摘要
指出了杉木香樟采用混交、纯林不同模式整地造林,苗木种植之后成活率较高。幼林经过4 a的经营管理,结果显示:试验地Ⅰ每公顷的苗木成活率,幼林4 a生的林木每株平均树高、地径、树冠、单株材积、每公顷蓄积,分别比试验地Ⅱ、Ⅲ每公顷成活率分别提高3.7%~11.0%。幼树生长株树分别保存率提高1.0%~12.8%,幼林4a生生长的林木每株平均树高提高5.8%~8.9%,地径粗15.7%~17.47%,树冠大7.4%~3.6%,单株材积大42.9%~33.3%,每公顷蓄积多46.36%~54.13%。可见杉木香樟不同方式整地造林经营模式,4a生混交林林木的生长量,均比杉木香樟纯林林木的生长量有所高,可以推广。
The mixed and pure forests of Cinnamomum camphora were used to prepare land for afforestation.After afforestation,the young forests were managed for 4 years.The results showed that the average tree height,diameter,crown,volume per plant and volume per hectare of the four-year-old trees in experimental site I increased by 3.7%~11.0%compared with experimental sitesⅡandⅢrespectively.The preservation rate of young trees increased by 1.0%~12.8%respectively;the average tree height increased by 5.8%~8.9%;the ground diameter increased by 10.76%~17.47%;the crown increased by 7.4%~3.6%;the individual volume increased by 42.9%~33.3%and the volume per hectare increased by 46.The results showed that the growth of mixed forest with 4 years was higher than that of pure forest of Cinnamomum camphora in different land preparation and afforestation management modes.
