Technical field
The present invention relates to a kind of compound manure and preparation method thereof, relate in particular to the compound manure that contains yellow phosphorus furnace slag.
Background technology
The solid waste of output when yellow phosphorus furnace slag is producing yellow Phosphorus by electric oven, 8 to 10 tons of yellow phosphorus furnace slags of the about output of 1 ton of yellow phosphorus of industrial every production, its main component is Calucium Silicate powder (SiO
2And CaO).The actual annual output yellow phosphorus furnace slag of China is about 6,000,000 to 7,500,000 tons at present, and wherein small part is used to make cement, brickmaking etc., and is most of discarded.
Compound manure is the fertilizer a kind of commonly used during modern agriculture is produced, and wherein contains in nitrogenous fertilizer, phosphate fertilizer, the potash fertilizer at least two kinds (generally, if with N, P
2O
5, K
2N, P, the K content of O meter are no less than 4% of compound manure total mass, promptly think to contain this kind fertilizer in the compound manure).Along with the raising of farm output, the phenomenon of soil nutritional deficiency is more and more obvious, and the usage quantity of compound manure is also increasing gradually.
The contriver finds that the effect of increasing production of existing compound manure is bad.
Summary of the invention
The invention provides a kind of compound manure, it has good effect of increasing production.
For reaching described purpose, the present invention adopts following technical scheme:
A kind of compound manure that is grouped into by following one-tenth:
Yellow phosphorus furnace slag: massfraction is more than or equal to 5% and smaller or equal to 40%;
In nitrogenous fertilizer, phosphate fertilizer, the potash fertilizer at least two kinds: massfraction is more than or equal to 60% and smaller or equal to 90%;
Additive: surplus.
The present invention also provides preparation to have the method for the compound manure of good effect of increasing production.
A kind of method for preparing compound manure comprises:
The yellow phosphorus furnace slag dehydration is dried;
Yellow phosphorus furnace slag after drying is ground;
With at least two kinds in nitrogenous fertilizer, phosphate fertilizer, the potash fertilizer, additive, and the yellow phosphorus furnace slag after grinding mixes evenly, wherein the massfraction of yellow phosphorus furnace slag is more than or equal to 5% and smaller or equal to 40%, at least two kinds massfraction in nitrogenous fertilizer, phosphate fertilizer, the potash fertilizer is more than or equal to 60% and smaller or equal to 90%, and additive is a surplus;
With the mixture pelleting after mixing;
The gained particle is cooled off.
