Should we plant melon beans around Tomb-Sweeping Day or around Grain Rain?

It is an agricultural proverb to plant melons and beans before and after Tomb-Sweeping Day. Tomb-Sweeping Day is closely related to agricultural production. As soon as Qingming arrives, the temperature rises and the rainfall increases, which is a good time for spring ploughing and sowing. Therefore, there is an agricultural proverb that "before and after Qingming, point melons and plant beans" and "planting trees is not as good as Qingming".

During the Qingming period, the average daily temperature in most parts of China has risen to above 12℃ except the northeast and northwest regions. From north to south to the inside and outside of the Great Wall, there is a busy scene of spring ploughing everywhere.

"In the Qingming period, the wheat grows in the third section." Wheat in the southern part of Huanghuai is about to start heading, rape has blossomed, and wheat in the northeast and northwest regions has also entered the jointing stage. In the later stage, we should pay close attention to fertilizer and water management and pest control. Dry farming in the north, early and middle rice in the south of the Yangtze River is in a suitable season for mass sowing, so we should seize the opportunity, seize the sunny day and sow early.

Extended data:

"It rains in succession during the Qingming Festival" is the climate characteristic of Jiangnan. At this time, it is often cloudy and sunny, and abundant water can generally meet the needs of crop growth. What is annoying and can't be ignored is the harm of wet stains and insufficient light caused by too much rain.

However, in the vast area north of the Huanghuai Plain, there is still little precipitation during the Qingming period. Water is often in short supply for crops and spring sowing. At this time, rain is very precious. These areas should do a good job in spring irrigation while storing water and preserving soil moisture to prevent the threat of spring drought.

Tomb-Sweeping Day is also often used as an indicator of weather and climate.
