8,000 plots on both sides of the river to Lich, Hanoi, are exhausted by dozens of workers with bamboo leaves.
Dozens of workers at the Hanoi Drainage Company are planting bamboo leaves on both sides of the To Lich River to replace the former grass.
The type of soil used to grow grass is a fertile soil rich in nutrients that helps the grass grow enough to grow.
According to a representative of the Hanoi sewer company, grass planting began in the past 9.7 days.
Workers clean the weed layer earlier. "Many days before planting we cleaned the weeds in the land plots of the embankment. When we finish planting the grass along the coast, we will irrigate and fertilize the tree to grow well. – Mr Nguyen Duc Hung, Head of Garbage Group 1 (Hanoi Drainage One Member Co., Ltd.) said.
Bamboo leaves have a rapid adaptation to the environment, rapidly growing but not growing. This is a good choice for replacing weeds that are overgrown on both sides of the river, causing aesthetics.
Leaves of grass after maturity grow in chess, with hair on the border, about 1.2 cm wide and 5-7 cm long.
To grow new grasses, workers will have to remove the old grass and then the porous soil to plant bamboo leaves.
Over the years, Hanoi has found many solutions to "rescue" the To Lich River from pollution, but has not yet delivered results. At the moment, the Nano-Bioreactor Japanese River Renewal Pilot Project is expected to overturn the river visually.
