对乌兰布和沙漠优良固沙先锋树种花棒(H edysarum scop arium)的克隆生长构型进行了研究。结果表明,花棒具有独特的克隆生长构型,由枝条遇沙埋形成长间隔物的典型的游击型克隆生长构型和由根条形成的典型的密集型克隆生长构型。且固定沙丘的花棒分株种群比半固定沙丘具有较大的密度、较小的平均株距及相似的分株高度。
The clonal growth patterns of Hedysarum scop arium, an excellent sand fixation pioneer in the Ulan Buh Desert, were studied. The results showed that the flower buds had a unique clonal growth pattern, a typical guerrilla clone growth pattern formed by long branches of sand shoots and a typical dense clonal growth pattern formed by root strips. And the fixed sand dune Hibiscus ramets population than the semi-fixed dunes have a greater density, smaller average plant spacing and similar ramet height.
