1. Melon requires very high temperature, and the temperature in Jinghai area is more suitable.

2. With intelligent heating equipment in Jinghai District, the greenhouse temperature can be increased, which not only prevents melon from cracking, but also enables melons to be put on the market 7 to 10 days in advance.

3. "Smart greenhouse" pilot. Different from ordinary greenhouses, "smart greenhouses" deeply integrate agriculture with science and technology, and install clean energy (methanol) intelligent heating, gas supply and fertilization equipment, which is not only more environmentally friendly, but also ensures the yield and quality of melons.
