Effects of Molybdenum and Manganese on Nitrate Reductase Activity and Quality of Brassica campestris ssp. chinensis 钼锰对不结球白菜硝酸还原酶活性及主要营养品质的影响
Mn/ CeO_2 was prepared by impregnating CeO_2 aerogel with the solution of manganese nitrate. The prepared aerogels were characterized by TEM, BET, CO oxidation reaction and H_2-TPR. 以硝酸锰浸渍制得的氧化铈气凝胶Mn/CeO2,用TEM、BET、一氧化碳催化氧化活性评价和H2TPR对所制备的催化剂进行了研究。
The results show that spraying molybdenum fertilizer and manganese fertilizer can decrease nitrate contents in Chinese cabbage significantly. Molybdenum fertilizer and manganese fertilizer also increase nitrate reductase activity. 结果表明:喷施钼肥和锰肥降低蔬菜硝酸盐含量效果最佳,也显著增强了硝酸盐还原酶的活性。
Effects of Foliar Spraying Molybdenum, Manganese on Growth and Nitrate Content of Lettuce 叶面喷施钼锰对莴笋生长发育和硝酸盐含量的影响
However, the results also reveal that the application of phosphorus, potassium, molybdenum, manganese and zinc will effectively decrease the nitrate content. 施用磷钾肥及钼、锰、锌等微量元素肥料能够有效地降低蔬菜体内硝酸盐含量。
ICP-AES determination of arsenic 、 bismuth 、 iron 、 manganese 、 lead 、 stibium in pure copper by coprecipitation with lanthanum nitrate 硝酸镧共沉淀ICP-AES法测定纯铜中砷、铋、铁、锰、铅、锑
Nano-LiMn_2O_4 spinel oxides has been prepared successfully by roasting precursor in the air atmosphere, while precursor was obtained by sol-gel techniques, with lithium nitrate and manganese nitrate as original material and citric acid as complexant. 以硝酸锂、硝酸锰为原料,柠檬酸作为络合剂,采用溶胶凝胶法获得前驱体,然后将前驱体在空气气氛中焙烧制备了纳米LiMn2O4。
Sulotion of manganese chloride or manganese nitrate, as a commonly used medium in electromagnetic liquid separation, often contaminates and dissolves the minerals separated to some extent. 电磁液体分离法的常用介质氯化锰、硝酸锰溶液,对矿物有一定的污染和溶解作用。
