The mineral elements were analyzed by the Principal Component Analysis and the Factor Analysis on the SPSS 10.0 and three main factors were picked. The results showed that Se, S and Se-S cooperated application enhanced the garlic nutrition quality by increasing mineral nutrition. The garlic Vc was the highest after using higher Se compared middle S level （S 20 mg/kg soil ＋ Se 40 mg/kg soil）. Lower Se level compared middle S level （S 40 mg/kg soil ＋ Se 20 mg/kg soil） get the highest garlic abio-Se in all treatments. The garlic organic Se content was the highest after using higher Se compared middle S （S 40 mg/kg soil ＋ Se 40 mg/kg soil）. The treatment lower S compared lower Se level get the highest garlic allicin in all treatment. It showed that the fresh eating factor was affected by the element Se. The flavor factor and health care factor were affected by both Se and S.展开更多

Therefore, it is necessary to guarantee the stable quality of raw materials with pre-assigned qualitative factors. It is possible to solve these problems by separating raw materials by grades, including the rejection of the portions of material unsuitable for specific application, and by reasonable control of the processing parameters based on real-time infirmation about chemical composition of raw materials. This can be effectively achieved by MAYA laser ele- mental analyzers based on LIBS. Being applied in ex traction, beneficiation and processing of the mineral raw materials, LIBS analyzers can be used for automatic sor ting ＂ the ore extracted or crushed and automatic dosage of components to stabilize the composition of raw material mixtures.展开更多
