Is the date of the first frost twenty-four solar terms the time of the first frost?

The date of the first frost in the 24 solar terms is not the time of the first frost, which means that the weather is getting cold and first frost has begun.

The first frost is one of the 24 solar terms of the lunar calendar. Entering this solar term, the weather is getting colder and frosty. The first frost is usually around Gregorian calendar1October 23rd 10 every year. At this time, the first frost appeared in the Yellow River basin in China, and most areas were busy planting crops such as three wheat.

Extended data:

In the first frost, autumn harvest has been completed in most parts of the north. Even cold-resistant onions can't grow any longer, because "the first frost can't support onions, and the longer they grow, the more empty they are." In the south, it is the peak season of "Sanqiu". Only single-season hybrid rice and late rice are harvested, and early-season wheat and early-season rape are planted. Picking cotton, pulling cotton stalks, ploughing and soil preparation.

"The straw is pulled all over the floor, and there will be fewer insect pests and diseases in the future." Take back the straw and stubble in time after harvest, because there are many wintering eggs and germs hidden there. The Chinese cabbage in North China is about to be harvested, so it is necessary to strengthen the later management. In the first frost season, most parts of China have entered the dry season, so we should attach great importance to forest protection and fire prevention.
