Abstract:
PURPOSE: A biodegradable plant propagation multi-pot is provided to have moderate strength for plant propagation, and to improve sterilization ability, deodorant ability and heterogeneity, and to be naturally degradable in soil. CONSTITUTION: An environment-friendly composition for plant propagation comprises 30-60 weight% of rice chaff, 5-15 weight% of rice bran, 5-15 weight% of starch, 5-10 weight% of urea, 1-10 weight% of titanium powder, and 20-30 weight% of water. A manufacturing method thereof comprises: a step of crushing the rice chaff and the rice bran by using a pulverizer; a step of forming a composition for plant propagation by using the crushed rice chaff and the rice bran; a step of mixing the composition for plant propagation for 10-20 minutes; and a step of molding the composition by heating and pressurizing.
Abstract:
PURPOSE: A non-destructive analysis method is provided to effectively analyze ingredient consisting of fatty acid of a grain. CONSTITUTION: A non-destructive analysis method for a fatty acid composition of a single granule comprises: a step of randomly selecting a plurality of prediction model development group and prediction model evaluation group; a step of measuring near infrared absorption spectrum of two groups; a step of randomly selecting grain granule sample among the prediction model development groups and measuring near infrared ray absorption spectrum; a step of pulverizing the granule sample and performing chemical analysis of fatty acid ingredients; and a step of applying primary and secondary derivatives to the absorption spectrum.
Abstract:
A method for evaluating sheath blight resistance is provided to obtain an objective evaluation result conveniently regarding the sheath blight resistance, raise the inoculation efficiency of pathogenic bacteria of the sheath blight and improve the resistance evaluation method, thereby contributing to breed a species with resistance to the sheath blight. A method for evaluating sheath blight resistance comprises the steps of: (a) after inoculating a liquid culture mycelia of Rhizoctonia solani into rice, sealing the inoculation portion tightly using a shielding film such as aluminum foil for maintaining moisture required for vitality of the mycelia; and (b) after cultivating the mycelia inoculated rice until disease is progressed into branches and leaves, evaluating the resistance degree, wherein the resistance degree evaluation is performed by evaluating the attack degree of all leaves sheaths corresponding to the inoculated stem with 0 to 9 steps and calculating a virus infection rate of the inoculated stem in accordance with a following calculating formula of the virus infection rate being equal to (9n9+7n7+5n5+3n3+1n1+0n0)/9N Î 100(wherein each of the n0 to n9 is a number of leaves sheaths corresponding to each of the attack degree evaluated at the mycelia inoculated stem, and the N is the total leaves sheaths of the mycelia inoculated stem).
Abstract:
색상및 열안정성이향상된수수천연색소의제조방법, 수수천연색소추출물에아세트알데하이드를처리하는단계를포함하는천연색소의안정화방법및 상기천연색소를플라스틱성형재료에혼합하여플라스틱성형물을제조하는단계를포함하는천연색소로착색된플라스틱성형물의제조방법에관한것이다. 수수로부터천연색소추출물을추출한후, 이를아세트알데하이드와축합반응하여색상및 열안정성이향상된고분자화된천연색소를제조하였으며, 이를플라스틱과혼합하여, 색상안정성이향상된플라스틱을제조할수 있다. 따라서, 이러한방법에의해생산된플라스틱을이용하여천연색소를함유한인체친화적이고위생적인제품을개발할수 있다.
