How to prevent falls in snow?What is the recipe for safe production at low temperatures?How to take care of wheat seedlings in cold weather?Recently, Henan Province has continued to have low temperature freezing rain and snow weather, and the weather forecast of the meteorological department shows that the low temperature weather in our province will continue due to the impact of the cold wave.
On December 17, the reporter interviewed some chief science popularization experts in our province to provide an emergency reminder and suggestion for citizens in the fields of health, safe production, wheat cultivation, fruit and vegetable planting, etc.
Do not apply warm compresses immediately after an injury
Zhang Hui, chief science popularization expert in Henan Province, director of the Heart ** Center of the Second Affiliated Hospital of Zhengzhou University, and chief physician of the Department of Cardiovascular Medicine, reminded the public that when walking on snowy days, the waist and knees are slightly bent, the center of gravity should be lowered, and the soles of the feet should be as close to the ground as possible, alternating rubbing. SocietyTake the "penguin step" anti-slip: Walk slowly with the weight of the body falling on the front foot, leaning forward slightly, like skiing, and walking with the feet shoulder-width apart. In doing so, the chassis is large and the center of gravity is stable.
Once you fall, don't panic, you should be calm and try first to see if there is obvious pain and tissue damage. If the condition of the hands and feet is not serious, you can first turn sideways, turn to any direction that is convenient and comfortable, bend your legs and flip your body in a prone position, so that your knees and elbows are on the ground, and use their strength to support the whole body. In this process, if there is a relatively stable object around you, you can stand up with the help of it.
If there is only a minor soft tissue sprain, ice can be applied to the injury within 72 hours to constrict blood vessels, reduce local congestion, and reduce pain and swelling. Be careful not to apply warm compresses immediately after injury, otherwise it will dilate the blood vessels and make the swelling worse.
If there is a lot of pain in a certain area, do not force support, but move gradually, observe whether the symptoms worsen, rule out emergencies such as fractures, and seek medical help. If a deformity of the fall is found, such as a protrusion, accompanied by pain and limited movement, it may be a fracture and you need to seek medical attention immediately. When a fracture occurs, incorrect movement may cause an aggravation of fracture displacement. In an emergency, a scarf, book, etc. can be used to simply fix the fracture.
If you have chest pain, lower back, inability to sit up, stand, etc., and there is a possibility of spinal fracture, it is taboo to move the injured person at will, and the injured person should be carried to the hospital with a hard bed. If a bleeding wound is found after a fall or if bone is directly exposed to an open wound, it is best to temporarily dress the wound with clean gauze or a towel and dial "120" on the spot.
Lan Chao, the chief science popularization expert of Henan Province, the head of the Zhengdong Branch of the First Affiliated Emergency Medicine Department of Zhengzhou University and the director of EICU, reminded the public that frostbite and other diseases are prone to occur in rainy and snowy weather, especially those who need to work in the field, such as sanitation workers, etc., to prevent the occurrence of frostbite. In severe cases, it may be black or purple-brown, and pain loss may occur, and frostbite may occur.
Once frostbite occurs, it is necessary to leave the cold environment immediately, and soak the limbs in warm water of about 40 (not too high) until the first turns red, and the tissue becomes soft, and the time should not be too long. When there is no lukewarm water, the limb can be placed on the warm part of the body of the self or the rescuer, such as the armpit and abdomen, to achieve the purpose of rewarming. Avoid rubbing the frostbite area, and seek medical attention immediately if the frostbite is severe.
In addition, in addition to the high incidence of falls, fractures and frostbite, cardiovascular and cerebrovascular diseases, respiratory diseases, rheumatoid arthritis, etc., especially the elderly and patients with chronic diseases should pay more attention to keeping warm, eating lightly, paying attention to rest, avoiding emotional agitation, taking medication regularly, and going to the hospital regularly for reexamination.
Pay attention to safety production in cold weather
Li Qingsong, chief science popularization expert of Henan Province and vice chairman and secretary general of the Provincial Association of Safety Production and Occupational Health, reminded the public that extreme weather in winter has a great impact on agricultural production, and it is necessary to take measures such as preventing wind and heavy snow from damaging greenhouses. The cold wave has a relatively small impact on the facilities and equipment of industrial enterprises, but it has a greater impact on operators.
In low temperature weather, due to thick clothing, lower body temperature, wearing cold-proof hats, masks, glasses, gloves, etc., will lead to a decrease in reaction speed, inadequate actions, and decreased hearing and vision, which will affect the reception of operation instructions, sound and light signals, and then lead to unsafe behaviors or misoperations, and the probability of accidents will increase. Especially in field work, strong winds, low temperatures, fatigue, and dim vision are the main causes of accidents. In addition, fire prevention in winter is also a major event for production safety, so special attention should be paid to it.
The rain and snow were generally favorable for the safe wintering of wheat
The rain and snow have brought some inconvenience to people's lives, but for wheat, it is good news.
Li Xiangdong, the chief science popularization expert of Henan Province, an expert on high-yield cultivation positions in the wheat industry technology system of Henan Province, and a researcher at the Wheat Research Institute of Henan Academy of Agricultural Sciences, believes that the large-scale rain and snow process is generally beneficial to the safe wintering of wheat in our province.
First of all, due to the lack of effective rainfall for a long time since November, some plots have experienced drought, and some plots of rotary tillage and land preparation, unreal suppression, and soil deficiency are more susceptible to low temperature frost damage. The snowfall intensity is relatively large, which can fully replenish soil moisture, increase soil moisture content, alleviate drought and improve the cold resistance of wheat.
Secondly, although the cooling range is large, it is also a gradual process, which is conducive to the cold resistance exercise of wheat before wintering. As the saying goes, "the wheat seedlings are covered with snowflake quilts, and the next year they sleep with buns", which means that if the snow is relatively heavy in winter, the wheat harvest in the coming year is very promisingHeavy snow covers wheat, which is equivalent to covering wheat with a thick quilt, raising the ground temperature, which is very beneficial to wheat to resist low temperature and safely overwinter.
Generally speaking, the normal wheat field wintering period does not need to take special measures, for some of the wheat fields that grow weak seedlings and sow too late single single seedling, it is necessary to observe the seedling situation in time after low temperature, and take corresponding countermeasures, if there is frost damage, after the temperature rises to more than 3, take topdressing fast-acting fertilizers, spraying nutrients, plant growth regulators, etc., to promote its recovery.
