As the name suggests, "Guyu" is "sowing grain rain", and it is also the best season for sowing seeds and transplanting seedlings, planting melons and beans. Among the 24 solar terms in agriculture, it is the last solar term of spring.
Every year on April 19th ~ 21st, when the sun reaches the ecliptic longitude angle of 30 degrees, it is "valley rain". In the spring valley, we can hear the birds of "cuckoo" and "cuckoo".
Picture 01~02): It will rain during the rainy season
In this issue of pictures and texts, Qingjiang Crane will focus on and chat with all of you and teachers about the topic of "Gu Yu" solar terms, aiming to share in detail the weather changes before and after "Gu Yu", what impact on agricultural production? What effective measures should we take to avoid these risks from nature and the negative impact on agricultural production? I hope you like and actively participate in interactive comments, forward and share this issue of pictures and texts.
Guyu is the last solar term of spring:
"Guyu" is the last agricultural solar term of spring, marking the end of spring and the beginning of summer.
Meng Haoran's poem "Spring Dawn" said: "I don't know when I sleep in spring, and I smell birds everywhere." The sound of wind and rain comes at night, and the flowers fall to know how much. It is written about the rain in the season of "Gu Yu", which expresses the author's praise and love for spring, and reveals the author's pity for time.
Gu Yu carries the joy of the rejuvenation of the earth and the growth of all things, and also indicates the coming hot summer.

The name of Guyu comes from the observation and perception of natural phenomena by the ancients, which means that at this time, the rain is moist and the grain grows vigorously, which is an important node of agricultural activities.
"Gu Yu" has 3 waits: one is the beginning of Ping. The second waiting dove brushes its feathers. Three waits hoopoe descended on Sang. Translated into "peasant language", it is: when the rain increases in the valley rain, duckweed begins to grow, cuckoo chirping begins to "prompt" the neighbors to sow seeds, and the mulberry trees gradually see "hoopoe birds".
Weather characteristics before and after the rain in the valley:
During the rainy season, the temperature gradually rises and the rain is abundant. There is a folk proverb called "Qingming breaks the snow, the valley rain breaks the frost". The precipitation in nature is really after the "valley rain" so that there will be no more "frost", and the cold wave weather is basically over.

During this period, most of the continent enters a rainy spring period, with increased precipitation and humid air. "Valley rain" wants rain, taboo sunny weather, rainy is the best. The precipitation in the southern region is particularly obvious, with continuous drizzle and mist, forming a spring scene like an ink painting. There was a rain before and after "Gu Yu", which was better than a show. It can be seen that the rain of "valley rain" is commendable and necessary.
Although the precipitation in the northern region is relatively small, the rise in temperature makes the earth warm up and full of spring.
The impact of natural weather changes on agricultural production during the rainy season:
The natural weather changes during the rainy season will have a profound impact on agricultural production.
For cereal crops, abundant rainfall during the grain rains is the key to crop growth and development. At this time, crops need a lot of water to support their vegetative growth and reproductive growth, and the arrival of Guyu just meets this demand and lays a solid foundation for a bumper harvest. "If it doesn't rain in the valley, the crops are afraid" refers to the importance of rain in this season.
Picture 07~08): It rains well in the valley rainy season
At the same time, the valley rain is also an important period for spring crops, and farmers are busy sowing seeds (alpine), applying fertilizer, and looking forward to a good harvest in autumn. This period is also the post-maturity period of oil crops such as winter crops such as rapeseed, so it is necessary to pay attention to weather changes at all times and use drugs at the right time to ensure a bumper harvest of oil crops.
In addition to cereal crops, grain rains also have a positive impact on other crops. After the fruit tree is flowered, it is in the physiological fruit drop stage, the extraction period of new shoots, and the young leaf spreading stage. With the rise of temperature and the increase of precipitation, the incidence probability of pests and diseases increases simultaneously, and the daily management of orchards must be carefully strengthened, so that the management measures are in place in a timely manner, not lagging behind, not lacking, not lacking.
"Qingming sees buds, Gu Yu sees tea". "Guyu Tea" is the best tea of the year, and it is the best tea in tea. Because compared with the nobility of "Qingming Tea", the price of "Guyu Tea" is more down-to-earth. And the tea quality is also very good, which can match the price.

At the same time, fruit trees, vegetables, etc. need to be irrigated and fertilized at this time to ensure their strong growth. In addition, Guyu also promotes the growth of grasslands and woodlands, providing favorable conditions for the protection and restoration of the ecological environment.
In the rainy season, precautions in the process of agricultural production:
In the rainy season, although good natural resources bring hope and the foundation for a bumper harvest to agricultural production, it is also necessary to pay attention to some occasional "adversity" problems before and after the rainy season.
First of all, due to the increase of rainfall, it is easy to lead to excessive soil water and humidity, which affects the root respiration and root growth of crops. Therefore, farmers need to pay attention to drainage and flood prevention to ensure the healthy growth of crops and avoid the occurrence of root diseases of crops.
Compared with the low-lying places of the orchard, after the water is waterlogged, the fruit trees will fall flowers and fruits, and the fruit trees will not be stable, and the root system of the fruit trees will be easy to rot.

Secondly, the period of valley rain is also a period of high incidence of pests and diseases. The humid environment provides favorable conditions for the breeding of pests and diseases, so farmers need to strengthen the prevention and control of pests and diseases, and take scientific and reasonable control measures to protect the growth of crops.
Before and after the rain in the valley is the vegetative growth and development period of dry-bred seedlings and paddy field "plate seedlings", under the influence of "high and low" temperature, the temperature difference between day and night is too large, which is easy to make rice seedlings suffer from blight and root rot. Those who sow early may also suffer from "bacterial wilt" and "yellow wilt".
Therefore, the comprehensive prevention and control of diseases and insect pests at the seedling stage of rice and corn seedlings should be strengthened according to the actual production needs.
It can be used with 80% allicin chloramphenicol EC 800~1000 times, and 3% methamethoxamine EC 800~1000 times, and "Miao Qingqing", "Liang Miao", "Zhuang Miao", "Three Days Net", "One Day Green", "Dead Seedlings and Rotten Roots First Aid" and other multi-functional foliar fertilizers can be used to prevent and treat various diseases and disturbances of seedlings at the seedling stage.

In addition, the climate change in the rainy season is larger, and the temperature difference between morning and evening is large, so farmers need to pay attention to keeping warm and preventing heatstroke to avoid affecting their health due to climate change. All kinds of seedlings that are avoided and cultivated are subject to "freezing cold" or "burning seedlings".
Words written at the end of "Valley Rain Season":
The Guyu solar term is one of the 24 solar terms in agriculture, which is a gift from nature and the expectation of farmers.
It brings vitality and hope, but also challenges and responsibilities. In this late spring and early summer, let us feel the blessings of nature together, watch over this field full of hope, and look forward to one harvest season after another.
Through an in-depth understanding of the Guyu solar term, it is not difficult for us to find that it is not only a time node, but also a manifestation of life attitude and natural wisdom.
Picture 15~16): Today's valley rain, everything is not appropriate
It teaches us to conform to nature, to revere life, and to cherish the land that nurtures us more. In the days to come, let us face every solar term and every harvest with a more awe and gratitude attitude, and jointly protect this beautiful homeland.
