nutrient instead
The substance answered, to reach slow, controlled-release effect, production technology is complicated, investment is big, existing common fertilizer production is difficult to be utilized sets
It is standby, of high cost and slow, controlled-release effect is undesirable, be just gradually coated type delay, Controlled Release Fertilizer substitution.
Coating type Controlled Release Fertilizer is had developed, but because water-soluble resin is dissolved in water with water-soluble resin package nitrogen-phosphorus-potassium compound fertilizer,
It is difficult to reach nutrient controlled-release effect.Ureaformaldehyde release and release control fertilizer is prepared by synthetic method, although controlled-release effect is preferable, technique is answered
The miscellaneous and toxic solvents such as use formaldehyde, are hazardous to the human body.With nonmetallic mineral, vinyl unsaturated monomer, initiator, friendship
Join agent, fertilizer, water-retaining agent etc., by physical mixed, chemical synthesis and coating three phases, have developed water conservation slow-release or control-release fertilizer,
Its production technology is complicated, energy consumption is big, of high cost.The domestic coating type developed, tried out delays at present, Controlled Release Fertilizer majority uses toluene,
The petroleum solvents such as dimethylbenzene, petroleum ether dissolve coating material, and toxicity is higher, to production with being harmful to using personnel health；Have
Make solvent using trichloro ethylene, tetrachloro-ethylene, tetrachloromethane etc., ozone layer can be destroyed, cause atmosphere pollution.
Although slow, release and release control fertilizer has many advantages as the substitute products of conventional fertilizers, fertilizer can be greatly improved
Utilization rate.But generally using harmful, the substance of welding in existing fertilizer coating technology, and production process is answered
Miscellaneous, cost is higher, fertilizer practice is required high, it may occur that the phenomenon that caking influences application, and nutrient is not comprehensive enough, function list
One the problems such as, restricts the development of coated fertilizer.Therefore, development cost is low, simple production process, and environment amenable slow, control
It is one of main direction of fertilizer field research from now on to release fertilizer.
Invention content
Slow, release and release control fertilizer preparation method is coated the purpose of the present invention is to provide a kind of, the preparation method process is simple,
At low cost, low energy consumption, improves resource utilization, environmental protection.
To achieve these goals, used technical solution is：
