Description
Technical field
The invention belongs to proportion of crop planting fields, and in particular to a kind of special seedling medium containing selenium of selenium sand melon and its production are rich
The method of selenium selenium sand melon.
Background technology
Selenium, symbol of element Se are a kind of micro elements needed by human, are the work of glutathione peroxidase (GSH-Px)
Property center there is anticancer, anti-aging (anti-oxidant) and improve the immunity of the human body, the biological characteristics such as antagonism heavy metal.In it is state-run
Supporting association's recommendation, daily selenium intake is 50-200 micrograms per capita.But it is micro- that the day selenium intake of present China adult only has 26-32
Gram, therefore, the bad situation of selemium nutrition is in China's generally existing.The data that WHO is announced shows that the whole world has a country more than 40 to belong to
Low selenium or selenium deficiency area.Selenium in food chain is mainly derived from soil, and Se content is unevenly distributed in the soil of different regions.I
There is Keshan in the state-owned 72% low selenium in county (city) or selenium deficiency, the serious selenium deficiency area such as Heilungkiang, the Inner Mongol, Gansu, Qinghai, Sichuan
Disease, Kaschin-Beck disease occur, certain cancers district occurred frequently (such as Jiangsu Qidong City) areas Ye Shudixi.It is real according to the poor selenium soil clue in part
Targetedly selenium-rich work is applied and carried out, the important side that the Se content level in food chain is agricultural production research is optimized
To.
The Se content of crops is generally by crop varieties, agronomy management measure, soil Se content and certain physical and chemical indexes etc.
The influence of factor.China belongs to the country of serious selenium deficiency, and there are about 70% national territorial areas to belong to selenium deficiency area in the whole nation.Soil
Selenium deficiency directly results in the deficiency of Se content in most of regional crops so that China a big chunk crowd is in selenium battalion
Support deficiency state.Watermelon has long cultivation and food custom as a kind of extensive consumption, fruit suitable for all ages in China.
The watermelon Se content that common area produces is generally below 1 micro- g kg, and people are very limited from the selenium wherein taken in, so it is right
It carries out selenium nutrition-intensified being a kind of preferable approach of enhancing human body Se nourishment level.
The higher area of some soil Se contents of China directly plantation watermelon can produce Se content than common regional selenium
The higher watermelon of content.But since there is also region inhomogeneity, this producers for Se content distribution in selenium-enriched area soil
Formula is quantitative to the Se content in watermelon controllable more difficult, it is possible to be more than the related limit standard of country, there are region limitation and contain
Variability is measured, large-scale standardized production is unfavorable for.
《Selenium-enriched watermelon greenhouse pollution-free cultivation technique》(Liu Su chastity Agriculture of Anhui science .2006,34 (15)：3660-
3662) a kind of method spraying blade with organic selenium zinc nutrient solution to obtain selenium-enriched watermelon is disclosed in, but the method easily causes
Inorganic selenium largely remains, and inorganic selenium has apparent toxic action, safety relatively low organism；It is nuisanceless, green and have simultaneously
Machine agricultural product are provided against to be sprayed using the chemical synthesis preparation that do not recommend, and therefore, the technology of spraying cannot be in high-quality and height
It is used in the agricultural product production of added value.
Chinese invention patent " a method of improving selenium-content of fruit " (application number：95109479.3) disclose one kind and carry
The method of high selenium-content of fruit, main points are to use high pressure trunk injector into trunk by 100kg in 15~45 days before fruit picking
Fresh weight injects liquid, i.e. 20~66mL of sodium selenite or selenic acid sodium water solution of 0.1~2ppm concentration.Due to general Selenium By The Plants
There are tenability limit, there are burn seedlings risks for watermelon vine for the method, and practical operation is more difficult.
Chinese invention patent " a kind of biological selenium-rich fertilizer agent and preparation method thereof " (application number：200910248732.1) open
A kind of method being mixed in a certain ratio production biological selenium-rich fertilizer agent using sodium selenite and complex rare-earth.But this biology
Whether selenium-rich fertilizer agent is effective to watermelon, and can the Se content for the different batches watermelon that produced keep stablizing on the knees of the gods.Patent
" watermelon rich in organic Se and its production method " (application number 201010580221.2) discloses a kind of production of watermelon rich in organic Se
Method cultivates selenium-enriched watermelon, but selenium during undisclosed selenium fertilizer Se content and cultivating watermelon by way of soil application selenium
Amount of application.
In addition, patent " selenium-enriched watermelon seedling medium and preparation method thereof " (application number 201610790976.2) discloses one
Kind selenium-enriched watermelon seedling medium, complicated component, and without open matrix Se content parameter, and its selenium-rich effect is limited, for selenium
The selenium-rich effect of sand melon can not also be learnt.
It is the sandy loam region of height above sea level 1200m to 1800m to press sand watermelon Main Cultivation environment, and the Regional Precipitation is few, soil
Barren and soil water-retaining, fertilizer-preserving ability are poor.Zhongweiof Ningxia, northwest China area is famous Ya Sha cultivating watermelons area of China, Zhongweiof Ningxia, northwest China city
Pressure sand watermelon because being also known as " centre halfback's selenium sand melon " rich in health elements " selenium ", be known as " gobi watermelon ", " west in stone seam
Melon ", is Ningxia Hui Autonomous Region Zhongwei City specialty, the selenium sand melon of centre halfback and in 2007, obtains Chinese geography sign protection agricultural production
Product certification.The centre halfback Fragrance Hill bases Xi Shagua account for about the ring Xiangshan District of 1/3 area of Zhongwei City, are located in Mongolian plat and loess plateau
Zone of transition, for annual precipitation less than 180 millimeters, evaporation capacity is but 2400 millimeters, belongs to most arid one of the place of China, by
In this area, soil Se content is higher, is selenium-enriched area, but the watermelon Se content of its output is only 5 micro- g kgs.At present also simultaneously
The production method of selenium sand melon Special selenium fertilizer and selenium-rich selenium sand melon is not had been reported that.
Therefore, the technology that the production selenium-rich selenium sand melon of regional special weather and environmental condition is cultivated for selenium sand melon also has
It waits excavating.
