摘要：

多枝柽柳(Tamarix ramosissima)是塔里木河下游荒漠河岸林中的优势灌木,对荒漠河岸植被群落的稳定起着重要作用。该文通过研究多枝柽柳幼苗根系形态对不同灌溉处理的响应,分析人工水分干扰对多枝柽柳幼苗根系生长的影响。实验设计了侧渗分层和地表灌溉两种给水方式和高灌(50L·株–1)、中灌(25L·株–1)、低灌(12.5L·株–1)三个给水水平,并在整个生长季节监测每个植株的生物量及根系形态参数。结果显示:与地表灌溉比较,侧渗分层的灌溉方式显著提高了细根(0.5mm 更多还原 AbstractFilter('ChDivSummary', 'ChDivSummaryMore', 'ChDivSummaryReset');
