What's the best weather for poplars?

Poplar prefers sunshine to shade. Cold-resistant, no frostbite at MINUS 40 degrees. The climate is drought-tolerant, but not hot and humid, and the southern cultivation is prone to pests and diseases, and the trunk is often shrub-like. Weak alkaline soil, soil with salt content below 0.4%, grows poorly in cohesive soil. Deep roots, developed roots, strong soil-fixing ability and strong tillering ability. Strong wind resistance and pest resistance. The service life is over 90 years. It is the most common tree in northwest China. As long as there is grass, there is the shadow of poplar. Poplar is not very particular about living conditions. Roadside, beside the ridge, where there is loess, there is its survival. It doesn't chase rain, and it doesn't long for sunshine. As long as you can give some water to the hardened land, a branch of poplar will take root and sprout. As long as you move a little space for weeds to survive, it will decorate the yellow land and hold up a piece of green. It doesn't need artificial fertilization or watering like a delicate lawn. As long as you don't chop with knives and axes, give it a relaxed environment and let it absorb free air, it will stand upright and never say no to the land where it grows. It's not a branch, it's rooted in poor soil, and it's happy-go-lucky, otherwise, it belongs to grassroots. Although poplar was born in poverty, it is the most concerned about the quality of life. There is still ice in the soil, and the spring breeze is still chilly. Its branches have sprouted green shoots. Under heavy pressure, every bud and leaf of it is forging ahead, never bending down to beg, and there is no flattering face. In the autumn wind, although the leaves have been stripped, the thin branches are still full of essence, and the branches stand upright and hold their heads high. In the severe winter, it still stands on the cold yellow land, facing the sword, frost and snow. The branches are proud, the trees are silent and the trees are noisy.
