基于栽培實(shí)驗(yàn)的北京鮮花港郁金香展區(qū)改造研究
[Abstract]:Since 2010, the Beijing Flower Port Investment and Development Center has held Tulip Show every year. In recent years, it has been the largest tulip exhibition in Beijing. At present, the main problem is that a large number of seed balls are imported every year and the seed balls degenerate seriously, so the cost of flower exhibition is very high. In addition, the annual tulip flower show landscape convergence, landscape quality also needs to be improved. On the premise of improving the landscape of flower exhibition, how to realize the reuse of some sub-spheres and save the cost of flower exhibition is an urgent problem to be solved. Based on the investigation of the landscape of the tulip flower exhibition in Beijing and the aesthetic tendency of the public towards the common type of tulip landscape, the effects of different planting designs on the growth and flowering of tulip and the regeneration of the tulip ball were studied in this paper. In order to explore the feasibility of the application of tulip ball in flower exhibition, the difference of growth and flowering performance between progeny ball and female ball and the effect of different cultivation measures on the flowering of tulip ball were studied. On the basis of landscape evaluation analysis and cultivation experiment, the planting design suggestion of Tulip flower exhibition in Beijing Flower Port and the local reconstruction scheme of the distribution environment in main exhibition area were put forward. The results are as follows: (1) the results of BIB-LCJ method show that tulips are the main body of the landscape, there are many levels of landscape, color collocation is rich, harmonious or concise atmosphere, and the nearby water body has a higher evaluation of the landscape. There are some aesthetic differences among different groups. In order to meet the aesthetic needs of different populations, the variety of flower exhibition landscape should be constructed. (2) tulips planted under different artificial communities have an effect on their growth, flowering and ball regeneration. Under 'deciduous forest cover' and 'deciduous forest' planting, plant growth is strong, flowering quality is high, landscape effect is good, and it is beneficial to the growth of subsphere. (3) the intercropping experiment of mixed planting shows that white clover is mixed with tulip. The effect of wheat and tulip intercropping on tulip growth and flowering and seed ball regeneration was not significant. (4) the growth and flowering of most cultivars were worse than that of female bulb. However, the flowering effect of some varieties such as' Golden Review 'could meet the requirements of the exhibition, and substrate cultivation (peat: hesha 3: 1 and peat: sand: garden soil 2: 1: 1) could improve the growth and flowering quality of the seed ball. When both mother and seed balls were cultivated by substrate, the quality of flowering was improved more obviously, and different concentrations of GA _ 3 could promote the growth and flowering of seed balls, and the suitable concentration of GA _ 3 was different. 'apricot color impression' is 400 mg / L 'pink impression' and 'gold review' is 600 mg / L. (5) combined with landscape evaluation and cultivation test results, some deciduous tree communities can be appropriately increased in Beijing Huagang Tulip planting area, and mixed with white clover. To provide a favorable environment for the growth of subspheres, to cultivate the subballs in some areas, to improve the application effect of the subballs, to save the cost of flower exhibition from these two aspects, and to construct different communities can create a variety of flower exhibition landscape and improve the landscape effect. In this study, the landscape convergence of tulip flower exhibition, the tulip seed ball degradation caused by the high cost of the flower show. Using BIB-LCJ method to evaluate tulip landscape, the effects of different artificial community types and cultivation measures on tulip growth, flowering and ball regeneration were determined. Based on this, the planting design suggestion of Tulip flower exhibition in Beijing Flower Port and the partial reconstruction scheme of the distribution environment in the main exhibition area are put forward. This research has important guiding significance for holding tulip flower exhibition in various places.
