Method for cultivating functional crops using nano organic germanium and nano organic selenium

A method for cultivating functional crops using nano organic germanium and nano organic selenium, the method comprising:

• performing irrigation or foliar fertilization on plants of the crops with nanoscaled organic germanium and nanoscaled organic selenium, which are prepared in nanoscale sizes by performing one or two or more selected from a method of applying physical energy selected from the group consisting of heat and pressure to organic germanium and organic selenium, a method of applying electrical explosive energy, and a chemical bonding process, at least twice at the time when the plants of the crops are most vigorously grown and developed and at the time of maturation to bear fruit, wherein the prepared nanoscaled organic germanium and nanoscaled organic selenium are onecomponent materials which are dispersed in water as a solvent in a nanoscale state,
• wherein the organic selenium is composed of a selenium compound, and the selenium compound is obtained by dissociating one or two or more raw materials selected from the group of consisting of selenium oxychloride (SeOCl2), selenium sulfide (SeS2), selenium tetrachloride (SeCl4), selono-L-cystine (C6H12N2O4Se2), seleno-L-methionine (CH3SeCH2CH2CH(NH2)CO2H), selenophene (C4H4Se), selenous acid (H2SeO3), and germanium selenide (GeSe, GeSe2), and reducing ions to extract selenium.
