Description

Fog drop evaporation retardant and its preparation and application
Technical field
The present invention relates to agricultural chemicals dispenser field, a kind of fog drop evaporation retardant and its preparation and application are particularly related to.
Background technology
General agricultural chemicals all carries out dispenser after being watered dilution with spraying apparatus.Circulation and rural laborer with soil Transfer, aviation plant protection has been risen now, i.e., carry out dispenser with someone's aircraft or unmanned plane, be characterized in rapidly and efficiently, Not low, a tractor serves several purposes of damage crops, labour intensity etc..
Aviation plant protection has the advantages that strong adaptability, safe and efficient, water saving, but because the flying height of aircraft is generally 2 ~8m, droplet is easily influenceed during whereabouts by temperature, humidity, wind direction, wind speed etc., and droplet is during whereabouts Easy drift, evaporation, because droplet evaporates drift, are just difficult to fall plant surface, and the utilization rate of agricultural chemicals receives certain shadow Ring, have impact on prevention effect.Therefore, in order to reduce the evaporation of droplet, the utilization rate of agricultural chemicals is improved, suppresses the moisture evaporation of droplet Into a major issue for being badly in need of solution.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of fog drop evaporation retardant and its system for reducing droplet evaporation Standby and application method.
In order to solve the above technical problems, present invention offer technical scheme is as follows：
On the one hand, there is provided a kind of fog drop evaporation retardant, it is made up of following weight percent composition：Bio-extract 5% ~50%, polyalcohol 5%~30%, formulation fertilizer containing nitrogen 5%~15%, organosilicon 0.1%~5%, balance of water.
Further, described fog drop evaporation retardant, is made up of following weight percent composition：Bio-extract 20% ~40%, polyalcohol 10%~20%, formulation fertilizer containing nitrogen 5%~10%, organosilicon 3%~5%, balance of water.
Further, the bio-extract be marine algae extract, aloe extract, chitin derivativ in one kind or It is various.Such material contains amino acid, mucopolysaccharide, algae essence polymer etc., with good moisture-keeping function, these bio-extracts Commercially produced product is, can be obtained by commercially available approach.
Further, the polyalcohol is the one kind or many in glycerine, propane diols, butanediol, sorbierite, polyethylene glycol Kind.
In the present invention, described bio-extract and polyalcohol can be by macromolecular compounds and micromolecular compound The hydrophilic radical such as hydroxyl interacted with solvent water molecules, the ability for grabbing water and solid water is played in collaboration.
Further, it is described weightening component be diatomite, kaolin, white carbon, calcium carbonate, formulation fertilizer containing nitrogen in one kind or It is various.
Weightening component is preferably formulation fertilizer containing nitrogen, and the formulation fertilizer containing nitrogen is urea, ammonium chloride, ammonium sulfate, ammonium nitrate, phosphoric acid One or more in ammonium, ammonium hydrogen carbonate, formulation fertilizer containing nitrogen can mainly increase the proportion of droplet, increase the settling property of droplet, Drift is reduced, and formulation fertilizer containing nitrogen is nutrition necessary to crop, is served both functions.
Further, the organosilicon is organosilicon S903, and organosilicon S903 is Beijing Guang Yuan benefit agrochemical in the present invention The organosilicon product of Co., Ltd's production, composition is mainly modified organic silicon polyether.Described organosilicon has been mainly To sealing process, because organosilicon has very low surface tension, can be quickly move to droplet surface, formed in droplet surface Molecular shield, suppresses moisture evaporation.
It should be noted that bio-extract of the present invention and organosilicon product are commercially available prod, ability can also be used Field technique personnel it is conceivable that the various materials for meeting foregoing principle, do not influence the realization of technical solution of the present invention.
On the other hand, the present invention also provides the preparation method of above-mentioned fog drop evaporation retardant, including：
Step 1：In the reactor of 18 DEG C~30 DEG C of temperature, water and organosilicon are added, stirred；
Step 2：To polyalcohol and weightening component in the mixture in step 1, is added, stir；
Step 3：Bio-extract is added in gained mixture in step 2, is stirred, be reduced to room temperature discharging, i.e., Obtain fog drop evaporation retardant.
Another further aspect, present invention also offers the application method of above-mentioned fog drop evaporation retardant, before pesticide spray dispenser Directly it is used in mixed way with pesticidal preparations in bucket or tank.
Further, ratio of the fog drop evaporation retardant in pesticidal preparations is 0.5%-3%.
The invention has the advantages that：
(1) inhibitor for reducing droplet evaporation of the invention, due to adding bio-extract, not only environmental protection, and And containing various natural macromolecule moisturizing ingredients, can be good at being interacted with hydrone, water conservation solid water effect is good；
(2) inhibitor for reducing droplet evaporation of the invention, adds the polyalcohol of small molecule, with natural biological extract In the presence of synergy, the holding performance to water is increased；
(3) inhibitor for reducing droplet evaporation of the invention, is also added into organosilicon, can not only reduce the surface of system Tension force, and organosilicon has certain inhibitory action in droplet surface aggregation to hydrone evaporation.
