摘要

以大豆、棉花、曼陀罗、蓖麻和玉米为供试材料

采用土柱栽培试验

探讨Cd胁迫后

5种植物根系活力与各器官间Cd含量的差异

以及5种植物根际土壤酶活性与根际土壤营养含量对Cd胁迫的反应。结果表明:(1)5种受污染的植物体Cd富集量超出对照不受污染的植物体达3～7倍之多

但都未达富集临界值100mg/kg。(2)不同植物不同器官Cd运转积累部位不同

以根冠比衡量

蓖麻、玉米、棉花R/S大于1

称作根优势植物;大豆、曼陀罗R/S小于1

称作冠优势植物;棉花R/S近于1

称作冠根均衡植物。5种植物吸收富集最强的前3位植物(大豆、玉米、棉花)都是人工驯化的栽培植物

其吸肥能力强于野生植物的

这种吸肥能力与吸Cd能力是否呈正相关关系

吸肥能力的差异是否可以作为污染土壤利用改良的依据值得进一步研究。(3)大豆、曼陀罗茎秆中Cd含量均较根、叶、籽实中的高

考虑到大豆是粮食作物

同时其根部Cd含量仅次于茎的

而曼陀罗作为一种杂草

其地上部Cd转移系数大于1.0

因此

比较供试5种植物

应优先选择曼陀罗用于Cd污染区域的土壤净化。(4)Cd胁迫(5mg/kg)提高了5种植物根系还原TTC强度

抑制了大豆和蓖麻根际土壤多种酶活性

而...

Abstract

Phytoremediahon is a promising new method that is used green planted to take up or deloxify Cd from contaminated soils.With soybean(Glycine max)

cotton(Gossypium hirsutum)

dutura(Dature stramonium Datura)

castor oil plant(Ricinus communis) and maize(Zea mays) as materials

soil column culture experiment was used to study differences of root activities

Cd accumulation in organs

rizhospheritic soil enzymes activities and soil nutrition contents of five plants under Cd(5 mg/kg) stress.The results indicated:(1)U...
