摘要: 为探讨微量元素在土壤中的安全范围,采用温室盆栽的方法,研究土壤中锌和硼的有效含量对烟草生长及其他元素积累的影响。结果表明,当土壤有效锌含量达到4.69 mg/kg或有效硼含量达到3.32 mg/kg时,烟株都会表现出中毒症状;土壤有效锌含量较高时,锌向叶片积累,有效硼较高时,硼向茎中积累;硼与铁、镁相互促进,与钙拮抗,锌与铜相互促进,与铁表现出相互抑制。

Abstract: To investigate the safety of trace elements in soils, the greenhouse pot method was be used to study the soil effective content of zinc and boron on tobacco growing and other elements accumulation. The results showed that when the soil available zinc content reach 4.69 mg / kg or effective boron content reach 3.32 mg / kg, the tobacco plants might exhibit symptoms of poisoning; when soil zinc content is high, more zinc alloted to the leaves, and when the soil boron content is high, more boron distributed to the stem; boron could promote the accumulation of ferrum and magnesium, and inhibit the accumulation of calcium, zinc could promote the accumulation of copper, and inhibit the accumulation of ferrum.
