Description
Technical field
The present invention relates to a kind of compound fertilizer and production method thereof, particularly a kind of drought-resisting water-maintaining multifunctional compoiste fertilizer and preparation method.
Background technology
Compound fertilizer refers to containing two or three main plant nutrient nitrogen, phosphorus or nitrogen, phosphorus, the general name of fertilizer of potassium; it produces and the purpose of use is to meet agricultural sciences fertilising and the requirement of economic fertilization; improve fertilization effect, development high performance and fine agriculture and preserve the ecological environment, one of its development degree measurement index becoming agricultural modernization.From the developing direction of fertilizer the most in the world, the research of fertilizer is primarily intended to Ecological harmony fertilizer, is i.e. conducive to efficiently volume increase, the improvement of beneficially environmental conservation, beneficially soil.China is large agricultural country, and very big to the annual requirement of compound fertilizer, current composite heat transfer is still based on traditional N-P-K NPK.Practice have shown that, this traditional compound fertilizer is producing and there is also weak point in actual application: (1) lacks trace element such as magnesium, boron, ferrum, zinc, cobalt, copper, manganese, molybdenum etc. necessary to crop growth, easily causes the unbalanced problem of crops nutrient.(2) in drought and water-scarce area, hills, mountain region and highlands, it is difficult to play high fertilizer efficiency.(3) lacking organic principle, chronic administration makes soil aggregate be destroyed, and is easily caused soil compaction, is unfavorable for plant growing.Therefore, it is necessary to composition and production technology thereof to conventional composite fertilizer carry out Improvement so that it is function diversification, production technology is efficient, to promote China's agricultural modernization, the demand of satisfied development "three highs" agriculture.
Summary of the invention
It is an object of the invention to provide a kind of nutritive element balance, containing trace element necessary to plant growing and Organic substance, and there is drought-resistant water-preserving function and the drought-resisting water-maintaining multifunctional compoiste fertilizer of soil improvement function.
Another object of the present invention is to provide a kind of granulation efficiency high, prepare the preparation method of the good above-mentioned drought-resisting water-maintaining multifunctional compoiste fertilizer of product particle intensity.
The drought-resisting water-maintaining multifunctional compoiste fertilizer of the present invention is 5 by percentage by weight～one or several in magnesium and trace element of 13% nitrogen, 5～11% phosphorus, 5～10% potassium, 1～15% anti-drought water-retaining agent, 10～30% Organic substance, 0.001～0.1% adhesive, 0.3～3% form.Wherein trace element is zinc, ferrum, manganese, copper, cobalt, molybdenum, boron, Organic substance is fowl and animal excrement, humic acids, peat soil or filter mud of sugar refinery, anti-drought water-retaining agent is super absorbent resin, can be that starch acrylonitrile graft is polymerized hydrolysate, starch acrylic acid graft copolymer, starch styrene sulfonic acid graft copolymer, starch vinyl sulfonic acid graft polymers, potato starch acrylamnide graft polymers, polyacrylic acid (salt) class cross-linking agent, acrylic acid (salt) acrylamide copolymer, polyacrylamide, polyvinyl alcohol anhydride cross linked polymer, polyvinyl alcohol acrylic acid graft copolymer, vinyl acetate acrylic acid branch copolymerization hydrolysis or polyvinyl alcohol crosslinked polymer.And adhesive is polyacrylate solution, being especially concentration 0.05～the sodium polyacrylate of 0.5% molecular weight 1,000,000～30,000,000 or polyacrylic acid potassium solution, multiple powder is Kaolin, clay, Gypsum Fibrosum powder, Pulvis Talci or agstone.
The preparation method of drought-resisting water-maintaining multifunctional compoiste fertilizer of the present invention, comprises the steps of: (1) is 5 by percentage by weight～13% nitrogen, 5～11% phosphorus, 5～10% potassium, 1～15% anti-drought water-retaining agent, 10～30% Organic substance, 0.001～0.1% adhesive, 1～35% multiple powder, 0.3～3% one or several mix homogeneously in magnesium and trace element；(2) pelletize；(3) it is dried, packs after screening.
First crushing material before mixing, then adds in granulating disc by half material, sprays adhesive under rotary state, stops adding adhesive after material forms little granule, is added by remaining half material and continues pelletize.After pelletize completes, use far-infrared technique to carry out being dried of product, pack after finally sieving by vibrosieve.
nullThe drought-resisting water-maintaining multifunctional compoiste fertilizer of the present invention，Magnesium is added on the basis of tradition N-P-K tri compound fertilizer formula、Copper、Ferrum、Zinc、Boron、Manganese、Cobalt、Trace element and Organic substance necessary to the crops such as molybdenum and plant growing，Add a certain amount of anti-drought water-retaining agent and Organic substance simultaneously，Make it have drought-resistant water-preserving function and certain soil improvement function，And utilize adhesive and use batch charging pelletize、Far-infrared drying technology is produced a kind of nutritive element balance and has drought-resistant water-preserving、The Multifunction compoiste fertilizer of soil improvement action，This fertilizer can not only play efficiently effect in the few water area of arid，And different types of crops and plant can be applicable to，It is particularly suited for coastal arid tract、The crops such as hills and mountain forest area and plant and city trees and shrubs、Flowers、The plantation on lawn etc. is used.
Below example contributes to the those of ordinary skill in field of the present invention and is further appreciated by the present invention, but limits the present invention never in any form.
