3个闽楠种源幼苗造林试验研究

Experimental Study on Afforestation of Three Seedlings of Phoebe bournei

该研究在不同坡位进行了3个闽楠种源幼苗的造林试验,并调查其造林成活率和生长状况。结果表明:尤溪种源的闽楠幼苗造林成活率最高,地径生长量和株高生长量均显著高于沙县种源和政和种源;不同坡位的造林成活率和生长指标均表现为下坡位>中坡位>上坡位,下坡位造林有利于闽楠幼苗的生长。

The afforestation experiments of three seedlings of Phoebe bournei were carried out at different slope positions, and the survival rate and growth status were investigated. The results showed that the survival rate of Youxi provenances seedling was the highest, and the growth of ground diameter and plant height were significantly higher than those of Shaxian and Zhenghe. The survival rate and growth index were all in the descending slope〉 mid - slope position〉 up - slope position. Downhill afforestation was beneficial to the growth of Phoebe bournei.
