我场从1988年开始进行马尾松、黄山松、湿地松、火炬松4种松树的扦插试验,1990年获得成功。1991年进行了重复试验,又获得新的突破,现已投入大田生产。1992年上述4种松树已扦插育苗达13万株,生长良好。根据1990和1991年2年的试验调查表明,这4种松树扦插生根率,扦插苗抽梢率、成苗率都达到85%以上。1年生马尾松、黄山松扦插苗平均高23.2cm,地径0.5cm,比实生苗分别高2.3cm和0.15cm;1年生湿地松、火炬松扦插苗平均高为25.9cm,地径2.4cm,比实生苗分别高2.4cm和0.1cm。另外,扦插苗比播种的实生
My field began in 1988, Masson pine, Pinus tabulaeformis, Pinus elliottii, loblolly pine cuttings of four kinds of experiments, in 1990 was successful. Repeated tests in 1991, but also to obtain new breakthroughs, has now been put into field production. In 1992 the above 4 kinds of pine cuttings have been raised 130,000 plants, grow well. According to the 1990 and 1991 two years of experimental investigation showed that the cutting rate of 4 kinds of pine cuttings, cuttings shoot rate, seedling rate reached more than 85%. Pinus massoniana and Pinus taiwanensis had the average height of 23.2cm and diameter of 0.5cm, respectively, 2.3cm and 0.15cm higher than that of the seedlings. The cuttings of Pinus elliottii and Pinus taeda on average were 25.9cm and 2.4cm in diameter, 2.4cm and 0.1cm higher than the seedlings respectively. In addition, cutting seedlings than sowing real
