Surface, second is that infiltration in epidermis and stomata, three be in cell.All there is stomata in any vegetables surface layer, leaf vegetables compares fruit vegetables
More, leaf vegetables are easy to absorb pesticide, and also leaf vegetables is thinner than the wax layer of fruit vegetables Cuticle of cell, the pesticide of absorption
It is natural more than fruit vegetables, and pesticide also tends to be to be sprayed on the blade of vegetables, so pollution is most susceptible to, although leaching
It is soaked wash to remove stay in the part on surface, but the remains of pesticide in stomata is not cleaned.The reason is that working as vegetables
After impregnating in water, water absorbs water simultaneously to the stomata permeation cell of vegetable surface, so staying the agriculture in vegetables hole and capillary
Medicine is to be not easy to be flush with water or enter in water, and there is also pesticide and bacterium are miscellaneous simultaneously for the water being inhaled into cleaning process
Matter can also generate vegetables different degrees of secondary pollution, and current existing sterilization method is difficult to realize remove.
The method for removing pesticide residue now is all often that the clear of pesticide residue is carried out when reprocessing after vegetables harvest
It removes, since pesticide residue is formed in field, secondary pollution is often resulted in when harvesting, transporting.
Invention content
It is an object of the invention to provide one kind before vegetables harvest, in the method that pesticide residue is removed in field.
The purpose of the present invention is what is be achieved through the following technical solutions, the method for removal pesticide residue includes before vegetables harvesting
Following steps：
The 6-7 days spraying pesticide residue removal liquid before vegetables harvest, leaf vegetables want complete stool sprays, fruits and vegetables class vegetables uniform
It sprays on fruit, the pesticide residue removes liquid by dietary fiber acidified milk, surfactant, cured matter lytic agent compounding system
At.
The compound proportion of the dietary fiber acidified milk, surfactant and cured matter lytic agent is 10:2:1.
The surfactant be fatty alcohol polyoxyethylene ether, sucrose fatty acid ester mixture；
The cured matter lytic agent is n-hexane；
The preparation method of the dietary fiber acidified milk：
Using fresh milk as raw material, or by whole-fat milk powder by 1:8 ratio is mixed with warm water, and milk powder is made to become uniform milk,
And through 70 DEG C of the pre-heat treatments.Dietary fiber, xylo-oligosaccharide, white granulated sugar are then added successively, are uniformly mixed.It is connect at 40 DEG C~45 DEG C
Kind lactic acid bacteria, inoculum concentration are 2 %, the heat-preservation fermentation 5-6h of milk, then the h of 8h~10 that ferment after 3 DEG C~7 DEG C, are sent out
Kefir milk is spare.
The bean dregs dietary fiber or wheat bran dietary fiber that the dietary fiber is bean dregs, wheat bran extracts.
The lactic acid bacteria is Lactobacillus delbrueckii and streptococcus thermophilus compound bacteria, usage ratio 1: 1.
The xylo-oligosaccharide additive amount 0.6%, white granulated sugar additive amount 3%.
The pesticide residue removes the preparation method of liquid：Surfactant, cured matter lytic agent, warp is added in above-mentioned acidified milk
It crosses and is sufficiently stirred homogeneous.
In use, above-mentioned pesticide residue, which is removed liquid, dilutes 20-30 times, sprayed within 6-7 days on vegetables before vegetables harvest,
The remains of pesticide for being attached to vegetable plant strain surface and being deep into wax layer can preferably be removed.
Dietary fiber acidified milk have the function of it is stronger hold oil, water holding, increase-volume and inducing microbial, can chelating be attached to vegetable
Dish plant remained on surface pesticide molecule, heavy metal ion objectionable impurities；
Surfactant have the effects that emulsification, dispersion, wetting and infiltration, cured matter lytic agent under the cooperation of surfactant,
Wax layer on vegetable plant strain surface is decomposed, to enhance removing of the dietary fiber acidified milk to its remains of pesticide.
The beneficial effects of the invention are as follows：First, when will remove the link of pesticide residue by current fruits and vegetables, advance to
It is completed in field before vegetables harvesting, when preferably resolving vegetables harvesting, transport, since vegetable surface attachment pesticide residue is easily sent out
The problem of raw secondary pollution, pesticide residue is just disposed before so that vegetables is entered processing workshop.Second is that having due to removing liquid
It decomposes, adsorb, the function of chelating, can not only dispose the pesticide molecule being attached on vegetable surface, moreover it is possible to wax layer will be deep into
Interior remains of pesticide is disposed.Third, being inhaled by vegetables since pesticide residue removing liquid contains a large amount of amino acid isoreactivity ingredient
It receives, vegetable leaf good luster.
Field trial data
It selects protecting field greenhouse gardening cucumber as experiment vegetables, is respectively 20 squares by two neighboring area in the cucumber best fruiting period
The green cucumber furrow of rice, as test group and control group, the management level of two groups is consistent, and cucumber growing way is consistent, especially agriculture
Medicine is consistent using type and quantity, and the cucumber growth phase sprays pyraclostrobin and cymoxanil 6 times altogether.Test group is before cucumber harvests
6 days selection fine days spray one time by pesticide residue scavenging agent of the present invention, control group spray clear water, after spraying 6 days, each
Group selects 5 plants of cucumber, every plant of cucumber to pluck two sizes cucumber identical as possible, take laboratory to cucumber pesticide in different points
Residual is detected.
By the cucumber sample homogenization of test group and control group, the cucumber sample of 20g crushing is accurately weighed（It is accurate to 0.01
g）In 100mL centrifuge tubes, 15mL acetonitriles are added, fully vibrates 3min, adds 7g anhydrous magnesium sulfates and 2g sodium chloride, fully shake
