Experiment of Dutch Tulip Cultivation in Open Field in Shanghai, China—Effect of Temperature Change on Flowering Duration

Abstract

In recent years, a large number of Dutch tulip varieties have been cultivated in the open field of Shanghai Flower Port (The biggest tulip park in China). In this paper, nine tulip varieties’ growth period data were recorded for this experiment. By comparing the flowering duration of different varieties, it is concluded that planting early flowering varieties in Shanghai is more economical. At the end of this paper, by correlation detection method, it is concluded that there is a negative correlation between the flowering duration and temperature in Shanghai, China.
