The use of green radish
1. As a large green plant, the green radish can absorb formaldehyde and trichloroethylene in the air like chlorophytum and Chang Tengchun, and it is the most environmentally friendly air purifier. A pot of green radish is most suitable for a newly renovated house. It is widely rumored on the Internet that the green radish is not a treasure trove of geomantic omen, which has no influence on the geomantic omen at home. Actually, it's not. Green radish has a shadow on home style;
2. Green radish is usually placed in the living room, aisle, restaurant or balcony at home. It will not bring anything unlucky, nor will it take away our oxygen. It can absorb harmful substances in the air, such as strange gas or kitchen fume, and absorb formaldehyde and trichloroethylene released after renovation of new houses. Sexual preference for warm and humid environment requires loose, fertile and well-drained soil. Fertile, loose and well-drained humus soil should be selected for potted green radish, and acidic soil is the best. Green radish is extremely resistant to shade, and can be placed in the sunny place in the indoor seasons;
3. Put a few or more green radish indoors, let him absorb the harmful gas inside, and then live in it for a period of time. From this point of view, the green radish has blocked a lot of toxic substances for us, and its function has far exceeded the simple feng shui function;
Green radish can attract wind and ventilate the room. You may find it puzzling to say this, because plants themselves breathe, absorb carbon dioxide and exhale oxygen. Green radish is usually placed by the window. When the wind is too strong outside, it will block out a little. If there is no wind, it will also release new oxygen. Oxygen enters our living space, which makes us more energetic and the indoor air fresher.
The reason why the leaves of radish turn yellow
1: improper watering
Too much or too little watering will cause the leaves to turn yellow. This special identification method can be used to observe the yellowing characteristics of radish leaves. If the tip or edge of the leaf is dry, the new tender leaves grow normally, and the old leaves wither and fall off, which means insufficient watering. On the contrary, if the leaves are dark yellow and dull, the newly grown tips will not shrink for a long time, which may be due to excessive watering. You can also judge according to your own watering amount;
2. Sunshine problem
Green radish doesn't like too much sunshine, but prefers a cool environment, which is why it can grow well indoors. So, if you just put the green radish in a place where you can receive direct sunlight for a long time, you can probably find out the reason why the green radish leaves turn yellow. However, extremes meet. If there is insufficient sunshine in your hometown, the yellow leaves of green radish may also be caused by insufficient chlorophyll synthesis.
Step 3 apply fertilizer
The effect of fertilization on the yellowing of radish leaves should also be considered in two extremes. Excessive fertilization, leaves hypertrophy, loss of luster, old leaves yellow and fall off; Insufficient fertilization, especially the lack of nitrogen fertilizer, makes the color of leaves pale, then light green, and then gradually yellow. The root leaves turn yellow first, and the top leaves still retain the texture.
