i. Plant seedlings are of sufficient size and age at planting to ensure their success
j. Its condition is good in terms of vegetative and root growth and sound from
fractures and pests.
k. Are locally available and require minimal care and costs during their cultivation
and growth. Reproduce easily.
15.3 Plant Cultivation and Use Functions: Environmental
Function
Plants have great value in the urban environment. Its lack or lack of numbers harms
the environmental balance in the region. This role can be summarized in the following
points:
– The plant absorbs carbon dioxide and is one of the main causes of pollution and the
release of oxygen gas. This process is the most important process in the universe.
– Reduce pollution levels from most types of pollutants by absorbing them.
– Plants emit oxygen in the atmosphere through photosynthesis, thereby reducing
the proportion of pollutants.
– Optimizing the atmosphere through the process of transpiration and improvement
of the climate the presence of plants in a place to reduce the temperature, especially
during the summer. It is known that every 1 g of water lost by the plant requires
633 kcal, which the plant withdraws from the surrounding medium, thus lowering
the temperature.
– Relieve the glare of the sun and dazzle the eyes with intense light. Where the leaves
of the trees intercept sunlight, absorbing part of it and reflect some of the other
rays.
– Contribute to the absorption of sounds and reduce the noise, especially in crowded
places in cities and succession.
– Stop sand crawling and reduce desertification.
– Protect cities from severe winds and break their limits.
The studies we conducted in Egypt showed that the shrubs cultivated in Egypt
differ in their application to get rid of carbon dioxide, and some shrubs have greater
efficiency (Table 1).
Bougainvillea glabra is superior to all shrubs that have been studied in the disposal
of carbon dioxide after 5, 10 and 15 min of exposure to this pollutant. The efficiency
value was more than twice that of Hedera helix and thrice as Lantana camara and 4
times as Malvaviscus mollis and 10 times as Nerium oleander.
From this, it is important to plant shrubs intensively in the city parks:
1. Fast growth
2. High efficiency of some varieties to get rid of carbon dioxide that causes global
warming
