Abstract
The invention discloses a colloidal suspension agent for nitrogen fertilizer synergism, which is prepared from 2-chlorine-6-nitrapyrin, an emulsifier, calcium lignosulphonate, white carbon black, xanthan gum, N,N-dimethylformamide and water in a certain proportion. The nitrogen fertilizer can be sprayed to the particle surface after being screened by using the colloidal suspension agent along with good attachment effect, so that addition of the colloidal suspension agent before nitrogen fertilizer granulation is avoided, so that waste is reduced, and production cost is reduced; and the defect that 2-chloride-6-trichloromethylpyridine is slightly soluble is overcome, so that the colloidal suspension agent can be applied to nitrogen-containing water-soluble fertilizer.
Description
Technical field
The present invention relates to a kind of compsn, relate in particular to and a kind ofly be used for nitrogenous fertilizer synergic suspension concentrate and making stable Application in Fertilizer.
Background technology
The chemical fertilizer usage quantity of China in 2010 ranks first in the world more than 100,000,000 tons, but the utilization ratio of chemical fertilizer is merely 30%-35% then; Utilization rate of nitrogen fertilizer 30%-35% wherein; Phosphate fertilizer 10%-20%, potash fertilizer 40%-50% is far below developed country's level (50%-60%).The economic worth of China's loss of nitrogen fertilizer amount in 2011 is 60,000,000,000-80,000,000,000.The nitrogenous fertilizer that loses is serious day by day to the detrimentally affect of underground water body, surperficial water body and atmospheric environment.Because the conversion rate of nitrogen in soil is too fast, phosphorus element and potassium element are very soon by soil fixing, and crop can not absorb for a long time, also need repeatedly topdress for the crop later stage.The utilization ratio that improves chemical fertilizer has become the task of top priority.The problem that utilization rate of fertilizer is low in order to solve, fertilizer efficiency period is short has successively worked out urea formaldehyde sustained-release fertilizer, stable fertilizer both at home and abroad, coating class controlled release is fertile and relevant perhaps derived product.Wherein urea formaldehyde and coating series products are because cost is high, and complex process is prone to bring defectives such as secondary pollution, and it is slower to promote development at present.Stability fertilizer be meant in nitrogenous fertilizer or nitrogen fertilizer production or add in using urease inhibitor with (or) one type of new type nitrogen fertilizer kind of nitrification inhibitor.Urease inhibitor and nitrification inhibitor can be controlled amidonitrogen respectively to the conversion to nitric nitrogen of ammonium nitrogen and ammonium nitrogen, and effect is remarkable, and cost is lower, and the use prospect is very big.N-serve has passed through strict laboratory toxicological test, land for growing field crops long run test and transformation period check, when having effective inhibition effect, edatope is not had detrimentally affect, is a kind of nitrification inhibitor safely and reliably.But the N-serve vp is higher; When surpassing 70 ℃, temperature is prone to distillation; Therefore when directly adding to before the granulation of nitrogenous fertilizer according to ordinary method, through oven dry or follow the pyritous production process can be lossy, thereby cause waste to increase production cost.
Water-soluble fertilizer has obtained application more and more widely now, and water-soluble fertilizer has the branch of solid water-soluble fertilizer and liquid water-soluble fertilizer.The solid water-soluble fertilizer is used water dissolution more all with solid form production or deposit during use; The liquid water-soluble fertilizer is then with liquid form production or deposit.In order to make stable water-soluble fertilizer; Can in solid water-soluble fertilizer dissolution process or in the liquid water-soluble fertilizer course of processing or the dissolution process, add N-serve; But because the solubleness of N-serve in water is limited; The use that makes it in water-soluble fertilizer is restricted, and effect is unsatisfactory.
Summary of the invention
Technical problem to be solved by this invention provides a kind of nitrogenous fertilizer synergic suspension concentrate that is used for, and it is used to prepare stable fertilizer, can avoid the waste loss of N-serve in application process, reduces production costs; Can also be used to make stable water-soluble fertilizer, increase the solubleness of N-serve in water greatly, improve the result of use of fertilizer.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
A kind of nitrogenous fertilizer synergic suspension concentrate that is used for; It is characterized in that each composition weight proportioning is a N-serve: emulsifying agent: calcium lignin sulphonate: WHITE CARBON BLACK: XG 550: N, dinethylformamide: water=100: 20～100: 1～5: 20～100: 1～5: 2～10: 100～500.
Technique scheme can be optimized, and promptly each composition weight proportioning is a N-serve: emulsifying agent: calcium lignin sulphonate: WHITE CARBON BLACK: XG 550: N, dinethylformamide: water=100: 50: 3: 50: 2: 5: 290.
Said emulsifying agent is 0613-X, is the commercial goods, can buy acquisition.
Another technical problem to be solved by this invention provides the application of this suspension concentrate in making stable fertilizer or stable water-soluble fertilizer, and the technical scheme of taking is:
Be used for nitrogenous fertilizer synergic suspension concentrate and making stable Application in Fertilizer, it is characterized in that with after the nitrogenous fertilizer screening said suspension concentrate being sprayed on the nitrogenous fertilizer particle surface, the weight ratio of suspension concentrate and nitrogenous fertilizer is 1: 200～1000, preferred 1: 300.
Aforementioned nitrogenous fertilizer is urea, ammonium nitrogenous fertilizer or is compound (mixing) fertilizer that raw material is made with urea and/or ammonium nitrogenous fertilizer.
Perhaps; Be used for nitrogenous fertilizer synergic suspension concentrate in the application of making stable water-soluble fertilizer; It is characterized in that said suspension concentrate is added in the application dissolution process of solid water-soluble fertilizer; In the course of processing of liquid water-soluble fertilizer or use in the dissolution process and add, the weight ratio of suspension concentrate and solid water-soluble fertilizer or liquid water-soluble fertilizer is 1: 80～2000, preferred 1: 450.
Said solid water-soluble fertilizer or liquid water-soluble fertilizer are with urea or/and ammonium nitrogenous fertilizer is the water-soluble fertilizer that nitrogenous source is made.
The present invention is through being made into N-serve suspension concentrate and controlling each set of dispense ratio; Suspension concentrate can be sprayed on the nitrogenous fertilizer after the nitrogen fertilizer screening again, and adhesion effect is good, has avoided before the nitrogenous fertilizer granulation, adding; Both reduced waste; Protected operating environment again, be applied in the nitrogenous water-soluble fertilizer, solved N-serve in a water-soluble sl. sol. difficult problem; And make the various material environmentally safes that suspension concentrate uses, help environment protection.
