Abstract:
PURPOSE: A plant growth control method using LED light and an antioxidant enzyme growing strategy are provided to increase production by controlling the growth of agricultural products. CONSTITUTION: A plant growth control method using LED light comprises the following steps: controlling plant growth by selecting LED light of blue light, green light, or red light. If the LED light is red or green light, length growth of the plants is promoted. The structure of the plant is secured if the LED light is the blue light. An antioxidant enzyme growing strategy for plants using LED light increases an antioxidant enzyme of the plants by irradiating plants with blue short wavelength LED light. The blue light has the wavelength band of 460 nanometers.
Abstract:
PURPOSE: A natural biomass silica nanopowder with an excellent contaminant removal ability extracted from a cornstalk pellet and a manufacturing method thereof are provided to selectively manufacture an amorphous silica, which is a highly graded silica, by controlling pH, and a mineral silica can be replaced as a corn stalk is recycled as a biomass resource. CONSTITUTION: A manufacturing method of a natural biomass silica nanopowder with an excellent contaminant removal ability extracted from a cornstalk pellet comprises steps of: pre-processing a cornstalk pellet ash to remove minerals other than silica, extracting the silica by controlling pH to be 6 to 11 in an aqueous solution including the pre-processed silicon, and obtaining a silica nanopowder by centrifuging and drying the extracted silica.

Abstract:
PURPOSE: Bacillus subtilis L32 and Saccharomyces cerevisiae L13 isolated from soil are provided to lower salinity in soil, to prevent plant pathogen, to reduce stress and disease in crops, and to enhance crop yield. CONSTITUTION: Bacillus subtilis L32 prevents plant pathogen. Saccharomyces cerevisiae L13 is inoculated to soil and changes insoluble phosphate into soluble phosphate. Bacillus subtilis L32 and Saccharomyces cerevisiae L13 are cultured in a solid medium contains 5 g/L of a yeast extract, 2 g/L of a malt extract, 10 g/L of peptone, 10 g/L of dextrose, 2 g/L of sodium chloride, and 15 g/L of agar in 1000 ml of distilled water.
Abstract:
PURPOSE: A controlling method of a phytopathogen is provided to restrain growth of phytopathogen by blue light-irradiating plants. CONSTITUTION: A controlling method of a phytopathogen comprises a step of irradiating a plant with blue light. The blue light is irradiated from an LED source. The blue light has a wavelength of 400nm - 550 nm. The wavelength of the blue light is 460 nm. The phytopathogen is gray mold phytopathogen.
