造林地类型对闽楠幼林期生长的影响

Influence of different afforestation lands on the young growth of Phoebe bournei(Hemsl.) Yang

研究闽楠在不同类型造林地的生长规律,以为闽楠的林下套种提供技术支撑。在国外松近熟林下、杉木近熟林下和采伐迹地3种不同类型的造林地,以2年生闽楠轻基质容器苗进行造林试验。结果表明:国外松近熟林下与杉木近熟林下套种的闽楠造林成活率与保存率高于采伐迹地的;国外松近熟林下与杉木近熟林下有利于闽楠树高和地径生长,在国外松近熟林下种植的闽楠树高和地径生长量最大。

In order to find out the growth rules of Phoebe bournei （Hemsl.） Yang in different types of afforestation, the results of experiments could provide technical support for the interplanting of it. Using 2- years- old light base container seedlings of P- （Hemsl.） Yang were planted in three kinds of lands which were near-mature forest of Chinese fir,foreign pine and cutover land. The results showed that the survival rates and preserving rates of P. bournei （Hemsl.） Yangs of near-mature forest of Chinese fir and foreign pine were higher than cutover land＇s, and the two lands is benefit for the height and stem diameter growth of it. The largest growth of the height and stem diameter of it was in the near-mature forest of foreign pine.
