生物柴油植物“油莎豆”的发展前景

Development potentials of chufa for biodiesel production

油莎豆(Cyperus esculentus l.var.sativus beock)是一种草本植物,其块茎含油量较高(质量分数为10%～36%),可加工成生物柴油。油莎豆生长周期短,抗逆性强,耐贫瘠,病害少,栽培管理容易,可大力推广种植。通过现代生物技术可进一步改良其生物学性状(尤其是含油量),以开发其作为优质生物质能的潜力。作为块茎含油的草本植物,油莎豆具有其它油料作物或木本油料植物不可比拟的优越性,在生物柴油的发展领域具有十分广阔的应用前景。

Chufa （or yellow nut-sedge, Cyperus esculentus L. var. sativus Beock） is an herbaceous 151ant. With higher oil-bearing content （10%-36%） in the tuber, it may be processed for biodiesel production. Moreover, broad tolerances to environmental factors, less diseases or pests, and easily-managed plantation, could ensure its development in a large area. Through modern biotechnology approaches, chufa would be promoted in many biological and economic features （especially increasing its oil-bearing content） in order to improve its potentials on biodiesel production. It is believed that chufa, as herbaceous and tuber oil-bearing plant, possesses greater advantages in the field of biodiesel development by comparison with other oil-bearing crops or trees.
