香根草种植年限对煤矸石山基质理化性质的影响
|
摘要
【目的】研究不同种植年限香根草(Vetiveria zizanioides)对煤矸石山基质理化性质的影响.【方法】选取种植香根草3、4、6、9、14 a的煤矸石山作为研究对象,探讨香根草不同修复年限下煤矸石地0～50 cm土层基质理化性质的变化.【结果】随着香根草种植年限的增加,煤矸石基质容重、孔隙度、含水量得到显著改善.各土层基质有机质、碱解氮、速效磷、速效钾均呈现增加的趋势.在0～50 cm土层,种植香根草14 a煤矸石山基质有机质、碱解氮、速效磷、速效钾分别比种植3 a香根草煤矸石山基质增加9%、43%、26%、55%,且0～10 cm土层各理化指标均随种植年限增加而提高.【结论】种植香根草有助于改善煤矸石山基质的理化性质,改善效果随种植年限的延长而越来越明显.
【Object】 To explore the mending effects of Vetiveria zizanioides growing different years on physiochemical properties of soil based on coal gangue.【Method】 V.zizanioides was planted in coal gangue based soil for 3,4,6,9 and 14 years and the soil samples within 0～50 cm layer were collected to evaluate the change of physiochemical properties.【Result】 The porosity,contents of water,organic matter,alkaline hydrolysis nitrogen,available P and available K increased along with the increase of planting years,while the bulk density declined.The contents of organic matter,alkaline hydrolysis nitrogen,available P and available K were increased by 9%,43%,26% and 55% respectively in 14-year compared with those in 3-year.The improving effect of V.zizanioides growing on physiochemical properties of coal gangue based soil in 0 to 10 cm layer increased along with the planting years.【Conclusion】 V.zizanioides growing could improve the physiochemical properties of coal gangue based soil and the effect increased along with the planting years.
