苦木 PicraSma Puassioides(D Don)是我省优良速生珍贵用林树种之一。为满足生产发展的需要,宜春地区官山天然林保护区、宜丰县石花尖垦殖场珍贵树种研究所、官山林场林科所于一九七六年开始,研究苦木的凡殖技术。经试验,苦木用嫁接和扦插都能凡殖。在高温干旱季节,扦插成活率以可达60%以上;切接或髓心形成层对接,成活率也在40%以上。嫁接比扦插的植株长势要好。
Bitter wood PicraSma Puassioides (D Don) is one of the fine fast growing precious tree species in our province. In order to meet the needs of production development, Guanshan Natural Forest Reserve in Yichun Prefecture, Precious Species Research Institute of Shifengcun Habitat Rehabilitation Farm in Yifeng County and Guanshan Forestry Center Linke Research Institute began to study the cultivation technology of bitter wood in 1976. After the test, bitter wood with grafting and cutting all who can reproduce. In the hot and dry season, the survival rate of cuttings can reach more than 60%; butt joint or pith formation layer, the survival rate is above 40%. Grafting better than cutting the growth of plants.
