    Rotation and manure amendment increase soil macro-aggregates and associated carbon and nitrogen stocks in flue-cured tobacco production

    ZOU Congming; LI Yan; HUANG Wei; HU Xiaodong; ZHAO Gaokun; YANG Xuebiao; CAI Yonghao; JIN Yan
    Yunnan Academy of Tobacco Agricultural Sciences of CNTC, Kunming City, Yunnan Province, P.R. China
    Flue-cured tobacco production in China is typically over-fertilized and mono-cropped. To understand how this agronomic management affects soil structure and organic matter, this study investigated the effect of rotation, fertilizer rate and manure ...

    Study on absorption and transport of potassium (K) by foliar application in tobacco leaves

    DENG Xiaopeng; GAO Shudi; CHEN Yahua
    Yunnan Academy of Tobacco Agricultural Sciences of CNTC, Kunming City, Yunnan Province, P.R. China
    Effects of the foliar fertilizer on the uptake of potassium (K), as well as translocation and distribution among different position of tobacco leaf were studied under lack of K conditions. In order to study the suitable contents and the critical value of ...

    Determination of maleic hydrazide and its two glucosides in tobacco leaves using hydrophilic interaction liquid chromatography tandem mass spectrometry

    LI Yong; PANG Tao; SHI Junli; KONG Guanghui; LU Xiuping; JIN Yan
    Yunnan Academy of Tobacco Agricultural Sciences of CNTC, Kunming City, Yunnan Province, P.R. China
    A hydrophilic interaction liquid chromatography tandem mass spectrometry-based method for the simultaneous determination of maleic hydrazide (MH) and its two glucosides in tobacco leaves was developed. The method was based on the synthesis of MH-O-ß-D ...
