Description
Technical field
The invention belongs to new-type fertilizer field, in particular it relates to a kind of prepare containing microcapsule-type fertilizer synergist answer
The method in Hefei, i.e. add microcapsule-type fertilizer synergist during fusion method produces compound fertilizer, thus it is fertile to prepare stability
The method of material.Moreover, it relates to the compound fertilizer containing microcapsule-type fertilizer synergist prepared by this method and
Its application and application process.
Background technology
Nitrogen element, as in the necessary nutrient of plant, has extremely important effect.As the important sources of nitrogenous fertilizer,
Amidonitrogen and ammonium nitrogen will experience ammonium nitrogen in soil and be oxidized to nitrite nitrogen, is aoxidized by nitrobacteria further
Become the process of nitrate nitrogen.According to presently disclosed research, the amidonitrogen entering soil changed into ammonium nitrogen, ammonium state at 3-7 days
Nitrogen had the nitrogen transformation of 80% to become nitrate nitrogen in 15-20 days.Nitrate nitrogen is difficult to be adsorbed in soil, it is easy to leaching runs off,
Cause overall utilization rate of nitrogen fertilizer low, be attended by the discharge of greenhouse gases simultaneously.
Suppress the ammonium nitrogen conversion to nitrate nitrogen by adding nitrification inhibitor, be raising nitrogen fertilizer use in fertilizer industry
The effective means of rate, N-serve is the active component the highest to nitrobacteria suppression ratio of current commercialization,
Many documents are had to report relevant dosage form and the application process in fertilizer.
CN102976857 discloses by being joined by N-serve in organic solvent and anticaking agent,
Then the method adding carbamide.CN103524272 discloses the N-serve method by high-tower granulation
Joining the method in compound fertilizer, both the above method is to be added directly in carbamide or compound fertilizer by active component, exists
The volatile and labile problem of active component.
CN102249817 discloses the form that N-serve is prepared as cream, but the application of the method
Scope is less, and environment is adversely affected by the solvent in cream.
US20080176745 and US20090227458 of Tao Shi benefit agriculture discloses and is prepared by N-serve
The method becoming micro-capsule suspension (that is, microcapsule-type fertilizer synergist), has prepared commercial prod Entrench (Chinese
Name: companion's energy), this product is directly used in field and uses or the mixed use of bucket, and the lasting period in soil was up to 60 days.
CN104262065 discloses and by extruder grain method, the micro-capsule suspension product of commercialization is added the side in compound fertilizer
Method, its preparation method is first to be mixed with part fertilizer material by spray process by micro-capsule suspension product, the most again with surplus
Remaining fertilizer material mixing, obtains complex fertilizer product by the method for extruder grain.The synergist of microcapsule-type is disperseed by the method
In compound fertilizer, but in production technology, add spray process, and then add equipment and running cost, and squeezing and pressing method produces
Compound fertilizer also has that production efficiency is relatively low, stock dispersion is uneven, the irregular serious problems of fertiliser granulates.
In current and foreseeable future, still based on solid fertilizer in Term Fertilization.Develop high-quality, environmental protection and
Efficient solid composite fertilizer technology is promotion agricultural development, realizes the important leverage of Reducing amount of chemical fertilizer applied potentiation, is also art technology
Personnel have been working hard the target going realizing.
