摘　　要：银白槭具有很高的观赏价值,值得在国内推广应用。对美国进口的干燥种子和鲜活种子进行播种育苗试验,并对银白槭的出苗率、当年生长量与育苗技术进行研究。试验结果表明,苗床直播与穴盘点播,鲜活种子具有萌芽早、出苗快、出苗率高的特点。穴盘点播的鲜活种子的出苗率为84.0%,发芽持续时间为13d。银白槭春播种子当年平均高生长量为121.30cm,夏播种子当年平均高生长量为80.5cm。银白槭生长季需加强水肥管理,促其健壮生长,及时喷施农药预防天牛及红蜘蛛等。幼苗冬季最好假植以保护越冬。Acer saccharinum is worth applying in China,because of its good ornamental value.Seeds sowing and seedling-raising tests were completed by using dry and fresh seeds of A.saccharinum imported from the USA.The germination rate,plant height productivity in the current year and the seedling-raising technique were studied.The results showed that compared with the dry seeds,the fresh seeds sprout earlier,emerge faster and with a higher seedling emergence rate in both the seedbeds and cell trays.Germination rate of fresh seeds were 84.0% and duration of germination is 13 days.The average height productivity in the current year of A.saccharinum which sowed in the spring is 121.30 cm,while the average height productivity in the current year of A.saccharinum which sowed in the summer is 80.5 cm.In order to promote the plants growth robust,seedlings of A.saccharinum should be treated with good water and fertilizer management in the growing season.Moreover timely spraying of pesticides is needed to prevent wood-boring pests of longhorn beetle and spider which is harmful for leaves.Seedlings in winter need to be temporary planted.
