摘要:对从昆士兰引进的5个大叶相思种源及1个本地种源,在琼海试点和花都试点进行试验,结果表明,引进种源在前者的生长表现均比后者好。不同种源在同一试验点比较,以15697和15483种源生长快、产量高,年平均生长琼海试点和花都试点分别为胸径2.0cm和1.3cm、树高2.3m和1.3m、生物量25.36t/hm2和13.63t/hm2以上,明显地优于其余各种源。花都试点的5个引进种源树高、胸径生长量及生物产量均比本地种源高。此外,在引进种源的林分中单干或直干型的单株,以15697和15483种源的林分居多,平均占40.4%~70.4%和45%~70%。由此看出。
This paper deals with a provenance trial of Acacia auriculiformis . Five provenances from Queensland and a local provenance were used in establishing two test plantations in 1988 in Qionghai of Hainan Province and Huadu City of Guangdong Province. Assessment results to the 6 year old trial plantations show that: ① all the five introduced provenances have a better growth performance in Qionghai site than those in Huadu; ② Among the tested provenances, provenances 15697 and 15483 have annual increments of, respectively in Qionghai and Huadu, 2.0 cm and 1.3 cm in diameter at breast height, 2.3 m and 1.3 m in tree height, and 25.36 t/hm 2 and 13.63 t/hm 2 in biomass production, that are higher significantly than the other provenances; ③ In Huadu, all the five introduced provenances grow much faster than the local one; ④ In the plots of introduced provenances 15697 and 15483, 40%~70% of individual trees have good stem form (single and straight stem). Based on the research results, provenances 15697 and 15483 have been determined as promising provenance for afforestation.
