我场现有马尾松、华山松、云南松、黑松、湿地松、火炬松等六种松。除马尾松外,其余五种松都是先后从外地引进的。两年来,我们对马尾松、华山松、湿地松、火炬松四个树种间的相互嫁接,作了尝试,其目的是: 1、初步了解这四种松之间的“嫁接亲合性”,以便进一步试验,为引种、建立无性系种子园、采穗圃扩大钻木材料的来源;并探求通过不同种间的嫁接促进嫁接母树开花结实、调节树形、矮化树冠、提高抗性的可能性。
My field existing masson pine, Pinus armandi, Pinus yunnanensis, Pinus thunbergii, Pinus elliottii, loblolly pine and other six kinds of pine. In addition to masson pine, the other five kinds of pine are imported from the field. In the past two years, we tried the mutual grafting of the four tree species of Pinus massoniana, Pinus armandii, Pinus elliottii and Pinus taeda. Its purposes are as follows: 1. To understand the “grafting affinity” among the four pine species, So as to further test and establish a clonal seed orchard for harvesting and expanding the source of the drilling material; and to explore the possibility of promoting the flowering and fruiting of the grafted parent tree, adjusting the tree shape, dwarfing the canopy and improving the resistance through the grafting of different species Sex.
