When beginning of spring first arrived, it was still cold and the temperature difference between day and night was large. Beginning of spring means coming, and then there may be a cold spring, which is also relatively cold. In 2023, because of the appearance of leap February, it will be cold for about two months before the weather will pick up.
Characteristics of beginning of spring
Beginning of spring is a solar term reflecting seasons and phenology, which means that the spring of everything's recovery has begun, the weather will gradually get warmer, and the vast land will present a vibrant scene. As the saying goes: "Spring hits five Kyubi no Youko, and spring hits six or nine heads." In other words, the days of beginning of spring are not in Kyubi no Youko, but in Liujiutou. After beginning of spring, the days became longer, the temperature rose slowly, the soil began to thaw from the lower layer, and the frozen soil became shallower.
On this day, people will obviously feel that the days are getting longer, the sun is getting warmer, and the temperature, sunshine and rainfall are also at the turning point of the year, tending to rise or increase. The growth of spring-sown crops in the field will be accelerated, and the water consumption at the jointing stage of rape and wheat will increase obviously. Pay attention to timely watering and topdressing to promote crop growth.
As the saying goes, "When it starts to rain in spring, get up early and go to bed late", which means that Da Chun will be ready for agriculture, and people can no longer idle their land. However, although it is spring, most parts of South China are still very cold, and it is still a scene of "snow is too late for spring, so it is flying among trees". Moreover, during this period, there will be a strong cold wave, which will cause the weather to dry ahead of schedule, often accompanied by strong winds and rainfall. For agriculture, we should pay attention to taking measures.
