本文主要阐述了杠柳的生物学特性、训化培育繁殖以及在高速公路绿化应用的跟踪观察。发现此种植物具有非常强的根分蘖特性。通过对杠柳的扦插、移植等研究,解决了其扦插繁殖技术,可以在短期内获得大量苗木,其栽植成活率高,造价与传统护坡品种紫穗槐持平。同时初步观察牲畜不啃食,绿期长,观赏效果好,护坡防护作用明显。在普遍存在高速公路绿化因放牧造成很大破坏的形势下,推广使用杠柳护坡具有很大的现实意义。
This paper mainly expounds the biological characteristics of Periploca aureole, training for breeding and propagating, as well as tracking the application of highway greening. This plant was found to have very strong root tillering characteristics. Through the research on the cutting and transplanting of the barbadosus, the cuttage propagation technology has been solved and a large number of seedlings can be obtained in a short time. The planting seedling has high survival rate and the cost is the same as that of the traditional slope cultivar Amorpha fruticosa. At the same time preliminary observation of livestock does not eat, green long, good ornamental effect, protective effect of slope protection is obvious. Under the situation that the greening of the highway is greatly damaged by the grazing, it is of great practical significance to promote the use of the boulder slope protection.
