Green is the color of life, symbolizing the abundance of vitality. On our beautiful earth, green vegetation has been quietly improving and beautifying the living environment of human beings. Do we feel comfortable when we are away from the city on holidays, strolling by the side, and speeding in the grassy fields? We need green, and the earth needs vegetation.
Green plants are the backbone of ecological balance, because plants can purify sewage, eliminate and attenuate noise, withstand drought and sand fixation, withstand salt and alkali, and withstand waterlogging, and monitor pollution such as sulfur dioxide, fluorine, chlorine, and ammonia. Green vegetation plays an important role in maintaining soil and water. In areas with lush forests, surface runoff only accounts for less than 10% of the total rainfall; during a normal rainfall, the canopy can intercept 15-40% of the rainfall; the water holding capacity of litter can reach 2-4 times its own dry weight; per hectare of forest The soil can store 640-680 tons of water; 50,000 mu of forest is equivalent to a reservoir with a storage capacity of 1 million cubic meters. Not only that, a protective forest belt is built in the wind-damaged area, and the wind speed of green vegetation can be reduced by about 30% within the protective range.
Green plants rely on photosynthesis to maintain growth, absorbing carbon dioxide and releasing oxygen that sustains human life. Through air circulation, indoor air can be better improved. Plants also inhibit various diseases by absorbing and breaking down harmful substances present in the air. According to the survey, there are more negative oxygen ions in the air in the forest area. After being inhaled into the human body, it can regulate the excitation and inhibition process of the cerebral cortex, improve the immunity of the body, and have curative effects on chronic bronchitis and insomnia. There are also many plants that can secrete bactericides to kill surrounding bacteria, such as bactericides secreted by eucalyptus, which can kill tuberculosis and pneumonia bacteria.
The environment we live in is inseparable from green plants, and some green plants or their flowers and fruits can emit fragrant odors. Green plants themselves and flower bonsai can beautify the living environment of human beings and have ornamental effects. Some sensitive plants can also be planted in certain pollution emission areas as indicator plants for air pollution.
In recent years, natural life and outdoor activities away from the city have attracted a lot of attention. And many people go out on weekends to relieve their bad mood. By staying away from the hustle and bustle of the city, we can go to a place close to nature to relax and relieve stress. It can be seen that green plants can not only beautify the environment but also purify our minds and help us release stress.
