摘　　要：对昆明地区元宝枫种子进行不同催芽方法和播种期筛选试验,种子处理有沙藏催芽、浸种催芽和直播育苗(对照)3种,播种时期从3月中旬至5月上旬共6个处理,分别对齐苗天数、出苗率、苗高和地径进行观测记录。结果表明:昆明地区元宝枫种子经浸种催芽后播种效果最好,并以4月上旬播种为宜。An experiment was conducted with seeds of Acer truncatum to select the right sowing time and methods for seed treatment in Kunming area. The experimented seed treatment measures included sand stratification, water soaking and direct sowing as control. The sowing time tested included six options from mid of March to early May. The average emergence days, emergence rate, seedling height and basal diameter were observed and recorded as evaluation criteria in the experiment. The results showed that water soaking was the best seed treatment before sowing, and the best sowing time was mid April.
