What does it mean that Han Xiao starts at Meihualing?

The moral of crossing Meihualing at the beginning of the slight cold is: During the slight cold season, peanuts grow among the mountains and rocks, and bloom together with cold ling.

1 and slight cold introduction:

Slight cold is the last of the 24 solar terms. Fighting refers to ugliness; The solar meridian reaches 300; Celebrate every year around 65438+ 10 20th. Slight cold, like slight cold, is a solar term indicating the cold weather. During the slight cold solar term from March 9 to April 9, the cold wave frequently goes south, which is the coldest season in a year.

2. Meteorological changes of slight cold:

During the slight cold solar term, the atmospheric circulation is relatively stable, and the adjustment period of circulation is about 20 days. When this circulation is adjusted, there will often be a wide range of rain and snow weather and strong winds to cool down. When the east longitude is 80 degrees, the west is the long wave ridge, and East Asia is the coastal trough.

Under the influence of the northwest wind flow control and the constantly supplemented cold air, there will be sustained low temperature in China. In some parts of China, slight cold is not as good as slight cold, but in the southern coastal areas of China, the lowest temperature in the whole year appears in the slight cold solar terms.

Forming slight cold and farming activities;

1, the formation of slight cold:

After the winter solstice, the direct sunlight point will gradually move northward, but in the following period, the direct sunlight point will always be in the southern hemisphere, and the heat in the northern hemisphere will always be lost, and the heat absorbed during the day is still less than the heat released at night. Therefore, after the winter solstice, the temperature in the northern hemisphere will continue to decrease, and the temperature will be the lowest during the slight cold solar term.

2, slight cold farming activities:

In the slight cold season, it is necessary to master the change law of cold and warm in agricultural production, and plant crops reasonably according to different years, different geographical locations and topographic conditions to avoid unnecessary losses. In the northern region, the fields were covered with snow and ice during this period, and there was no farm work. The fields in the south are not frozen and can be used for agricultural activities.

Due to the large geographical span between north and south of China, different regions will have different production and cultivation for the same slight cold solar terms. In winter, the northern region is covered with snow, so it is almost impossible to grow crops.

In most areas, there is not much farm work in the fields, and all of them have winter holidays. Slight cold is the period with the least rain in a year. The southern region should pay attention to applying winter fertilizer to wheat, rape and other crops, and do a good job in cold and antifreeze and water conservancy construction.
