立春立春是二十四节气中的第一个节气,在公历的2月3、4或5日。立春中的“立”是开始的意思。立春节气过后,气温逐渐回升,万物复苏。在我国古代,人们把每个节气又分成了三候。因为通常是五天一候,所以一年有七十二候,每候又有一个对应的物候现象。物候现象反映了动植物和自然界的变化。由于古代的科学技术水平有限,再加上每年受天气等因素的影响,使得有些时候的实际情况和古人总结的物候现象不一致,这时,我们就应该科学、灵活地去看待了。
Spring is the beginning of spring twenty-four solar terms in the first solar terms, in the Gregorian calendar in February 3,4 or 5 days. In the beginning of spring “立 ” is the beginning of the meaning. After the Spring Festival solar term, the temperature gradually picked up and everything recovered. In ancient China, people put each solar terms into three. As it usually takes five days, there are seventy-one seasons a year, with a corresponding phenological phenomenon at each waiting time. Phenology reflects the changes in flora and fauna and nature. Due to the limited level of science and technology in ancient times and the influence of the weather and other factors each year, the actual situation in some cases is inconsistent with the phenomenal phenomenon summarized by the ancients. At this time, we should treat it scientifically and flexibly.
