No solar terms in summer.

As the saying goes, summer is not hot, and grains are not bulging. That is to say, if the temperature and rainfall in summer are not enough, the answer is as follows:

In the old saying, "great summer heat" refers to the solar terms of great summer heat, and the following "no summer heat" refers to not being hot. If the weather is still not hot after entering the summer solar term, it will seriously weaken the growth of crops, reduce the quality and yield of crops, and make the fruits not full at all or even dry up.

Extended data:

If the temperature is not high in summer, it will affect the growth of crops, make them grow badly and lead to the decline of crop productivity. So people will observe the weather changes in summer to refer to the growth progress of crops.

Take preventive measures and manage in advance to ensure a bumper harvest of crops. Therefore, it is an important period for autumn crops to germinate after the big summer. Therefore, if the temperature of the weather is not reached, it will affect the sowing and rooting of plants, especially cereal plants, and rainy weather is the most taboo during flowering and pollination. Therefore, this rural proverb comes from the experience of the older generation and has some truth.

Due to the hot weather in summer, the temperature is very high. This season is between the dog days and the hottest time of the year. The hot weather in this period will also promote the growth of some crops.

This proverb also comes from the experience of temperature on crop growth in rural areas, which has certain reference value to rural agricultural production so far. Because the growth of crops needs sufficient sunshine, water and nutrients, which is the basic condition for high yield of crops. If one of these conditions is missing, the harvest may be affected.

During the hot summer, it is usually the season with the most sunshine and heat in southern China. This solar term is particularly beneficial to the double-cropping rice planted in southern China, and it is also an important period for the cultivation and growth of the previous crop and the next crop. Under the condition of sufficient sunshine in summer solar terms, crops in China can be harvested in August and September.

Because crops have just woken up from hibernation, they need sunshine at this time. If the weather is still cold and rainy, it will greatly affect the growth of crops. Therefore, this proverb in rural areas also reminds farmers to give corresponding management measures to crops in time according to weather changes, improve crop quality and promote high yield and harvest of crops.
