Abstract
A granular compound fertilizer comprises the following components in percentages by weight: 33-42% of urea, 26-35% of calcium triple superphosphate, 16-25% of potassium chlorate, 0.4-0.8% of boric acid, 0.8-1.2% of magnesium sulfate, 0.2-0.6% of zinc sulfate, 0.08-0.14% of copper sulfate, 6-12% of medicinal residue, 7-16% of bone powder, and 1.5-8% of fly ash. The granular compound fertilizer and the production method in the invention have the advantages of containing 18 kinds of elements, thereby improving the comprehensive fertilizer effects, and low production cost.
Description
Technical field:
The present invention relates to a kind of granular compound fertilizer and working method thereof.
Technical background:
Composite fertilizer is the general name that contains the fertilizer of two or more element in nitrogen, phosphorus, three kinds of nutritive elements of potassium.Advantages such as composite fertilizer has the nutrient content height, minor component is few and physical behavior is good for balance fertilizing, improve utilization rate of fertilizer, promote the stable high yield of crop that crucial effect is arranged.Along with the raising of grain yield, the phenomenon of soil nutritional deficiency shows, and the peasant begins to select for use more multi-component composite fertilizer now.
Composite fertilizer's customizations is a megatrend of composite fertilizer development: because crop is in different vegetative period, main organ of growing is different, such as at germination period; Mainly be the growth of rhizome, and mainly be the growth of cauline leaf vegetative period, the ripening stage then mainly is the growth of flowers and fruits seed; Different plant organs; Required main fertilizer also is different in growth course, and the peasant will select corresponding special-purpose fertile according to the different growing stages of crop when selecting composite fertilizer for use.Just run counter to crop if not special use and inhaled fertile rule, made the yield potential of crop can not get performance, caused some nutritive element waste simultaneously.Along with the development of agriculture prodn, the composite fertilizer of high-concentration long-actingization more and more receives peasant's welcome, and the application of this type fertilizer has reduced the fertilising consumption; Make things convenient for farming, remove the link of topdressing from, alleviated labor capacity; Improved utilization rate of fertilizer, the saving of labor, laborsaving, save time upgrading synergy.
Composite fertilizer's fertilizer efficiency is long, is fit to do base manure.A large amount of tests show, no matter be that binary should ternary is compound be all executed with base.This is because contain multiple nutrients such as nitrogen, phosphorus, potassium in the composite fertilizer, and crop is especially very responsive to phosphorus, potassium early stage, requires phosphorus, potash fertilizer will make base manure and early executes.Controlled-release compound fertilizer has adopted technologies such as dressing, granulation in process of production, and fertilizer efficiency is slowly steady, decomposes slowly than chemical fertilizer of simple substance, and leaching loss of nutrient is few, and utilization ratio is high, is suitable for doing base manure.But the element that plant needs is not a nitrogen, phosphorus, and potassium also needs elements such as calcium, magnesium.Composite fertilizer in the market just comprises large elements such as the required N of crop, P, K, and crop vegetative period necessary trace element be left in the basket for a long time, and the effect of trace element in the growth and development process of crop is absolutely necessary.
At present there are several kinds as the quick-acting and long-acting compound manure that combines; Press compounded granular fertilizer like U.S. home-made di(2-ethylhexyl)phosphate; It mainly contains 18% nitrogen, 46% phosphorus, and its weak point is that this inorganic fertilizer is prone to harden soil, still deficiency and price are higher for the element kind that is made for thing growth usefulness.
Summary of the invention
The object of the present invention is to provide a kind of cheap compounded granular fertilizer and working method that contains multiple element and can improve the soil.
The object of the invention can be realized through following measure: a kind of multi-element particle fertilizer, it includes urea, double superhosphate, Potcrate, boric acid, sal epsom, zinc sulfate, copper sulfate, the dregs of a decoction, bone meal and flyash.
Weight percent of the present invention consists of:
Urea 33-42%, double superhosphate 26-35%, Potcrate 16-25%, boric acid 0.4-0.8%, sal epsom 0.8-1.2%, zinc sulfate 0.2-0.6%, copper sulfate 0.08-0.14%, dregs of a decoction 6-12%, bone meal 7-16%, flyash 1.5-8%.
Preparing method of the present invention is following:
(1) will make it to become 100-200 purpose fine powder except that the raw material pulverizing the dregs of a decoction and the copper sulfate, grinding;
(2) dregs of a decoction and copper sulfate are paste through levigate, mixing;
(3) above-mentioned fine powder and paste are mixed back granulation, drying.
As stated, the raw material that granulated fertilizer of the present invention adopted comprises two portions, and a part is conventional inorganic fertilizer such as urea, double superhosphate, Potcrate, boric acid, sal epsom, zinc sulfate, copper sulfate; Another part then is a waste material, like the dregs of a decoction, bone meal and flyash.
As stated, the dregs of a decoction are to be the waste residue of the various medicaments processed of raw material with grain.Bone meal is that the discarded bone with animal such as ox, horse, sheep, pig makes through processing.
Compared with techniques prior art of the present invention has following advantage:
(1) quality standard that not only reaches existing U.S. di(2-ethylhexyl)phosphate money granulated fertilizer is nitrogenous 20%, phosphorus 48%, but also contain 18 kinds of elements, comprehensive fertilizer efficiency is improved.
(2) a raw material part of the present invention adopts waste to make the three wastes be able to comprehensive utilization, both has been of value to environment protection, also reduces production costs significantly.
(3) except that containing mineral manure, also contain many organism in the fertilizer of the present invention, they are not merely crop provides growth needed nutriment, and remaining can not can also being improved the soil by the material that crop absorbs make soil property loose, remedies many deficiencies of chemical fertilizer.
(4) not only contain quick-acting components in the fertilizer of the present invention, and contain long-acting component again, strong to crop different growing stages flexibility.
