Is it the vernal equinox or the intense heat that is the fastest growing period of warm crops?

Summer solar term is the hottest period in a year, and it is also the fastest growing period of warm-loving crops, just before and after the "dog days" solar term. At this time, it is also in the same season of rain and heat, and the rainfall is obviously higher than other months.

Therefore, during this period, farmers should always pay attention to the attack of heavy rain, prevent the occurrence of floods, and do a good job in field preparations for drought resistance and moisture conservation.

Weather and climate in hot summer

During the summer heat, most parts of China entered the hottest period of the year. Except for the Qinghai-Tibet Plateau and Northeast China, the weather is hot in most areas, with high temperature of 35℃ common, and high temperature of 40℃ often appears, with little temperature difference across the country.

The high temperature during the hot summer is a normal climate phenomenon. At this time, if the light is insufficient, the growth of warm crops such as rice and cotton will be affected. However, the continuous high temperature weather for a long time is very unfavorable to the growth of crops such as rice. There is an agricultural proverb in the middle and lower reaches of the Yangtze River: "It is a bit dry if it doesn't rain for five days, a bit dry if it doesn't rain for ten days, and it doesn't rain in January."
