摘要
本试验的姜田土壤经测定有效锌含量为０．６５ｐｐｍ，有效硼含量为０．３２ｐｐｍ。单纯施锌（硫酸锌）增产２４．０％，同时施锌和硼（硼砂）增产３８．９％。施锌后提高了生姜植株各器官的锌浓度；累积吸锌量也有大幅度提高；植株的锌主要在生育后期吸收；施锌还增加生育后期锌在根状茎中的分配。施硼主要提高了生姜叶片中的硼浓度；累积吸硼量也有大幅度提高；施硼还增加了硼在叶片中的分配比例。
The available Zn and B in the experimental ginger field were 0.65 and 0.32 ppm,respectively. Application of Zn at 30 kg hm￣2 increased the yield by 24.0%, and addingZn+B (30+15 kg hm2) increased the yield by 38.9%. Application of Zn increased the concentration of this element in different organs, greatly enriching Zn in the whole plant. The largst amount of Zn was absorbed at the latter growth stage, with were more portion distributed into rhizoma at this stage. Application of B mainly enriched B in leaf blades.
