During this period, it is necessary to scientifically control the water content, and there are obvious symptoms of water shortage that can be poured into small water. After watering, pay attention to ventilation, reduce air temperature, and prevent diseases. In order to prevent the occurrence of blight, blight and other diseases, a small amount of Wanqin-Jun-ling can be used to irrigate the root twice; for the prevention and treatment of diseases of the leaves, it can be sprayed with thiophanate-methyl or chlorothalonil every 7 days.
