Description
Technical field
The present invention relates to a kind of preparation method of multiple elements design chelating iron fertilizer.
Background technology
Iron is the required nutritive element of plant, in plant materials, participate in multiple physiological action such as Chlorophyll synthesis, redox reaction and electron transmission and respiration etc., impact comprises many physiological processs such as nitrogen metabolism, metabolism of organic acids, carbohydrate metabolism and protoplasma proterties.
By the impact of antagonistic action between soil pH, organic matter, redox potential and nutrient in agriculture production, crop iron deficiency, makes crop leaf chlorosis, occurs that the phenomenon of yellowtop is more and more general.Iron deficiency, affect plant photosynthetic, breathe and metabolism, too little iron can cause plant dead, the iron sensitive crops such as the garden crop of the representative that is especially the leguminous crop of representative with peanut, take wild cabbage as the vegetables of representative, with flower of Capa Jasmine is and tangerine fruit trees.
Iron fertilizer mainly contains inorganic iron fertilizer, chelating iron fertilizer and organic iron fertilizer three kinds on the market.Organic chelated trace fertilizer NaFeEDTA (the EDTA-FeNa3H that DojindoLaboratories company of Japan produces
2o), the Be very effective such as NaFeEDTA ammonium, PDTA iron ammonium of Argentinian QuimicosEssiodS.A. company production; The iron fertilizer that domestic market is sold still based on cheap inorganic iron fertilizer, but causes end-use performance low due to the instability of its character.
It is poor that inorganic iron fertilizer uses solubility effect on the calcareous soil that pH value is higher, because the iron in these iron fertilizers can precipitate rapidly and change into the iron cpd of indissoluble, even increase the amount of application of iron fertilizer, its effect is not still very desirable.Must control below 2 pH value of solution requirement when spraying inorganic iron fertilizer, but this probably causes very large injury to crop leaf, ferrous ion exposes oxidized very soon in atmosphere, forms precipitation, loses the nutrient availability of iron.
Chelating iron fertilizer is generally by iron being had to Fe in the organic acid of high affinity and inorganic molysite
3+chelating forms, and common sequestrant is as ethylenediamine tetraacetic acid (EDTA) (EDTA), diethylenetriamine pentaacetic acid (DTPA), hydroxyethylethylene diamine tri-acetic acid (HEDTA), quadrol two ortho-hydroxyphenyl acetic acid (EDDHA), quadrol two (2-hydroxyl-4-formyl-phenyl) acetic acid (EDDHMA), quadrol two (2-hydroxyl-4-sulfo group-phenyl) acetic acid (EDDHSA) etc.The applicable different pH soil types of chelating iron fertilizer, fertilizer efficiency is higher, and miscibility is strong, but price is more expensive, and the crop that economic worth of being everlasting is higher is used.Chelating iron fertilizer is as EDDHA, HEDTA, EDDHMA class chelated iron, and mainly make containing iron preparation in sale, seldom have the pure chelated iron extensive use of chemical fertilizer compound indicating composition to sell, though effect is good, mostly rely on import, price is high.
Organic composite iron fertilizer refers to the iron fertilizer that the natural organic matter (lignosulfonic acid, humic acid, amino acids, glycitols, marine alga liquid) utilizing some to extract from plant is compounded to form with iron, as ironic citrate, ferrous gluconate.Though compoiste fertilizer cost is low, huge legendary turtle closes ability, and the chelate iron character of formation is also unstable, is difficult to reach required fertilizer efficiency.
China produces chelating iron fertilizer and organic iron fertilizer and application is scarcely out of swaddling-clothes, production technology and the product used of industrialization depend on import mostly, the organic iron fertilizer produced is based on NaFeEDTA ammonium and PDTA iron, and manufacturer is few, and throughput is generally 500-2000t/a.
Iron fertilizer kind on market is more, quality is very different, with low content of technology, result of use is poor, expensive etc., which kind of fertilizer peasant does not know to buy, and one occurs iron deficiency phenomenon, blindly fertilising, effect is had a greatly reduced quality, even if there is high-quality iron fertilizer, or rests on experimental stage, expensive, or can volume production little.The present invention disclosed in CN1103393 is a kind of manufacture method of chelate multicomponent mixed microfertilizer.Based on the multielement micro-fertilizer containing elements such as nitrogen, phosphorus, potassium, boron, manganese, zinc, copper, iron, molybdenums, add sequestrant exactly, utilize sequestrant and multielement micro-fertilizer to carry out sequestering action.
Most current chelating iron fertilizer, based on foliage-spray, mainly because easily solidify at Iron in Soil and run off, is not easily absorbed by plants.Chelated iron has been selected in some areas, but the price of chelated iron is very high at present, is used for the cash crop foliage-sprays such as fruit tree, so seldom see the use of chelated iron on pulse family, vegetables.
Summary of the invention
The object of the invention is for above-mentioned present situation, aim to provide that a kind of stable performance, comprehensive nutrition, use are simple, with low cost, safety and environmental protection, iron deficiency yellowtop can be solved, can crop quality be improved again, improve the preparation method of the multiple elements design chelating iron fertilizer of output.
The implementation of the object of the invention is, a kind of preparation method of multiple elements design chelating iron fertilizer, it is by the raw material of following weight part: EDETATE SODIUM 10-30 part, iron vitriol 10-25 part, amino acid/11 00-400 part, boric acid 20-60 part, Zinc Sulphate Monohydrate 30-70 part, urea 100-500 part, potassium primary phosphate 30-100 part, sorbyl alcohol 10-30 part, polysorbas20 20-60 part, add water fully mixing, be made into the solution of 1000 weight parts, obtain multiple elements design chelating iron fertilizer.
Adopt the using method of multiple elements design chelating iron fertilizer prepared by the present invention: seedling stage sprays to initial bloom stage according to 500-1000 times of liquid on the leguminous crops such as peanut, on the fruit trees such as navel orange the spring slightly to the phase of bearing fruit according to 3-5L/667m
2carry out punching to execute, can effectively prevent and treat and correct iron deficiency yellowtop, simultaneously oil recovery enhancement, improve output.
The present invention has the following advantages:
1, raw material have employed EDETATE SODIUM, amino acid and sorbyl alcohol and carries out chelating to iron vitriol, improves stability and the validity of Crop iron, uses more merely the stability of EDETATE SODIUM to strengthen;
2, the biological effectiveness of prepared using amino acid and sorbyl alcohol, not only provides abundant nutrition to crop, also promotes the growth of crop simultaneously;
3, raw material have employed polysorbas20 as tensio-active agent, effectively can stablize chelated iron, reduces ferrous solution surface tension, increases the maximum liquid holdup of crop leaf;
4, the multiple elements design chelating iron fertilizer of preparation is rich in nitrogen, phosphorus, potassium, zinc, boron, iron and various bioactivators, comprehensive nutrition, effectively can improve crop quality, improves crop yield.
The multiple elements design chelating iron fertilizer adopting the present invention to prepare is used at the fruit tree crop such as leguminous crop, the navel orange foliage-sprays such as peanut or punching and blade can be made multiple green, improves photosynthetic pigments concentration and photochemistry speed, increases iron level, oil recovery enhancement, increase yield.Peanut uses and can increase the distribution of peanut nodule, quantity and size, promote result, amount of increase in production is more than 10%.
The multiple elements design chelating iron fertilizer adopting the present invention to prepare is applicable to control and the rectification of south and north crop iron deficiency, and use simple, efficient, cheap, safety non-pollution can effectively solve iron deficiency yellowtop.
