摘要
在福建省永安国有林场以广东仙菊种子园的湿地松和福建省漳平五一国有林场种子园的马尾松为对照，开展了闽中低山丘陵火炬松家系引种试验，结果表明：不同火炬松家系适应性和抗逆性在不同的年龄段存在差异。不同家系在速生性、适应性存在差异但不显著。经8a连续观察、综合评判，筛选出速生性、适应性好的CT-1、TX-4家系，在Ⅱ类立地和一般经营管理水平条件下，8年生时树高、胸径、材积分别为6．71～6．83m、11．96～12．03cm、0．0384～0．0396m^3．分别比马尾松提高6．5％～8．4％、3．9％～4．5％、13．6％～17．2％，比湿地松提高14．3％～16．4％、15．9％～16．1％、53．0％～57．8％，可作为短周期工业原料林树种进一步引种栽培与推广示范。
Taking slash pine in a Grangdong seed orchard and masson pine in Fujian Zhangping Wuyi National Forest Farm as the controls in Fujian Yong＇ an National Forest Farm, the introduction experiment of Pinus taeda family on low massif in middle of Fujian was developed, the results showed adaptability and adversity resistance of different Pinus taeda families were different in different age periods, fast-growing and adaptability of different families were different instead of significantly different, through 8- year-long continuum observation, and synthesis judge, CT-1,TX-4 families with good fast-growing and adaptability were screened out, on the conditions of Ⅱ type of site and common management level, height, dbh, and volume of 8-year-old tree were 6.71 6.83m, 11.96--12.03cm, and0.0384--0.0396m^3, 6.5%--8.4%,3.9%--4.5%,and 13.6%-17.2% higher than those of masson pine, 14.3% --16,4%, 15.9% --16.1%, and 53.0% --57.8% higher than those of slash pine, it might be further introduced and cultured, and popularized and demonstrated as short-cycle industrial raw material forest.
