Description
Technical field
The present invention relates to a kind of plant fertilizer, particularly a kind of composite iron fertilizer of foliage applying.
Background technology:
Iron deficiency chlorosis symptom often appears in the plant in neutrality or alkaline soil.Its phenomenon be the mesophyll light green to yellow-white, vein still is green.The lighter shows as chlorosis yellow between vein, significant green netted line occurs.The full leaf albefaction of weight person, plant strain growth is weak, and crop yield is reduced, and quality descends.
Plant has the advantage of speed height, instant effect by the most of nutritive substances of Foliage Absorption.Yet because the mechanism of plant leaf Foliage Absorption iron, academia is unclear so far, the also non-constant of ferro element movability in plant materials in addition, spray iron preparation with ordinary method, the multiple green symptom of point-like appears in iron deficiency plant regular meeting, can not reach multiple fully green effect; And adopting the iron administration preparations such as a bottle method, trunk strong injection method that bury commonly used, complicated operation easily produces poisoning.Though the chelated iron (as EDDHA iron) that soil is executed good stability can obtain the multiple green effect of ideal, can only keep that plant is multiple green then, and EDDHA iron production cost height, use complexity, can not extensively apply to agriculture production.Iron fertilizer that need be cheap, easy to use in the production.
Summary of the invention
The invention provides a kind of blade face composite iron fertilizer, its compound method is simple, uses conveniently, and also has advantages such as price is low, foliage-spray is effective.
Technical scheme of the present invention is:
The blade face composite iron fertilizer is that the pH value is 6.0～7.0 the aqueous solution, its main ingredient is included in its ferro element under the vegetable cell environment and is difficult for the chelated iron that cemented out by calcium ion etc., have the auxiliary agent of moisture-absorption water-retention, stabilizing solution potential of hydrogen and inhibition calcium ion concn, promote soup evenly attached to the tensio-active agent on the blade face.The weight part of its each main ingredient is
1 part of chelated iron;
0.25～0.75 part of auxiliary agent;
0.05～0.1 part in tensio-active agent.
Described chelated iron is a diethylenetriamine pentaacetic acid iron ammonium.
Described auxiliary agent is the mixture of any one or two kinds in ammonium citrate, the Tripotassium Citrate.
Described tensio-active agent is an oxyethyl group modification trisiloxanes.
The present invention selects for use suitable chelated iron [as DTPAFe (NH
4)
2], its iron ion in vegetable cell is not dissociated out too quickly [otherwise may produce serious poisoning (as EDTAFe NH
4)].Blade face of the present invention composite iron fertilizer can be avoided iron ion to dissociate out from sequestrant in the process of spraying and generate Fe (OH)
3Colloid and cause the iron fertilizer failure phenomenon.
The present invention selects proper auxiliary agent (as the mixture of any one or two kinds in ammonium citrate, the Tripotassium Citrate) for use, makes it have moisture-absorption water-retention, and the stabilizing solution potential of hydrogen is not decomposed thereby suppress calcium ion concn protection chelated iron.If when atmospheric moisture is excessive, should suitably reduce the ammonium citrate consumption, add Tripotassium Citrate even with the Tripotassium Citrate replacement, in order to avoid airborne moisture of the excessive absorption of soup etc. and form excessive drop and run off from the blade face.Blade face of the present invention composite iron fertilizer has good moisture-absorption water-retention, can guarantee that solution is constantly absorbed by blade.Soup pH value can guarantee that at 6.0～7.0 o'clock oxyethyl group modification trisiloxanes is not hydrolyzed inefficacy; Under this potential of hydrogen, calcium mineral matter of being adsorbed by the blade face etc. also is difficult for dissolvedly, is easy to other mixed pesticides.Citrate ion can be preferentially and the calcium ion complexing, thereby the protection iron ion is not cemented out by calcium ion under higher pH state of value and lost efficacy.
Positively charged ion: preferably select to promote ferruginous negatively charged ion to absorb easily by the ammonium ion of plant absorbing, potassium ion etc.
Tensio-active agent: promote solution evenly attached on the blade face, can select oxyethyl group modification trisiloxane surfactant for use.
Because different leaf table proterties and different to the iron demand, the iron-holder of soup can be different during final spray cloth:, blade face cutin bed thickness serious for iron deficiency, fully-developed plant, (iron content 250～350mg/L) or increase spray number of times can to use higher concentration, on the contrary, can reduce concentration (iron content 150～200mg/L).And the content of ammonium citrate, should be according to the increase and decrease of weather, environmental aspect: dust be adhered to few the time in wet weather, blade face, can reduce the ammonium citrate consumption, on the contrary, increases the ammonium citrate consumption; Under extreme wet weather state, also can be with replacement part ammonium ions such as potassium ions, in order to avoid fluid loss.Oxyethyl group modification trisiloxanes makes soup have good wetting effect as tensio-active agent, and soup more can be evenly distributed in the blade face.During use, its content reaches just enough, the too high concentration of 150～200mg/L, can cause serious poisoning, as cause that blade is burnt, fallen leaves etc.
The present invention adopts the existing reagent in market, is mixed with the blade face composite iron fertilizer under the specific acidity condition, and is therefore cheap, be in the existing market EDDHA iron fertilizer price 1/3, and have and advantage such as use conveniently, foliage-spray is effective.
Weight part of the present invention is gram, kilogram etc.
Diethylenetriamine pentaacetic acid iron ammonium employing iron-holder of the present invention is 6% commercially available DTPA iron ammonium, and ammonium citrate, Tripotassium Citrate, ammoniacal liquor adopt commercially available analytical pure, and oxyethyl group modification trisiloxanes adopts commercially available agricultural organic silicon surfactant.
