someone once said that "the spring is very short, don't live up to this beautiful spring", but this sentence is not applicable on the spring equinox, because on the spring equinox, the day and night are as long as each other, which is very fair. During the spring equinox, customs vary all over the country, including eating wild vegetables, sending spring cattle, erecting eggs, etc.

equinox is one of the solar terms reflecting the changes of the four seasons. In ancient China, the beginning of spring, summer, autumn and winter were used to express the beginning of the four seasons. The spring equinox, summer solstice, autumn equinox and winter solstice are in the middle of each season. On the spring equinox, the sun shines directly at the equator, and the day and night time around the earth are equal, so the ancient spring equinox and autumn equinox are also called "day and night equinox", and there is a folk proverb "spring equinox and autumn equinox, day and night equinox". After the spring equinox, winter crops in most parts of China enter the spring growth stage. There is a proverb in Central China that "the wheat rises at the spring equinox and is worth thousands of gold at a moment". The temperature in all parts of our province continues to rise, but generally it does not rise as fast as the period from rain to the spring equinox. In late March, the average temperature in the north of the basin is mostly 13 ℃ to 15 ℃, and in the south of the basin is mostly 15 ℃ to 16 ℃. Most parts of the plateau have melted and melted, and the average temperature in ten days is about 5 ℃ to 10 ℃. The highest temperature is in Jinsha River, Anning River and other river valleys in the southwest of our province, with an average temperature of about 18 ℃ to 20 ℃. In addition to the marginal mountainous areas in the basin, the average daily temperature rises steadily to more than 12 ℃ in seven or eight years, which is conducive to the sowing of rice, corn and other crops, and afforestation is also very suitable. However, there is often a strong cold air intrusion in the basin before and after the spring equinox, the temperature drops significantly, and the lowest air temperature can be below 5 ℃. Sometimes a small stream of cold air comes one after another, resulting in low temperature and rain for several days, which is unfavorable to agricultural production. According to this feature, we should make full use of the weather forecast, grasp the cold tail and warm head, and sow in time.spring equinox three times
