What do you mean 19-year-old mango seed and 20-year-old plum blossom?

"Nineteen-year-old awn seed and twenty-year-old plum blossom" are two of the twenty-four traditional solar terms in China, namely, the ninth solar term "awn seed" from summer to the future and the 1 1 solar term "plum blossom" in Xia Hou, marking the arrival of high temperature season and rainy season in southern China respectively. The specific explanation is as follows:

1, Miscanthus: Miscanthus is the ninth solar term from summer to the future, which is about June 5 or 6 of the Gregorian calendar. In the awning season, the momentum has reached its peak, everything is thriving, grains are heading, and there are wheat, rice and corn. They have entered the high-speed growth period, and at this time, it is also a period of frequent pests and diseases. It is necessary to strengthen field management and timely prevent and control pests and diseases.

2. Entering Mei: Entering Mei is the solar term of 1 1 in Xia Hou, which is about June 2 1 or 22 of the Gregorian calendar. Entering plum blossom, the solar terms are gradually hot and humid, and the weather is rainy, and the southern region begins to enter the rainy season. At this time, attention should be paid to flood control and epidemic prevention, which is also a critical period for crops, and management measures such as drainage and fertilization need to be strengthened.
