| 摘要: |
| 为了进一步弄清桂西北种植光皮桦(Betula luminfera)的生长量,于1997年4月在广西林朵林场营造光皮桦人工纯林,与马尾松纯林进行对比研究,结果表明:3.5年生光皮桦林分的平均树高、平均胸径和平均蓄积量分别为7.42 m、7.50 cm和30.06 m3·hm-2,分别比同龄马尾松林分的平均高(4.58m)、平均胸径(4.96cm)、平均蓄积(18.193m3/hm2)提高62.0%、51.2%和65.3%。说明该区营造光皮桦人工幼林的生长量较大,建议在相似立地条件下局部推广营造光皮桦人工林。 |

| Abstract: |
| To probe into growth of Betula luminfera plantation in the conditions of Northwest of Guangxi,the pure stands of B. luminfera were planted at Linduo Forest Farm in Tian'e County, northwest of Guangxi in April 1997.The pure stands of Pinus massoniana were also planted as control at the similar site conditions. The 3.5 years old stands of B. luminfera grew up to 7.42 m in high, 7.50 cm in diameter at breast high, and 30.06 m3 in volume on average, which are 62.0%, 51.2% and 65.3% higher respectively than the stands of P.massoniana. It is suggested that B. luminfera can be expanded to the area with the similar site conditions in this region. |
