Study On The Application Of Landscape Plant Varieties In Tianjin Area

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.
