Abstract
The invention relates to a preparation method of a pesticide residue toxinicide for agricultural products, which comprises the following steps: (1) mixing 0.6-2.1% of nano zinc oxide, 40-50% of percarbonate, 0.4-1.6% of potassium selenite and right amounts of pure water, and continuously stirring until all the components are completely dissolved; and (2) continuing adding pure water to the total weight percentage of 100%, and stirring uniformly. The toxinicide prepared by the method provided by the invention can effectively reduce the pesticide residue by more than 70%, and can degrade the pesticide residue on the agricultural product and lower the pesticide residue in the agricultural product.
Description
Technical field
The present invention relates to the preparation method of Practice for Pesticide Residue in Agricultural Products antipoison.
Background technology
Residue of pesticide refer to because pesticides application remains in the agricultural chemicals parent in organism, agricultural product and environment and has the general name of impurity, metabolite and the reaction of toxicology meaning.China is world pesticide production and uses big country.A large amount of residue of pesticide can cause acute toxicity.Remains of pesticide also can be accumulated in human body, can cause some diseases over after a certain amount of, as angiocardiopathy, diabetes, hepatopathy, cancer etc.; Agricultural chemicals accumulating also in human body can be passed to the next generation by pregnant and lactation, brings disaster to descendants's health.Bread is the staff of life, and food is with An Weixian.When food industry had developed into the large industry of the first in the world, food security also was subject to extensive concern.Therefore, the residue of pesticide of reduction agricultural product are trends of the times.Product in the market belongs to types of detergents mostly, real degrading pesticide, and can cause secondary pollution to water quality.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of Practice for Pesticide Residue in Agricultural Products antipoison makes both can the degrade residue of pesticide on crops surfaces of antipoison and can also reduce the agricultural chemicals that infiltrates through crops inside, drops into low and effect is remarkable.
Residue of pesticide antipoison of the present invention is comprised of the component of following percentage by weight:
Nano zine oxide 0.6-2.1%
Percarbonate 40-50%
Potassium selenite 0.4-1.6%
Surplus is pure water.
Wherein nano zine oxide has good photocatalysis performance, and it can absorb luminous energy, produces the material with strong oxidizing property and comes chemical bond in degrading pesticide.Percarbonate can be SODIUM PERCARBONATE, potassium percarbonate, is the strong oxidizing property material.Selenium in potassium selenite can enter rapidly plant cell in photosynthesis, add the foreign substance removing function of cell, accelerates simultaneously the aging of pesticide molecule chain and fracture, greatly reduces the residue of pesticide in crops.
The preparation method of above-mentioned antipoison comprises the following steps:
(1) 0.6-2.1% nano zine oxide, 40-50% percarbonate, 0.4-1.6% potassium selenite and appropriate pure water are mixed, constantly stir until all components dissolves fully;
(2) continuing to add pure water to make total weight percent is 100%, stirs.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail.But the invention is not restricted to given example.
Embodiment 1

Nano zine oxide 0.6%
SODIUM PERCARBONATE 40%
Potassium selenite 0.4%
Surplus is pure water.
The preparation method of the residue of pesticide antipoison of the present embodiment comprises the following steps:
(1) 0.6 nano zine oxide, 40% SODIUM PERCARBONATE, 0.4% potassium selenite and appropriate pure water are mixed, constantly stir until all components dissolves fully;
(2) continuing to add pure water to make total weight percent is 100%, stirs.
Embodiment 2
The component of the following percentage by weight of residue of pesticide antipoison of the present embodiment forms:
Nano zine oxide 1.0%
Potassium percarbonate 45%
Potassium selenite 1.0%
Surplus is pure water.
The preparation method of the residue of pesticide antipoison of the present embodiment comprises the following steps:
(1) 1.0 nano zine oxides, 45% potassium percarbonate, 1.0% potassium selenite and appropriate pure water are mixed, constantly stir until all components dissolves fully;
(2) continuing to add pure water to make total weight percent is 100%, stirs.
Embodiment 3
The component of the following percentage by weight of residue of pesticide antipoison of the present embodiment forms:
Nano zine oxide 2.1%
Potassium percarbonate 50%
Potassium selenite 1.6%
Surplus is pure water.
The preparation method of the residue of pesticide antipoison of the present embodiment comprises the following steps:
(1) 2.1% nano zine oxide, 50% potassium percarbonate, 1.6% potassium selenite and appropriate pure water are mixed, constantly stir until all components dissolves fully;
(2) continuing to add pure water to make total weight percent is 100%, stirs.
The method that adopts the various embodiments described above residue of pesticide antipoison to process crops comprises the following steps:
(1) with 20 times of above-described embodiment residue of pesticide antipoison dilutions;
(2) reach 24 hours after pesticide spraying, before the 1-2 before crops are gathered days, the antipoison that dilutes is sprayed at crop surface;
(3) expose at least 10 hours under sunlight or artificial light source.
Processing crops with above-described embodiment residue of pesticide antipoison can effectively reduce residue of pesticide more than 70%, and the residue of pesticide of the surface of agricultural products of can degrading, and can reduce again the persticide residue of agricultural product inside.
Claims (1)
1. the preparation method of a residue of pesticide antipoison, is characterized in that, comprises the following steps:
(1) 0.6-2.1% nano zine oxide, 40-50% percarbonate, 0.4-1.6% potassium selenite and appropriate pure water are mixed, constantly stir until all components dissolves fully;
(2) continuing to add pure water to make total weight percent is 100%, stirs.
