摘要:
对黄土丘陵区不同立地中柳枝稷生长响应的变化规律进行了研究。结果表明：柳枝稷在不同立地条件下土壤水分明显不同，坡地土壤平均含水量（13.39%）<梯田（14.78%）<川地（16.02%）。土壤水分含量，根系生物量和土层深度三者存在密切相关性。在梯田、坡地和川地三种立地条件下，柳枝稷的株高、覆盖度、生物量、杂草和枯落物等均存在明显差异，其中柳枝稷的株高和覆盖度表现为川地>坡地>梯田；伴生杂草和柳枝稷枯落物与地上部生物量表现一致，川地显著高于坡地和梯田。地下生物量在川地、坡地和梯田立地下均呈现相同规律，随深度变化根系量逐渐减少，三种立地条件下总地下生物量差异不明显。同时发现土壤有机质和N含量与柳枝稷生产力呈显著正相关，说明了黄土丘陵区柳枝稷的生长响应与立地水肥条件有关。这对加强优良禾本科牧草的生态适应性研究及促进我国黄土高原生态可持续发展以及退耕还草工程具有重要的现实意义。
Abstract:
The law of growth response of Panicum virgatum L.in different locations of the Loess Plateau was conducted.The soil water content showed a significant increase named as sloping field (13.39%)P.virgatum.A close relationship was discovered in soil moisture, root biomass and soil depth.In the above sites mentioned the plant height, cover rate, the biomass, weed and the plant debris of Panicum virgatum L.exhibited a distinct response to the location characteristic, among which the height and coverage declined orderly with the plain to sloping field to terrace.However, as well as surrounding weed biomass and the debris, the above-ground biomass of P.virgatum in the plain acquired a greater amount compared that in terrace and sloping field.In addition, the content of organic matter and nitrogen element in the grown soil showed a closely positive relationship with the productivity establishment of P.virgatum.Therefore P.virgatum could grow well in different habitats in the loess hilly regions because of its wide adaptability.Therefore the variation of water content and fertilizer in soil determined the growth response of P.virgatum on hilly regions of the Loess Plateau.
