查询词典 evergreen tree

The study shows that: evergreen broad-leaved species during the middle and later period succession have better adaptability under the different light surroundings, such as Elaeocarpus glabripetalus, Ilex integra, Photinia prunifolia, Cinnamommum camphora. And Fluorescent Characteristics also verifies the above result. The experiment results indicate that: PSⅡreaction centers of majority tree species are not marked oxidized under the full light surroundings. Photosynthetic electron transport activity can maintain highly, in this way, it is helpful to enhance radiant energy dissipation and thus dissipate excess light energy. That is to say, the increase of non-photochemical quenching coefficient can conduce to protect PSⅡ, and mitigate the effect of high light on photosynthesis.

研究发现处于演替中后期的常绿阔叶树种幼苗，对光环境的变化均有着较强的适应能力，秃瓣杜英、全缘冬青、小叶铁冬青、桃叶石楠、香樟等树种的表现尤为突出；荧光特性的研究也应证了这一观点，测定结果表明多数树种的PSⅡ反应中心并未受到明显氧化破坏，在全光照条件下仍能维持较高的光合电子传递活性，能通过提高非辐射性热耗散，消耗PSⅡ吸收的过剩的光能，从而保护PSⅡ反应中心免受因吸收过多光能而引起的光氧化伤害。

In order to develop "water saving garden" and provide a theoretical basis to the green of arid areas. The experiment was conducted with 5 species tree seedlings of evergreen broad-leaved Prunus zippeliana, Lithocarpus glaber, Cinnamomum camphora, Schima superba, and Photinia glabra×P.

为了发展节水型园林及为干旱地区绿化提供理论依据，采用盆栽控水的方法，研究了不同干旱胁迫对大叶桂樱Prunus zippeliana，石栎Lithocarpus glaber，樟树Cinnamomum camphora，木荷Schima superba和红叶石楠红罗宾Photinia glabra×P。

The results were as follows: 1 There were 7 133 trees, belonging to 23 species and 18 genera and 13 families, and their average DBH, crown and height were respectively 27.59 cm, 4.10 m and 6.94 m. In general their average crown was relative small. 2 S, H (Shannon-Wiener index), and D of biodiversity index were small, and there were the obvious difference in those indexes among different streets, which suggested that there were certain monotone of the tree species and structure layer. 3 The dominant species mainly consisted of evergreen trees that were Ficus virens var. sublanveolata, Ficus benjamina, Roystonea regia, Terminalia hainanensis, T.

结果表明：1梅州城区行道树共有13科18属23种7133株，其平均胸径、平均冠幅、平均树高分别为27.59cm，4.10m，6.94m，总体上看，平均冠幅偏小；2物种丰富度指数S、Shannon-Wiener指数H和Simpson指数D偏小且各道路间差异明显，说明各道路行道树存在一定程度的物种单一性、层次的单调性；3梅州市城区行道树优势树种是大叶榕、垂榕、大王椰子，次优势种为海南榄仁、阿珍榄仁、阴香，它们是梅州城市街道绿化的好树种。
