Fresh air and its importance.
Conditions necessary for the life of the plant growth, must ensure that the plants respiration - the exchange of plant tissues of oxygen and carbon dioxide. Around us, and therefore the plants, the air is at 4 / 5 of the nitrogen and about 1 / 5 of oxygen. In addition to these gases, the air contains water vapor and dust. Sometimes in the air can also contain harmful gases, both for humans and plants, such as sulfur dioxide, etc.
Plants by 45% composed of carbon (by dry weight), and source of carbon in plant tissue is carbon dioxide, air and to a lesser extent carbon dioxide from the soil. The carbon dioxide absorbed by plants during photosynthesis, creating the complex organic matter (carbohydrates, proteins, fats, etc.) from which the plant develops its tissues and organs. The process of photosynthesis occurs in plant tissues only during daylight hours. In this case, photosynthesis takes place more in the leaves of plants.
Oxygen is essential for plant respiration. In the process of respiration of organic matter created by photosynthesis disintegrate. Respiration of plants occurs constantly, no matter what time of day. In the process of respiration produces carbon dioxide, water and some energy. Breathing process peculiar to all parts of the plant, but to varying degrees. For example, the flowers breathe more than the leaves, and leaves more than stems.
Processes of photosynthesis and respiration is largely dependent on the intensity of illumination. With enough good light photosynthesis prevails over respiration, and the plant grows well and develops. By reducing the light breathing process, predominates over the process of photosynthesis, thus it is accompanied by loss of organic matter. This often happens in winter when the plant is not enough light, it is bad or not growing. If shrinking and stretch the leaves, then we say that the plant was "fast." In this case, root feeding will not do or anything but harm, because (it was mentioned above), carbon dioxide must be assimilated by the leaves. Therefore, simply rearrange the plants closer to the light.
The air in the apartments.
As a rule, virtually all indoor plants are good for fresh air, despite the fact that green leaves themselves produce oxygen. For cacti, such as regular airing, mainly in the summer - the key to success in their content. Very sensitive plants can respond to noxious fumes that are expelled by painting. The kitchen should not be put plants in the immediate vicinity of the plate, because the plant can reach the hot steam from a boiling kettle or saucepan. However, almost all plants are afraid of cold drafts, especially with sudden temperature changes.
In this case, refers to drafts in the winter. Sometimes they write that there are plants that can tolerate drafts, but if the plant is growing in a warm room, it just gets used to this content and harm from a draft can be applied to even the most undemanding plant. Of course, a few minutes of ventilation the room, the plants can not hurt, but if the plant is several hours at an open window in a cool or just windy, it is not surprising that even the most demanding of the plants did not throw off not only the buds, but also leaves.
Fresh air in summer.
There are plants that make the summer better than the balcony, or planted in open ground, so that with the onset of cold weather in the pot and transplanted back into the room. These lovers of fresh air are: acacia, pomegranate, jasmine, laurel, Ivan wet, passion fruit, citrus fruit, yucca, and many others. When transferring plants to fresh air, keep in mind that plants have to adapt not only to the coverage, but also to wind, temperature changes at night, and rain. Upon returning home, plants with the onset of autumn frosts, do not forget to check them out at random presence of pests. After all, you can bring in from the garden slugs, earwigs, millipedes and other insects is not pleasant, and arthropods.
Some people wonder how much harmful carbon dioxide plants and how much they produce it. In fact, the amount released in the breath of plant carbon dioxide is too insignificant to bring a nuisance, or even more, harm to humans. If the average person produces per day, about 900 g of carbon dioxide, the same amount of carbon dioxide produces around 600 small plants. The ability of plants to provide water during respiration plays a positive role for humans, as thus is a natural humidifying the air, albeit in a rather small degree, if you take one plant.
I must say that the influx of fresh air is needed not only ground plant parts, oxygen access is required and roots. Not all, but many of the plants love it when they loosen the soil, especially if formed on the surface salt crust. Loosen the soil should be cautious, trying not to damage the roots. Dust on the leaves as they are closed by light and, therefore, in this case violated gas exchange. Therefore, the possible need to wipe the leaves of plants, and plants with small leaves plenty of spray (spraying if applicable) so that the water washed away the dust. In plants with pubescent leaves that do not like spraying, the dust can be swept away light brush.
All ferns and members of the family Gesneriaceae not tolerate cigarette smoke. Ventilated room, do not forget to close the door to reduce the draft and move the plant to a safe place. Particularly sensitive plants to make better in another room. If the plant is on the floor, even if not at the window, it can also suffer from the cold air. So if it's cold and wind, and to ventilate the room, you'd better open the door to another room where there are no plants, and there open a window. Enough air flow that would refresh the apartment.
