Research And Development Of New Plant Vertical Greening System

With the rapid development of the city,more and more tall buildings are built,and the population density is increasing,but the green plants in the city are less and less,and the air pollution index is growing exponentially.The heat island benefits of the city make the high temperature weather in the city longer and longer,and the extreme high temperature weather is constantly refreshed.There is an unwritten general term for this series of problems-"city" City disease ".Moreover,urban diseases incidence has seriously affected the health of people living in city and city,and the inciden ce rate of various serious diseases in cities is increasing.The main reason is that the living space and facilities required by the dense population in the city,as well as a large number of industrial production enterprises,occupy the green living space of human beings in the limited land space.The contradiction between land consumption and green resources is irreconcilable.How to alleviate this kind of contradiction is a subject that everyone living in the city needs to think about seriously.In the city,we can greatly alleviate the "urban disease" by expanding the green living space of the city to the maximum extent.Use the photosynthesis of plants to absorb carbon dioxide in the city and discharge oxygen;use the absorption capacity of plants to absorb vehicle exhaust gas in the city;use the dust reduction capacity of plants to absorb dust to reduce haze and various suspended particles in the city;use the absorption and degradation capacity of plants to indoor formaldehyde and other harmful gases To achieve the purpose of purifying the toxic and harmful substances in people’s living environment.Therefore,only by vigorously promoting and increasing the number and coverage of green plants in cities,can we achieve the goal of alleviating urban diseases.How to solve the contradiction between green plants and land supply and demand?Only to develop into the air and expand the three-dimensional planting space of plants.All kinds of suitable plants are planted on the facade and roof of buildings in cities;the partition belt of urban roads is replaced by plant fences;plants are covered on and off the parking lot;the bridge guardrail and sound insulation screen are replaced by hanging plant guardrails or plant sound barrier screens;The interior and exterior walls of people’s houses and various public buildings will no longer be filled and separated with building materials(such as clay bricks and aerated concrete blocks),but replaced with various plant walls.In this way,all the spaces we live in are green oceans and kingdom of plants.Only in this way can we cure the "urban disease".First of all,the paper analyzes the origin of vertical greening and the existing technology,analyzes the advantages and disadvantages of various vertical greening technologies,and conducts in-depth research on the vertical greening planting module technology,with a large number of key details in the planting module.In the development of modular planting box,modular root fixation system,selection of planting soil,selection of vertical greening plants,dry hanging technology of planting modules,maintenance system of vertical greening plants,etc.,a complete set of practical vertical greening planting system is designed and developed.At the same time,on the basis of vegetative soil planting,a set of upgraded vertical planting system of soilless cultivation method is creatively developed,that is,"fog culture" technology is applied to the vertical greening system,which can reduce the self weight of planting module,expand the extension space of plant roots,and reduce the transmission risk of soil borne diseases and pests in the soil culture system.In the process of research,the paper also uses the theory and method of project management to implement the development and research of this subject as a project process,uses the WBS theory and method of project management to decompose the project structure,decomposes the research subject to the smallest unit,decomposes every detail of the planting module system step by step,and studies the best technical scheme,Make the vertical greening system indicators tend to be perfect.
