Time flies, and now it has come to March, and it is about to be the stinging solar term, it stands to reason that the weather will get better and better, but just recently, the cold air has affected the central and eastern regions, the temperature in the central and eastern regions has dropped, and there have been blizzards in some areas, making this spring a little cold!
According to the latest information released by the meteorological department, in recent days, there has been snowfall in Shaanxi and Gansu, and in the next three days, there will be snowfall in Xinjiang and **, and people living in these places should take precautions.
With the arrival of a new wave of cold air, the temperature of Jianghuai and Huanghuai changed, the temperature in South China and the southern part of Jiangnan rose, and the temperature in Jiangnan dropped on February 6.
A new round of precipitation is coming, is the cold spring that occurs once in 60 years coming?
Recently, the temperature in most areas has risen, the wind is beautiful, the weather is getting warmer and warmer, the breath of spring is getting stronger and stronger, the plants are budding and full of vitality, but even so, there is still a cold air No. 4 coming, the temperature drop will change, fortunately in these two days, the temperature in Jianghan, Jianghuai, and Jiangnan areas has risen to more than 10, and South China may exceed 20, obviously not as cold as before.
Cold air affects the central and eastern regions, the central and eastern regionsThe weather has changed:
Rainfall distribution:Light to moderate rain (snow) will occur in South China, Jiangnan, Northwest China, North China, Jianghan, Guizhou and other regions, of which heavy rain will occur in parts of Jianghuai and Jiangnan;
Snowfall distribution:**Heavy snowfall will occur in the west and southwest of Xinjiang;
According to the experience of the older generation, spring ploughing generally begins before and after the sting, this is because the sting is the third solar term in the 24 solar terms, and it is also the middle of spring, the temperature at this time gradually warms up, the soil slowly thaws, the plants begin to sprout and grow, and farmers can start spring ploughing work.
Due to the influence of cold air, rain and snow in the central and eastern regions may affect spring ploughing.
Excessive rainfall in spring can lead to water accumulation in the soil, which can cause crop roots to become hypoxic and rot, thus affecting their growth. In addition, excessive rainfall can easily lead to flooding of farmland, resulting in damage or even death of crops, so farmers need to pay close attention to the weather conditions and take drainage measures in time to avoid losses due to excessive rainfall!
However, a prolonged drought in spring can also have a negative impact on crop growth, as insufficient rainfall will gradually evaporate the moisture in the soil, causing crops to wilt and grow slowly due to lack of water, and farmers need to provide sufficient water for crops through irrigation.
In addition, spring snowfall will also have an impact on crops, although a small amount of snowfall can add some moisture to crops, but if there is too much snowfall, it will crush the greenhouse, bringing economic losses to farmers, so when encountering heavy snowfall in spring, farmers need to take preventive measures in time.
In the author's opinion, the impact of spring rain and snow on crops cannot be ignored, and only by taking corresponding preventive measures can we ensure the healthy growth of crops.
In short, under the influence of cold air, the temperature in the central and eastern regions has changed to varying degrees, and a new round of precipitation is coming, with snowfall in Shaanxi and Gansu, and light to moderate snow in some areas such as Jiangnan and South China. In addition, Jianghan, Jianghuai, Jiangnan, South China, Guizhou and other regions will have light to moderate rain, if such weather continues, it is not uncommon to have a "cold spring" once in 60 years!
