What is the moral and connotation of the vernal equinox?

The moral and connotation of the vernal equinox is that day and night are almost equal. The vernal equinox symbolizes that the weather is no longer cold and everything is about to recover one after another.

The vernal equinox is one of the solar terms reflecting the changes of the four seasons, and it is also the fourth of the 24 solar terms. In ancient China, beginning of spring, Changxia, beginning of autumn and beginning of winter were used to indicate the beginning of the four seasons. The vernal equinox, summer solstice, autumn equinox and winter solstice are in the middle of each season.

On the vernal equinox, the sun shines directly on the equator, and the time between day and night is equal all over the earth. Therefore, the ancient vernal equinox and autumnal equinox are also called "equinox", and there is a folk proverb that "vernal equinox and autumnal equinox are equally divided day and night".

Busy with spring ploughing

In the northern areas with little rain in spring, we should pay close attention to spring irrigation, water saving and jointing fertilization, and pay attention to preventing late frost and freezing injury; South China still needs to continue to do a good job in drainage and flood prevention.

Early rice seedling raising in Jiangnan and Jianghuai areas has started, and the weather changes frequently in early spring. Attention should be paid to soaking seeds to accelerate germination when cold air comes, and sowing in sunny days when cold air ends.

The experience of the masses says, "A cold tail warms the head, so there is no need to worry about seedlings." According to the weather situation, we should strive for 3~5 sunny days after sowing to ensure that all seedlings are sown at one time. Spring tea has begun to sprout, so it is necessary to apply quick-acting fertilizer to control pests and diseases in time and strive for high yield and high quality tea.
