This greenhouse’s cultural and geographical questions

Hello LZ.

This is a geographical problem. Because when doing it, you must pay full attention to the words "Gansu" and Linze area.

Gansu It is the only province in my country that crosses the north-south and east-west boundaries, but only Longnan City has a subtropical climate, and the rest of the places have a continental climate.

So the location mentioned in the title is a place within the Hexi Corridor, where the valley Interleave.

After understanding this, let’s examine this question...

There is a trap in question 6

Note that the question refers to "precipitation characteristics". rather than "precipitation"

If it is precipitation, of course you should choose C

But this question is about the characteristics of precipitation. Combining the chart of this question, we find that it rains after nightfall. Obviously, there will be rain in this place after nightfall. There is an updraft.

Combined with what we said before, the valleys here are intertwined, which means that valley winds are formed here. After nightfall, the temperature in the valleys is high and rises slowly. The temperatures on the slopes are low, and they travel down the slopes to the bottom of the valley, forming mountain breezes. , so the bottom of the valley with constant updrafts presents a regional small low pressure...

So question 6 should be selected as B

7 and 8 should be read together...

As the name suggests, a greenhouse must be related to temperature. It must have nothing to do with sunshine. It must have nothing to do with precipitation (after all, even in a fully enclosed environment, you can set up your own sprinkler facilities...)

When the greenhouse is closed, apart from the temperature, the only thing that can be thought of is ventilation!

The purpose of ventilation is to avoid the imbalance of gas distribution in the greenhouse, especially the roots that only perform respiration, which may It enriches the soil with carbon dioxide, dissolves in water to form carbonic acid, and increases the soil pH value.

The most suitable time for ventilation is, of course, from 18 o'clock at night, when the mountain wind blows. Just open the door towards the hillside.

So you should choose D for question 7 and C for question 8
