How can I make the orchid leaves bright and green?

The so-called flowering for several days, the remaining leaves of the leaves, the bright and clean and completeness of the blue leaves, not only the standard of the constant orchid health process, but also a kind of examination of the skills of the cypress orchids; It seems to be healthy, and the hair is also normal, but the leaves are rough and dull, and there are water stains, drug stains, dust, etc., which seriously pollute the leaves. Even such a noble product is difficult to log in to the elegant hall! There is a loss of blue wind, the appearance is very low! Ying Lanyou's support on this issue, the author introduces a few small experiences for the reference of Lanyou! Please do not hesitate!

Simply explain a few notes:

1. The water sprayed on the leaf surface should be clean and contain no or little impurities. (I practice it. After using the tap water for a long time, it will produce dirt. The solution is to add tap water to the appropriate edible white vinegar and let it sit for more than two days. Take the water on the surface to check the water quality test (water conductivity of the dissolved matter). The lower the value, the purer the water quality! The original value of tap water is between 50-300.

2, foliar sterilization can not be too much, the general efficacy of residues are more than 15-20 days, do not repeat the application of pesticides during the interval, if there are orchids have been infected with bacteria, must be isolated management, wait for the orchid after the Yu Yu back Lanfang is under normal management; it is recommended to apply water-based bactericidal drugs as much as possible.

3. Increase the relative air humidity of the blue room to prevent the dry air/hot air/high wind from blowing the damaged blue leaves; for example, the roof or balcony should raise the corresponding humidification equipment for microclimate intervention and keep the air humidity at 70%--80%. .

4, closed the blue room, reduce dust into the blue room contaminated leaves; conditionally use the wet curtain to filter the outside entering the dirty air; make the blue room air moist and fresh! 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, dissolve quickly, absorb well, no residue, no leaf surface pollution; a large number of elements such as urea, phosphorus dipotassium, is best used for potting, such as It needs to be applied outside the roots, and it should not be over-flat. The annual application of a large number of elements on the foliar no more than twelve times, that is to say, at most once a month, this includes the growth period and the dormant period!

6, regular large water shower orchids, clean the leaves, prevent drug stains, inorganic salt accumulation of harmful substances and impurities! Every time after showering, rush to ventilate, dry the water in the leaf folder to prevent rotten heart, buds Pay more attention to the period!

Micro Laser Distance Sensor

New product of U85 micro laser distance sensors use highly focused class 2 laser to detect objects or measure distances, and can return a measured value via varieties intface( serial, usb, rs232, rs485, bluetooth etc.). The electronic distance sensor is a very small Laser Distance Sensor, but high resolution up to 1mm and long distance measuring sensor - teachable measuring range of up to 30m. Extremely accurate distance sensing sensors, errors down to ± 1mm. And the mini sensors and measurements support continuous measurement function, great for compact solutions(eg: robots) with the smallest Laser Distance Sensor of the world!

Parameters of U85:

Mini Laser Distance Sensor,Optical Laser Distance Sensor,Smallest Laser Range Sonsor,Laser Measuring Sensor
