通过对广东梅州本地种植的楠木(Phoebe zhennan S.Lee)进行种子采集,实施播种育苗,开展苗期生长节律观测实验,对苗期高生长进行了定株定期测量。结果表明:楠木1年生苗平均苗高39.72cm,平均地径4.83mm,生长期为4—11月,5—10月为苗木速生期,此时应加强肥水管理。同时分析结果表明气象因子对苗期高生长有密切相关性。
Seed collection was carried out on Phoebe zhennan S. Lee natively planted in Meizhou, Guangdong. Sowing and seedling cultivation was carried out to observe the growth rhythm at seedling stage, and the regular growth of seedlings was measured regularly. The results showed that the average height of one-year-old seedlings was 39.72 cm, the average diameter was 4.83 mm, the growth period was from April to November, and the period from May to October was the rapid growth of seedlings. Fertilizer and water management should be strengthened at this time. At the same time, the results showed that the meteorological factors are closely related to the high growth of seedling.
