Description
Technical field
The present invention relates to fruit, particularly a kind of organic selenium-rich eggplant, and the production method of this kind organic selenium-rich eggplant belong to agricultural fertilizer and horticultural gardening technical field.
Background technology
Eggplant, the Solanaceae nightshade.Domestic planting area is extensive, is indispensable a kind of important vegetables during people live.Eggplant is nutritious, contains multiple nutritional components such as protein, fat, carbohydrate, vitamin and calcium, phosphorus, iron.The foreign study result shows that eggplant is anticancer rival, can prevent and treat cancer of the stomach: the solanine that it contains, can suppress the propagation of digestive system tumor.In addition, the eggplant effect of cancer heat of clearing up and discharging in addition.Eggplant also contains multiple alkaloids such as choline, trigonelline, stachydrine.Eggplant also can be anti-ageing: contain vitamin E, prevent hemorrhage and anti-senescence function, often eat eggplant, can make the low cholesterol level in the blood of keeping, delaying human body caducity is had positive meaning.In the cultivation agronomy of eggplant, the transplanting planting technology of seedling is widely used.
Selenium, symbol of element Se is a kind of micro elements needed by human, is the activated centre of glutathione peroxidase (GSH-Px). has anticancer, anti-ageing (anti-oxidant) and improves biological propertyes such as body immunity, antagonism heavy metal.Selenium in the food chain is mainly derived from soil.Se content skewness in the soil of different regions, the local poor selenium soil clue of foundation is implemented and is carried out rich targetedly selenium work, and the Se content level of optimizing in the food chain is an important directions of agricultural production research.Chinese Soclety of Nutrition recommends that every day, selenium intake was the 50-250 microgram per capita.But China adult's day selenium intake only has the 26-32 microgram now, and therefore, the selemium nutrition condition of poor is at China's ubiquity.There are 72% low selenium in county (city) or scarce selenium in China, and Heilungkiang, the Inner Mongol, Gansu, Qinghai, Sichuan etc. seriously lack the selenium area has Keshan disease, Kaschin-Beck disease to take place, and certain cancers district occurred frequently (as the Jiangsu Qidong City) also belongs to low selenium district.The data that WHO announces shows that the whole world has more than 40 country to belong to low selenium or scarce selenium area.
Selenium in the vegetables is divided into inorganic selenium and organic selenium two big classes: the former comprises selenate, selenite etc., and inorganic selenium assimilation effect for humans and animals is poor, and risk of toxicity is big, and improper use very easily causes selenosis; The latter mainly comprises forms such as seleno-amino acids, seleno albumen, selenium polysaccharide, good absorbing effect concerning humans and animals, and toxicity is little, is more suitable for mending the requirement of selenium.Se-rich farm products is a human body Selenium Supplement element effective way, and therefore, technique of enriched selenium is scientists study exploitation and the hot fields that is put to actual production.The critical role of vegetables in resident's dietary structure determined its Se content level that whole people's selemium nutrition situation is had very big influence.The present domestic rich selenium vegetables mode of production mainly contains following several:
A kind of is to spray sodium selenite solution before the vegetables results, reaches rich selenium level thereby make vegetables can absorb sodium selenite rapidly.As Chinese patent CN1594234A, CN101182246A etc.Method is simple for this, and shortcoming is that the inorganic selenium residual quantity is very big in the final vegetables, is unfavorable for the absorption of human body utilization, and inorganic selenium has tangible toxic action to body.
The 2nd, at the stronger vegetable variety of natural selenium-rich area plantation accumulation ability, but, can't quantitatively control Se content in the vegetables because there is areal variation in rich selenium area Selenium in Soil content, might surpass national limit standard.There is the region limitation, is unfavorable for large-scale standardized production.
The 3rd, in vegetable growth mid-term, apply selenium fertilizer in the soil, as article: " execute selenium and eggplant is absorbed the influence that transforms selenium and quality " (plant nutrition and fertilizer journal, 2004,10 (3): adopt the method for sodium selenite solution pouring to produce rich selenium eggplant 298-301.), but along with the rising of sodium selenite solution concentration, the organic selenium accounting reduces in the eggplant, organic selenium ratio only 49%.As Chinese patent CN101734971A.The method can guarantee that vegetables reach rich selenium standard, improves the vegetables organic selenium content.But, can not guarantee that its nutritional agents is fully absorbed by vegetables because adopt plant growth land for growing field crops in mid-term root to execute.Most selenium can be retained in the soil in the nutritional agents, has reduced the availability of selenium additive.The selenium of leaving over increases the burden of selenium in soil and the water body environment along with rainwater or irrigation water run off, and long-term use easily causes selenium contamination.But relevant known technology is all established and is not related to the eggplant that is rich in organic selenium, and the production method of specifically cultivating the organic selenium-rich eggplant.
