Diary: Please observe the weather characteristics, plant characteristics, crop value and weather changes you feel in beginning of spring on that day, and then write it down.

Speaking of beginning of spring, people obviously feel that the days are getting longer and the sun is getting warmer. Temperature, sunshine and rainfall are often at the turning point of the year and tend to rise or increase. The growth of crops in early spring is accelerated, and the water consumption for bolting rape and jointing wheat is increased. Irrigation and topdressing should be done in time to promote growth. Agricultural proverbs remind people that "it rains in early spring, get up early and go to bed late", and Da Chun has also begun to prepare for agriculture. Although it is spring, most parts of South China are still very cold. "Spring snow comes too late, so it is flying through the Woods." These climatic characteristics should be taken into account when arranging agricultural production.

In ancient China, the fifteen days in beginning of spring were divided into three periods: "The east wind thawed, the insects began to vibrate, and the fish began to get cold", which meant that the east wind warmed and the earth began to thaw. Five days after the spring, the stinging insects slowly woke up in the cave. Five days later, the ice in the river began to melt and the fish began to swim on the water. At this time, there are still broken borneol on the water, floating on the water like fish.

Keeping in good health in spring should conform to the characteristics of spring sun spirit, and everything begins to grow. Pay attention to protecting the sun, focusing on the word "health". According to the nature, spring belongs to wood, corresponding to liver. This is the theory of five elements, which explains the physiological characteristics of five internal organs with the characteristics of five elements. For example, the liver likes regulating qi, has the function of relieving qi, and has no characteristics of hair growth, so the liver belongs to "wood". The physiological characteristics of the liver, which governs qi, anger and depression, are conducive to regulating qi. In the aspect of mental health in spring, we should try to avoid rage and depression, be open-minded and optimistic, and maintain a good attitude. At the same time, we should make full use of and cherish the "old" spring of nature, make use of the rise of yang, the appearance of everything and the vigorous metabolism of human body, and make the qi of Yang can be announced in spring and the metabolic function can operate normally through proper adjustment.

Spring Festival is usually after beginning of spring, that is, spring, so it is called Spring Festival. In this festival, people celebrate together, and the whole country celebrates together!
