建立火炬松、湿地松无性系种子园,需要大量的优树接穗。由于目前我省成年的母树很少,优树数量极为有限,同时每株优树又不能提供很多的接穗,这给建立种子园带来极大困难。为了探讨解决优树接穗供不应求和在生长期嫁接、提高成活率的途径,我们今年进行了生长季节火炬松的针叶束带皮贴接试验。 自五月下旬开始,到九月份为止隔半个月──20天接一次,每次接50株左右。砧木用二
The establishment of loblolly pine, Pinus elliottii seed orchard, need a lot of tree scion. Due to the fact that there are only a few mature trees in our province at present, the number of superior trees is extremely limited. At the same time, each superior tree can not provide many scions, which brings great difficulties to the establishment of the seed orchard. In order to explore ways to solve the shortage of scion tree and grafting in the growth period and improve the survival rate, this year we carried out the coniferous belt affixed test of the growing season. From late May to September, half a month - once every 20 days, take about 50 plants at a time. Rootstock with two
