Application Of Ornamental Plants In Baoding Greenhouse Parks

Ornamental plants have been widely used,greenhouse as a place for plant collection and cultivation,exists by means of ornamental plants.In recent years,the vigorous development of ecological gardens,botanical gardens and sightseeing agriculture in China has promoted the progress of greenhouse parks,making them a good place for people to go on weekend outings and become increasingly closely related to people's life.The quality of greenhouse parks depends largely on the ornamental plants.Some of the ornamental plants in greenhouse parks in the first-tier cities of China have reached a high level in terms of the richness of plant species or the artistry of landscape.However,the application of ornamental plants in greenhouse parks in more small and medium-sized cities is below the medium level,which can not satisfy the visitors' good indoor environment.It is urgent to improve the application level of ornamental plants in greenhouse parks.In this paper,28 greenhouse parks and their ornamental plants in Baoding were investigated systematically,including 98 families,223 genus and 336 species commonly used ornamental plants.Among them,122 species were used for trees,93 species for shrubs or small trees,16 species for vines,64 species for herbs and ground cover,41 species for ornamental vegetables and medicinal plants respectively.The common ornamental plants were analyzed from three aspects: The ecological characteristics,spatial structure and aesthetic characteristics of ornamental plants.The composition of plant types,proportion of arbor,shrub and grass,application of ornamental parts,division of plant thematic functions,seasonal changes and application of aromatic plants were analyzed,and reasonable suggestions were put forward on plant selection.The plant space construction of greenhouse parks was analyzed from two aspects of horizontal structure and vertical structure,and the plant space types of greenhouse parks were investigated by the method of transect.This paper summarizes the forms of plant community combination,lists 12 common forms of greenhouse plant combination and 38 common examples of greenhouse parks community.Applying the analytic hierarchy process theory in operational research,the evaluation system of ornamental plants in greenhouse parks was established.20 evaluation factors of ornamental plants in greenhouse parks were screened.The weights were calculated by mathematical models.The two greenhouse parks,BaodingAgroecology Botanical Garden and Electric Valley Low Carbon Park were evaluated.The results of plant application investigation in greenhouse parks were obtained.The application level of ornamental plants in two greenhouse parks was evaluated quantitatively and qualitatively with the satisfaction of greenhouse users.Finally,the application effect evaluation scores of ornamental plants in Baoding Agroecology Botanical Garden and Electric Valley Low Carbon Park were 7.32 points and 8.05 points and 10 points respectively,which reached "general" and "good" Two grades,the latter is better than the former in plant application.Based on the application of ornamental plants in Baoding greenhouse parks,this paper comprehensively analyzed the plant species and characteristics commonly used in local greenhouse parks,put forward suggestions for the selection and application of the same type of indoor ornamental plants,and provided reference for the construction of Baoding greenhouse parks.On the basis of previous research and field investigation,the author determined the evaluation factors suitable for ornamental plants in greenhouse parks for this purpose.Reference for application evaluation of type ornamental plants.
