Description

A kind of production method of rich selenium dragon fruit

Technical field

The invention belongs to a kind of production of fruit trees management new technical field, be specifically related to a kind of production method of rich selenium dragon fruit.

Background technology

Selenium is a kind of chemical element, and chemical symbol is Se, a kind of nonmetal.The required nutritive element of light-sensitive material, electrolytic manganese industry catalyzer, animal body and the useful nutritive element etc. of plant can be used as.Selenium is also the trace element of needed by human.Selenium participates in multiple selenoenzyme and Selenonic protein in synthesized human.Its Glutathione Peroxidase, catalysis hydroperoxides or MDA change water or various alcohols in vivo, eliminate the biomembranous attack of radical pair, and protection biomembrane is from oxidative damage; Selenium participates in forming iodate thyroid gland amino acid and takes off iodine enzyme.Selenium can improve human immunity, promotes the synthesis of lymphocytic propagation and antibody and immunoglobulin.Selenium has kinds cancers such as colon cancer, cutaneum carcinoma, liver cancer, breast cancer and significantly suppresses and the effect of protection, and its mesostate methyl enol in body has stronger active anticancer.Therefore selenium be referred to as by scientist " king of anti-cancer " in body trace element.

Scientific circles' research finds, the nutrients such as selenium and vitamin E, allicin, linoleic acid, germanium, zinc have collaborative oxidation resistant effect, increases antioxidation activity.Meanwhile, selenium has the effect alleviating and alleviate heavy metal toxicity.The height of blood selenium level is closely bound up with the generation of cancer.A large amount of survey data explanations, a regional food and the height of Selenium in Soils content have direct relation with the incidence of disease of cancer, such as: the Se content in the food in this area and soil is high, the M & M of cancer is just low, otherwise, the cancer morbidity in this area and lethality are just high, the generation close relation of statement of facts selenium and cancer.

Science confirms: just because of the high anti-oxidation effect of " selenium ", and appropriate supplementary can playing prevents organ aging and pathology, delays senility, strengthens immunity, resist disease, resist toxic heavy metal, alleviate chemicotherapy side effect, cancer-resisting.

Meanwhile, selenium also has following effect:

(1) develop immunitypty: Organic Selenium can remove interior free yl, gets rid of vivotoxin, anti-oxidant, the generation that effectively can suppress lipid peroxide, prevents blood clot, remove cholesterol, strengthen immune function of human body;

(2) prevent diabetes: selenium is the active component forming glutathione peroxidase, and it can prevent beta Cell of islet Oxidative demage, make its function normal, promote sugared part metabolism, reduce blood sugar and glucose in urine, improve the symptom of diabetic;

(3) prevent cataract: retina due to contact computer radiate etc. more, subject to damage, selenium can protect retina, the fineness of reinforcing glass body, improves eyesight, prevents cataractous effect;

(4) cardiovascular and cerebrovascular disease is prevented: selenium is the important element maintaining heart normal function, to the effect that heart human body has protection and repairs.The reduction of human body blood selenium level, the hypofunction of scavenging free radicals in body can be caused, hazardous material deposition is caused to increase, blood pressure raises, vascular wall is thickening, blood vessel elasticity reduces, VPV is slack-off, send oxygen function reduction, thus the incidence of disease bringing out cardiovascular and cerebrovascular disease raises, but supply Se scientific has good effect to prevention cardiovascular and cerebrovascular disease, hypertension, arteriosclerosis etc.

Along with the quickening of modern life rhythm, the increasing of people's life stress, the health of people is in " sub-key health " state for a long time.Expert advice human body takes in selenium standard should be the most suitable with 240-260 microgram every day, sees that the selenium content depending merely on agricultural product itself can not meet human body needs far away with regard to this numeral.

Chinese Soclety of Nutrition did an investigation to 13 provinces and cities of China and showed, Coming-of-Age Day, average selenium intake was 26-32 microgram, and bottom line 50 microgram of recommending from Chinese Soclety of Nutrition is far apart.General vegetable food selenium content is lower.Therefore, exploiting economy, convenience, be applicable to long-term edible selenium-enriched food imperative.Selenium-rich rice, rich selenium walnut, rich selenium green pepper, selenium-enriched apple, mushroom with abundant selenium, rich selenium tomato ... the agricultural product such as grain, veterinary antibiotics being turned on " rich selenium " board quietly show city, seem very nearly the same with common agricultural quality, but the personal value is also higher than common agricultural a lot, and while winning to pay close attention to, its nutrient component also becomes the topic that consumer is concerned about.

And current, rich selenium dragon fruit has no relevant report.

Summary of the invention

Object of the present invention is just to provide the production method of brand-new a kind of rich selenium dragon fruit.Specifically comprise: when the dragon fruit florescence, fill with the selenium solution executed to according to quantity for every 7 ~ 10 days dragon fruit fruit tree; When dragon fruit fruit is shaped, within every 5 ~ 6 days, spray a selenium solution.By implementing the present invention, selenium raw material dosage is few, and therefore whole production process cost is low, but the dragon fruit produced not only rich in nutritive value, and Se content is high, makes common dragon fruit become functional fruit.Increase substantially the quality of dragon fruit, dragon fruit is along with increment, and benefit is very remarkable.

The present invention is achieved through the following technical solutions:

A production method for rich selenium dragon fruit, technical scheme be the dragon fruit fruit growth cycle stage by stage give dragon fruit fruit tree fill with execute selenium solution and give dragon fruit fruit Spraying Se solution.
