Description
Technical field
The present invention relates to a kind of manual work and increase selenium fertilizer; A kind of especially high nutrient substance composite selenic fertilizer of forming by selenium element, non-harmful organic materials-inorganic material and middle trace element; Mainly be applicable to Tea Production, it is fertile also to be suitable for using of paddy rice in large food crop, wheat, corn, potato class and fruit tree, Jiangsu cuisine.
Background technology
From last century 70
'It has been in the humans and animals vital movement since the requisite trace element that age is established selenium (Se); Clinical experimental medicine proves that constantly selenium is " bioelement "; If human body lacks selenium; Will cause the vitals functional disorder, can cause 40 surplus kind of disease: cancer, coronary heart disease, myocardosis, arteriosclerosis, mellitus, white blood disease, viral hepatitis etc.
Yet about 42 countries in the whole world are in and lack the selenium status.China is similar with the U.S., and a scarce selenium band is arranged from northeast to southwest, and it is low selenium or scarce selenium district that there is 72% county in China.Practice shows that in the proportion of crop planting process, increasing selenium is the most direct, convenient, cheap and good-quality method.
Selenium is a kind of good antioxidant, is the important component part (selenium and protein bound performance antioxygenation) of Selenoperoxidase (GPX), and its resistance of oxidation is higher 500 times than VE.Big quantity research proves that selenium has the effect that tumour takes place and develops that suppresses, and the low person's poor prognosis of selenium content in the tumour patient blood is found in clinical observation, is prone to recur and transfer.Selenium synthesizes the non-program of strong carcinogen-aflatoxin B1 (AFB1) inductive white corpuscle DNA has blocking effect.Selenium can stop hepatitis B patient to develop into liver cancer.China physician goes through the liver cancer district occurred frequently sick investigation discovery of learning in vogue in 16 years in setting jade: the selenium content that the liver cancer district occurred frequently is lived in people's blood all is lower than the low district of sending out of liver cancer, and onset of liver cancer rate and blood selenium degree are negative correlation; And mend the test of selenium anti-cancer in Qidong, Jiangsu, and mend selenium liver cancer generation ratio is descended, liver cancer person's family history sickness rate is descended.The U.S., Holland, Finland and Chinese science man find that the blood selenium degree of malignant tumor patient is lower than healthy subjects.There is stronger resistance of oxidation in selenium, can the inhibition of screening property and kill and wound cancer cells, and strengthen body immunity, and can lower the body injury that chemotherapy and radiation causes, improve tolerance to radiotherapy, chemotherapy.Selenium preparation all has the cancer of internal organs such as liver, oesophagus, stomach, colon, bladder, mammary gland, prostate gland, ovary and white blood disease etc. and significantly prevents and treatment effect.Selenium is referred to as the anticancer king in the body trace element by scientist.
Selenium to regulate immunologic function, anti-ageing and prevention cardiovascular and cerebrovascular diseases has good action.
Selenium can be regulated immunologic function.The effect that VC, Zn and VE regulate immunologic function is indirect, and selenium mediator body immunity function also has a kind of special function except that indirect action: selenium suddenlys change through preventing virogene, thereby suppresses the pathogenic of virus.This function is that other has the micro-nutrients of immunoloregulation function unexistent, and promptly selenium is unique nutrient substance that can directly suppress virus infection.
" free radical theory " of old and feeble problem gains universal acceptance at present, and what promptly constantly produce in the cellular process has the very radical and a lipoperoxide of strong biological activity, is the principal element that causes that histocyte is old and feeble; And intravital superoxide-dismutase of people (SOD) and Selenoperoxidase materials such as (GSHPX) can be removed radical too much in the body, reduce intravital lipoperoxide.Selenocystein is the activity centre of Selenoperoxidase, participates in oxidation and energy metabolism, plays crucial effect in many-sides such as regulating immunity, resistance virus mutation.Do not have selenium, just do not have peroxidase; Selenium content is few, and peroxidase activity just descends, and radical is just unbridled.Increase selenium and strengthen the removing radical, thereby reach the purpose of delaying human body organ senescence.Research shows, selenium and other element combined action, and the effectiveness of removing radical is wanted high hundreds of, several thousand times.
Scarce selenium is one of important factor that causes heart disease.Selenium is the important factor that links heart function, and the heart human body is had protection and repairing effect.Human body blood selenium degree is low, can cause removing in the body hypofunction of radical, and the fatty acid peroxidase thing in the blood is piled up; The function of myocardial cell membrane is damaged, the vessel wall thickening, blood vessel elasticity is poor; Rate of blood flow is slack-off, send the oxygen function reduction, thereby brings out cardiovascular and cerebrovascular diseases.Germany scientist once to hundreds of name suffer from coronary sclerosis, cardiac muscle suffocates and hypertensive patient's investigation draws: the intravital selenium content of these patients proves that than healthy subjects much less selenium content and cardiovascular diseases are inverse ratio.The investigation of the portion of the U.S. shows, lacks the number of dying from myocardosis, apoplexy and other relevant high blood pressure disease in the selenium area in the food than rich selenium area Senior Three times.Science is mended selenium all has better effects to preventing cardiovascular and cerebrovascular diseases, hypertension, arteriosclerosis.Adopted selenium to cure some heart trouble at present, obtained good therapeutic action as treat stenocardia, myocardial infarction, coronary heart disease etc. with selenium.
In addition; Scarce selenium is directly related in Keshan disease, big joint, ammonia poisoning, gastritis, cataract, hypertension, hyperlipidemia, ephritis, the deficiency of blood, great insomnia, stomatocace, immunologic hypofunction and the human body, and it is remarkable that these patients are taken the organoselenium result of treatment.
Selenium still is the defence agent of some heavy metal.Experiment finds that selenium has resistant function to cadmium, mercury, arsenic etc., but these metallic elements of antagonism get into human body.
The present invention is to be the center to increase selenium, and adds the middle trace element of increasing crop yield key element.
Over more than 100 year, N, P, K major fertilizer elements play leading role on increasing crop yield, but to the middle and later periods in last century; Scientist and peasant household all find; Only a large amount of N, P, K fertilizer of using not only do not increase production the underproduction on the contrary, and then find; These macroelement fertilizer are under excessive use, and its utilization ratio only reaches 30%.Scientist has found micro-production-increasing function in exploration, found the vital role of moderate-element raising the output then, and draws " bucket effect " and say.In fact, the amount of application of N, P, K sharply increases over more than 100 year, and the middle trace element of constantly being taken away by plant does not simultaneously obtain the supply of system.Consistent recognizing in the micro-element nutrition academic exchange conference in beginning of this century China first: the shortage of trace element in 21 century calcium, magnesium, boron, zinc, the iron etc. has become one of Chinese agriculture raising the output major obstacle.
Owing to the metallic element in the middle trace element (Ca, Mg, Fe, Cu, Mn, Zn) is prone to lose efficacy with the carbonate and the phosphate radical generation chemical reaction of soil, even if in fertilizer, allocate the middle micro element of q.s into, farm crop also can't absorb by institute's allocation ratio.In addition, the validity of trace element during soil pH value, weather etc. also influence.Therefore, need the centering trace element to carry out chelating, to protect its validity.Sequestrant is existing multiple, and effective have amino acid, EDTA and an EDDHA etc.Abundant because of organic substance of the present invention, the chelating effect is arranged, granulated in addition protection has constituted the micro-multiple protective of centering.
The occurrence patterns of selenium has 6 kinds in the soil: selenium element, selenium oxide, sodium selenate, Sodium Selenite, organoselenium, and volatilization selenium.The chemical bond of selenium has Se
4+, Se
2-, Se
6+, have human to experiment showed, Se in the tealeaves
4+Account for the 3.89%-14.17% of total selenium amount, Se
2-Content is 87.13%-96.11%, Se
6+Do not exist in the tealeaves.
According to research, easy to be fixing rapidly after selenium is manured into soil by sesquioxide in the soil (iron, aluminium), especially at acid soil, Se
4+Absorption fixing strong, the bioavailability of selenium is low, the tealeaves selenium content increases slowly.For this reason, a micro-component of selenium as fertilizer sources is necessary for it environment that fully discharges is set.After selenium got into soil, its biological effectiveness and soil ulmin were tight association, through mensuration, and the soil that organic content is high, water soluble selenium is relevant significantly with the selenium of plant absorbing, and the low soil of organic content, then dependency is very poor.Tealeaves is increased the selenium Study on Technology to be proved, tealeaves selenium and soil available selenium are remarkable positive correlation, with lateral reactivity attitude selenium and slow attitude selenium higher dependency is arranged also.Available state selenium receives the soil organic matter content considerable influence equally, also receives the influence (clay mainly influences full selenium of soil and residual form selenium content) of soil clay particle content.Someone with soil ulmin+selenium+other micronutrient element, can improve the validity of selenium in the different schemes of the fertile configuration of selenium; Test shows has the participation of soil ulmin, can form stable combination solution; Avoided being fixed and precipitating of selenium element; Be prone to be transformed, overcome that singly to execute selenium content in inorganic selenium consumption and the agricultural-food uncontrollable and to the spinoff (inorganic selenium directly gets into soil and water body, then causes the pollution of soil and water body when excessive) of environment by plant absorbing.With the continuous extraction classification technique 9 kinds of different propertiess of China and the horizontal soil of selenium discovered that quick-acting selenium and slow selenium can be used for weighing the validity of Selenium in Soil, the rich scarce degree that sum of the two can be used for estimating the situation of Selenium in Soil and predicts selenium.The storage of selenium in the soil shows that through the analytical results to the combining form of selenium in Yunnan, 42 soil layers of 14 sections in Sichuan and Zhejiang selenium is mainly composed and existed in soil ulmin and the remaining lattice.Soil organic selenium can be divided into the two portions with humic acid and fulvic acid combined.In on average, humic acid combined selenium accounts for 34% of organoselenium, and fulvic acid combined selenium accounts for 66%; To California, USA and to China the discovering of the organoselenium in several kinds of soil of moistening half humid region, organic selenium is also mainly composed and is stored in the fulvic acid.And the ratio that lacks humic acid combined selenium in the selenium soil organic attitude selenium is generally all higher.The selenium of the selenium of humic acid component and fulvic acid component all mainly is the form appearance with selenoamino acid, and some is similar.In soil extract, organoselenium can account for about 50% of water soluble selenium, and this being distributed in the soil of selenium is stable.
Selenium fertilizer of the present invention be the people for increasing selenium, be to lack selenium soil to add the selenium element, to make selenium fertile in order to lack the selenium area, for farm crop (comprising tealeaves) increase selemium nutrition, with most convenient, cheapness, directly mode is a body-care.And, according to being fruitful of selenium and soil correlative study, selenium and the middle trace element of mutually promoting, selenium and the organic-inorganic that shields, with inner complex, to be combined into present high available state selenium fertile with constitution etc.
With disclosed nearly 50 selenium fertilizer formulas (comprising solid-state and liquid) comparison at present, ignored by artificial for the validity of selenium.What is the available state of selenium? Being exactly that " selenium " in your the selenium fertilizer obtains protection in edatope, activity is arranged, is effectively, can high bioavailability (>90%) be arranged by the plant absorbing utilization.In fact, the selenium in being manured into soil under acidic conditions, is fixed rapidly by sesquioxide (iron, aluminium), wherein Se especially
4+Absorption fixing strong; In addition, clay mineral, the soil organism etc. also adsorb selenium or make it become complex compound (selenium and soil clay particle content, organic content are proportionate); Also have inorganic selenium residual in the soil, small molecules organoselenium and volatilization selenium etc. to subject to leaching loss.And under the high condition of soil pH value (alkaline condition), the pH value is high more, and the activity of selenium is big more, and leaching loss is just serious more.Total is that selenium has been fixed, and has run off, and makes the absorbent selenium amount of plant few and slow, makes the bioavailability of selenium low.Here it is, and some selenium are fertile, and reality is not seen the reason that increases the selenium effect.The usefulness multilayer resist technology of patent novelty so of the present invention makes the selenium in being manured into soil become available state.One of which, selenium of the present invention is fertile, and a large amount of organic matters are arranged in the prescription, makes selenium become small molecules organoselenium (Se through fermentation
2-); Its two, selenium is processed chelating selenium, or processes two inner complexs, selenium effectively is protected; Its three, selenium fertilizer of the present invention is that a kind of tunicary particle is fertile, also is effectively one of protection; Its four, there is mutual promoting action in the special middle trace element that has added chelating in the selenium fertilizer of the present invention between them, has also improved their activity in soil.First kind of protection for selenium has the scholar to be referred to as " internal adsorption ".In fact, second and third, four kinds of protections also are a kind of " internal adsorption "!
It is sure increasing that selenium makes tealeaves raising the output and improve quality, only a routine underproduction or other reason.Because of being fixed of selenium applies selenium in a large number, then cause environmental pollution to have case.
