北京与广州城市公园花境植物应用调查研究 总被引:3,自引:3,他引:0
《广东园林》2019,(5)
植物材料是花境景观效果的基础,花境植物种类多样、色彩丰富、配置灵活,南北城市的花境植物不同,直接影响了其在城市园林植物配置与景观效果。以北京、广州两地各5个效果良好的花境为实例,对比与分析两地花境营造的植物选择、配置与造景效果等,结果表明:调研的北京公园花境植物应用了63种,隶属36科59属,其中常用的有49种;广州公园花境植物应用了71种,隶属40科62属,常用53种;两地共有种16种,隶属14科16属;北京公园花境素雅而富有野趣,广州公园花境精致而色彩斑斓。 相似文献

广州素有"花城"之称,花境植物在广州城市公园的应用广泛,具有良好的观赏价值和生态价值.文章对广州市6个城市公园的花境植物应用及其配置模式进行调研分析.结果显示,广州公园常用花境植物95种,隶属61科88属;常用的4种配置模式分别是观叶灌木+观叶草本+观花草本、观花灌木+观叶灌木+观叶草本、观花灌木+观叶灌木+观叶草本+观花草本、观叶灌木+观叶草本;运用乡土植物或热带亚热带植物进行花境配置,能体现岭南特色及亚热带风情,然而花境应用中存在乡土植物较少,人工痕迹较为明显,自然野趣不足等问题. 相似文献

花境是一种极具美感的自然式植物配置形式,它起源于西方,在国外的应用历史悠久,但在我国的应用还不多。通过对长沙市典型的一些公园、居住区、道路和休闲广场等地的植物景观进行调查,发现长沙市的植物景观设计开始注重花境的运用,目前长沙市应用的花境形式主要有草坪花境、路缘花境、林缘花境、墙垣花境、滨水花境,花境植物种类共43科59种,其中应用较多的有22种。针对目前长沙市花境的应用不广泛、品种单调,植物种类少,设计手法不成熟等问题,提出政府管理部门应给予重视,大力开发乡土野生植物,适度引进新优品种,并提高花境设计师设计水平的建议。 相似文献

玫瑰花保藏方法与精油得率关系的研究 总被引:2,自引:0,他引:2
根据实际条件对玫瑰花的保藏方法进行了研究,寻找出了几种有效的保藏方法.包装袋A保藏玫瑰花,温度变化小,花香、花色好,是一种既经济又简便易行的短时间保藏玫瑰花的好方法,可保藏24 h;室内摊放,散热好、玫瑰花不发热,在放置6 h后因后熟作用,出油率比立即提取提高20%,但随着时间的延长,香气不断向空气中散失,出油率下降,所以室内摊放保藏鲜花时间不宜过长,最好不要超过6 h;冷冻能长时间地保藏玫瑰花,出油率亦不受影响;盐渍可以较长时间地保藏玫瑰花,15%的加盐量效果较好. 相似文献

目的:研究石榴花挥发油的化学成分及β-葡萄糖苷酶对其的增香作用。方法:使用挥发油提取器提取石榴花的挥发油,以GC-MS法进行分析鉴定,用面积归一化法获得各化合物的相对含量。结果:分别从无酶和有酶的石榴花挥发油提取物中确证了42个化合物。证明β-葡萄糖苷酶可以增加石榴花中某些香精成分的相对含量,但也使其中某些成分的相对含量减少。结论:石榴花中的化学成分十分丰富,GC-MS可以对石榴花挥发油进行良好的分离鉴定,同时证明β-葡萄糖苷酶对石榴花的增香作用不显著。 相似文献

To clarify key characteristics of the process whereby dormancy is released in male flowers of Cryptomeria japonica, twigs with male flowers were collected every three days between December 1992 and February 1993. Half of the twigs collected on each date were chilled at 0°C for three days and the cumulative temperatures required by the chilled and non-chilled flowers for florescence were compared. There was no difference in the cumulative temperature required for florescence between chilled and non-chilled male flowers collected before 19 December. However, for samples collected between 21 December and 21 January, the cumulative temperature needed for the florescence of chilled male flowers was 8–68°C lower than that required for non-chilled male flowers. However, there was little difference again in the cumulative temperature required to induce the florescence of chilled and non-chilled male flowers for collection dates later than 24 January. These results suggest that the dormancy of male C. japonica flowers was gradually released by exposure to low temperature and the process was completed by 24 January. The cumulative temperature required for florescence and the sum of the mean daily temperatures between the date of collection and the date of natural pollen dispersal were almost equal after the dormancy of the male flowers was released. The exact day on which pollen will be released can be predicted using the dormancy characteristics of male flowers. 相似文献

Beetle samples were compared between catches by traps and those on flowers in a Japanese beech (Fagus crenata Blume) forest, in Minakami, Gunma Prefecture, Japan. White plastic traps (Sankei Chemical Co., Ltd.) equipped with benzyl
acetate were set out for a month from July 23 to August 23, 1993, and all beetles captured were collected every six days.
During six days from August 10 to August 16, beetles were captured with traps and on wild flowers (Aruncus sylvester Kostel andAngelica polyclada Franch) at three hour intervals. Over the month, the traps captured 1,677 individuals of 73 species of 20 families, which
included 16 (89%) species captured on flowers in the six-day period. Over the six days, the traps captured 327 individuals
of 21 species of 12 families, compared with 685 individuals of 18 species of 5 families on the flowers; all of the families
and nine (50%) species of beetles taken on the flowers were also captured by the traps; all of the species with more than
five individuals captured on the flowers were also trapped. This suggests that capture by traps might sufficiently cover the
beetle fauna on flowers. The number of species and individuals, as well as their changing patterns, however, varied more irregularly
during the six-day period with the traps than with those on the flowers.
A part of this paper were presented at the 46th meeting of the Kanto Branch of the Japanese Forestry Society (1994)
