| 摘要: |
| 对广东省肇庆市属7个国有林场2007—2010年种植的500.60 hm2降香黄檀进行调查分析，并作了适生性评价。结果表明，降香黄檀在大水口林场和大南山林场的适应性最好，在大坑山林场和清桂林场次之，在北岭山林场局部地区生长表现良好，但在新岗林场和葵垌林场生长不适应。降香黄檀幼龄林仅能耐持续5 d以内的霜冻，短于3 d的霜冻无冻伤，4～5 d的霜冻有轻微冻伤；10～15 d会出现较重冻伤；45～60 d出现严重冻伤甚至全株冻死；种植2 a以上的植株在地上部分冻死后能重新萌芽生长，而种植1 a的植株在地上部分冻死后未见萌生新芽。适生性的评价结果可为肇庆市属国有林场及邻近地区发展降香黄檀提供参考依据。 |

| Abstract: |
| A total of 500.60 hm2 of Dalbergia odorifera were planted in seven state forest farms of Zhaoqing from 2007 to 2010. Growth situation and adaptability of D.odorifera were investigated and evaluated. The plantations displayed the best growth in Dashuikou Forestry Farm and Dananshan Forestry Farm, intermediate adatability in Dakengshan Forestry Farm, Qinggui Forestry Farm, and partial area of Beilingshan Forestry Farm, and the worst performance in Xinggan Forestry Farm and Kuidong Forestry Farm. The young plantations of D. odorifera tolerated a short period of frost less than 5 days. No injury was observed at the sites with frost period less than 3 d, but slight damage in 4 to 5 d frost; More severe damage from frost appeared at the sites in 10 to 15 d frost and trees died in the condition with 45 to 60 d frost. Two year old saplings sprouted after suffering frost damage, while one yearold seedlings died immediately after frost damage. These results provided useful information for the development of D. odorifera lantation in Zhaoqing and surrounding areas with similar climate. |
