| 摘 要： | 采用桶栽试验,研究了镉铅单一及复合胁迫对玉米干物质及玉米镉铅吸收的影响。结果表明,玉米穗质量、穗粒质量、生物产量与土壤镉铅含量呈显著负相关;镉铅在玉米体内的分配规律为:根>茎叶>穗轴>籽粒;在相同质量浓度镉胁迫下,镉铅复合胁迫处理的玉米各部位对镉的吸收大于镉单一胁迫处理,同质量浓度铅胁迫下,铅镉复合胁迫处理的玉米茎叶对铅的吸收小于铅单一处理。

| Abstract: | The pot cultivation experiment was adopted to study the effects of single and compound pollution of Cd and Pb on the dry matter and the uptake of Cd and Pb of maize.The results showed that the ear weight,grain weight and biological yield of maize had negative relationships with the soil rate of lead and cadmium.The cadmium and lead distribution in maize plant was:root>leaf>cob>kernel.For the same treatment dosage,the cadmium uptake rate of maize under the compound pollution of cadmium and lead was higher than in single cadmium pollution treatment,but the lead amount in maize stalk under the compound pollution of cadmium and lead was lower than in single lead pollution condition. |
