How to crack the spring thunder

Spring thunder, everything grows? Is it time to be scared? Jiujiu? On sunny days, the temperature rises and the rain increases. Every year around March 6 of the Gregorian calendar is a shock. Let's take a brief look at how to crack the spring thunder.

How to crack the spring thunder

In the season of fright, the spring is bright and everything is revived. In ancient times, when peach blossoms were red, plum blossoms were white, orioles sang and swallows came, most areas had already entered spring ploughing. When all kinds of insects dormant and hibernating in the soil are awakened, eggs will begin to ovulate in winter, so it can be seen that fright is a solar term reflecting natural phenology.

Spring thunder scares all insects? Warm climate conditions are conducive to the occurrence and spread of many diseases and insect pests, and weeds in the fields have sprouted. It is necessary to do a good job in pest control and intertillage weeding in time. ? Peach blossom, swine fever? Attention should also be paid to the epidemic prevention of poultry and livestock.

A thunderous reminder of fear

Called before the thunder, it struck in the dark on the 49 th. If it thunders before the sting, there will be continuous rainfall and disasters this year. It means that if lightning occurs before the solar term, it means that there may be abnormal weather, continuous rainfall and disasters; When the solar terms are suddenly cold and warm, the proverbs that predict the weather in the later period according to the cold and warm are: cold wave impact, spring equinox is warm? Wait; The wind with prickly knots is also used as a basis for predicting the weather in the later period, such as? Scared by the north wind, spend the winter from the beginning? 、? When the south wind blows, the seedlings are planted late? ; What else is there? Startled, warm and harmonious, toad singing folk songs? Wait a minute.

Wang Hongmin, member of the National Technical Committee for Standardization of Building Electrical Devices: Outside, we should consider the lightning activity area and see the distance of lightning activity. Generally, we can judge the distance by listening to thunder. Don't hide under lightning rods and trees. Don't open an umbrella in an open place, because the umbrella has a needle tip and the electric field intensity should be concentrated. Don't use your mobile phone in an open place. Squat down and put your feet together.

Experts finally stressed that in case of thunderstorm, citizens had better hide in buildings with metal doors and windows or lightning rods. The car with metal body is also the best? Lightning protection station? Once these buildings or cars are struck by lightning, their metal frames or lightning protection devices or the metal itself will lead lightning current into the ground.

The season of fear waits for no man

The season waits for no one, and a moment is worth a thousand dollars. In most areas, the average temperature of scary solar terms is generally 12℃ to 14℃, which is more than 3℃ higher than rainy solar terms, and it is the solar term with the fastest annual warming. The sunshine time has also increased significantly. However, due to the alternation of cold and warm air, the weather is unstable and the temperature fluctuates greatly. In the Yangtze River valley area in the southeast of South China, the cold season temperature is stable above 65438 02℃ in most years, which is beneficial to the sowing of rice and corn. The average daily temperature in other areas is lower than 12℃ for more than three consecutive days, so it is not allowed to sow blindly early.

Although the temperature rises rapidly, the increase of rainfall is limited. The total rainfall in central and northwest South China is only about 10 mm, and spring drought often begins after winter drought all the year round. At this time, the booting stage of wheat and flowering stage of rape are in a period of high water demand and are sensitive to water demand. Spring drought often becomes an important factor affecting the output of Koharu. Afforestation should also consider this climate feature, plant logistics and water, and strive to improve the survival rate of saplings.

Effects of Stings on Agriculture in Different Regions

The characteristics of major agricultural activities in various regions of China are as follows.

Northeast China: Carry out all-round land preparation by pressing and harrowing, turn over the soil in autumn, harrow the ground with broken soil, collapse the ridge with top slurry, open furrows in spring and close the ridge in autumn. Millet, spring wheat, barley and rape are sown on hillsides and hillsides unsuitable for moisture conservation. Pick dung, deliver dung, and pat garbage. Forest fire prevention. South China: Stunned, not plowing, but three to five days? After thawing, grab the rake and store more water. Winter wheat generally turns green, topdressing and watering. Sow in early spring and raise seedlings with Chinese yam.

Northwest:? After the sting festival, the cultivated land will not stop? . Sow spring wheat and rake spring corn to keep water. Prevention of livestock damage in winter wheat field.

Southwest: Top-dressing panicle fertilizer for summer crops, strengthening weeding, timely irrigation, and preventing and controlling pests and diseases. The first batch of double-cropping early rice was sown in the southern and northern valleys, and early corn was sown in other areas. Sweet potato seedling raising. Pay close attention to the work of ploughing the soil, tidying up the seedling fields, accumulating fertilizer and planting.

Central China: management of fertilizer and water in wheat fields, watching seedlings uproot and save fertilizer, watching soil moisture, watching seedlings, and watching irrigation and pulling up water in the sky. Intertillage weeds and roots to control pests and diseases. Cultivate sweet potatoes in hotbeds. Prepare early rice seedlings, cut spring potatoes and accelerate germination. Topdressing rape leaves to prevent the spread of pests and diseases. Soil preparation and fertilization in cotton field. Young tea gardens should be trimmed, and adult tea gardens should be trimmed lightly to prevent pests. Continue planting trees. Strengthen epidemic prevention of livestock and poultry.

South China: Continue to sow early rice, cultivate strong seedlings and organize Honda. Corn sowing, thinning and fixing seedlings. Early maize intertillage, soil tillage and forced fertilization. Wheat harvest Sow early-maturing soybeans, plant sugarcane in spring, harvest sugarcane in spring, treat perennial roots, and cultivate sugarcane in autumn for topdressing. North China:? Scared? In this season, the winter wheat in North China began to turn green, and the soil was still frozen and thawed alternately. Raking the ground in time is an important measure to reduce water evaporation. ? Being in a daze without raking the ground is like steaming steamed bread to leave gas? This is a valuable experience for local people to prevent drought and conserve moisture.

Wheat in the south of the Yangtze River has been jointing and rape has begun to blossom. There is a high demand for water and fertilizer, so topdressing should be done in time, and proper irrigation should be done in dry and rainy places.
