When is Grain Rain?

Twenty-four solar terms: in mid-March, after the rain, the earth's paste pulsates, and now it rains its valley in water. Rain is silent, just like the rain in my field. At this time, cover the grain and sow, from top to bottom. At this time, the weather is mild and the rainfall increases obviously, which has a great relationship with the growth and development of cereal crops. Appropriate rainfall is beneficial to the greening and jointing of overwintering crops and the sowing and emergence of spring sowing crops. In ancient times, the so-called rain gave birth to hundreds of valleys, which reflected the significance of modern agricultural climate in Grain Rain. However, too much rain or severe drought will often cause harm and affect the later yield. Grain Rain is in the middle and lower reaches of the Yellow River, which not only shows its agricultural significance, but also shows that spring rain is as expensive as oil. In ancient China, Grain Rain was divided into three stages: the first stage was when Ping was born; The second time, the cuckoo blows feathers; The third stage is from Dai Sheng to Sangzi. After Grain Rain, rainfall increased, duckweed began to grow, then cuckoo began to remind people to sow, and then Dai Sheng birds began to be seen on mulberry trees.

After the solar term in Grain Rain, the rainfall increased and the humidity in the air gradually increased. At this time, we should follow the changes of natural solar terms and take care of the climate characteristics. At the same time, due to the warmer weather, people's outdoor activities have increased, and peach blossoms and apricot blossoms have opened in the northern region; Catkin and catkins fly everywhere. Rain has bred hundreds of valleys. With sufficient and timely rainfall, cereal crops can thrive in Grain Rain season in southern China. In southern China, poplars fall, willows fall, cuckoos cry at night, peonies bloom and cherries are red. The natural scenery tells people that it is late spring. At this time, the temperature in the south rises rapidly. Generally, in late April, except for parts of northern and western South China, the average temperature has reached 20℃ to 22℃, which is more than 2℃ higher than that in mid-April. In the eastern part of South China, there is often a high temperature above 30 for a day or two, which makes people feel very hot. Low-altitude valley areas are used to enter summer. The climate characteristics of high temperature in south China in spring are beneficial to the early cropping cultivation measures in Da Chun. The suitable planting temperature of Polygonum cuspidatum is 65438 08℃ to 22℃, which can be satisfied at this time. The experience in the old arid areas in southern China has proved that planting Osmunda japonica early in Grain Rain can seal vine leaves before summer drought, enhance drought resistance and achieve high and stable yield.

Since ancient times, cotton farmers have regarded Grain Rain Festival as an indicator of cotton planting, compiled proverbs and passed them down from generation to generation.

Most of the weather proverbs in Grain Rain Festival revolve around the center of rain and no rain, such as gloomy in Grain Rain, rainy in summer, rainy in Grain Rain, and no dry soil for forty-five days. There are also solar terms in Grain Rain, such as high temperature and frequent rainy days, which will cause the occurrence and prevalence of pests and diseases of wheat. The vast rural areas should do a good job in the prevention and control of wheat diseases and insect pests according to the weather changes.

There are 24 solar terms in the summer calendar, and the sixth is Grain Rain Festival. What does Grain Rain mean? Why use it as a solar term name? To find out the reason, we have to start with the characterization in Cang Xie.

Since the existence of the world, human beings have gone through hundreds of thousands of years without words. In the era of the Yellow Emperor, an able man Cang Xie appeared in North Korea. He is determined to get rid of the suffering of the world without Chinese characters, quit his job, go out, travel around Kyushu and return to his hometown of Wu Yang Village. He lives alone in the ditch, and no one talks. It has been built for three years, and there are so many words in a bucket of rapeseed. The Jade Emperor was very moved and decided to reward Cang Xie. What is the prize? I won a gold medal. That night, Cang Xie was sleeping soundly when he suddenly heard someone calling him. Cang Xie, come and accept the prize. Cang Xie broke his eyes in a daze, only to see that the room was full of bright light. He didn't know why, so he quickly sat up and looked around. It doesn't matter at first sight, but I saw a golden man standing on the ground. He muttered: What's wrong with this? Where did you get this gold man? Is it a dream? Just thinking, the rooster in the east neighbor crowed, and soon it was dawn, and Jin people were still standing firmly on the ground. He remembered the shouts he heard in his dream and understood that the golden man was a prize given to him by the gods in heaven. On second thought, I just did what I should do, and I don't deserve such a reward. So, he made three obeisances in the air, which was a thank-you to the gods. The next day, he called the boys in the village and sent the gold man to the palace of the Yellow Emperor. When the Yellow Emperor asked about the origin of the Jin people, he only said that he found it by accident and said it was a thing in the world. It should be used by people all over the world. I found it by accident, but I dare not take it for personal use. I'm here to present the award. The Yellow Emperor knew his noble personality and accepted it with a smile. However, after four or five days, just as the Yellow Emperor and his ministers were looking at the Golden Man, suddenly a light came and the Golden Man disappeared. The Yellow Emperor felt very uncomfortable, but he didn't know where the Golden Man was, so he sent someone to inform Cang Xie.

Cang Xie was sleeping soundly, but in his dream, he heard someone shouting, "Cang Xie, you don't want the golden man who was given by the Jade Emperor." . What do you want? Cang Xie said in a dream: I want a bumper harvest of grain, so that all people in the world can have food. The man said, ok, I'll report to the jade emperor and ask him to take back the gold man and send you some millet. Hearing this, Cang Xie woke up, looked out of the window and saw the stars all over the sky. Knowing that he was dreaming, he didn't think much and fell asleep again.

The next day, the weather was fine and there were no clouds in Wan Li. Cang Xie was about to go out when he saw the falling grain in the sky. Particles are denser than raindrops. It rained for half an hour, and the ground accumulated more than a foot before stopping. Cang Xie was pleasantly surprised, and hurried out to see that the village was covered with grains and mountains. The villagers were also surprised. Everyone wanted millet at home.

At this moment, Cang Xie suddenly remembered the scene in the dream. Knowing that this was the jade emperor's reward for himself, he hurried to read Huangdi Daily. On the way, I met people sent by the Yellow Emperor, explained the situation to each other and went to see the Yellow Emperor together. After listening to Cang Xie's report, Huangdi deeply felt that Cang Xie's contribution was worthy of great praise. So he took Grain Rain Day as a festival, called Grain Rain Day, and ordered people all over the world to sing and dance crazily on this day every year, thanking God. Since then, Grain Rain Festival has continued. People in Baishui Town regard this day as a festival to worship Cang Xie.
