Things to note when doing agricultural activities during the Bailu period

During the White Dew solar term, cold air becomes increasingly active, and low temperatures often occur in autumn, affecting the heading and flowering of late rice. Therefore, it is necessary to prevent low temperature damage and diseases and insect pests. When cold air invades, you can use watering to keep warm. Watering more than two inches before the temperature drops can increase the temperature by 1~2℃. When the temperature drops, you can drain shallow water during the day and fill it at night on sunny days; on rainy days, you need to fill it with thick water.
During the White Dew period, the weather should generally be dry and wet, with wet being the main weather condition. During this solar term, the heat gradually dissipates, the weather becomes clear and crisp, the dew drops are cool, and the sweet osmanthus is fragrant. It is the golden season for tourism. "Bai Lu" is the transition point between summer and autumn, and the daily temperature varies greatly. "Don't expose your body during Bai Lu", so the old, weak and sick people should pay more attention to adding or removing clothes in time to prevent catching cold.
It is recommended that everyone needs to fully understand the climate characteristics of Bailu and take corresponding agricultural measures to reduce or avoid the harm of autumn rain. On the other hand, we should also take advantage of the rain to store water, especially in eastern South China, where Bailu is another solar term with heavy rainfall after Grain Full and Summer Solstice, so we should not miss the good opportunity.

What impact does Bailu have on farming?

1. The average temperature during the White Dew period in South China is about 3°C ​​lower than that during the End of Heat period. In most areas, the average temperature drops below 22°C. According to the climatological standard of dividing the four seasons, autumn begins. Autumn rains in South China mostly occur from White Dew to before Frost Descent, with the most occurring in the middle and lower reaches of the Minjiang River and Qingyi River, and relatively less in central South China.
2. There is also a folk proverb that "if there is too much White Dew, the road will be rainy every day." Although it is not possible to make a weather forecast based on whether it will rain on the day of White Dew, there is usually a period of continuous rainy weather before and after the White Dew Festival. Moreover, since then, rainfall in South China has been characterized by low intensity, many rainy days, and often continuous rainfall. Correspondingly, the sunshine during the White Dew in South China drops by about half compared to the End of Heat, and the decreasing trend continues until winter.
3. The White Dew solar term is unfavorable for the heading and flowering of late rice and the bursting of cotton bolls. It also affects the harvesting and drying of mid-season rice. Therefore, there is a saying in the agricultural proverb that "the weather is clear during the White Dew solar term, and the rice is as white as silver." Only by fully understanding the climate characteristics of Bailu and taking corresponding agricultural measures can we reduce or avoid the harm of autumn rain. On the other hand, we should also take advantage of the rain to store water, especially in eastern South China, where Bailu is another solar term with heavy rainfall after Grain Full and Summer Solstice, so we should not miss the good opportunity.
