The rain solar term has brought a significant cooling, and many places have ushered in the "inverted spring cold", and the cold hits people
With the arrival of rainfall, the temperature plummeted, and many places experienced a "cold spring".
Changes in seasons and temperatures.
After the Lunar New Year, a new season is ushered in. It is expected that the cold air activity will also bring a large cooling next week, and the average temperature in the central and eastern parts of the country will be reduced by 8-12 degrees Celsius, and it may reach more than 20 degrees Celsius in some places. Such a significant warming tendency, which would cause temperatures to drop even more in many regions, could lead to:"Pour the spring cold"。
In addition to the arrival of rain, it also means a sharp change in temperature. For example, in Henan, the high temperature has been rising in recent times, and the maximum temperature during the day has approached 20, which makes people feel the warmth of early spring. However, when the season comes, the temperature drops dramatically, with highs dropping to freezing, accompanied by rain and snow. Such drastic temperature differences not only show the characteristics of the rainy season, but also make people feel the instability of global warming.
1、"Pour the spring cold"It is caused by a sharp drop in temperature.
It is a rainy season that has entered the rainy season, and the eastern and central parts will suffer due to the decrease in temperature. At present, in some places in northeast China and Hubei, Hunan, and western Guizhou, the cumulative temperature will reach more than 20 degrees Celsius. Such extremely low temperatures are bound to cause"Pour the spring cold"The occurrence of the event makes people feel both the coming of spring and the invasion of a cold wave.
Pour the spring cold"Not unfounded, it does have a real impact on agriculture. In the northern part of China, due to the early temperature, it is conducive to the normal growth of wheat, but the temperature drops to 7-9 or above in 24 h in extremely low temperature weather, which is easy to cause low temperature chilling injury. According to the relevant authorities, in order to avoid"Pour the spring cold"To bring adverse consequences to grain production, the northern part of our country should be irrigated in time before the arrival of cold air to reduce the fluctuation of ground temperature and facilitate the monitoring of crop growth.
2) The role of cold wave weather on grain production and its prevention.
In the south, the cold of spring can also affect crops such as rapeseed, causing leaves to freeze. Against this backdrop, early action is crucial. After snow or frost, frozen leaves and broken branches should be cleaned and effective N should be applied at the same time to promote their normal growth quickly.
In addition, aquaculture, animal husbandry and agricultural greenhouses should also pay attention to the "cold spring" in spring. For greenhouses, it is important to pay attention to snow removal in winter, and at the same time to carry out the necessary protection of the greenhouse. The livestock and poultry breeding industry should also pay attention to low temperature, frost resistance and frost resistance in winter, so as to minimize the harm of spring.
3.Abundant rain helps crops grow properly.
Although the weather is getting cooler, the right amount of rain still has a big impact on the growth of crops. As the saying goes, "the land is moist after the rain", and proper rainfall can ensure that crops can get enough water in the spring. It shows that the area is rainy and rainy, which is conducive to the normal growth of crops.
In general, although the arrival of the cold spring has brought some impact on agricultural production, after scientific prevention and treatment, farmers can still protect their crops well and ensure the normal operation of agriculture. In addition, abundant precipitation can also provide the necessary water for the normal growth of crops, which is the guarantee of a good harvest. In the context of global warming, scientific farming and taking precautions are a major issue faced by farmers, and it is also a new driving force for sustainable agricultural development.
