Moisturize things silently in good rain season (24 solar terms · rain)

  "The drizzle in Tianjie is as moist as crispy, and the color of grass is far away, but there is none." The drizzle in early spring will always bring green and hazy memories.

The arrival of "rain" is a forewarning.

  Rain is the second solar term in the twenty-four solar terms. At this time, the sun reaches 330 degrees of ecliptic longitude, which is the season of "seven-nine rivers open and eight-nine wild geese come" in "Number Nine".

The rainwater solar term usually comes from February 18 to 20 in the Gregorian calendar, and this year's rain falls on February 19.

Like Grain Rain, Light Snow, and Heavy Snow, rain is also a solar term that reflects the phenomenon of precipitation.

  The east wind thaws and turns into rain

  Temperatures rise above 0 degrees Celsius in most areas

  In "The Seventy-two Hours of the Moon Order", it says: "In the middle of the first month. When the sky is full of water, the beginning of spring belongs to wood. However, those who produce wood must also be water. Therefore, rain follows the beginning of spring, and when the east wind is thawed, it will disperse and become rain. That's it." That is to say, spring is inseparable from the moisturizing of water. Before and after the rainy season, the grass and trees sprout, the snow gradually decreases, the rain gradually increases, and spring is here.

  The ancients divided the 15 days of the rainy solar term into three phases: the first phase of offering sacrifices to otters; the second phase of the geese north; the third phase of the sprouting of vegetation.

It means that when the otters start fishing, they put the fish they catch on the shore first, just like displaying offerings for sacrifice; after 5 days, the geese fly back from the south to the north one after another; In the silent spring rain, the grass and trees stretch out and grow.

During the rainy season, the temperature in most areas returns to above 0 degrees Celsius, the average temperature in the Huanghuai Plain has reached about 3 degrees Celsius, the average temperature in Jiangnan is about 5 degrees Celsius, and the average temperature in South China is above 10 degrees Celsius.

  With the arrival of the rainy solar term, the weather with snowflakes flying and cold air gradually disappearing, moist air, mild sunshine and drizzle days are coming to people - "Thousands of eagles sing green and red, Shuicun Mountain Guojiuqi winds ".

The "second movement" of spring has been played, and the breath of spring is getting stronger and stronger.

  rain, rain, crops are good

  Winter wheat and rape have generally turned green, entering the best spring irrigation period

  "Spring rain is as expensive as oil." Before and after the rain, winter wheat and rapeseed generally turn green, which requires a large amount of water. Appropriate rainfall is very important for the growth of crops.

  "Rain and rain are good for crops, and a big spring and a small spring are a treasure." For agricultural affairs, the rainy season is a critical period for management in small spring and preparation for cultivation in big spring.

In North China, Northwest my country and the Huanghuai region, the precipitation is generally less, which often cannot meet the needs of agricultural production.

If there is a lack of precipitation in early spring, spring irrigation should be carried out in time to replenish water before and after the rain.

Spring irrigation promotes early spring irrigation, which is conducive to early relief of drought and meets the demand for water and fertilizer when winter wheat and rapeseed turn green.

  In the area south of the Huai River, cultivating and hoeing is the main method, and at the same time, the fields are cleaned and drained to prevent excessive spring rains, which will cause dampness and rotten roots.

In South China, the double-season early rice seedlings have already started, and attention should be paid to grasping the "cold tail and warm head", rushing to plant the seeds, and striving to sow all the seedlings at once.

  In addition, the rainy season is when there are many cold waves throughout the year, and the weather is hot and cold, which is extremely harmful to crops that have sprouted or turned green. Always pay attention to the cold and frost protection of crops.

  It's hard to breathe from warm to cold

  Cold wave strikes, spring cover is the key to prevent cold

  After the rain, the sunshine duration and intensity in the northern hemisphere are increasing, and the temperature rises quickly, but the cold air does not retreat a thousand miles.

It frequently competes with the active warm and humid air flow, and it turns warm and cold.

Changes in temperature can easily lead to respiratory diseases such as colds and fever, and a sudden drop in temperature will also make the elderly more uncomfortable, and it is even more unfavorable for patients with high blood pressure, heart disease and asthma.

During this period, you should still pay attention to keeping warm and be prepared for the surprise attack of "falling spring cold".

  With the arrival of spring, the temperature rises, the capillaries and pores of the human skin gradually open, the blood circulation is accelerated, and the blood supply to the brain is relatively reduced. In addition, the changes in the length of day and night and the comfortable surrounding temperature will make people sleepy and drowsy. sleep.

During the rainy season, if you want to overcome the spring hardship, you must arrange your work and rest reasonably and participate in outdoor exercise in moderation.

  In addition, traditional Chinese medicine believes that the liver controls the growth of hair, and the liver fire is prosperous in spring, which is easy to damage the spleen. On weekdays, attention should be paid to regulating liver qi inside and clearing damp pathogens outside to benefit the spleen.

The three meals should keep the five flavors unbiased, eat less spicy, raw and cold, avoid overeating, and should eat more yam, lily, carrot, bean sprouts and other foods that strengthen the spleen and stomach, as well as fresh fruits and vegetables.
