在巴西的一些城市中,人们看到了一些绿色的墙,墙上的绿草随风掠过,犹如一片绿色的垂直海洋,这是巴西独特的生物墙。这种生物培采用了一种空心砖瓦,填充了树胶、草籽右l施过肥的土壤,在砖瓦下接通水管。几个月后绿油油的嫩草便从里面长出来,十分美观,可以减少噪声和空气污染。 In some cities in Brazil, people have seen some green walls. The green grass on the walls runs through the wind like a green vertical ocean. This is Brazil’s unique biological wall. This kind of biological culture uses a kind of hollow brick, which is filled with soil where the gum and grass seeds are applied to the right, and connects the pipes under the tile. After a few months, the tender green grass grows out of the inside, which is very beautiful and can reduce noise and air pollution.
