In the past few days, the continuous plum rain brought abundant rain to the plants. Huangmei Tian's hot and humid climate is prone to mold and harmful insects, and large numbers of breeding termites can cause serious damage to trees. Wang Yuqin, a senior engineer at the Shanghai Botanical Garden, specifically proposed to the public.
■Plant moulds planted in open fields are the “top enemy†of plants in the rainy season. Wang Yuqin suggested that for plants planted in open fields, it is necessary to pay attention to strengthening inspections to see whether there is poor drainage or local accumulation of water. Without timely removal of stagnant water, plants may rot. Occasionally, when the summer comes, there will be a sudden death.
■The key to the maintenance of potted plants and flowers and potted plants lies in reasonable watering, light ventilation and pest control. At temperatures above 30°C, flowers that are dormant or semi-dormant need to be watered down. It is better to water before 10 o'clock or after 16 o'clock.
At high temperatures, in the event of sudden storms followed by fine rain, it is best to move the potted flowers to sheltered ventilated areas. If it is difficult to move, place the pelvic floor and remove the water tray. Create drainage ventilation conditions to avoid direct exposure after the rain.
The rainy season is a season with many diseases and insect pests. The most common pests are spider mites, aphids, and scale insects, which can be sprayed with omethoate. Affected by high temperature and heavy rain, flowers and trees are most susceptible to fungal infections, rose and other black spots are easy to occur, and carbendazim is a universal control agent.
