【摘要】：欧李(Prunus humilis)是我国特有的野生果树资源。我国北方欧李资源丰富,其利用主要在野生欧李的驯化、选种、加工、杂交和繁殖等,将其作为一种观赏植物进行开发利用的研究还不多,利用欧李各器官观赏性进行较为系统的研究更少。本研究通过对欧李的主要观赏性状上进行调查评价、对欧李嫁接和整形修剪技术进行研究、对欧李的观赏应用模式进行探讨,以及从观赏角度分析欧李的综合效益,旨在总结归纳出欧李的观赏特性与应用价值,研究过程与结果如下:1.调查对象为河北科技师范学院园艺试验站欧李种质资源圃的欧李,于2014年3~11月观测记录欧李的物候期,调查欧李花朵、叶片和果实颜色、大小和形状。根据观赏指标的要求,对花朵、叶片、果实进行描述和评价,调查结果表明,欧李的花朵、叶片和果实均具有较高的观赏价值,观赏资源丰富多样,景观延续性好,并且选育出2个新品系‘W13-20’和‘W8-2’。2.为了提高欧李的观赏价值及观赏应用范围,研究了欧李的嫁接技术及整形修剪技术。结果表明,欧李嫁接可在每年的6月与9月进行,砧木以毛桃和毛樱桃亲和性较好。6月嫁接的方法为T形芽接,成活率为45.4%,成活后解开绑缚。9月嫁接的方法为嵌芽接,当年不解绑缚,次年萌芽前解缚剪砧,嫁接成活率为36.5%。欧李通过整形修剪可以提高其整体观赏性。3.根据欧李观赏性表现,提出了欧李的观赏用途以及配置原则和配置形式,欧李可以应用于公园、居住区、城市道路、高速公路、干旱地、沙荒地、旅游观光园、花境和插花等。4.从观赏角度分析了欧李带来的经济效益,社会效益和生态效益,结果表明将欧李推广应用于观赏领域其综合效益显著。
[Abstract]:Prunus humilis is a unique wild fruit tree resource in China. The northern part of China is rich in the resources of European plum, and its utilization is mainly in the domestication, selection, processing, hybridization and reproduction of wild prunes, but there are few studies on its exploitation and utilization as a kind of ornamental plant. Less systematic studies were carried out by using the ornamental properties of various organs of Euphorbia humilis. Based on the investigation and evaluation of the main ornamental characters of European plum, the grafting and pruning techniques of European plum were studied, and the ornamental application mode of European plum was discussed, and the comprehensive benefit of European plum was analyzed from the angle of ornamental. In order to sum up the ornamental characteristics and application value, the research process and results are as follows: 1. The phenological period of Euclio was observed and recorded from March to November of 2014 in the germplasm nursery of Euclio in the horticultural experiment station of Hebei normal University of Science and Technology. The color, size and shape of the flower, leaf and fruit were investigated. According to the requirements of ornamental indexes, the flowers, leaves and fruits were described and evaluated. The results showed that the flowers, leaves and fruits of Euchamnus oleifera had high ornamental value, rich and diverse ornamental resources, and good continuity of landscape. And two new lines were selected, I. e., W13-20 'and W8-2DX. 2. In order to improve the ornamental value and ornamental application, the grafting and pruning techniques were studied. The results showed that the grafting could be carried out in June and September of each year, and the rootstocks had better compatibility with Peach and Cherry. In June, the grafting method was T-shaped bud grafting, the survival rate was 45.4%, and the ligature was untied after survival, and the method of September grafting was embedded bud grafting. At that time, he was not bound, the following year before budding untying and cutting anvil, grafting survival rate was 36.5%. Eucalyptus can improve its overall ornamental. 3 by shaping and pruning. According to the ornamental performance of Oli, the ornamental use, the principle and the form of collocation are put forward. Oli can be used in parks, residential areas, urban roads, highways, arid areas, sandy wasteland, tourist parks, flower land and flower arrangement. In this paper, the economic, social and ecological benefits brought by Euclio are analyzed from the view of viewing. The results show that the comprehensive benefits of the application of Eucalyptus in the ornamental field are remarkable.
