摘　　要：永安国有林场1994年营造米老排杉木混交林,经过1个轮伐期试验,结果表明:米老排能够适应永安市气候表现早期速生特性;在-5.6℃极端低温和40℃极端高温天气能恢复正常生长;6年生平均树高8.35m、胸径8.46cm;12年生平均树高10.20m、胸径10.81cm;28年生6米老排4杉木混交林保存密度1941株/hm^(2),单位面积蓄积340.23m^(3)/hm^(2);米老排树干通直圆满,可作为永安市及其周边中亚热带地区松林改造、杉木混交造林树种。A mixed plantation of M.laosensis with Cunnighamia lanceolata was built at 1994 on Yongan national forest farm.After 1 rotation,the results showed that M.laosensis had adapted to the climate in Yongan city and grown rapidly in early stage,and recovered to normal growth rate after enduring to extreme temperature,such as-5.6℃or 40℃.The average height at 6-year-old was 8.35m and DBH was 8.46cm.The average height at 12-year-old was 10.20m and DBH was 10.81cm.The preservation density of mixed forest with 6 M.laosensis 4 C.lanceolata at 28-year-old was 1,941 plants/hm^(2),and the unit area accumulation was 340.23m^(3)/hm^(2).With straight and perfect tree trunk,M.laosensis can be used as pine forest reconstruction and C.lanceolata mixed afforestation tree species in the middle subtropical area of Yong’an city and its surroundings.
