The Chongming District Information Office said that flower seedlings have been planted in the 70,000 m2 smart greenhouse in the Flower Expo Park, and they will bloom during the 10th China Flower Expo 2021. The greenhouse is equipped with precise temperature control and is highly intelligent. It can automatically water, fertilize, and move the seedbed. The 70,000 m2 greenhouse only needs 10 staff to fully operate. Indoor and outdoor reserved flowers will be transplanted to various places in the Flower Expo Park before the opening of the Flower Expo 2021.
According to the reports, a total of more than 20,000 m2 of greenhouses have begun to reserve flowers, planted with impatiens, anthurium, and other varieties. These flower seedlings can survive the cold winter in the greenhouse and are temperature-controlled to bloom during the Expo. In addition, outdoors, 50,000 pots of hydrangea and more than 1,000 stump-type roses(Rosa chinensis Jacq) have also entered the reserve and conservation.
In the early stage, the flower team of the Flower Expo conducted a trial planting of more than 2500 kinds of flowers. In addition to having advantageous appearances, these flowers have to adapt to local climatic conditions and the flowering period can be controlled during the period of the flower expo to achieve the best effect of a fully blooming garden. After selection, a total of more than 1,000 flower varieties were selected for use in 98 flower attractions and more than 200 flower spots in the Flower Expo. For example, the lotus flower that is loved by the public usually has its flowering period after July, but at that time the flower expo would have already finished. Through repeated experiments and temperature control, the flower team found that the flowering period of the lotus can be advanced to May. This makes this kind of "flower star" caught up with the last chance to enter the Flower Expo.
According to the plan, the flower construction area of the Flower Expo 2021 will reach 1.2 million m2, including 110,000 m2 as the boutique area, and more than 20 million flower seedlings need to be planted.
