Essential oil is in the flower from plant, leaf, stem, root or fruit, passes through steam distillation, extrusion, cold-maceration or molten
Agent extraction method refines the volatile flavor of extraction.Not all plant can output essential oil, only containFace creamGland
Plant be likely to output essential oil.Thus seem more not precious, ton price is in tens of thousands of or even hundreds of thousands of, expensive, dosage
Big then higher cost, relative to the agricultural of low yield value, peasant can not receive, and dosage does not work then less, it is difficult to push away in market
Extensively.
Essential oil after mostly using dilution at present, essential oil is due to immiscible with water, therefore, it is impossible to simply be diluted with water, usually
It is diluted using alcohol, and alcohol price is much higher than water, and essential oil itself is volatile materials, alcohol is also volatile matter
Matter will be applied to agricultural with the diluted essential oil of alcohol, deposit a large amount of volatilizations after use, essential oil utilization rate is low, can not play completely
The problem of essential oil effect.
Essential oil and water through ultrasound, shearing or it is homogeneous be allowed to be dispersed in water, essential oil is present in water in the form of droplet,
It due to the presence of essential oil droplet after application, can not be sprawled rapidly on plant leaf blade, and it is excessive and unfavorable to sprawl rear contact angle
In plant absorption.
Essential oil is poor there are at high cost, compatibility applied to agricultural at present and effect is not significant.
China's utilization rate of fertilizer is low at present, and wherein utilization rate of nitrogen fertilizer is 30% or so, and phosphate fertilizer utilization efficiency is 20% or so, potash fertilizer
Utilization rate be 40% or so, member of Chinese Academy of Engineering, Beijing Forestry University professor Lin Weilun once counted China grain yield and
Rate of fertilizer, China's grain yield account for the 16% of the world, and fertilizer amount accounts for 31%, and per hectare dosage is the 4 of world's average dose
Times, excessive chemical fertilizer is flushed to underground by water quickly, influences the nutrient balance of soil.
Utilization rate of fertilizer is improved, the usage amount for reducing fertilizer becomes the matter of utmost importance of agricultural at present.

1. the application makes liquid in solid material table by adjusting the mass ratio of alcohol and essential oil by controlling the range of HLB value
Contact angle on face is less than 90 DEG C, and to improve the spreadability of essential oil, to improve the utilization rate of nutriment, HLB value is small to be unfavorable for
Wetting, HLB value is big, i.e., surfactant is excessively hydrophilic, and the cuticula of blade surface is hydrophobic layer, and the two compatibility differs very
Greatly, it is unfavorable for nutriment infiltration in blade.
2. the application limit glycerol content, to prevent glycerol content excessive, using time slice cause plant cell be dehydrated and
It is dead.
3. the application select nonionic surfactant, make it possible to alcohol compatibility, further increase drug effect, such as select
Anionic surfactant, then polarity precipitating easily occurs with the anion in anionic surfactant for alcohol, and raising is not achieved
Cationic surfactant is selected in the effect of fertilizer efficiency, is since cuticula and the soil institute on plant leaf blade surface are electrically charged
The effect for improving fertilizer efficiency is also not achieved using cationic surfactant easily by plant leaf blade and soil fixing in negative electrical charge.
4. the application also notes that water and anionic surfactant coexist, it is desirable that water and anionic surfactant are total
It is molten, such as not molten layering altogether, then the effect of the application increased operation rate is not achieved.
5. water is added in the application, glycerol and nonionic surfactant can slow down the volatilization of alcohol and essential oil, it is non-from
Sub- surfactant is to reduce the contact area of air and liquid level, to achieve the purpose that reduce volatilization, glycerol is to improve mixing
The boiling point of liquid, to achieve the purpose that reduce essential oil volatilization, to improve the utilization rate of essential oil.
6. the application first uses ethyl alcohol to dissolve each other with essential oil, other solvents are then added, effect is to prevent water from making to essential oil
At demulsification, and then influence the effect of product.
7. utilization rate of fertilizer can be improved in the application, the usage amount of fertilizer is reduced.
