采用土培和液培试验研究了不同小白菜品种植株吸锌量的差异及原因。结果表明 ,不同小白菜品种从土壤介质中累积吸锌能力差异显著 ,这种差异是由于品种间根系形态特征的不同造成的。在低锌条件下 ,小白菜植株吸锌量与根系参数呈显著正相关。
Soil culture and liquid culture experiments were used to study the differences and reasons of zinc absorption in different Chinese cabbage cultivars. The results showed that there was significant difference in zinc accumulation ability of different Chinese cabbage cultivars from soil media, which was caused by the different morphological characteristics of roots. In the low zinc conditions, cabbage plants zinc absorption and root parameters were significantly positively correlated.
