Description
Technical field
The invention belongs to the Cultivating techniques field of functional rice, be specifically related to a kind of breeding method of selenium-rich rice.
Background technology
Rice is one of staple food of the mankind, and according to modern nutriology analysis, rice contains protein, fat, vitamin B1, A, E and several mineral materials.Carbohydrate containing about 75% in rice, protein 7%-8%; Fat 1.3%-1.8%, and containing abundant B family vitamin etc.Carbohydrate in rice mainly starch, contained protein mainly oryzenin, next is oryzenin and globulin, the biological value of its protein and amino acid whose composition are all high than cereal crops such as wheat, barley, millet, corns, digestibility 66.8%-83.1% is also one higher in grain protein.
Edible rice has higher nutritive value.Black rice wherein, glutinous rice, the seed of Job's tears, millet, polished rice, brown rice have health-care efficacy, and the health-care efficacy of general rice is very poor.
At present, a kind of selenium-rich rice due to its health-care efficacy very remarkable.Meanwhile, by eat rice mend selenium oneself be acknowledged as the world today the most directly, effectively, economical, safe by selenium approach.Selenium is decided to be by the World Health Organization and Chinese Medical Association the third-largest micronutrient health care element that 21st century must mend after iodine, zinc, and selenium plays anti-oxidant in human body, delays senility, removing toxic substances, toxin expelling, antipollution, protects liver and hemopoietic system; Prevent cell senescence, reduce cardiovascular and cerebrovascular disease, prevention canceration, improves the multiple functions such as immunity.So selenium-rich rice liking deeply by people, market prospects are very good.
And current, selenium-rich rice is produced by the place that some soil selenium-containing amounts are abundant, and the paddy rice of producing is naturally containing selenium.And only have the Liuzhi Special Region (one of three large natural selenium-rich areas that China is famous, belong to north subtropical monsoon climate here, and advantageous natural advantage is extremely conducive to the production of natural selenium-rich rice) being in western part, Guizhou Province at present.Therefore, the production of selenium-rich rice has been limited to.
Summary of the invention
Object of the present invention is exactly overcome deficiency that existing selenium-rich rice produces and provide the breeding method of brand-new a kind of selenium-rich rice.Specifically comprise: select Bath horse base of a fruit rice varieties as breeding provenance, select blade face organic selenium fertilizer fertile as selenium, enter into booting stage and the pustulation period respectively sprays a selenium fertilizer at paddy growth.By implementing the present invention, overcome the defect that place that selenium-rich rice only enriches by soil selenium-containing amount could produce selenium-rich rice.Meanwhile, by spray spraying Se fertilizer produce Rice enriched-Se selenium content more taller.In addition, by implementing the present invention, be the high-quality rice that general rice becomes high-quality, health care, people can be made to obtain mending selenium in the middle of habitual feed, and rice is significantly rised in value, benefit also significantly improves.
Described selenium is divided into two kinds in natural existing way: inorganic selenium and Organic Selenium.Inorganic selenium refers generally to sodium selenite and sodium selenate, obtaining containing the mineral dust by product of selenium element from metal mineral reserves.The latter is that selenium is combined into by biological transformation and amino acid, generally exists with the form of selenomethionine.Selenium is the trace element of needed by human, and selenium to distribute at the earth's surface be extremely unbalanced, China about has 72% area to lack selenium, and some areas of 15 provinces, cities and autonomous regions particularly from northeast to southwest constitute in " poor selenium area ".Therefore, Chinese Famous nutritionist Yu Ruo wood proposes, and [1] China will do a good job of it and mend selenium work as grabbing and enriching the iodine.All at 0.2ppm [1] below, the selenium content of dry oyster, dried shrimps is the highest for the selenium content of normal food, and also less than 3ppm, the selenium content of food bacterium that is wild and that cultivate according to a conventional method generally can not more than 1ppm.Organic Selenium generally exists with selenomethionine form, follows the metabolism of Methionine metabolism approach, participates in the synthesis of albumen, easily stores in tissue, absorbs; Can be immediately used by the body rapidly after being absorbed by the body, effectively improve blood in human body in selenium situation.As everybody knows, the earth and tellurian all things on earth are all made up of chemical element.As the intelligent part of the universe in chemistry on the earth and organic evolution, the chemical composition of human body is all roughly the same with the earth on quality and quantity, almost containing all elements that epigeosphere exists.How many these elements, be divided into macroelement and trace element by its content.Macroelement comprises 11 kinds, oxygen, carbon, hydrogen, nitrogen, calcium, sulphur, phosphorus, sodium, potassium, chlorine, magnesium etc., and the basic structure of their composition human bodies, accounts for 99.95% of human body weight, and the water (H2O) that wherein hydrogen and oxygen combine just accounts for human total weight's 65%.More than 100 year after selenium was found from 1817, be treated as toxic element always.But nineteen fifty-seven finds that it is a kind of protective factors preventing trophism hepatonecrosis; Within 1973, find that selenium is the active component of glutathione peroxidase; China in 1980 finds that selenium deficiency is the Important cause of disease of Keshan disease.People are familiar with gradually, and the same with protein as picked-up starch, we must take in appropriate selenium every day.In " every day meals Middle nutrition element supply and the dietary guidelines of China " that Chinese Soclety of Nutrition in 1988 is recommended, selenium and energy, protein, several important vitamin and calcium, iron, zinc, iodine etc. be listed as 15 kinds every day meals essential nutrients.Micro-Science Research Association vice president professor Liang Dongdong of China introduces, and selenium is the trace element of needed by human, and organism organic selenium safety is high, and be easily absorbed by the body utilization, and benefit selenium efficiency is high, welcome especially.With the grafting of selenium element in rice, then allowing people obtain mending selenium in the middle of habitual feed, is a kind of extraordinary method.Selenium-rich rice is to the effect of human body: 1, anti-oxidant, anti-ageing: selenium can delay senility, and reduces the phenomenons such as depressed, tired, improves eyesight, prevents and treats cataract, fundamentally improve the quality of life of the elderly.
2, protection, repair cell: selenium plays the peroxide produced in organism metabolism activity in whole cytoplasm to be cleared up and reduction, and Cell protection membrane structure is from the infringement of peroxide.
3, erythrocytic oxygen carrying capacity is improved: the red blood cell in selenium protection blood; haemoglobin in red blood cell would not be oxidized; its oxygen carrying capacity is strengthened, rapidly the oxygen of abundance can be brought each cell of body, make each cell exercise normal function.
4, body immunity is improved: selenium can strengthen the recognizability of immune system to pathology in the virus in human body, foreign matter and body, improve the antibody horizontal in the antibody synthesis of immune β cell, the propagation of T cell, blood, make the engulfing of macrophage, sterilizing ability improves 2 times.
5, removing toxic substances, toxin expelling, antipollution: selenium is as electronegative nonmetallic ion, can be combined with positively charged harmful metal ion in human body and directly excrete, thoroughly clear up the toxicity of metal ion, eliminate poisoning symptom, play toxin expelling, removing toxic substances, resistant to pollution effect, selenium is to resistant to pollution " natural antipoison ".
6, canceration is prevented: selenium is the kill agent of cancer cell, selenium can block the important energy source of two of cancer cell, improve the level of the sweet acid of ring gland in cancer cell, form the environment of inhibition cancer cell division and propagation in vivo, selenium can also lower the toxic and side effect of Radiotherapy chemotherapy, obviously alleviates the severe pain of patients with advanced cancer.
7, protect cardiovascular and cerebrovascular: the stability of selenium participation protective cell membrane and normal permeability, suppress the peroxidization of lipid, eliminate the toxic action of free radical, thus the normal configuration of protection cardiac muscle, metabolism and function.
8, hypoglycemic: research finds, diabetic's blood selenium mean value is starkly lower than Healthy People, clothes can improve the symptom of diabetes patient containing selenium product, and selenium can also improve the glucose tolerance of diabetes patient; In recent years research shows, selenium also has the insulin mimetic effect such as reduction blood sugar and regulation and control insulin metabolism process;
9, male sexual function is regulated: when external scientist finds selenium concentration 0.050-0.069 μ g/ml in refining, nitric oxide is in optimum state; In refining, selenium concentration and blood selenium are proportionate, and are proportionate with pregnancy rate.
