上海城市绿化月季品种的应用现状

在夏末秋初的月季（Rosa chinensis Jacq.）盛花期，对上海市内15处具有代表性的栽种月季的公园，以及道路上18个月季品种的生长情况进行了调研.归纳分析得出：上海地区更适宜栽种如“仙境”“安吉拉”等耐湿热品种，并且其种植量和范围已经形成规模，但是珍贵品种的推广情况有待提高；其次，土壤的养分以及病害对月季的长势影响较大，而大多月季绿化带生境情况并不理想，土壤肥沃率低下，黑斑病等病害在夏末时节的植株间传播率很高.本研究期望能为之后进一步加强适生彩化、珍贵化月季品种筛选、培育、配置研究等关键技术研究提供数据参考.

Current application status of urban greenery Rosa chinensis varieties in Shanghai, China

In this paper, we conducted a study of the growth of 18 varieties of roses (Rosa chinensis Jacq.) in 15 representative parks and roads in late summer and early autumn, when the roses are in full bloom. The results showed that it is better suited for Shanghai to plant heat and humidity tolerant varieties such as "Wonderland" and "Angela", and that they are already planted on large scale both in quantity and in area. However, the promotion of cherished varieties needs to be improved. Secondly, soil nutrients and diseases have a significant impact on the growth of roses, and most of the habitats in the green belts are unsatisfied, with low soil fertility and high rates of disease spread between plants in this season, such as black spot. We hope that the present study will provide a data background for further strengthening of key technical studies such as screening, breeding and configuration studies of suitable colourful and precious rose varieties in the future.
