8,000 plots on both sides of the To Lich river, Hanoi, are being depleted by dozens of workers with bamboo deciduous grass.
Dozens of employees at the Hanoi Drainage Company are planting bamboo leaves on both sides of the Toich River to replace the old weed.
The type of soil used for growing grass is a fertile soil, rich in nutrients that helps grow on the grass.
According to a representative of the Hanoi sewage company, planting grasses began in the last 9.7 days.
The employees had previously cleaned the weed layer. "Many days before planting we cleaned the weeds on the plots on the embankment. When we finish planting grasses along the river embankment, we will irrigate and use the plants to grow well. " – said Nguyen Duc Hung, head of Garbage Group 1 (Hanoi Drainage One Member Co., Ltd.).
Bamboo leaf grass quickly adapts to the environment, grows quickly, but does not grow at a high level. It is a good choice for replacing weeds on both sides of the river, which causes aesthetics.
Leaves of grass grow to maturity, with hairs at the border, about 1.2 cm wide and 5-7 cm long.
To grow new grass, workers will have to remove the old grass and then the porous soil to plant the bamboo leaves.
Over the years, Hanoi has found many solutions to "save" the Toich River from pollution, but it has not yet yielded results. The pilot project on the purification of rivers using the Japanese Nano-Bioreactor technology is now expected to make the river sleepy.
