How the leaves of orchids are green and bright

Author: Xu Yao

The so-called orchid leaves are bright, clean and complete, which is not only the standard of constant orchid health, but also a kind of examination of dill orchid craftsmanship. although the orchids planted by many orchids seem to be healthy, their seedlings are normal, but the leaves are rough and dull, water stains, medicine stains, dust and so on seriously pollute the leaves, so it is difficult for such orchid seedlings to enter the elegant hall even if they are expensive! There is a loss of orchid wind, the appearance is very low! At the trust of Lanyou, the author introduces a few experiences for Lanyou for reference. Please correct me if you don't trust me.

Briefly state a few points:

1. Spray foliar water should be clean, no or less impurities (the author practice, long-term use of tap water will produce dirt after spraying leaves, the solution is to add appropriate edible white vinegar to the tap water, let it sit for more than two days, lightly take the precipitate on the surface), you can also use the TDS meter for water quality testing (water soluble conductivity value), the lower the value means the purer the water quality! The original value of tap water is between 50 and 300.

two。 Foliar sterilization can not be too much, the general efficacy residues are more than 15 murmur20 days, do not repeat the application of pesticides during the interval, if orchids have been infected with bacteria, must be isolated management, after the orchid Yeshu return to the orchid room for normal management; it is recommended that water-based fungicides should be used as far as possible.

3. Increase the relative air humidity of the orchid room to prevent dry wind / hot wind / strong wind from damaging the orchid leaves; if the orchid is raised on the roof or balcony, the corresponding humidifying equipment should be added to carry out microclimate intervention to keep the air humidity at about 70% and 80%.

4. Close the orchid room, reduce the dust into the orchid room and pollute the leaves; if possible, use wet curtains to filter the dirty air entered by the outside world; make the orchid room air moist and refreshing! There is the use of gas exchange and orchid growth!

5. It is recommended to apply foliar fertilizer for foliage plants with comprehensive micro-fertilizer, which can dissolve quickly, absorb well, have no residue, and will not cause foliar pollution; a large number of elements such as urea and phosphorus dipotassium are best used in pot application, and if you need to apply them outside the root, they should not be too flat. Foliar application of a large number of elements is no more than 12 times a year, that is to say, at most once a month, including growing and dormant periods!

6, regularly flood the orchid, clean the leaves to prevent medicine stains, inorganic salt accumulation of harmful substances and impurities! Ventilation should be urgent after each shower, blow-dry the water in the leaf clip to prevent rotten heart, pay more attention to the bud stage!
