为大力发展油橄榄,开辟新的木本油沅,我所从1974年以来,采用女贞作砧木,油橄榄做接穗进行了嫁接试验,已初步获得成功,接活率达86%。1976年12月检查1975的嫁接苗,平均树高125厘米,平均干粗1.8厘米,其中最大树高达172厘米,粗2.3厘米。根据几年来的实践证明,女贞嫁接油橄榄是有发展前途的。(1)女贞是我国南方乡土树种,资沅丰富,生活力较强,育苗容易,为大力发展油橄榄提供了有利条件。(2)嫁接苗能形成自生根系,有利提高成活率并能达到当年嫁接,当年出圃的要求。
In order to vigorously develop the olives and open up a new woody oil Yuan, since 1974, we have adopted the privet as the rootstock and the olive as the scion for the grafting experiment. It has achieved initial success, with the survival rate reaching 86%. In 1976 December inspection grafted 1975, the average height of 125 cm, average dry thickness of 1.8 cm, of which the largest tree up to 172 cm, 2.3 cm thick. According to years of practice has proved that privet grafted olive is promising. (1) Privet is a native tree species in southern China, rich in resources, strong vitality, nursery easy, to provide favorable conditions for the development of olive. (2) The grafted seedlings can form the self-rooting system, which can improve the survival rate and achieve the grafting of the year.
