What is the truth of the old saying in the countryside that "the grain is neither hot nor cold"?

Thousands of years of farming culture has derived a lot of life wisdom, and rural proverbs and old sayings are one of them. It is a summary of people's experience and lessons in production and life, which is refined in concise language for future generations to refer to and learn from. Today, let's discuss the truth of this sentence: "It's neither cold nor hot, and the grain will not bear fruit".

It is often said that people eat whole grains, how can they not get sick? In ancient times, there were two main sayings of "five grains", one was rice, millet, millet, wheat and glutinous rice; The other is hemp, millet, millet, wheat and rice, and the difference lies in "rice" and "hemp". This is because the ancient civilization of China originated from the Yellow River valley, and rice was mainly produced in the south, and rice was rarely planted in the north, so there was no rice in the "five grains" behind it.

If there is no temperature difference between hot and cold weather, it will not be cold if it is cold, and it will not be hot if it is hot, then the crops will not grow and mature normally, the heading will not bear fruit, and it will not swell if it swells, resulting in reduced production or no harvest.

As we all know, the growth of crops not only needs sunlight, water and nutrients, but also temperature has a great influence on it. Agriculture depends on the weather. People plant different crops in different seasons according to the changes of seasons and the habits of various crops. For example, before and after Qingming, planting melons and beans; Rice and corn are sown in spring and harvested in autumn; Planting wheat in winter and harvesting in summer follow the laws of nature.

If it's winter, it won't be cold when it's cold, and pests and eggs in the field will spend the winter safely. In the next spring, it will multiply in large quantities, causing the breeding and spread of crop diseases and insect pests. If it is not well controlled, it will also affect the annual harvest. Moreover, because of high-temperature evaporation and dry weather, it will aggravate the drought, which is not conducive to the growth of crops in winter and spring sowing and spring ploughing, and it will also cause wheat to grow vigorously and reduce its cold resistance.

However, when spring should blossom and spring seeds should be sown, there will be a cold at the end of spring, and the crops sown in spring will stop growing due to frostbite or freezing. In summer, crops grow fastest because of high temperature, abundant sunshine and abundant rain. However, if it is not hot when it is hot, cloudy all day and the temperature is low, even if it is held in the snow for six consecutive years, it will not be conducive to the growth and heading of crops such as rice and corn, and of course it will not bear full grains.

Therefore, the old saying in rural areas, "neither cold nor hot, the grain will not bear fruit", fully embodies the wisdom and experience of the ancient working people and is scientific and reasonable. It tells people that only by respecting nature and understanding its laws can we effectively and reasonably use nature and create benefits for us.
