一、前言在芬兰,关于沙棘栽培的研究为数极少。大多数沙棘品种所进行的初步试验,通常采用播种的方法。但用这种方法,不能一代代保持其品种的优良特性。当然,无论是在大面积的防护林带里,还是在曾遭受浸蚀威胁的植物栽植区,用种子繁殖也是无可非议的。而硬枝扦插繁殖无疑是一种好的方法。硬枝插穗,晚秋从母株上剪下,要贮藏在冷藏室或在渠沟里用雪复盖,曾作为植物繁殖 I. Preface In Finland, there are only a few studies on seabuckthorn cultivation. The initial tests carried out on most seabuckthorn varieties are usually sown. But in this way, the good characteristics of their breeds can not be maintained for generations to come. Of course, it is beyond reproach to breed seeds, both in large shelterbelts and in areas where plantations have been threatened with erosion. The hardwood cutting propagation is undoubtedly a good way. Hardwood cuttings, cut off from the mother plant in late autumn, to be stored in the freezer or in the ditch covered with snow, had as a plant breeding
