Time flies so fast, tomorrow will officially usher in the valley rain solar term, the valley rain is the last solar term of spring, after the valley rain we will officially enter the summer. The word grain rain comes from the meaning of "rain gives birth to a hundred grains", this solar term wheat is in the heading and flowering period, the rain is very conducive to the wheat fullness, and this solar term is the busy season of spring sowing, the crops have a large demand for water, and the rain is very conducive to the grain harvest.
"Tea Shu" records: "Qingming is too early, the beginning of summer is too late, before and after the valley rain, the time is moderate", before and after the valley rain is the peak time period of tea picking, the tea leaves picked at this time are delicate and fragrant, the taste is good, we call it "Gu Yu tea", legend has the effect of this day's tea to ward off evil and clear the fire. In addition to the custom of "picking tea and drinking tea" on this day, there is also a saying of "walking Gu Yu" on this day in the mainland, that is, women want to go to the wild for a walk on this day, which means that they are integrated with nature, which can play a role in strengthening the body.
As the old saying goes, "plant the grain in the rainy season", it is said that the rainy season is a good time to sow seeds, and every year in the rainy season, it is of great significance to farmers, people prepare farm tools and seeds early, once the rain arrives as scheduled, there will be a busy and hopeful labor scene in the field.
For the peasants are hoping that the wind and rain will be smooth, the five grains will be abundant, our ancestors in the long-term labor production summed up a lot of experience, in the mainland folk there is "the valley rain is three elephants, the graves are everywhere" said, that is, the valley rain solar terms appear three kinds of weather characteristics, then it indicates that the growth of crops will be seriously affected, in ancient times the material is underdeveloped, once the grain harvest is poor, then it is easy to cause famine, so that the phenomenon of graves everywhere. So what do the "three elephants" mean here? Let's find out together.
The first image: the valley rain and the sunny day
Valley rain is a solar term that reflects precipitation, and when it comes to the valley rain, the rainfall in the southern part of the mainland will increase significantly, and there will often be a long period of rainy weather. If it is a sunny day on the day of the Guyu solar term, then it is not a good omen.
According to the experience of our ancestors, if the rain is sunny on the day, it often indicates that the rain will be less in the future, and it is prone to drought. In ancient times, there was no modern irrigation system, and farmers could only rely on natural rainfall to nourish the land.
Just as the agricultural proverb says, "the valley rain is a prosperous flood, a moment is worth a thousand gold", the mild weather in the valley rain season is a good season for sowing seedlings and transplanting seedlings, melons and beans, at this time the rain is very beneficial to the growth of crops, so the rain in the valley rain season is very much expected by farmers; and if the grain rain does not rain, not only the growth of wheat will be affected, but also the emergence and growth of spring sowing crops will also be affected, and the yield of crops will be seriously reduced.
The second elephant: the valley rain and frost
As the old saying goes, "Qingming breaks the snow, the valley rain breaks the frost", under normal circumstances, the Qingming solar term in the northern part of the mainland is a symbol of "final snow", and the valley rain solar term is a symbol of "final frost".
Wheat is in the heading and filling period, if it is frosty at this time, then the wheat is easy to suffer from frost damage and reduce yield; at the same time, the grain rain solar term is the time of spring sowing, if there is frost at this time, then the seedlings that have just been unearthed are easy to suffer from frost damage and die; in addition, the fruit tree of the valley rain solar term is in the flowering and fruiting period, if it encounters frost, then it will lead to a large number of flowers and fruits, so the frost of the valley rain solar term is very undesirable for farmers to see.
If the crops suffer from frost damage, then we can spray the frozen crops with 400 times potassium dihydrogen phosphate foliar fertilizer or 0.01% brassin, which can allow the frozen crops to recover their growth quickly.
The third elephant: Gu Yu is afraid of the south wind
According to the experience of our ancestors, the south wind on the day of the Guyu solar term is not a good sign, the agricultural proverb says "the south wind of the valley rain, the dog days are rainstormy", which means that if the south wind blows on the day of the Guyu solar term, then it indicates that the dog days will be very rainstormy.
Dog days are the time period when crops grow the fastest, and if there are frequent heavy rains during this time, then crops are easily waterlogged, and the growth of crops will be seriously affected. In addition, heavy rains will also lead to the occurrence of disasters such as mudslides, and people's production and life will be seriously affected.
Summary, with the arrival of the valley rain solar term, the next thing to appear is the summer solar term, the valley rain solar term is the busy season for farmers to sow in spring, the old saying "the valley rain is three elephants, the graves are everywhere", the three elephants here refer to the valley rain is sunny, the valley rain is frosty, the valley rain blows the south wind, according to the experience of our ancestors, the valley rain appears these three weather phenomena will lead to a reduction in crop yield, are not a good sign.
