I learned a bachelor's degree and laughed at a group of cows. "

Extended data:

It is as expensive as oil because:

1, which is related to the season.

Spring is followed by autumn and winter. If there is little rainfall in autumn and winter, the soil moisture itself is not good, and it is often easy to form drought in winter and spring.

2. It is related to the large water demand of overwintering crops.

Spring is the period when overwintering crops, such as winter wheat, turn green to milk maturity, which requires a lot of water. Corn, cotton, etc. From sowing to emergence, we also need enough water, which makes the spring drought more prominent.

If there is rain at this time, it will naturally be particularly precious, so there is a saying that "spring rain is as expensive as oil".

3. It is related to the weather and climate characteristics in spring.

The temperature in northwest and north China rises rapidly in spring, and there are many windy days. Under sunlight, soil moisture evaporates strongly, leading to water loss.
