As the saying goes, Ant Manor is not hot in summer.

As the saying goes, Ant Manor is introduced as follows:

Little knowledge: As the saying goes, "Summer is not hot, and grains are not bulging", which means that the summer temperature and rainfall are not enough, and the grain harvest will be affected!

Summer is the twelfth solar term among the twenty-four solar terms and the last solar term in summer. Climate characteristics: high temperature and summer heat, frequent thunderstorms and typhoons. As the saying goes, "The summer is not summer, and the grains are not bulging", which means that if the temperature is too low and the rainfall is insufficient during the summer, it will have an adverse impact on the grain harvest. Because midsummer is the key period of grain growth, and high-temperature and sufficient sunshine can promote the growth and development of grain, while appropriate long-term rainfall is beneficial to grain irrigation and root absorption of nutrients.

If the solar term temperature and rainfall are not enough, it will affect the grain harvest. This is because the growth of crops needs certain climatic conditions. If the climatic conditions are insufficient, the growth of crops will be limited, thus affecting the quality and yield of food. The fruit will become not full or even dry, which will seriously affect the grain harvest. We know that there are two necessary conditions for the growth of crops, namely water and heat. Moisture should be moderate, not too much or too little.

The heat required by crops mainly comes from light. Only when the light is sufficient, plants can carry out photosynthesis, and then synthesize organic matter to make the seeds of crops fat. In the same period of summer rain and heat in China, for crops, sufficient heat in summer can consume too much rain, and rain can also offset too much heat. During the summer heat, spring wheat was planted to the north of the Great Wall in China and harvested in August and September.

The "summer heat" of the great summer heat plays an important role in whether the single-season rice planted in the northeast and the double-season rice planted in the south can have a good harvest. There are also many proverbs corresponding to "summer is not hot, and grains are not bulging", such as "summer is not hot, grains are not fruitful" and "June is not hot, grains are not fruitful." And so on, all reflect the important role of summer in China's agricultural planting.

Therefore, farmers often expect the high temperature in summer to be "in place" to ensure a bumper harvest.
