土壤是大自然馈送给我们比较珍贵的礼物,但是生活垃圾,各种程度的重金属污染,使得土壤资源受到威胁,今天,我们一起来认识一下常见的3种修复土壤能力比较强的植物。

Soil is nature's most precious gift to us, but living garbage, all kinds of heavy metal pollution makes soil resources threatened. Today, we have a common understanding of the 3 kinds of plants that have the strongest soil remediation capacity.

1、向日葵

向日葵的耐性了得,种植起来十分容易,除了我们平日所知道的观赏功能,和食用价值以及经济价值外,比较让人们震惊的是它的净化价值,我们只知道向日葵对生长的土壤要求不高,却没想到它对土壤具有超强的净化功能,向日葵能够将自己所在的土壤里的有害重金属吸收,之后挥发净化,吸收。

Sunflower terrible patience, grown up very easily, but we usually know the ornamental function, and edible value and economic value, the most shocking people is to purify its value, we only know that the sunflower on the growth of soil is not high, but did not think it has super purification function of soil, sunflower can will their harmful heavy metals in the soil after the volatilization of absorption, purification, absorption.

杨树的树木高大、笔直,树形优美,具有很好的观赏价值,在我国不少北方地区,选择杨树作为行道树。

Poplar trees tall, straight, beautiful tree, has a very good ornamental value, in many northern areas of China, choose poplar as street trees.

除了观赏价值外,不得不提的就是杨树的生态防护功能,著名的三北防护林,就是由杨树为主造林的,杨树的根系十分发达,能够很好的锁住水分和土壤,也正是因为这一特性,使得人们发现了杨树的防风固沙的作用。此外,杨树能够有效的降解土壤中的甲苯等有害物质,对于土壤的修复作用很大。

In addition to ornamental value, I must mention that poplar ecological protection function, the three North Shelterbelt is famous, mainly by poplar afforestation, poplar root system is developed, can be very good to retain water and soil, it is because of this characteristic, the people discovered the role of windbreak and sand fixation of poplar. In addition, poplar can effectively degrade toluene and other harmful substances, and it has great effect on soil remediation.

碧玉妆成一树高,万条垂下绿丝绦。这两句话生动的描绘了绿柳的姿态,柳树的观赏价值很高,而且品种繁多。除了比较常见的园林观赏价值外,还具有很好的经济价值,柳条因它有的柔韧性,可以制作许多的工艺品和生活所需用品。木材通常可用作制造纸张和人工棉。

Jasper makeup into a tree, 10000 dropped the green silk sash. These two sentences vividly depict the posture of green willow, the ornamental value of willow is very high, and the variety is various. In addition to the most common garden ornamental value, but also has a very good economic value, wicker because of its unique flexibility, you can make many crafts and necessities of life. Wood is usually used for making paper and artificial cotton.

治理土壤污染的科学家发现,柳树能够很好的吸收土壤中的污染物,并将之转化,因此具有很好的污染处理功能,对土壤有一定的净化作用。

The soil pollution scientists have found that willow can absorb the pollutants in soil and transform it, so it has a good function of pollution treatment, and has a certain purification effect on soil.

其实,对土壤又修复功能的植物还有很多,但是人类不该将自己的责任委托到植物身上,土壤中的污染物排放来自于我们的工业化发展,保护土壤资源,是我们每个人的责任,而治理污染本身,就是减少排放。

In fact, there are a lot of soil and repair plant, but not the human own responsibility entrusted to plants, soil pollutants emissions come from our industrial development, protection of soil resources, it is everyone's responsibility, which is to reduce emissions of pollution itself.
