What do you mean, neither too hot nor too long?

Summer is coming, and crops grow rapidly at a certain temperature. If the temperature is high, the temperature is not enough, and the solar terms are not up, they will gradually mature. The proverb "neither too hot nor too long, neither too hot nor too hot" appeared in the lesson "Growing in Summer" published by the People's Education Publishing House of the sixth grade of primary school.

Everything needs to grow in summer, and summer is a growing season. Although it is very hot in summer, all plants will try to grow up in this season. If they don't grow in this season, all the crops will have a good harvest in autumn.

It is common sense that it is cold in winter and hot in summer, but there will be cases where it is not cold in winter and not hot in summer, which is an abnormal phenomenon. The growth of crops needs to be at a suitable temperature, and it also needs to meet the required accumulated temperature conditions, that is, the temperature difference between hot and cold can accumulate a certain temperature to bear fruit. Strange weather will definitely have an adverse effect on this year's grain output.

There are many similar sayings, such as "neither cold nor hot, the grain will not bear fruit", "the summer is not too hot, the grain will not bear fruit" and so on. At that time, all farmers' food depended on the weather, and the change of God's mood directly affected the harvest of farmers' friends. All these proverbs are the crystallization of the wisdom of farmers' friends.
