Xu Mingguang started "The Encyclopedia of Agricultural Administration" one by one: "June: As the saying goes,' June is not hot, and the grain will not bear fruit'. "The old farmer said,' It rains in dog days. When it rains, sunny days are the most important, and sunny days are hot'."

This proverb is scientific because the growth of crops needs not only water and fertilizer, but also light and heat. Autumn crops, such as rice in the south and corn in the north, need higher accumulated temperature and more light during their growth. Besides, it's always hot in dog days. If it is hot, it will be hot, if it is cold, it will be cold, and if it rains, it will rain. This is the ideal weather for farmers, that is, good weather. If the dog days are abnormal, not only not hot, but cool, then at other times, it is likely that the climate will be abnormal, which is not conducive to agricultural production.
