摘要/Abstract

摘要： 研究了沙埋对科尔沁沙地6种优势植物的种子萌发和幼苗出土的影响.进行0、2、4、6、8、10和12cm等7个深度沙埋处理.结果表明,在不同沙埋处理时,沙蓬萌发差异显著,而差不嘎蒿2cm埋深与其他埋深的发芽差异显著,其他种植物0cm埋深与其他埋深的发芽差异显著;沙埋对所有植物幼苗出土均有显著影响,埋深增加,出苗率减小;繁殖体大的物种与繁殖体小的物种相比,能从更深沙层中出苗,幼苗出土最大深度排序为苦参>东北木蓼≥沙蓬>山竹子>雾冰藜>差不嘎蒿.

Abstract: This paper studied the effects of sand-burying on the seed germination and seedling emergence of six dominance plants in Keerqin Sandy Land.Six treatments of artificially sand-burying to depths 0,2,4,6,8,10 and 12 cm were designed.The results showed that the seed germination of Agriophyllum squarrosum was significantly different(P<0.05)between different treatments,but that of Artemesia halodendron was only significantly different(P<0.05)between 2 cm and other burial depths.For other four plants,their seed germination was significantly different(P<0.05)only between 0 cm and other burial depths.Sand-burying significantly affected the seedling emergence of all plant species.The emergence rate decreased with increasing burial depth.Higher emergence percentages were obtained at 2 and 4 cm burial depths.The species with larger seeds emerged from deeper depth,and the maximum burial depth of seedling emergence was Sophora flavescdens>Atraphaxis manshurica≥Agriophyllum squarrosum>Hedysarum fruticosum>Bassia dasyphylla>Artemesia halodendron.
