不同季节几种观赏树种扦插繁殖试验研究

The Experimental Studies on Cuttage and Propogation of Some Landscape Trees in Different Seasons

针对北京地区6种园林观赏树种:沙地柏、大叶黄杨、金叶女贞、珍珠梅、金银木、红瑞木分别在3月、5月、7月、11月四个时期进行扦插繁殖试验,初步确定出这6种观赏树种的最佳扦插繁殖时间及可适用扦插繁殖的时段,为这6种观赏树种在不同季节扦插繁殖提供了理论依据。研究表明,沙地柏、大叶黄杨、金叶女贞、珍珠梅、红瑞木在一年四季都能进行扦插繁殖,金银木的最佳繁殖季节是春秋两季。

This article is mainly about the experimental studies on cuttage and propogation of six landscape trees: Sabina vulgaris, Euonymus japanicus, Lgustrum.ovalifolium var. aureo-marginatum × vulagare, Sorbaria kirilowi, Lonicera maackii, Cornus alba during the periods of March, May, July and November. It is preliminarily made certain the best time and period of cuttage and propogaion of the six trees. It provides theory basis about different seasonable cuttage and propogation of the six trees. According to the studies, it is proven that Sabina vulgaris, Euonymus japanicus, Lgustrum.ovalifolium var. aureo-marginatum × vulagare, Sorbaria kirilowi, Cornus alba can be cutted and propogated in the four seasons of a year, the best propagation period of Lonicera maackii is spring and autumn.
