What does the old saying "cloudy in summer, gold everywhere" mean?

Summer is the twelfth solar term in a year and the last solar term in summer. The so-called big heat refers to the hottest time of the year.

Summer? It means hot. It's extremely hot in summer. Compared with the heat, when will the heat come? Hot and humid steaming? When you reach the extreme.

High temperature, extreme heat, frequent thunderstorms and typhoons are all prominent features of the arrival of the summer solar term. The summer heat of 2020 will come on July 22nd.

At that time, the temperature will suddenly rise above 30℃, and the highest temperature can even reach 38-40℃. Everyone must do a good job of heatstroke prevention in advance to avoid heatstroke due to overheating.

Rural proverb

It's cloudy on a hot day, arachis duranensis?

What do you mean? The summer heat is coming, let's take a look. It is said that it is always rainy after the arrival of the summer solar term, which can effectively alleviate the drought caused by high temperature days.

Under this premise, crops can thrive, especially rice that needs rain irrigation, and there will be a good harvest in autumn.

In fact, in some arid places, whenever the summer heat comes, there will be drought. If it rains heavily at this time, it can effectively solve the drinking water problem of crops and livestock and poultry.

If you can understand the meaning of these two common sayings, I believe you can appreciate people's thirst for rain in summer.

First, it's hot and cloudy in arachis duranensis.

Popular words in different regions have different regional characteristics. People living in the middle and lower reaches of the Yangtze River summed it up according to what they have seen and heard in their lives and climate change? It's cloudy on a hot day, arachis duranensis? It's actually a description of real life.

The meaning of this proverb is very clear, that is, if there is rainy weather in summer, it will be very helpful for crop growth. I believe everyone has heard of the saying that spring rain is as expensive as oil. In fact, the temperature is extremely high after the arrival of the great summer heat.

Therefore, in this high temperature weather, crops, livestock and human beings will be particularly affected. Especially in summer, it is usually there. Dog days? Appears before and after middling.

This year's dog days start from July 16 and are expected to end on August 24th, about 40 days before and after.

This year's summer heat appeared on July 22, the seventh day of the first crouching. So from this perspective, the weather has been particularly hot this year.

Especially in summer, the high temperature is in the early stage, indicating that the high temperature weather comes very early.

Under this premise, drought is easy to occur, so it often rains in dog days, which is the main way to alleviate the drought.

The growth of crops can not be separated from the irrigation of rain, especially when the summer heat and dog days come, which is the critical period of crops.

Among many crops, except rice, which needs water especially, in fact, other crops are also afraid of drought. At this time, it is even more necessary to be nourished by rain.

Many proverbs, Rainy days, abundant grain and cotton. ; ? No drought in dog days, one acre plus one load? ; ? It's raining in Foley, hoarding Ridomi? And so on, all illustrate the importance of rainy days to grain harvest.

Therefore, if it rains continuously in summer, it is really more precious than gold.

Second, the heat is in the dog days, with less rain and more disasters.

I believe everyone has heard of it, right? Trivolt fever? As the saying goes, it will be the hottest season of the year because the temperature is very high in dog days and the summer solar term is coming.

If there is particularly little rain in this critical period, it is prone to summer drought. So from this perspective? Cloudy on a hot day? In other words, rainfall is especially precious at this time of year.

According to scientific theory, the temperature is relatively high during the hot summer, which is actually beneficial to the growth of crops.

However, if there is persistent high temperature and little rain, it will definitely affect the growth of crops. Because crops can't grow without the nourishment of boiling water.

What's important is that high temperature weather can easily take away the water of crops and easily lead to the death of crops from crying. At the same time, even if the crop is not dead, it will affect heading and pollination.

If the temperature is too high, crops will suffer, so the most intuitive effect is to reduce production.

Of course, due to the gradual improvement of agricultural level in modern society, several wells have been drilled in many places. In this way, even if the temperature is too high and leads to drought, artificial watering can be used to alleviate the disaster.

But we should also realize that if we only rely on pumping irrigation, it will also have adverse effects on crops.

conclusion

It's cloudy on a hot day, arachis duranensis? It is not only the common people's thorough understanding of nature, but also a proverb about agricultural production.

It is very hot in summer, and if there is little precipitation, it will lead to serious drought. This proverb is also a proof of reality. Only when it rains constantly in summer can we harvest more food in time.
