1. Measures: Getting Phalaenopsis through the summer is mainly a matter of cooling, and the following measures should be taken: ① Add a double layer of shade netting to reduce light, which achieves a good cooling effect (a drop of 2°C to 4°C). ② Sprinkle or flood the ground. Summer temperatures are very high, but the water just drawn from a well is actually quite cold, around 16°C. Therefore, sprinkling or flooding can produce an obvious cooling effect. ③ Spray water on the leaves; this cools fastest but lasts the shortest time. ④ Ventilate. On the wall every 5 m

② Sprinkle or flood the ground. Summer temperatures are very high, but the water just drawn from a well is actually quite cold, around 16°C. Therefore, sprinkling or flooding can produce an obvious cooling effect.

③ Spray water on the leaves; this cools fastest but lasts the shortest time.

④ Ventilate. Cut a 40 cm × 40 cm square hole in the wall every 5 m at a height of 70 cm above the ground to increase ventilation and reduce the occurrence of pests and diseases; turn on fans when the temperature is above 25°C to strengthen air circulation, which benefits plant growth.

2. Undesirable phenomena that easily appear during the summer

① Leaf aging and shedding: some lower leaves of the plants decline during the summer, and from late summer to autumn they gradually yellow and drop off.

② Severe pests and diseases, especially when the weather is hot, relative air humidity is too high with no wind, and temperatures are high, which easily leads to diseases such as soft rot, brown spot and viruses.
