| In recent years,with the increasing demand for environmental quality,the concept of "ecological garden" and the successive opening of urban green parks,ecological garden is not the accumulation of green plants,not simply return to simplicity,but the artistic configuration of the ecological communities on the basis of aesthetics,which is the further development of garden art.Raise.In the growth cycle of plants,the "four hours of harvest" can achieve the effect of "infinite state and unswinable spring",which can enrich the beauty of the community and enhance the ornamental value.The existing plant landscape configuration and landscape construction have been unable to meet the requirements of people’s natural landscape and ecological beauty.Let people begin to explore and study the new ground cover plants.The ground branches are strong,clustered,densely colored,and rich in color.They are suitable for various garden applications,such as floral,flower beds,decorative courtyards,beautification rooms and landscaping.It has become an inevitable trend to combine it with urban parks and landscape configuration.Based on the study of the ground cover chrysanthemum abroad,we find that there are exact,mature and complete systems and relevant laws and regulations in the theory and practice of Chrysanthemum morifolium abroad.Good results have been achieved through successful practice.However,the domestic research started a little late,and the actual research on ground cover chrysanthemum is very few.This is only the initial exploration stage of practice.The application of ground cover chrysanthemum has not been widely applied in the whole country.In this study,the research progress of ground cover chrysanthemum,the content and application of ground cover chrysanthemum were studied through literature review,field investigation and induction,and the theory of combining chrysanthemum and landscape design was explored.Ground cover chrysanthemum is an excellent perennial flower with environmental benefits,social benefits and economic benefits.It has the comprehensive function of afforestation,beautification and coloring,and is the foundation of Chrysanthemum Culture in China.Compared with other garden plants,ground cover chrysanthemum has strong adaptability to various environments.The ground cover chrysanthemum is not strict with water and fertilizer requirements after planting.It needs no pruning,extensive management and low maintenance cost.As long as proper weeding is carried out,and it is relatively less infected by chrysanthemum diseases,it basically does not spray pesticides.In addition,chrysanthemum as a perennial flower plant can bloom for many years,which is conducive to the wide use of landscape.Based on the theoretical research of ground cover chrysanthemum and the background of ground cover plants in Xi’an area,four species of ground cover chrysanthemum in Xi’an area were introduced and applied.Through the introduction and breeding of four ground cover chrysanthemums,the following conclusions are drawn.1.Through the analysis of the introduction and breeding of four ground cover chrysanthemum varieties,it is concluded that four ground cover chrysanthemum varieties sprout in mid March,and grow vigorously in 5.6 months.They are buds in September and bloom for more than 100 days.The florescence is the same,the cold tolerance is the same,the ornamental effect can be unified,and the landscape is more harmonious.Four kinds of ground cover chrysanthemums display magnificent and grand visual beauty to visitors in the Xi’an botanical garden National Day flower show..2.This experiment summarized and analyzed the breeding and Cultivation Techniques of four ground cover chrysanthemums.ABT promoted the formation of callus by cutting branches of ground cover chrysanthemum,and promoted root differentiation effectively.Under the conditions of this experiment,the best ABT rooting rate was 500mg/ L.In 0 ~ 40 s,the survival rate of the ground cover chrysanthemum cuttings,the average root length and the average weight of new roots increased significantly with the prolongation of soaking time and then decreased.Therefore,the best treatment plan to promote cuttings rooting and increase cuttings survival rate is to soak 40 s with 500mg/L ABT solution.Plant growth,development,differentiation and flowering are closely related to environmental factors such as sunshine,air temperature and cultivation.The growth and development of ground cover chrysanthemum is very sensitive to the length and intensity of sunshine.However,the sunshine and temperature required by different varieties and types are different.Ground cover chrysanthemum is a special group of Compositae.Lack Light,plants are easy to grow.However,as a whole,ground cover chrysanthemum is tolerant to semi shade and cloudy environment,and can grow and open under the full light environment of 50%-75%.Kang Pu,urea and potassium dihydrogen phosphate are suitable for popularization and application of ground cover chrysanthemum foliar fertilizer,which is cheap and easy to use.The growth of ground cover chrysanthemum was vigorous by applying different foliar fertilizers,especially with the application of carbuncle and potassium dihydrogen phosphate.The flowers were very bright and the ornamental effect was greatly improved.Urea application had the most obvious effect on the leaves of ground cover chrysanthemum,and the leaves increased dark green leaves.Kang PO or potassium dihydrogen phosphate promoted flower bud differentiation and flower buds increased.Standardized management techniques for ground cover chrysanthemum cultivation in Xi’an area were explored and discovered.3.This study investigates and analyzes the application status of ground cover plants and ground cover chrysanthemums in Xi’an area,summarizes the application methods of ground cover plants,and puts forward some problems and suggestions for the application of landscape plants in Xi’an.At present,the ground cover chrysanthemum in Xi’an is mainly used in flower bed planting,but the application area is very small.In addition,chrysanthemum is mainly used to display flowers for festivals.This study first investigates the application and allocation of ground cover chrysanthemum in Xi’an area,analyzes the application status of ground cover chrysanthemum,and preliminarily studies the application of landscape cover in Xi’an area.The arrangement of ground cover chrysanthemum and its combination with various elements in gardens are summarized.Ground cover chrysanthemum has many uses,not only for ground cover plants,but also for tea drinking.It can also decorate the indoor environment,such as flower arranging,potting,etc.The plants are low,long flowering,dense flowers,rich crown,rich color,strong resistance,extensive management and low maintenance cost.Strong drought tolerance is a good plant material for building economical gardens.Many experiments proved that Chrysanthemum morifolium has certain resistance to sulfur dioxide and chlorine.It is suitable for purifying air and adsorbing dust in factories and mining areas.Ground cover chrysanthemum is very adaptable to environment. |
