摘要
安溪半林林场在杉木迹地上营造福建柏,并选留杉木萌芽条形成福建柏杉木混交林,不论混交林经营密度大小,福建柏生长均比纯林好。大、中密度组的福建柏生长比萌芽杉木快,但在小密度组则相反。萌芽杉木在大、中密度条件下,生长不如同龄纯林,在小密度条件下的平均树高、胸径是纯林的140.2%和148.2%。说明福建柏与萌芽杉木混交培育方式是成功的,但到15年生以后,经营密度以1 500株.hm-2左右,混交比例6∶4为宜。
Fokienia hodginsii were planted on the cutting-blank land of Cunninghamia lanceolata, and the sprouted Cunningharnia lanceolata was selected to create the mixed plantation. No matter what the mixed forest density is, the mixed forest of Fokienia hodginsii were better than the pure ones, the high and middle density＇s Fokienia hodginsii grew faster than that of sprouted Cunningharnia lanceolata, but the low density is opposite. The mixed sprouted Cunningharnia lanceolata did not grow as faster as the pure ones at the same age. The average height and diameter were 1. 402 and 1. 482 times than the pure ones in low density condition. It showed that the cultivation mode of Cunninghamia lanceolata and Fokienia hoclginsii mixed plantation was successful, however, the effect density should be control in 1 500 individuals· hm^-2, and the proportion should be controlled at 6： 4.
