What are the living environments and conditions for the poplars?

I'm in 5th grade, and we've learned that poplar trees have always been so straight. Wherever it is needed, it quickly takes root and grows thick branches. No matter whether it encounters a drought or a flood, it is always so straight, so strong, not weak, and not wavering.

So the aspen can survive anywhere. The following is the text (original):

Outside the car window is the vast Gobi, with no mountains, no water, and no people. The boundary between heaven and earth is not so clear, they are all muddy and yellow.

Where can you tell the train is moving?

That's a line of poplar trees along the railway line. Every few seconds, a tall and slender figure flashed out the window.

A traveler was looking at these guards on the Gobi Desert in fascination.

Daddy," the older kid shook his legs, "look how tall that tree is!" Dad didn't look back from his contemplation, but the sister next to him interjected:

No, that's not a tree, that's a big umbrella. ”

How can there be such a big umbrella! ”

Look how straight it is! My sister argued.

It's a tree, not an umbrella! My brother affirmed.

A small argument interrupted Dad's train of thought, and he smiled, slowly stroked the children's heads, and said:

It's not an umbrella, it's an aspen tree. ”

The elder brother is still not satisfied: "Why is it so straight and grows so big?" ”

Daddy's smile vanished, and his face turned serious. He thought for a moment, then said to his son and youngest daughter, "The poplar tree has always been so straight.

Wherever it is needed, it quickly takes root and grows thick branches. No matter whether it encounters a drought or a flood, it is always so straight, so strong, not weak, and not wavering. ”

Did dad just introduce the kids to poplar trees? No, he is also confessing his heart. And this, the children still can't understand.

They only know that their father works in Xinjiang, and their mother also works in Xinjiang. All they know is that their father has come back to their grandmother's house and taken them to Xinjiang to go to primary school, and then to middle school in the future. They only know that Xinjiang is a far, far place, and it takes a few days to take a train and a few days to take a car.

Now, the children have a little more knowledge. On the road to Xinjiang, there are many poplar trees. They are needed here, and they are here to take root.

Dad put a child in his arm and looked out the window at the poplar trees that flashed by, and fell into deep thought again. Suddenly, a smile appeared on his lips, because he saw a few small trees growing in the wind and sand on the right side of the direction of the train, beside a tall poplar tree.

It's dry, preferably in a desert area, and there are a lot of poplars on the other side of the Gobi Desert, and it's very vibrant.

Poplar is a strong plant, and even if you dig three feet into the ground and dig out all its roots, it will still grow. String aspen does not need to be watered, as long as you give it a right to live, it is enough.
