于2013年期间采用株行距10 cm×10 cm、10 cm×15 cm、15 cm×20 cm等3种密度进行了乌桕播种育苗生长效果比较试验，结果表明：乌桕一年生播种苗的最适密度为株行距10 cm×15 cm，生长量最高，平均苗高达137.7 cm，平均地径达1.81 cm，平均主根长度达60.5 cm，≥5 cm长Ⅰ级侧根平均条数达26.3条。%Comparative test of growth effect of sowing seedling of Sapium sebiferum with 3 density designs,such as 10 cmí10 cm,10 cmí15 cm,15 cmí20 cm,was carried out in 2013. Results showed that the optimal density for the one-year Sapium sebiferum was 10 cmí15 cm,growth was the highest,the average height was 137.7 cm,the average diameter was 1.81 cm,the average root length reached 60.5 cm,≥5 cm Ⅰ-level lateral root average number was 26.3.
