Guyu is one of the 24 solar terms and the last solar term of spring. As the old saying goes, "a year of drought and flood depends on the grain rain", this proverb shows the importance of the valley rain to farming. So, whether this year is a drought or a flood, we might as well take a look at what the saying goes.

1. Grain and rain farming

The rainy season is the critical period for spring plowing and spring planting. At this time, farmers should arrange their agricultural activities reasonably according to the weather conditions. When the rain arrives, the earth warms up and the rain increases, which is the best time to sow cereal crops. At this time, the farmers began to get busy, plowing the fields, sowing seeds, and watering, hoping that a year's hard work would be exchanged for the joy of a good harvest.

2. Drought and flood forecasting

The weather during the rainy season is unpredictable, which often determines whether the year is dry or flooded. In China, there are many prediction methods for valley rain weather, the most famous of which is the "valley rain three weather". The so-called "three waits for valley rain" is to predict the weather trend in the future period according to the weather conditions in the first three days of valley rain.

1. Three days before the rain: Refers to the weather conditions in the three days before the valley rain. If the weather is sunny and sunny for these three days, then the weather will be mainly sunny for the next period of time, which is conducive to the growth of crops. On the contrary, if it is rainy for three days, then the weather will be mainly rainy for the next period of time, which may lead to drought and flood disasters.

2. Rain and sunshine: If it is sunny on the day of Guyu, then the weather will be mainly sunny for the next period of time. In this case, the crops grow well, which is conducive to a good harvest.

3. Grain rain and three rains: If it is a rainy day on the day of the rain in the valley, then the weather will be dominated by rain for the next period of time. In this case, farmers should pay close attention to the amount of rainfall to prevent drought and flood disasters.

3. Interpretation of colloquialisms

There are many sayings about Gu Yu, and here are some common sayings:

1. "Before and after the rain in the valley, plant melons and beans": This saying tells us that the rain in the valley is the best time to sow melon and bean crops. At this time, the temperature is suitable and the rain is abundant, which is conducive to the germination and growth of seeds.

2. "When it rains in the valley, a hundred grains grow": This saying means that if there is a moderate amount of rain during the rainy season, then the crops will be able to thrive and be conducive to a good harvest.

3. "The grain rains without rain, the farmers suffer": This proverb expresses the farmers' desire for rain. If there is no rain during the rainy season, there may be drought conditions in the following period, which will make agricultural production difficult.

Fourth, weather changes

In the rainy season, the weather in most parts of our country gradually warms up, and the rain increases. However, the weather is very changeable, and sometimes there is a phenomenon of "inverted spring cold", which makes the temperature drop suddenly. In this case, farmers should pay attention to weather changes in time and take corresponding preventive measures.

5. Agricultural impacts

The weather during the rainy season has an important impact on agricultural production. Suitable weather is conducive to the growth of crops and is conducive to a good harvest. However, if the weather is abnormal, such as drought, flood, hail, etc., it may bring losses to agricultural production. Therefore, farmers should make reasonable arrangements for agricultural activities according to weather conditions to ensure the smooth progress of agricultural production.

6. Preventive measures

In order to cope with the possible drought and flood disasters during the rainy season, farmers can take the following preventive measures:

1. Pay attention to the weather forecast: keep abreast of weather changes and arrange agricultural activities reasonably.

2. Construction of water conservancy facilities: construction of reservoirs, canals and other water conservancy facilities to ensure sufficient water sources.

3. Soil improvement: Adopt measures such as deep ploughing and fertilization to improve the water and fertilizer retention capacity of the soil.

4. Adjust the planting structure: choose suitable crops for planting according to the local climatic conditions.

5. Take insurance measures: Insure crops to reduce losses caused by natural disasters.

In short, the rainy season is a critical period for agricultural production. We should make rational arrangements for agricultural activities according to the weather conditions and strive to achieve a bumper agricultural harvest. At the same time, we should also pay attention to weather changes and take corresponding precautions to ensure the smooth progress of agricultural production. As the old saying goes, "a year of drought and flood looks at the grain rain", let us look forward to this year's grain rain can bring a good harvest.
