Ecological Construction And Landscape Planning Of Tea Plantation

Tea is a kind of natural landscape planning,ecological construction and landscape garden is under the premise of ensuring the normal growth of tea and safety of tea quality,ecological landscape reconstruction of tea plantations,create a set of production,processing,sales,comprehensive ecological tea tourism in one.In order to improve the ecological construction of tea plantation,the ecological cycle model of tea garden was constructed,and the preliminary effect was studied in Yangshan new natural tea garden.The ecological landscape planning and design were carried out according to the system.The main results of the research are as follows:(1)Through the literature review,5 kinds of ecological tea garden model were summed up,namely,tea-grass / crop model,tea-bird(goose)model,tea-forest model,tea-forest-grass model,tea-forest-grass-farming(travel / leisure)model.The technical factors of ecological construction of tea plantation were expounded from the aspects of site selection,water conservancy and road network construction,tree planting and greening,ladder wall with grass interplanting and green manure as well as tea plantation management.In view of the problems such as strong weeds,many diseases and insect pests,poor soil fertility and so on,this paper sumed up the ecological cycle model of young tea plantation in combination the ecological model and technical factors of tea planation.Meanwhile,a detailed discussion was carried out from the aspects of weed control,extermination of disease and insect pest,soil fertilization and intelligent monitoring.(2)We had a preliminary study of the effect of ecological cycle model by raising geese,covering sawdust and intercropping crops.Through this survey,it was found that there were 26 kinds and 46 species of weeds in the tea plantation,in which the main weeds were Crabgrass,Ageratum,Conyza canadensis,Paspalum paspaloides and Crassocephalum crepidioides.Thanks to the goose-raising,the weeds in tea plantation were effectively inhibited,and the weed fresh weight was reduced by 0.27kg/m2.Due to the preference of the goose,Goosegrass,Crabgrass,Oldenlandia,Setaria plicata and Compress galingale were obviously decreased.The survey also found that covered with wood shavings,intercropping ryegrass,beans,peas,covered with sawdust + intercropping of ryegrass can effectively control weeds and soil fertility;the best control effect on weeds was the combination of covered with wood shavings + intercropping of ryegrass;the best effect of soil improvement was intercropping of bean and peas;intercropping of perennial ryegrass,beans and snow peas can improve the coverage rate of tea plantation,create a simple three-dimensional composite cultivation mode and optimize the environment of tea plantation.(3)The research results of the young tea plantation ecological cycle model and ecological cycle effect were applied to the planning and design of ecological tea plantation.Based on the analysis of the natural environment and social development needs of the park,the design principles,design ideas and functional zoning were determined.According to local conditions,reasonable planning and design were carried out on the tea plantation road,water conservancy facilities,planting patterns,pest control,ecological monitoring and so on,which will provide reference for the construction of other ecological tea plantation.According to comprehensive research results,it can be concluded that the ecological cycle model of tea garden in young age has an important guiding significance for ecological construction and planning design of young tea plantation.
