Description
Technical field
The present invention relates to a kind of nitrogen potassium dressing fertilizer and preparation thereof, belong to the agricultural fertilizer production technical field with slow release effect.
Background technology
The arable land of China accounts for 7% of the world, has but used the chemical fertilizer that accounts for the world about 35%, and fertilizer amount occupies first place in the world, and chemical fertilizer utilization ratio is low to be the subject matter that faces.Nitrogenous fertilizer is applied to very easily loss behind the soil, loss by way of drip washing, gas loss and fixing are arranged, the utilization ratio of nitrogenous fertilizer has only about 30%, a large amount of losses.The annual nitrogenous fertilizer by drip washing and volatilization loss of China causes huge waste at 1200 ~ 1,400 ten thousand tons.Potash fertilizer also can produce loss by drip washing and runoff in soil, its utilization ratio is high slightly, also has only about 35%.Fertilizer loss is except that causing waste, and serious environment pollution reduces quality of agricultural product simultaneously.Improve utilization rate of fertilizer, to become extensive concern emphasis problem.
Topdressing is the important component part of crop fertilization, and topdressing accounts for more than 50% in whole fertilizer amount, and the technology of topdressing is had more deep research, and method is varied.But the research and development to the kind of topdressing are not enough, and the special use kind of topdressing lacks very much.People always wish once to use base manure to solve the fertilizer demand of crop whole growing, realize the cost high investment often of this imagination, repay very little, usage at fertilizer, Application and Development is to realize that fertilizer efficiently utilizes in topdressing of different growing stages crop, reduces the effective way that drops into.
Existing topdressing generally adopts direct blending production of chemical fertilizer raw material or peasant directly to be used in the field, and the fertilizer dissolution rate is fast, causes damage easily.Adopt common composite fertilizer as the less pertinence of topdressing, nitrogen phosphoris and potassium fertilizer ratio is inharmonious, and the release rate of fertilizer is improper.Existing Chinese patent file CN1398828 (02126643.3) has announced the compound production technology of topdressing of a kind of humic acid, this patented technology does not have to solve topdresses dissolving according to the problem of crop different mining with different release rate fertilizer, its release rate is very fast, and utilization rate of fertilizer does not guarantee.The patent of sustained-controll-release fertiliser is a lot, as Chinese patent file CN1227208 (98113795.4), CN1990431 (200510136714.6) and CN100340531C (20050051250.9) etc. all is not only can topdress but also can make the kind of base manure, all contain the phosphorus element in the fertilizer, phosphate fertilizer generally applies with the base manure form in the actual production, and only suitable nitrogen potash fertilizer topdresses.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of nitrogen potassium dressing fertilizer with slow release effect and preparation method thereof is provided.
The present invention also provides the application of this fertilizer, especially the application on agricultural.
Slow-release nitrogen potassium dressing fertilizer of the present invention, raw material is as follows, is weight part,
The A group: 10～90 parts of fertilizer slow release materials, wherein, 10～20 parts of humic acid, 7～15 parts in xylogen, 0.3～0.7 part of Dyhard RU 100;
The B group: 30～100 parts of soluble nitrogen potassium fertilizers, wherein, the weight ratio of nitrogenous fertilizer and potash fertilizer is (36～42): (20～29).
In the described soluble nitrogen potassium fertilizer, solubility nitrogenous fertilizer is selected from one of urea, ammonium sulfate or combination, and solubility potash fertilizer is selected from one of saltpetre, Repone K, vitriolate of tartar or combination.
Described humic acid is the following common commercially available humic acid of moisture content 10%wt, preferred mistake 80 mesh sieves,
Described xylogen is the following paper mill of a moisture content 15%wt tankage xylogen, preferred mistake 80 mesh sieves.If xylogen moisture content of raw material height can dry or dry, if standby after fineness should be pulverized inadequately.
Described Dyhard RU 100 is crossed 80 mesh sieves, and commercially available product gets final product.
B group chemical fertilizer raw material is conventional agricultural fertilizer, 80 mesh sieves, and commercially available product gets final product.
The preparation method of slow-release nitrogen potassium dressing fertilizer of the present invention, adopt one of following:
1, B is organized soluble nitrogen potash fertilizer raw material and pulverize, cross 80 mesh sieves, organize fertilizer slow release material uniform mixing in proportion with A, the finished product after the screening can be packed to detect and dispatch from the factory.Perhaps
2, B is organized soluble nitrogen potash fertilizer raw material and pulverize, cross 80 mesh sieves, organize fertilizer slow release material uniform mixing in proportion, add the granulation tackiness agent, adopt rotating disk or drum granulating, dry after the granulation, cool off then, sieve with A.Finished product after the screening can be packed to detect and dispatch from the factory.
Described granulation is crossed 80 mesh sieves with preferred wilkinite of tackiness agent or attapulgite.Purchase on the market and get final product, consumption is by prior art.
It is main raw material that fertilizer of the present invention adopts humic acid, xylogen, nitrogen potassium fertilizer, can be used for all soil types and farm crop, effect the best on vegetables, fruit, it can improve Soil structure, improve the soil water-reataining fertilizer-keeping performance, has better volume increase and improves the effect of crop quality.
Slow-release nitrogen potassium dressing fertilizer of the present invention is as the application of soil improvement agent.Preferably use as dressing fertilizer, concrete grammar is as follows:
In the field fertilizer being ditched near crop root imposes, and consumption uses 1～2 time in the crop growth period at every turn at 150kg～450kg/ha.
The field effect:
A large number of experiments show that the slow release type nitrogen potassium result of use of topdressing is obvious, have the effect that makes crop significantly increase production, improve quality and improve the soil.A plurality of tests of carrying out on facilities vegetable, outdoor vegetable, fruit tree and field crop show, use slow release type nitrogen potassium to topdress can to make tomato production promoting 6%～15% with using to compare with the common composite fertilizer that is worth, and obviously improve the quality of tomato, V in the tomato
CContent can improve 5%～10%, and the solubility total reducing sugar increases about 7%, and sugar/acid is had improvement significantly.Test on the outdoor vegetable shallot shows, compares between the shallot yield increased increase by 5%～12% V in the shallot with using the common composite fertilizer with value
CContent improves about 8%.Test on apple shows, compares the apple production comparison according to increasing by 10% with using the common composite fertilizer with value, and the solubility total reducing sugar in the apple increases content and adds about 7%.Test on wheat shows, compares the wheat yield comparison according to increasing by 6%～9%, protein increase by 4%～7% with use with the urea that is worth.
Excellent results of the present invention is as follows:
1, the slow release type nitrogen potassium of the present invention production cost that topdresses is low, is easy to realize;
2, the present invention with the slowly-releasing of fertilizer be applied in topdress on, significantly improve fertilizer utilization ratio, effectively prevent and treat environmental pollution;
3, fertilizer of the present invention can significantly improve crop yield, improves quality of agricultural product;
4, fertilizer of the present invention has the effect of significantly improving the soil, and can improve soil sustainable use ability.
