摘　　要：通过堆积腐解处理生长在Cu污染土壤上的修复植物-海州香薷,将其研制成堆肥,作为基肥施用于缺Cu土壤,以矫正作物缺Cu症状。盆栽试验研究了这种堆肥对冬小麦(TriticumaestivumL.)生长和Cu吸收的影响。结果表明,施用海州香薷堆肥可显著提高生长在缺Cu土壤上的小麦的株高、生物量和籽实千粒重。与CK相比,千粒重可提高58.9%,籽实产量提高近1倍;而在这种缺Cu土壤上单纯施加N、P、K化肥,反而降低小麦生物量和籽实千粒重。可见,将Cu污染土壤上生长的修复植物海州香薷制成堆肥,施用于缺Cu土壤是一种可实现修复植物资源化的有效途径。A pot experiment was conducted to examine the effect of compost from Elsholtzia splendens on growth and Cu uptake of winter wheat （Triticum aestivum L.） grown in a Cu-deficient soil. Results showed that application of the compost significantly increased plant height, biomass and 1000-grain weight. The compost increased 1000-grain weight by 58.9% and grain yield by one fold compared to those of the control. Simply amendment of chemical fertilizer to the Cu deficient soil decreased wheat 1000-grain weight and grain biomass. The results indicated that composting Elsholtzia splendens grown in a Cu-contaminated soil and then applying the compost to a Cu -deficient soil is a feasible and effective way.
