【摘要】 天津市土地的盐渍化面积已经达到了7800平方公里,占天津市总面积的65.8%,因此,天津市的园林绿化建设抵抗盐碱是重大课题,而园林植物品种应用的研究就显得尤为重要。本文以天津市静海县子牙循环经济产业园区5年的绿化建设实践为例,结合前人对植物品种的研究成果,对子牙循环经济产业园区栽植的所有苗木的成活率以及耐盐碱性、耐水湿性、抗病虫能力、观赏性和生态效益、主要应用方式、养护管理注意事项等性状及表现进行了细致的研究,选择出适宜的苗木品种,并建立了该地区的苗木库。基于以上研究,提出采用一个方程式的、简单容易操作的苗木品种选择方法——“排除法”,为每一项绿化景观工程选择苗木品种,从而提高苗木的成活率。本文的研究内容主要包括以下四个方面:1、介绍天津市静海区子牙循环经济产业园区的环境条件。2、苗木适应性调查。为了选择出在园区表现优异的园林植物种类,选取园区的苗木基地、南常快速路道路绿化和子牙示范小城镇安置区一期A-K地块小区绿化这三项园区具有代表性的绿化工程作为绿化植物种类综合评价的对象。这三项工程共栽植了乔木41种501653株,灌木47种955333株/平米,地被17种64758平米,共计1521744株/平米。选取这些绿化工程苗木栽植完成5年后的成活率以及耐盐碱性、耐水湿性、抗病虫能力、观赏性和生态效益等指标进行综合评价,选出在园区表现良好的苗木品种,并建立苗木库。3、提出一种可以在园林绿化中广泛应用的苗木品种选择方法——“排除法”,并以天津市静海区子牙循环经济产业园区在2015年进行的林下带温室大棚周边绿化景观工程建设为例,说明排除法在实际的绿化工程中的应用。4、总结出提高盐碱地种植苗木成活率和增强苗木长势的土壤改良措施、浇灌施肥措施、整形修剪措施和反季节栽植措施。更多还原

【Abstract】 In the city of Tianjin apprentice salinization area has reached 7800 square kilometers,salinization area accounted for 65.8% of the total area of Tianjin City,the landscaping of Tianjin salt tolerance is a major issue,so the research and application of garden plants in Tianjin city is particularly important.This paper takes Jinghai County of Tianjin Ziya circular economy industrial park 5 years of afforestation practice as an example,combining the results of previous studies on plant varieties,planting Ziya circular economy industrial park all the seedling survival rate and salt tolerance,water tolerance,pest resistance,ornamental and ecological benefits,the main application the way,maintenance management attention traits and performance were studied in detail,in order to establish the base of the seedling area.Then the "exclusion" selection of seedling varieties of each landscape greening projects should be selected,provide varieties of seedlings to select a formula style,simple and easy to operate for each greening projects,so as to improve the survival rate of seedlings.1.The environmental conditions of Ziya circular economy industrial park in Jinghai District of Tianjin city are introduced.2,in order to select excellent seedling adaptability of garden plant species in the park,the park nursery stock base,Nan Chang Expressway road greening and Ziya demonstration small town resettlement area a A-K block of the three park green area representative greening project as object of green plant species of comprehensive evaluation,this three projects were planted 41 trees of 501653 strains,955333 strains of 47 species of shrubs was 17 / square meters,64758 square meters,a total of 1521744 plants per square meters.According to the green project completion of seedling planting survival rate after 5 years,salt tolerance,water tolerance,pest resistance,comprehensive evaluation of the performance of good seedling varieties in the park,the establishment of nursery stock base with these seedlings,establish the landscape construction of the library after the seedlings choose from the seedling nursery base.3,put forward a kind of seedling varieties can be widely used in landscaping selection method named "exclusion",and in Tianjin city Jinghai District Ziya circular economy industrial park in 2015 under the forest with greenhouse landscape around the project construction as an example to illustrate the application method of elimination method in actual engineering in green.4.Summarize the soil improvement measures,plastic pruning measures and off-season planting measures on the saline alkali land to improve the survival rate of seedlings and enhance the growth of seedlings.更多还原
