Background technology
The challenge that China is increased by population, soil reduces is the severeest, and population accounts for the 1/4 of total world population, but is had
Cultivated area be only the 1/7 of world's total area under cultivation, according to statistics in 2000, whole nation per capita cultivated land was only 0.01 hm2, without soil
Cultivation can provide and exceed normal soil and cultivate the product quantity of several times even more than ten times, available sandy beach, the barren land such as saline and alkaline
Produce agricultural product, lay a solid foundation for food safety security system.China is the country that water quality resource is the poorest, is listed in the world
One of Shang13Ge Pin land that abounds in rivers and lakes, whole nation water resources ownership per capita is only the 1/4 of world's per capita share, the annual hydropenia about 300 of agricultural
Hundred million m3, soilless culture, as the effective means of water-saving agriculture, will play its important effect at drought and water-scarce area.China's facility
Cultivation development is rapid, to become many areas agricultural and get rich, the effective means of growth of agricultural efficiency, but the result of cultivated since long, facility
Soil cultivation continuous cropping obstacle increasingly sharpens, and soilless culture plays as the effective means of radical cure soil cultivation continuous cropping obstacle

The most important.Selenium can improve Peroxidase Activity in Plant, strengthens the oxidation resistance in plant body, thus improves plant
Resistance and defying age ability, Selenium Supplement element during crop culture, not only can increase the selenium content of crops, and
And yield and the quality of crops can be improved.Selenium can improve the immunity of humans and animals, prevents disease, but due to humans and animals
The internal organ that there is not Long-term Storage selenium, the selenium needed for body should constantly be supplemented from food.Chinese Soclety of Nutrition
Recommend selenium daily intaking amount be 50-200 μ g, and China adult every day selenium intake only 26-32 μ g, do not reach far away recommendation
Daily intaking amount.China lacks selenium population and reaches more than 100,000,000, domestic many endemicity diseases occurred frequently, as Keshan disease, Kaschin-Beck disease, cancer,
Cardiovascular and cerebrovascular disease, diabetes, infertility, immunity of organisms go down and aging course etc. more than 40 is planted diseases and all taken the photograph with selenium in meals

Foliage-spray, because of soil fixing and a large amount of drift, not only selenium effectiveness is low, and safety and less economical, therefore can not become
The selenium supplement measure that agricultural product produce.Nanometer selenium, biological selenium are to solve a kind of effectively selenium additive, the mesh of inorganic selenium safety issue
Front method is mainly by the reduction inorganic selenium such as vitamin C, phenylhydrazine, and biological selenium is then by process of crop growth mistake, logical
Cross sprinkling inorganic selenium, make Crop and bioconversion occur and obtains, and adding nanometer selenium or the biological selenium of commercialization to fertilizer
It material is the main source of selenium in current selenium-enriched fertilizer.Owing to commercially available nanometer selenium preparation process and storage process require height, biological
The acquisition of selenium needs process longer, and price is higher, causes the cost of fertilizer to raise.
Semen vignae sinensis (formal name used at school Vigna unguiculata), is commonly called as angle bean, Jiang Dou, band bean, hangs fresh kidney beans.Semen vignae sinensis is raw containing abundant dimension
Element B, C and phytoprotein, can make people's brains quiet, has conditioning digestive system, eliminates effect of chest and diaphragm distension.Semen vignae sinensis also may be used
Preventing and treating acute gastroenteritis, vomiting and diarrhoea, spleen invigorating of quenching one's thirst, the kidney invigorating stopping leak and supplementing QI for promoting the production of body fluid etc..
