Rain, solar terms, snow and ice are busy

Rain is the second of the 24 solar terms. Every February 19, there are 24 solar terms of rain. At this time, the temperature rises, the snow melts and the precipitation increases, hence the name rain. The rain solar term generally starts from February 18 or 19 and ends on March 4 or 5. Rain, like Grain Rain, light snow and heavy snow, is a solar term reflecting precipitation.

Rain not only indicates the beginning and increase of rainfall, but also indicates the rise of temperature. It was cold before it rained. After the rain, people obviously feel that spring has returned to the earth, spring is blooming, spring is full, and people's breath is inspiring their body and mind.

With the arrival of rain and solar terms, snowflakes fall one after another, and the weather soaked in cold air slowly disappears, while the days of spring breeze, melting ice and snow, moist air, mild sunshine and drizzle are coming to us.

In spring, everything germinates and grows, and it begins to rain just when it is needed. People often say: "Spring blossoms, and rain is busy to send fertilizer." A year's plan lies in spring, how to see the spring rain. For farmers, rainwater is the key period for Koharu management and Da Chun preparation for farming, and it plays a very important role in the growth of crops. Our life is also full of new hopes.

After the rain, the temperature in most parts of China rose to above 0℃, the daily average temperature in Huanghuai Plain reached about 3℃, the average temperature in Jiangnan was about 5℃, the temperature in South China was above 10℃, and the average temperature in North China was still below 0℃. Before and after rainfall, rape and winter wheat will generally turn green and grow, which has a great demand for water.

"Spring rain is as expensive as oil", so suitable precipitation is particularly important for crop growth. However, the precipitation in North China, Northwest China and Huanghuai areas is usually less, which often cannot meet the agricultural consumption demand. If there is little rain in early spring, the best economic benefit can be obtained by timely spring irrigation before and after the rain.

In addition, the rainy season is one of the seasons with the most cold waves in the whole year. Say goodbye to snowflakes and cold soaking, and spring comes quietly step by step in the warm and cold. "Several early warblers compete for warm trees, and their Chun Yan pecks at new soil." In rainy season, farmers open windows and begin to welcome the swallows back. In the field, farmers began to control the cattle, and the new year's farming is in the process of brewing.

"Rain" refers to the phenomenon that the spring breeze gradually blows all over the earth, the ice and snow melt and flourish everywhere. People's perception of the weather and the adjustment of consumption life are both ways to realize the harmonious unity between man and nature and the pursuit of "harmony between man and nature". In short, the solar terms of rain play a vital role in the consumption life of agriculture, rural areas and farmers.
