Background technology
The outstanding problem that grain, fruit, the vegetables of selling in the market all exist pesticide residue, heavy metal and harmful element to exceed standard largely, a succession of food acute poisoning incident, the life that has jeopardized people is with healthy! Caused showing great attention to of society, national top leader is weighed down with anxieties for this reason." bread is the staff of life, and food is with An Weixian ", reducing and eliminating pesticide residue has become the new trend of China's agricultural sound development, the new expectation of compatriots' food safety.
21st century people expectation no more than having relieved, healthy food.After country's " food safety method " promulgation; The consciousness of food safety is rooted in the hearts of the people, " bread is the staff of life, and food is with An Weixian "; People call " nuisanceless ", " green ", " organic " food can really put on dining table " eat relievedly, afford to eat ".Therefore, " great Bo Nongke " is devoted to the new technology researched and developed always, be intended to eliminate the agricultural chemicals medicine residual, reduce heavy metal content, improve quality of agricultural product.This technological core value is: compare with organic production, it is under the situation that does not change original farm crop production model, realizes the target that the high quality agricultural products cost reduces, and is convenient to big area, many kinds are extensively promoted.
Selenium is fertile to cause that with the ability that reduces heavy metal people pay attention to as eliminating pesticide residue day by day, but in actually operating, particularly be summer and autumn the opportunity of Spraying Se-fertilizer; Rainwater dew is more, and selenium fertilizer is short in the crop blade face residence time, and loss of effective components surpasses more than 50%; And be prone to diluted or partial concn is excessive; Even if absorbed part, also because effective acting time of short duration (being generally 15 days), it is undesirable to fall agricultural residual effect fruit.The present invention provides a kind of slowly-releasing (reach 30-45 days action period) and reduces selenium fertilizer of blade face loss and preparation method thereof, to improve the fertile deteriorating pesticide residue effect of selenium for addressing the above problem.
Summary of the invention
Goal of the invention
The object of the present invention is to provide a kind of slowly-releasing selenium fertile, long-acting the playing a role of the fertile ability of this selenium do not brought the material of new contaminate environment again into.
Technical scheme
A kind of durable inorganic compound selenium fertilizer of degradable remains of pesticide is characterized in that in weight part, and its prescription is the fertile 80-97 part of inorganic compounding selenium, sustained release dosage 1-3 part, and agent 3-5 part, 1000 parts in water are detained in the blade face.
Described inorganic compounding selenium fertilizer is mixed by weight 6:4:0.1 by potassium selenite, Sodium Selenite, calcium hydroxide.
It is that sugar is burnt that agent is detained on described blade face.
Described sustained release dosage is a sucrose fatty ester.
A kind of preparation method of durable inorganic compound selenium fertilizer of degradable remains of pesticide is characterized in that: in weight part, realize as follows: with sustained release dosage 1-3 part, the fertile 80-97 part of inorganic compounding selenium; Agent 3-5 part is detained on the blade face; 1-3 parts of thorough mixing of sustained release dosage add 1000 parts of mixing of water, finished product.
The present invention can be applied to crops such as tealeaves, vegetables, fruit, grain.
Beneficial effect:
1, the sustained release dosage of the present invention's employing is the sucrose-fatty ester solution.Wherein selenium fertilizer slowly discharges thereupon, thereby realizes the effect of slowly-releasing, and it can effectively continue to reduce pesticide residue in 45 days, increases 2-3 doubly than the fertile validity period of general selenium.The delay agent can reduce the rate of loss of selenium fertile 50%, further strengthens the fertile effect of selenium.
2, reduce pesticide residue.During farm crop flowering grouting (result), crop carries out the transition to the stage that reproducibility is grown by the trophicity growth just, is the most vigorous period of crop cell vitality at this moment.The present invention is sprayed on the blade face; The selenium element gets into vegetable cell rapidly in the photosynthesis of plants process, and is active through the special physiological of irritation cell protease-producing, quickens the activity of vegetable cell; Quicken aging, the fracture of agricultural chemicals (high-molecular hydrocarbons) molecular chain; Make agricultural chemicals change structure in the short period of time and lose toxicity, resolve into natural fundamental element carbon and hydrogen, remove the harm of pesticide residue the mankind.The present invention's residual mechanism of farming of degrading is the process that physiological action after vegetable cell activates promotes physical and chemical effect.What this process embodied is the stechiology principle.And raw materials used inorganics and the natural plant extracts of being do not contain any chemical ingredients, so be not chemical principle, can not produce in " verivate " behind the chemical reaction.The present invention sees from practice; Through TE, under different time, different concns state, mix with various agricultural chemicals, do not produce Degradation mutually; So normally bring into play under the situation of drug effect not influencing agricultural chemicals; Through technical finesse of the present invention, get final product thorough degrading pesticide residues, and do not have the anxiety of secondary pollution.
3, reduce the absorption of farm crop to heavy metal in soil.Under the common activation of potassium, sodium, calcium ion; The reductibility that the selenium element is very strong, oxidisability and nucleophilicity are able to strengthen; Can generate polar links with some electron groups, can reduce like this with degrading pesticide in macromolecular mass, can combine with phenyl ring again; Obtain degraded product, thereby remove pesticide residue.Selenium atom still is one " soft base ", can form stable compound with transition metal ion etc. " soft acid ", and good counterweight metal degradation effect is arranged.
4, after the present invention handles, the root system that plant can reduce heavy metals such as lead absorbs, and can reduce the transmission of heavy metal in plant, particularly reduces its transmission to plant leaf bud and fruit, thus the content of harmful element in agricultural-food such as reduction heavy metal.This function perhaps to be planted in contaminated by heavy metals water source, the residual huge meaning that has falls in farm crop in the soil.
1, increases production, increases income, particularly to grouting type crop paddy rice, wheat and solanaceous vegetables.The characteristic of selenium salt can make the blade face pore the first transaction of a day's business rate of plant increase; Photon in the sunlight speeds up through pore; The photon that from sunlight, absorbs increases, and the energy that gets into plant materials increases, and changes into various nutritive substances of glucide and synthetic such as protein, amino acid is just many.Simultaneously, the present invention can increase the ability of plant leaf surface absorbed nitrogen element, has been equivalent to improve the ability of phytosynthesis nutritive element, makes increasing crop yield.With rice is example, and the increase of tillering, grouting are full, and usually the amplitude of raising the output is about 8%.
2, the present invention adopt depleted sugar Jiao be sugared slag as being detained agent, make sugared slag utilization of waste material, sugared slag itself contains a large amount of amino acid, carbohydrate can improve soil constitution, reaches the effect of raising the output.
3, reduce the amount of application of chemical fertilizer in soil, reduce cost.
