净化空气其实我们也能想明白,当今我们的城市都充斥着雾霾和污染等话题,空气污染这个话题的热度也经久不衰,人们的生活每天都在消耗着氧气,还有所有的工业、电器等很多都每天排放着二氧化碳。如果这样消耗下去,我们生活环境的将会越来越糟糕,所以我们就需要各种绿化苗木,各式各样的绿植来维持我们环境的生态平衡。
In fact, we can also understand that today's cities are full of topics such as haze and pollution, and the topic of air pollution has been hot for a long time. People's lives consume oxygen every day, and many industries and electrical appliances emit carbon dioxide every day. If this consumption goes on, our living environment will be worse and worse, so we need all kinds of green seedlings, all kinds of green plants to maintain the ecological balance of our environment.
植物光合作用所制造的氧比呼吸作用所消耗的氧多20倍,所以森林和绿色植物是地球上天然的吸碳制氧工厂。有资料显示,许多工业城市每年1hm2降尘量为5000~10000kg。据bai家测算,1hm2树林1年可吸收各种灰尘达300~900kg,绿地减尘率达37.1%~60%。植物对许多有害气体都有一定的吸收净化作用。据测定,1hm2柳杉每年可吸收二氧化硫720kg,1kg臭椿干叶能吸硫330g。
The oxygen produced by photosynthesis is 20 times more than that consumed by respiration, so forests and green plants are natural carbon absorption and oxygen production plants on earth. Some data show that the annual dust fall amount of 1 hm2 in many industrial cities is 5000 ~ 10000 kg. According to the estimation of Bai family, the forest of 1 hm2 can absorb 300 ~ 900 kg of dust in one year, and the dust reduction rate of green land is 37.1% ~ 60%. Plants can absorb and purify many harmful gases. According to the measurement, 1 m2 Cryptomeria fortunei can absorb 720 kg sulfur dioxide per year, and 1 kg Ailanthus altissima dry leaves can absorb 330 g sulfur dioxide per year.
净化土壤其实农民或者专家更能明白这个问题,植物的地下根系能吸收大量有害物质,而且有净化土壤的能力。而且我们也听说过,很多地里种几年玉米之后,会为了让土壤的肥力或者成分变得更好,而选择种植其它不同作物来让我们的土壤变得更好。
In fact, farmers or experts can understand this problem better. The underground roots of plants can absorb a lot of harmful substances and have the ability to purify the soil. Moreover, we have heard that after a few years of planting corn in many fields, we will choose to plant different crops to make our soil better in order to make the soil fertility or composition better.
