How to Clean the Leaves of Orchids
Orchids, as elegant ornamental plants, the cleanliness of their leaves directly affects the efficiency of photosynthesis and their ornamental value. This article systematically analyzes three professional-level leaf cleaning methods and extends related maintenance knowledge to help you cultivate healthy orchids with shiny leaves.
Three Core Techniques for Cleaning Orchid Leaves
Natural Rainwater Purification Method
March to May in spring is the best period for rainwater cleaning. The pH value of rainwater is neutral and contains nitrogen elements, which can not only remove dust but also supplement nutrients. It is recommended to choose a continuous light rain of more than 3 hours, avoiding heavy rain冲击 that may damage the leaf veins. After cleaning, immediately use a blower to remove the accumulated water in the leaf core to prevent rot.
Artificial Spraying Cleaning Technique
During non-rainy seasons, the water storage spraying method can be used: use a 0.3mm diameter nozzle to spray evenly at a 45-degree angle. Focus on cleaning the back of the leaves where the stomata are dense, and the operation should not exceed 2 times per week. It should be配合 with an散射 light environment of 800-1500Lux to ensure that the water evaporates within 2 hours. In winter, it is recommended to use warm water at 25℃.
Watering and Maintenance Collaboration Method
Use the "Three-Stage Watering Method": first, water the potting soil thoroughly, wait for the excess water to drain, then clean with a second spray, and finally use a cotton swab to handle the accumulated water in the leaf axils. Pay attention to adjust the strategy according to the type of planting material: pine bark substrate can be soaked once a month, and volcanic rock substrate is recommended to be maintained with pure spraying. Combined with EM bacterial solution irrigation once a month, it can enhance the defense of the leaf cuticle.
Analysis of Advanced Maintenance Points
After cleaning, maintenance needs to note: maintain a day and night temperature difference of 8-10℃, and keep the humidity fluctuation range within ±15%. Wipe the leaf surface with a diluted beer solution (100 times) every month to increase the thickness of the wax layer on the leaf surface. If leaf spots are found, immediately treat them with a 1000-fold solution of carbendazim to block the transmission途径 of the pathogen.
By combining scientific cleaning with systematic maintenance, the leaves of orchids can maintain optimal light transmission. It is recommended to establish a maintenance log, record the changes in the leaves after each cleaning, and gradually optimize the personalized maintenance plan to allow orchids to show their elegant posture.
