basic principle of the present invention
The method is to be exclusively used in the crop growth multifunctional ecological resist technology system in period.
Basic principle containing selenium natural herb pesticide residue scavenging agent (scavenger) is: " the residual remover of agriculture " liquid formulation evenly sprays on plant leaf surface, the special light electrical property stimulating plant cellular enzymes of the contained selenium element of preparation, make cell activation go out a kind of special physiologically active, thereby make plant cell show three large special functions:
1, first show that the opening width that impels plant leaf surface pore increases (on normal opening width basis, increasing by 10%), strengthened the light energy that enters plant cell, increased the absorption of plant leaf surface to CO2, strengthened the photosynthesis of plant.
Photosynthetic increase, improves the ability of the synthetic nutriment of plant, and the nutrient component of crops increases considerably thereupon.
2, the energy of taking in due to plant cell increases, and the plumpness of grain class, eggplant beans, berry plant grouting also improves thereupon, experiment showed, at rice plant of tillering stage foliage-spray " the residual remover of agriculture ", and the effective tiller of paddy rice increases by 2 ~ 4 strains; The flowering pustulation period in paddy rice uses, and the thousand kernel weight of paddy rice has increased by 0.26 ~ 0.8 gram; The fruit-setting rate of fruits and solanaceous vegetables can improve 8 ~ 10%, and crop yield generally improves 6 ~ 8%, and paddy rice husk rice yield improves 1.5 ~ 2%.
3, most importantly, after being absorbed by plant corpus, " the residual remover of agriculture " contained inorganic selenium changed into Organic Selenium, contain the amino acid of selenium, because the amino acid containing selenium is hybrid ion, in amino acid molecular, contain acid carboxyl and alkaline amino simultaneously, it is the electrolyte of both sexes, a kind of simultaneously with the ion of both positive and negative electric charge, therefore, under the adjusting of suitable ion (as increased calcium ion, other ion such as potassium ion, their entrained electric charges have been broken the charge balance containing selenoaminoacid, make it have and phenyl ring, long-chain hydrocarbon combination, destroy the ability of phenyl ring and long-chain hydrocarbon), thereby the aging of high-molecular hydrocarbons long-chain and phenyl ring and fracture have been accelerated, destroyed the molecular structure of agricultural chemicals, make remains of pesticide resolve into little group within the very short time (5 ~ 7 days), by poisonous become nontoxic.
Because this effect excites and improved the activity of plant self enzyme system simultaneously, the sp act producing after plant cell is active can also accelerate the rejection of cell to heavy metal.
" the residual remover of agriculture " is a kind of stable inorganic selenium and Chinese herbal medicine mixed solution, is not synthetics, and its mechanism of action is not chemical reaction, thus can not produce secondary pollution, safe.The fertile main component of Selenium in Soil is also inorganic selenium, and agricultural chemicals do not produce chemical reaction, both can mix and use with agricultural chemicals.
Through authoritative inspection organization testing identity, to use after " the residual remover of agriculture " preparation, agricultural product are secondary pollution absolutely not.
Beneficial effect
1, soil transformation: the heavy metals exceeding standard that the soil in plantation plot has natural Geological Reasons to cause, and the soil input throughout the year causing without the plantation of having holidays by turns too much, cross heavy metal, remains of pesticide complicated and that form and exceed standard, and above-mentioned two situations is compound.If heavy metal in soil (as lead) content >=5ppm, other harmful element arsenic, mercury, chromium, cadmium content surpass national planting soil standard, various remainss of pesticide are higher than Chinese planting soil agriculture residual standard, and this plot is for being used for many years chemical fertilizer, agricultural chemicals, again without the crops (this situation is more general in the East China of having a large population and a few land, South China) of crop rotation, intercropping;
In winter the previous year, the present invention is applied to crop root and carry out soil transformation.Remove the effect that agriculture is residual, reduce heavy metal, particularly for harmful element too high levels (lead >=8ppm in soil, when other harmful element is greater than standard value 2-5 times) effect is more outstanding, the agricultural product hazard residue of plantation is by European Union's standard test, all can reach ND, otherwise generally can only reach harmless standard, and must just can reach the ND of European Union standard at Second Year.
If add leached tea oil slag powder can kill the worm's ovum in soil, reduce damage by disease and insect and occur, reduced the frequency of utilization of agricultural chemicals.
2,, improve water quality: at the general pollution source of rural irrigation water, are wastewater from chemical industry, by using humic acid and the complexing of EM viable bacteria and reducing harmful element and content of beary metal in irrigation water, from source, guarantee the control of content of beary metal.
3, according to the habit of Different Crop, the stoste that proportioning is different, and face has been done strict regulations in time, facts have proved when the method is used, can use together with agricultural chemicals, but concentration and the time of noting using stoste, it can effectively reduce residual in crop of agricultural chemicals simultaneously.
Summary, the object of this invention is to provide a kind of completely newly, system, can eliminate remains of pesticide and reduce the method for agricultural product content of beary metal.The method is to soil melioration, water source purifying, and Different Crop is done differentiated treatment, when peasant normally uses agricultural chemicals effectively to control disease, reduce residue of pesticide and solve heavy metals exceeding standard problem, and every mu of cost only increases by 10 yuans.
