Description
Technical field
It is fertilizer, specially a kind of synergist of nitrogenous complex fertilizer the present invention relates to field.
Background technique
Nitrogenous fertilizer is one of maximum agrochemical of current dosage.Outside dephosphorization, potassium and other nutrients, it is also necessary to which nitrogen maintains to plant
The growth and development of object.But after normal fertilising, nitrogenous fertilizer is decomposed quickly in the soil, and nitrogenous fertilizer is largely wasted, farming
The growth cost of object improves, and due to excessively applying fertilizer, causes soil hardening, and certain pollution can be caused to environment.In order to
Improve this situation, inhibits the decomposition of nitrogenous fertilizer, it is general that this drawback is decomposed by addition urease inhibitor solution nitrogenous fertilizer.
Normal-butyl thiophosphoryl triamine (NBPT) can be effectively relieved and contain by being added in nitrogenous fertilizer as urease inhibitor
The decomposition of nitrogenous fertilizer material reduces waste, extends the action time of formulation fertilizer containing nitrogen, improve the service efficiency of formulation fertilizer containing nitrogen.
What is produced at present contains the formulation fertilizer containing nitrogen synergist of normal-butyl thiophosphoryl triamine (NBPT) as urease inhibitor
It is most of be it is powdered, in current production technique for fertilizer, be difficult in conjunction with fertiliser granulates as synergist, liquid synergist
Using obtaining the favor of vast fertilizer production producer.Existing liquid boosting components are more, increase preparation difficulty, patent document
A kind of 1 aqueous compound fertilizer synergistic agent and its preparation and a kind of aqueous compound fertilizer synergy is disclosed using 101298399 B of CN
Agent and its preparation and application, composition include dicyandiamide DCD mass be 50-70%, 4- aminotriazole(ATA) ATC mass be 15-30%,
Normal-butyl thiophosphoryl triamine NBPT mass is 9-20%, sorbitan fatty acid rouge S-80 mass is 3-4% and water, water with
The ratio of above-mentioned four kinds of material total weights is 1: 1-1.5.90~95 DEG C need to be heated in making and using, which causes just
The decomposition of butylthiophosphoric triamide (NBPT), influences the using effect of synergist.A kind of compound fertilizer synergistic agent of document patent 2
And its prepare and disclose a kind of compound fertilizer synergistic agent using 106946632 A of CN, it include normal-butyl thiophosphoryl triamine
(NBPT) 100 parts, 20~60 parts of cosolvent, 20~50 parts of emulsifier, 1~2 part of thickener, 10~20 parts of antifreezing agent, water 150~
200 parts.Component is more, adds heavily to the difficulty of the work in process for preparation, and will certainly have an impact because component is mixed and disorderly to environment.And
And the water that contains of current aqueous synergist will lead to NBPT and be decomposed into invalid component, be applied to containing will cause fertilizer in nitrogen composite fertilizer
Being adhered and agglomerating for material particle, exacerbates the storage problem of formulation fertilizer containing nitrogen, and be difficult to handle.
Summary of the invention
The present invention is intended to provide a kind of nitrogenous compound fertilizer synergistic agent, which can not only inhibit point of formulation fertilizer containing nitrogen
Solution extends fertilizer efficiency, improves the utilization rate of formulation fertilizer containing nitrogen, and component is simple, and it is convenient to prepare, as liquid, more effectively with contain
The mixing application of nitrogenous fertilizer material is easy to operate without causing formulation fertilizer containing nitrogen particle to be adhered, and is conducive to be widely applied, and is formulation fertilizer containing nitrogen
It is modified that effective way is provided.
In order to achieve the above objectives, the technical solution adopted by the present invention is that:
