| 摘 要： | 从立地指数、经营管理水平和造林密度3方面入手,系统地研究了山东省的黑杨(Populus nigra)不同栽培模式的生产力和适宜培育目标．以工艺成熟为前提,兼顾数量成熟,利用经济成熟作为确定黑杨大径材人工林定向培育的合理采伐年龄．结果表明:在立地指数18以上的立地上皆适宜培育大径材,合理的造林密度为250．0～333．3株／hm2,合理采伐年龄为10～12 a．同时,提出了6种可显著提高黑杨大径级工业用材定向培育经济效益的优化栽培模式． |

| Abstract: | Based on the different site indices ,management level and planting density, different cultivation patterns of poplar plantation(Populus nigra)have been summarized and their productivity and suitable end products were analyzed. Along with the consideration of technical mature age and quantitative mature age,the economic mature age,which was determined by the maximum of NPV (net present value), was used to determine the optimal rotation age for large-grade timber production. The results showed that the suitable planting density was 250. 0-333. 3 tree/hm2and the optimal rotation age was 10-12 a on the forest land with 18 SI (site index) or more. 6 optimum cultivation patterns,which could bring more economic returns,were selected from the various cultivation patterns. |
| Keywords: | Populus nigra large-grade timber directional cultivation cutting economic mature |
