The application of carbon dioxide in field crops such as rice and sorghum can also significantly increase production. However, there is no report on the application of carbon dioxide to orchards from the existing data. In June this year, we conducted a carbon dioxide test at Dwarven Pear Tree Park. The results are as follows:
