典型重金属污染农田能源植物示范种植研究

为探索安全经济利用重金属中度-重度污染农田的模式,在浙江某典型重金属复合污染农田开展了能源植物(甜高粱Sweet sorghum、甘蔗Saccharum sinensisRoxb.、香根草Vetiveria和盐肤木Rhus chinensis)种植示范研究.结果表明,经施加0.1%的石灰和0.2%的磷矿粉改良后,土壤p...

Field Demonstration ofEnergy Plants Production onHeavyM etalContam inated Farm land

To explore the possibility of safe and beneficial use of farmland moderately to heavily contaminated by heavy metals,a field demonstration of energy crop production was carried out on a heavy metal contaminated farmland in Zhejiang Province.The results showed the soil pH increased and available heavy metal contents significantly reduced after the addition of 0.1% lime and 0.2% phosphate rock.The biomass of sweet sorghum,sugar cane and vetiver was affected by available heavy metals in the soil.The total sugar and reductive sugar content of the juice from sweet sorghum and sugar cane were not significantly affected by the treatments.Sweet sorghum produced more than twice juice per unit area than sugar cane.The results showed that addition of soil amendments enabled energy crop production on farmland contaminated by heavy metals.
