Online examination paper single choice question 32. [2 points] Mango is the busiest solar term for farmers in a year.

Introduction of mango varieties:

Ear seed is the ninth solar term in the twenty-four solar terms, the third solar term in summer and the beginning of noon month in the trunk calendar. The yellow meridian of the sun reaches 75 degrees, which is celebrated on June 5-7 of the Gregorian calendar every year.

"awn seed" means "grain crops with awns can be planted, and they will become invalid after planting" This season, the temperature rises obviously, the rainfall is abundant and the air humidity is high, which is suitable for planting cereal crops such as late rice. Agricultural planting is bounded by the solar term "awn seed", and the survival rate of planting has become lower and lower since then. It is the reflection of ancient farming culture in festivals.

The solar term of awn species is of great significance in agriculture. The book of the lunar calendar says, "The bucket refers to the awn seed. At this time, there are awn valleys to plant, and after that, it will be invalid, hence the name." This means that the solar term of canopy is suitable for planting grain crops with canopy; It is also the dividing point of the timing of planting crops, and it will be invalid after that.

The folk proverb "It's no use planting awns again" tells this truth. Mango is a solar term for busy farming, which is also called "busy planting" by the people. This season is the time to plant rice in the south and harvest wheat in the north.

Historical origin:

Miscanthus species, "Miscanthus" refers to some crops with awns, such as rice, millet and millet; And "seed" refers to "seed" and "seed" for sowing. The name "awn seed" means "awned food crops can be planted, and then they will become invalid." There is a folk saying, "If you don't plant awns, it's useless to plant them again."

This is a fact. It is a summary of agricultural time and season by ancient farming culture, which shows that the solar term of awn seed is the dividing point of planting crops. In the awning season, the temperature rises obviously, the rainfall is abundant, and the air humidity is high, which is suitable for planting cereal crops such as late rice.

This solar term is the dividing point of agricultural time. Because of the hot weather, it has entered a typical summer, and farming sowing is bounded by this season. After this solar term, the survival rate of crops is getting lower and lower. Ear planting is the season for planting cereal crops, and late rice should be planted at this time. In southern rice areas, "awn seed" is the peak season for transplanting rice.

The northern region is dryland agriculture, and wheat is the main food crop. This season is the harvest season of the northern summer crop wheat. The arrival of "Mangzi" marks another round of busy farming. People in the south are busy transplanting rice seedlings and harvesting wheat in the north.
