济南市木本园林植物资源调查与分析   总被引:3,自引:1,他引:2  
张鹤  周君 《中国农学通报》2015,31(22):148-151
为全面系统地掌握济南市木本园林植物的种类组成、生活型、季相特点以及应用现状,对济南市的木本园林植物进行全面、具体、系统、深入的调查。调查结果显示,济南市木本园林植物共计535种(包括变型、亚种和栽培变种),隶属于77科199属。其中裸子植物5科16属49种,被子植物72科183属486种(含双子叶植物69科174属467种,单子叶植物3科9属19种),济南市木本园林植物树种较为丰富。乔木植物286种,占所有种的53.4%;灌木植物216种,占所有种的40.4%;藤本植物33种,占所有种的6.2%,乔、灌类植物都比较丰富,藤本比较缺乏。所有树种中常绿树种103个,占所有种的19.25%;落叶树种432个,占所有种的80.75%;落叶树种占据优势。济南市的木本植物应用形式较为多样,但创新性应用不多。济南市木本园林植物应用方面存在的问题有:(1)济南园林树种数量较多,但优质利用的却不多;(2)济南市常绿树种应用较少;(3)乡土树种应用不够。建议:(1)科学搭配城市园林绿化树种;(2)推广栽植乡土树种;(3)积极引种驯化。调查结果为济南的木本植物资源可持续利用提供了可靠的科学理论依据。  相似文献

木本植物逆境胁迫研究进展   总被引:1,自引:0,他引:1  
木本植物(Woody plant)具有多年生、木质部发达和茎坚硬等特点,能抵御复杂多变的外界环境。本综述归纳了木本植物逆境胁迫的几个重要方面,例如盐胁迫、干旱胁迫和低温胁迫。归纳并总结了与应激有关的基因、蛋白质、转录因子和应激反应机制,并简要概述了木本植物在植被保护、园林绿化和土壤改良等方面的应用价值,最后对木本植物研究的局限性和存在的不足进行了讨论。蒙古柳(Salix linearistipularis)作为松嫩平原盐碱地区唯一具有群落分布的木本植物,是研究逆境胁迫的重要树种材料。因此,本综述着重介绍了耐盐碱木本植物蒙古柳对盐等逆境胁迫的研究进展,以期为木本植物逆境胁迫研究提供一定的理论基础;并针对目前研究存在的不足,为进一步研究提供了参考方向。  相似文献

Processing landscaping waste into biochar has been just initiated in China, biochar as a new soil improver has attracted wide concern home and abroad. This paper applied the pilot experiment method, and took Tulbaghia violacea and Malus micromalus cv. "American" as the test flower and tree to explore the impact of different biochar return-to-soil modes on plant growth. It was found that biocharcoveredsoil promoted the growth of both species efficiently, and relieved the poor growth, compared with the control group, biochar-covered-soil reduced yellow leaves, dead leaves and poor growth vigor of T.violacea by 47.8%, 20% and 100%, respectively, and it reduced poor growth, dead branch rate and root tiller germination of M. micromalus cv. "American" by 80%, 62.5% and 50%. The results showed that biocharcoveredsoil was better than biochar-mixing-soil.  相似文献

Design of plant landscape form is a critical part of plant landscaping, and it is an important direction of modern researches on urban plant landscaping to promote the development of plant landscape via the interaction between landscape form design and other means. By elaborating five major influence factors of landscape plants, namely "flexibility", "art", "subject", "mode", and "artistic conception", this paper explored the application of construction thinking in the construction of urban plant landscape form, in order to provide theoretical basis for the development of urban plant landscape form.  相似文献

To know the species composition, life form, seasonal features and application of woody landscape plants in Jinan City, woody landscape plants in the city were investigated comprehensively. The investigation shows that there are 535 woody landscape plant species in the city in total(including variants, subspecies and cultivars), belonging to 199 genera of 77 families. Among the 535 species, there are 49 gymnosperm species of 16 genera, 5 families, 486 angiosperm species of 183 genera, 72 families(including 467 dicotyledon species of 174 genera, 69 families, 19 monocotyledon species of 9 genera, 3 families). The fi gures refl ect rich woody landscape plants in Jinan City. There are 286 tree species, accounting for 53.4% of the total species; 216 shrub species, accounting for 40.4% of the total; 33 vine species, accounting for 6.2% of the total, thus tree and shrub species are diversifi ed, while vine species are limited. Among all tree species, there are 103 evergreen species, accounting for 19.25% of the total; 432 deciduous species, accounting for 80.75% of the total; so deciduous tree species occupy a prominent position. Woody plants in Jinan City are applied in diversifi ed forms, but seldom in innovative forms. Problems in the current application of woody landscape plants in the local area are summarized as(a) there are diversifi ed tree species, but only a few of them are applied in high effi ciency;(b) evergreen tree species are less used;(c) indigenous tree species are insuffi ciently used. Therefore, suggestions are given as(i) combine landscape plants scientifi cally;(ii) promote indigenous tree species;(iii) introduce and domestic new species actively. The investigation results provide scientifi c theoretical support for the sustainable utilization of woody plant resources in Jinan City.  相似文献

Abundant lands of China such as Suzhou, Hangzhou, Sichuan and Chongqing are all located in the basin of the Yangtze River, and subtropical evergreen broad-leaved forest belt, enjoy mild climate, sufficient rainfall, rich ornamental plant resources and diversifi ed landscaping techniques. In the long-term landscaping practices, plant furnishing arts characterized by diversifi ed layer division, elegant styles, delicate and vivid images have been formed, but are still limited in combination of plant species and selection of varieties. In accordance with personal experience in plant landscaping in recent years, the author provided a few suggestions for the optimized confi guration of plant landscapes in southern regions.  相似文献

低碳城市南昌主干道路植物景观评价研究   总被引:1,自引:1,他引:0  
为了明确低碳城市南昌道路植物景观的现状和影响道路植物景观的重要因子,为南昌及中国其他低碳城市道路植物景观规划与设计提供依据。采用描述因子法,选择若干对道路植物景观效果贡献较大的指标,建立了整体指标评价体系。采用景观综合评价指数法模型,通过评价因子的权值确定和指标的量化,对南昌城市主干道路植物景观进行了分析评价。结果表明,南昌市道路植物景观整体建设水平较好,57.14%的道路植物景观评价结果在Ⅱ级以上,III级占35.71%,但也有7.14%的道路在Ⅳ级以下。在所评价的8个因子中,得分最高的是植物景观与硬质景观的和谐性,其次是植物景观与整体环境的协调性,植物生活型结构得分排第3位,这说明南昌城市在整体建设过程中,比较重视植物与道路和周边硬质景观环境的协调与统一,多数路段“乔-灌-草”搭配较为合理;物种多样性和植物观赏特性得分低。南昌城市道路植物景观仍然存在单位空间绿量较低、植物种类应用欠丰富,以及地域特色不太突出等问题。针对评价结果,提出了南昌城市道路低碳植物景观和地域特色植物景观营建的建议与措施。  相似文献

DA-6作为一种高效植物生长物质,对多种农作物具有显著的增产、抗逆、抗病、改善品质、早熟等功效,但有关其对种子活力的影响研究少。以玉米自交系郑58为试验材料,将6g/L DA-6分别于花后0、5、15、25、35d均匀喷施于玉米叶片,研究DA-6对玉米种子活力的影响。结果表明,不同时期喷施DA-6可不同程度增加种子内蛋白质含量,进而影响种子活力。不同时期喷施DA-6使得种子活力与对照存在显著性差异,且随着处理时间延后种子活力逐渐升高。在花后35d处理,其种子活力指数达最大值,为0.77,较对照增加0.10,提高14.8%。因此,在玉米自交系郑58花后35d喷施DA-6可有效提高玉米种子活力。  相似文献

Summary A diallel cross population was created from five clones that were randomly selected from five commercial ultivars of alfalfa (Medicago sativa L.). It was planted out at Edmonton and was studied for forage yield, vigor, growth habit, days to flower, plant height and frost tolerance in 1972 and 1973. Results showed that genetic difference between the five parents were large since the general combining ability (GCA) was more important than specific combining ability (SCA) and reciprocal effects (RE) for all the six characters. Greater genetic variance for forage yield, vigor, growth habit and plant height were observed in the second year of growth rather than in the year of establishment. Thus selection for these characters in the second year would be most effective. Genotype x environment interaction was significant for all characters and was relatively more important in the case of vigor and plant height. A study of the GCA effects showed that this source of variation was due to changes in the order of ranking for GCA effects over the environments. Genotypic correlation of the six characters revealed strong genetic association between forage yield, vigor, growth habit, plant height and frost tolerance in this population of alfalfa.  相似文献

灰飞虱在玉米田空间分布格局及抽样技术研究   总被引:1,自引:1,他引:0  
为了提高监测预报与持续控制水平,应用聚集度指标法测定、Iwao法和Taylor幂法则,研究了浙西北玉米田灰飞虱的空间分布格局和抽样技术。结果表明,灰飞虱在玉米田以聚集分布为主,聚集强度随虫口密度增加而增强。其聚集原因经Blackith种群聚集均数测定,当m<1.8072头/株时,其聚集是由某种环境因素(如气候、生育期、长势等)所引起的;当m≥1.8072头/株时,其聚集是由灰飞虱本身生物学特性与环境因素共同作用引起的,在此基础上提出了理论抽样数和序贯抽样模型。研究结果为田间灰飞虱的准确抽样调查和有效防治提供了科学依据。  相似文献

为探索园林绿化垃圾资源化利用产品在园林绿化和土壤改良中的实际应用效果,进一步推动园林绿化垃圾的资源化利用。本试验分别将园林绿化资源化利用产品——有机肥和生物质炭应用于城市公园的绿化中,选取红花檵木、大叶油草、紫色狼尾草分别作为园林绿化中的灌木和草本的代表性植物,通过测定不同处理中植物的叶绿素含量、株高以及土壤养分来评价园林绿化垃圾资源化利用产品的应用效果。结果显示:有机肥和生物质炭的使用会有效提高3种植株的叶绿素含量,促进植物生长。有机肥对于红花檵木的土壤养分含量的影响并不一致,但是对于土壤含水率和电导率均有不同程度的提高。另外,有机肥和生物质炭会显著提高大叶油草和紫穗狼尾草的土壤养分含量,更加有利于植物生长。本试验在植株生长和土壤养分这一方面为园林绿化垃圾资源化利用产品在园林绿化中的应用提供了理论依据,同时为园林绿化垃圾的资源化利用奠定了基础。后续的研究中要更加深入的在土壤的物理、化学、生物性质三方面进行,进一步充实上述理论依据。  相似文献
