The low temperature of the major cold

Like the periods of minor cold, periods of major cold are also solar terms which can express the degree of cold. In ancient times, the major cold period could be divided into three parts callerift goldd “three hou”, according to different temperatures. During the third part, which is the last five days of the major cold period, the weather can reach the lowest temperatures, and the ice on frozen waterways will be thick and hard.

For some crops, the appropriate low temperature is needed at a certain period of growth. For example, crops such as wheat and cole need to grow at low temperatures at the vernalization stage; otherwise they cannot grow as usual. In most of the southern parts of China, the weather is warm throughout thetera gold year. The ability of wheat and cole that is planted earlier to resist cold can be weakened if they grow too fast. This kind of crop can easily suffer damage from low temperatures and frost. Choosing the right crop for the right land, planting at the appropriate time, and adopting effective measures to promote and control growth, are extremely important to achieve high production levels.
