Illuminating Phalaenopsis does not like strong light, and requires a half shade environment. According to the growing environment, the light is required to be between 1500 and 3000Lx. If the light is too strong, it is easy to be burned. When the light is weak or the sunshine time is too short, you can increase the light time appropriately, which can increase the quality of flowering.
Temperature 20 ℃ ~ 25 ℃ is the most suitable temperature for Phalaenopsis growth. In order to ensure the normal growth of Phalaenopsis, the temperature in winter should not be lower than 15 ℃, it is best to keep above 20 ℃, summer temperature can not be higher than 35 ℃. When the temperature is too high, the temperature should be lowered in time, and when it is too low, the temperature should be increased in time.
Moisture Phalaenopsis loves water but is afraid of waterlogging. Be sure to wait until the soil starts to dry before watering it. Be sure to pour all the soil through when watering. The accumulated water in the leaf sheath easily breeds bacteria, and anthrax and leaf spot will appear.
Humidity Humidity corresponds to temperature. When the temperature is high in summer, the air humidity should be kept above 85% to ensure the normal growth of Phalaenopsis. When the temperature is too low in winter, the humidity is adjusted to about 80%.
Fertilization Phalaenopsis can be directly applied with compound fertilizers and nitrogen fertilizers. In the peak season, water and fertilizers can be appropriately increased. The fertilizer and water should be light or not concentrated, and a small amount of multiple times is suitable. Thin fertilizers should be applied diligently, not in bad weather, and too wet in the root circle. Keep air convection when fertilizing to avoid suffocation when the root circle is soaked in water for too long.
Substrates Substrate cultivation is mainly divided into solid substrates, liquid substrates, and gas substrates. The root system of the plant is on the one hand a supporting role, on the other hand, it is also used to absorb nutrients. During the planting of Phalaenopsis, soilless substrates such as mosses and algae are mainly used, which has good water absorption effect and strong permeability. If soil cultivation is used, choose a weakly acidic soil with better air permeability.
Prevention of diseases and insect pests Common diseases and insect pests of Phalaenopsis mainly include anthracnose, root rot, brown spot disease, etc., and the principle of prevention is mainly adopted. During the planting process, proper ventilation should be maintained, the placement density should be reasonably controlled, the environment should be kept clean, and regular attention should be paid to spraying insecticides and fungicides. If diseased plants are found, diseased leaves and debris should be removed in time, and plants with severe disease should be isolated or even destroyed to prevent the spread of diseases and insect pests.
Facilities Because Phalaenopsis has high requirements on temperature and humidity, it is recommended to use intelligent greenhouses during the planting process, which can be automatically adjusted at any time according to light, temperature, humidity and other conditions.
