坡向与造林密度对刨花润楠幼林生长的影响

在福建省华安葛山国有林场,通过对不同坡向和2种造林密度的10年生刨花润楠林分生长量调查分析,结果表明:不同坡向对刨花润楠树高和胸径生长有显著影响,以东北坡的刨花润楠生长量最大,胸径达到8.1 cm,树高9.1 m;其次为西坡、北坡、南坡;东坡最小。种植密度对刨花润楠生长有显著影响,适当的提高造林密度能够促进刨花润楠的生长。

Study on the Effect of Aspect and Afforestation Density on Machilus Paunoi Kanenira Young Forest Growth

Investigation and Analysis on the growth condition of the ten years old Machilus Paunoi Kanenira with different planting aspects and 2 densities were made on Fujian Hua'an Geshan National Forest Farm,the results showed that: the different aspects significantly effected tree height and DBH,the DBH was 8.1cm and the tree height was 9.1m on northeast slope,the other was on the order of west slope,north slope,south slope and east slope.Planting density significantly effected the growth of the Machilus Paunoi Kanenira,increasing planting density appropriately might promote the growth of the Machilus Paunoi Kanenira.
