| 摘 要： | 在对美洲黑杨大树调查中新发现一种丛生型生长方式,表明丛生具有极高生长量,每公顷材积可达1055.85 m3。文章对丛生古,树的应用价值(经济性、抗逆性)和学术价值进行了评价,认为如果解决种苗问题丛生造林是一种很有发展前途的丰产栽培方式;此外,还探讨了丛生成因和另一丰产类型--"三出头"。

| Abstract: | A caespitose growth pattern was found in the survey of big-diameter Populusd eltoides. The authors made an investigation on their growth， and the results indicated that the caespitose growth pattern has an extremely high growth volume， and the wood output reaches 1055. 85m3 per hectare. This paper evaluated its application value ( economy and resistance) and academic value and argued that caespitose growth afforestation is a high yield silviculture mode and have a promising future if the seedling problem can be resolved. This paper also discussed the causes of caespitose growth and then introduced a high yield mode --“three branches”. |
