Abstract
The controlled releasing clay mineral fertilizer is produced with composite fertilizer, clay mineral as delayed releasing agent and water and salt as adhesive, and the production process includes material weighing, mixing, crushing, pelletizing, coating fine powder, stoving, cooling, sieving, coating superfine powder and polishing to form primary product, mixing and packing the finished product. The controlled releasing clay mineral fertilizer has simple production process, low cost, no environmental pollution, high utilization, wide application, and other features, and may be produced separately as controlled releasing fertilizer specially for hybrid rice, controlled releasing fertilizer specially for high quality rice, controlled releasing fertilizer specially for tea, controlled releasing fertilizer specially for fruit tree, controlled releasing fertilizer specially for flower, etc.
Description
One, technical field: the present invention relates to capital goods in the agricultural sector and make field, particularly a kind of clay mineral controlled releasing fertilizer and production technique thereof.
Two, background technology: since nineteen twenty-four, urea-formaldehyde fertilizer was obtained patent, slow release fertilizer has rapid progress, in recent years develop into may command again and discharge fertilizer (cou-trolledavailability fertilizers CAFS), and some practical application in agriculture production.Over particularly past 30 years, carried out big quantity research abroad, the release fertilizer of having produced and sold reaches tens of kinds, and its production approach mainly contains following 4 kinds: 1) synthetic delaying is dissolved with machine nitrogenous fertilizer, pitches ten ureas (IBDV) etc. as urea formaldehyde VF, isobutyl; 2) synthetic slow molten inorganic nitrogenous fertilizer is as magnesium ammonium phosphate etc.; 3) coating (wrapping up in) release fertilizer, as sulfur coated urea, coating urea, Nutricote CAFS Luxuriance (happy happiness is executed) etc.; 4) produce the slow release fertilizer that inhibitor is improved, as long-term efficiency bicarbonate ammonium (adding the DCD of improvement), long-acting carbamide (adding HQ) etc.Though the result of use of these release fertilizer is fine, cost of development height, price are expensive, are not suitable for the needs of the various plant husbandry in Chinese vast rural area.At home, research release fertilizer is started late, and mainly concentrates on aspects such as gardening and special fertilizer for lawn, and, mostly be to adopt plastic waste and organic polymer to do coated fertilizer, not only the price height also will bring secondary pollution to the farmland.
Three, summary of the invention: technical problem to be solved by this invention provide a kind ofly have that production technique is simple, cost of development is low, nuisanceless, chemical fertilizer utilization ratio is high, be widely used, cheap controlled release special fertilizer.
The technical solution used in the present invention be with nitrogenous fertilizer or phosphate fertilizer or potash fertilizer or contain the compound of nitrogen, phosphorus, potassium fertile with account for the clay mineral sustained release dosage of weight quota 3～8% and 2～3% water salt binding agent mixing granulation is made following primary products:
A, to make fast release with 1: 1 type layered clay mineral sustained release dosage fertile;
B, make slowly-releasing with 2: 1 type chain clay mineral sustained release dosages and put fertilizer;
C, make slow release with 2: 1 type layered clay minerals or 2: 2 type clay mineral sustained release dosages and put fertilizer;
Get respectively that a certain proportion of fast release is fertile, slowly-releasing is put fertilizer, slow release put fertile mix clay mineral controlled releasing fertilizer.
Discharge soon in primary products that fertilizer, slowly-releasing are put fertilizer, slow release carries out coating with the clay mineral fine powder that accounts for weight quota 3～10% respectively after putting fertile granulation:
A, fast discharge fertile after granulation with 1: 1 type layered clay mineral fine powder coating;
B, slowly-releasing put fertile after granulation with 2: 1 type chain clay mineral fine powder coatings;
C, slow release put fertile after granulation with 2: 1 type layered clay minerals or 2: 2 type clay mineral fine powder coatings.
After primary products discharge fertilizer, slowly-releasing soon and put fertilizer, slow release to put fertile granulation, coating respectively with accounting for the hydrophobic vegetables oil binding agent of weight quota 0.1 5～0.2% and 1～3% clay mineral ultrafine powder is carried out capsule polishing:
A, the fast fertilizer that discharges carry out capsule polishing with 1: 1 type layered clay mineral ultrafine powder;
B, slowly-releasing are put fertilizer and are carried out capsule polishing with 2: 1 type chain clay mineral ultrafine powders;
C, slow release are put fertilizer and are carried out capsule polishing with 2: 1 type layered clay minerals or 2: 2 type clay mineral ultrafine powders.
The technological process of production of clay mineral controlled releasing fertilizer of the present invention is:
Clay mineral controlled releasing fertilizer of the present invention, be to adopt very general clay mineral as sustained release dosage, binding agent also is to adopt common water salt, and its production technique and common production of compound fertilizer technology are approaching substantially, utilize existing compound fertilizer production equipment to improve a little and can produce, thereby, its production technique is simple, and cost of development is low, and is nuisanceless, cheap, the needs of the various plant husbandry in relatively more suitable Chinese vast rural area.Clay mineral controlled releasing fertilizer of the present invention can be made into such as kinds such as super hybridized rice controlled release special fertilizer, extraordinary grain quality rice controlled release special fertilizer, common rice controlled release special fertilizer, tealeaves controlled release special fertilizer, fruit tree controlled release special fertilizer, decorative flower controlled release special fertilizers, use very extensive, according to test: it is special-purpose fertile to use the super hybrid rice slowly-releasing, waits nutrient unit matter rich water rice to increase production 13.1～15.4% than using; The grain protein-n increases by 1.5～1.7%, and utilization rate of nitrogen fertilizer improves 22.7～24.9%, and phosphate fertilizer utilization efficiency improves 3.6～9.0%; General late rice per mu yield can reach about 580kg, and semilate rice reaches more than the 680kg, surveys and produces about homemade multiple fertilizer such as the nutrient of checking and accepting ratio and import composite fertilizer volume increase 10-15%; The non-irrigated grain of field demonstration, vegetables, tealeaves, fruit tree are increased production more than the 15-30%, and crop quality also significantly improves.
