| 摘 要： | 本研究以南美蟛蜞菊Wedelia trilobata为实验材料，选择煤矸石土进行栽培试验研究，选择普通有机土作对照，在栽培期间定期对南美蟛蜞菊的鲜重、生长速度、新芽数、新叶数、叶色等指标进行观察测定。实验结果表明：南美蟛蜞菊在煤矸石土生长40d时叶色深绿；新增茎节数与有机土植株之比为31：48，新叶数与有机土植株之比为96：182，生物量（鲜重）没有出现显著差异。说明南美蟛蜞菊在煤矸石土栽培有良好的生长适应性。适宜用于煤矸石土植被恢复和重建材料．

| Abstract: | Cultivation experiment of Wedelia trilobata was conducted in coal-gangue soil with common organic soil as control.During the cultivation the following characteristics of Wedelia trilobata were periodically measured or determined: fresh weigh,growth rate,number of new buds,number of new leaves and leaf color.Results: Wedelia trilobata grown 40d in coal-gangue soil had dark green leaves;the ratio of newly grown stem nodes on plants grown in coal-gangue soil to that of organic soil was 31:48;the ratio of new leaves between plants grown in the two kinds of soils was 96:182;and there was no significant difference in biomass(fresh weight) between plants grown in the two kinds of soils;these results indicated that Wedelia trilobata had a good growth adaptability in coal-gangue soil;therefore it was suitable to be used in coal mine wastelands for vegetation recovery. |
