| 摘 要： | 通过叶面配合喷施不同浓度亚硒酸钠(Na2SeO3)和醋酸锌(CH3COO)2Zn·2H2O],研究硒(Se)、锌(Zn)及硒锌交互(Se-Zn)作用对春茶硒化学形态的影响。结果表明:(1)单独喷施Na2SeO3均能提高醇溶态、水溶态、盐溶态的硒含量,尤以200～400μg/mL的硒处理对春茶中硒的含量提高效应明显,其中醇溶态硒占总量的比例最大,水溶态次之,盐溶态最小,且醇溶态、水溶态硒占总量的比例分别较对照有不同程度的增加;(2)0.20%～0.40%的锌对3种化学形态硒含量有显著的提高效应,而高浓度锌(1.20%)抑制3种形态硒的吸收;(3)低浓度硒(50μg/mL)与不同浓度的锌配比,3种形态的硒含量整体都较低,醇溶态、水溶态硒所占比例差异不显著,但均显著大于盐溶态,其余浓度的硒锌配比,硒的化学形态分布与单硒相似,200～400μg/mL的硒与0.40%～0.80%的锌配合喷施,3种化学形态硒含量提高效应最明显,醇溶态、水溶态硒的比例分别较对照有不同程度的增加,又以200μg/mL的硒与0.80%的锌配比效果最好。 |

| Abstract: | Foliar spraying in different levels of Na2SeO3 and (CH3COO)2Zn·2H2O was carried out to determine the effects of Se, Zn and their interaction on the chemical form of Se in tea leaves in spring season. The results showed that: (1) The content of Se in alcohol soluble, water soluble, salt soluble was increased when spraying Na2SeO3, particularly the content of Se of three kinds of chemical forms was increased significantly when the spraying concentration of Se was 200～400 μg/mL. Among there the proportion of the total alcohol soluble, Se was the highest and water soluble was higher than salt soluble, the proportion of the total of alcohol soluble and water soluble Se increased in varying degrees comparing with the control. (2)The cumulative effect of the content of Se of three kinds of chemical forms was obvious when the spraying concentration of Zn was between 0.20%～0.40%. The Se of three kinds of chemical forms assimilation was restrained when the zinc concentration increased to 1.2%. (3)The overall three kinds of forms of selenium levels were lower and there was no obvious difference of the proportion of the total of Se between alcohol soluble and water soluble when spraying Se at 50μg/mL and the different concentration of Zn, but both of them were higher than salt soluble Se. The distribution of chemical forms of selenium was similar to single Se treatment when the spraying with the other concentrations of Se and Zn. The content of Se of three kinds of chemical forms was increased obviously when the spraying of Se in 200～400 μg/mL and Zn in 0.4%～0.8%, it also raised the proportion of the total of alcohol soluble and water soluble Se comparing with the control, but the effect achieved the best when spraying Se in 200 μg/mL and Zn in 0.80%. |
