以30个红麻和黄麻品种为材料,在不同改良处理(对照,100%矿渣+少量磷肥;改良一,90%矿渣 +10%泥炭土+少量磷肥;改良二,80%矿渣+20%泥炭土+少量磷肥)下进行室外盆栽试验,测定了植物存活情况、生物量和植物各部位Pb、Zn含量及其积累总量,并根据植物Pb、Zn积累总量对30种红麻和黄麻进行聚类分析。结果表明:(1)30个品种中有25个品种可成活。(2)在对照处理下,25个红麻和黄麻品种的地上部、地下部生物量平均值为3.453 g和1.243 g;而在改良一处理下,其地上部、地下部生物量平均值为5.702 g和2.297 g;改良二处理下,地上部、地下部生物量平均值为9.271 g和3.210 g。(3)红麻和黄麻品种对Pb、Zn都具有一定的吸...

In this study, 30 cultivars of kenaf or jute were used as materials and the pot experiment was carried out at different modifier concentrations (control: 100% lead-zinc slag + small amount of phosphate fertilizer; Improved group 1: 90% lead-zinc slag + 10% peat soil + small amount of phosphate fertilizer; Improved group 2: 80% lead-zinc slag + 20% peat soil + small amount of phosphate fertilizer). The plant survival, biomass, Pb and Zn contents in different parts of plant and their accumulation were determined. Based on the accumulation of Pb and Zn in plants, 30 cultivars of kenaf or jute wer...
