Abstract: The seeds collected from a seed orchard of masson pine at Damangjie in Guangxi Tenxian grow rapidly with straight stem and strong adaptability, and the volume growth is 40.56%~100.00% greater than local common commercial trees. These trees were mainly propagated through seeding method. These seeds are suitable for germinating and growing in the environment like hills with attitude 300-800 m, low mountain, acid red soil which was developed from the sandstone and shale, granite, shale, gneiss and the purple sand shale, and the area with site index ≥16, slope less than 35°, deep soil and good drainage.

1976—1984年,在广西28个国营林场的人工林优良林分以及广西三大优良种源区的天然优良林分中选出优树601株,建立采穗圃,从601株优树中初选106个无性系作为建园材料,于1978—1982在广西藤县大芒界种子园建成初级无性系种子园。1987—1990年,在广西3个地区营建多年度种子园区域试验林,参试号分别为广西藤县大芒界马尾松(Pinus massoniana)初级无性系种子园种子混系和本地商品种。经过连续固定样地测定,该种子表现优于对照。1998,2004年分别在福建和重庆进行区域试验,当地商品种为对照。经过固定样地连续测定表明,该种子园混系生长迅速,干形通直圆满,适应性强。
良种特征特性生长迅速、干形通直、适应性强。在广西、福建和重庆3个区域试验点,该种子园混系的树高、胸径和材积分别比当地商品种增益10.20%~100.00%,14.30%~100.00%和40.56%~100.00%,其中材积增益较为显著,重庆点的增益尤为突出。
栽培技术要点及适宜栽培区域播种育苗:播种采用50 ℃温水浸泡3~5次,自然冷却法预处理,可缩短种子萌发时间并促进萌发,待种子50%以上露白后便可播种,种壳脱落前进行移栽,苗期注意遮荫保湿。7~10天进行喷药防病。适应海拔300~800 m的高丘、低山或低中山,由砂页岩、花岗岩、页岩、片麻岩、紫色砂页岩等母岩发育的酸性红壤,坡度小于35°,土层深厚、排水良好,立地指数≥16的地区种植。
