摘要:
以土壤和风化砂混合物作为栽培基质,设计5种土壤铅含量梯度处理(对照、100、500、1 000、2 000 mg/kg),研究了土壤铅胁迫下4种北方阔叶树种(茶条槭、山梨、五角槭和山荆子)1年生盆栽苗的生长反应和抗性。结果表明:低含量铅(含量<500 mg/kg)刺激了多数树种的苗高、地径、叶片和新枝的生长,随着铅含量的继续增加植物生长量下降;土壤中铅抑制了多数树种的根系生长,根系各指标的变化树种间差异明显。采用隶属函数综合分析得出,4个树种对土壤铅污染的抗性大小顺序为山梨、茶条槭、山荆子、五角槭。2 000 mg/kg铅处理下,植物体对铅的富集能力大小依次为根、茎、叶。4种供试苗木中,山梨对土壤铅的富集能力最强。
Abstract:
In this paper,the gradient of soil Pb concentration (CK,100,500,1 000,2 000 mg/kg) was established by mixing Pb(CH3COOH)2 with soil and sand. The growth responses and resistance of four northern broadleaved tree species Acer ginnala,Pyrus ussuriensis,A. mono and Malus baccata to soil lead contamination were studied by growing their seedlings in pots in greenhouse.The results indicated that the seedling growth of all test species was enhanced under lower Pb concentrations (<500 mg/kg),including seedling height, ground diameter,leaf blade and the amount of new branches. With the increasing of Pb concentration, the growth became declined.Soil lead prevented the root system’s growth of most species.The changes of every index and difference between species were obvious. According to comprehensive analysis of above indices by using membership function,we could arrive at a conclusion that the P. ussuriensis had the strongest resistance of soil lead contamination,and next was A. ginnala, M. baccata, A. mono. Under the highest Pb concentration(2 000 mg/kg) the root of plant had the strongest enrichment of Pb,and the following was stem,leaf blade. P. ussuriensis had the stronger enrichment of soil lead than other three species.
