| 摘 要： | 随着污水灌溉面积的持续扩大,研究污水灌溉带来的重金属污染问题,特别是重金属污染物对土壤-作物系统的影响显得尤为重要。通过试验,研究了重金属铅对玉米生长发育和对玉米性状及产量的影响。研究表明,随着土壤铅污染浓度的升高,单株叶面积、株高、总干物重等形态指标呈降低的趋势,平均单株穗长、穗粗、穗重、总粒数、百粒重下降,秃尖长度增加,玉米产量呈下降趋势。当土壤铅浓度为300 mg/kg时,玉米亩产下降21%左右。

| Abstract: | With the development of wastewater irrigation,it is very important to study the influence of heavy metal pollution,espetially the influence of heavy metal pollution on soil-crop systems.Through experiments,the influence of heavy metal plumbum(pb.)on corn growth,output and quality are studied.It is shown that with the increase of soil pb.content,the index,such as unit leaf area,the height,the weight,etc.has shown a decreasing trend.The average corn spike length,spike diameter,unit spike weight,total grains/p... |
