通过对江汉平原引种栽培的落羽杉人工林进行试验调查和树干解析,研究探讨了落羽杉树高、胸径和材积的生长规律,结果表明:落羽杉树高前期生长较快,之后逐渐减慢;胸径连年生长量和平均生长量均表现为先升后降,其中10~15 a生长最为迅速;材积生长在9 a前较慢,连年生长量在21 a达到最大,在28 a左右达到数量成熟龄,笔者对江汉平原落羽杉试验林的生长规律进行了研究,以期为落羽杉的引种栽培,造林规划和科学经营提供基础数据和理论数据。

The growth regulation of height,DBH and volume was studied and discussed by the trial investigation and stem analysis of Taxodium distichum(L.)Rich plantation in introduction and cultivation in Jianghan Plain,the results showed that Taxodium distichum(L.)Rich had a rapidly height growth in the early stage and then the speed slowed down gradually;annual increment and mean increment of DBH had the same growth regulation with a growth rate raised and then fell,it had the highest rapid between tenth to fifth year;The volume grew slowly during the first ninth year and then the annual growth with a rapidly rate,the twenty-first year Taxodium distichum(L.)Rich had the largest current annual volume increment.It can be estimated that the Taxodium distichum(L.)Rich would be mature around the twenty-eighth year.Growth regulation of Taxodium distichum(L.)Rich experimental forest in Jianghan Plain provided basal and theoretical data of introduction and cultivation,afforestation planning,scientific management.
