Kiwifruit encounters "cold spring" measures are not necessary
Cold damage period
Before April 20th of each year, it may be the time when the cold spring occurs. For kiwifruit, the bud sprouting leaves to the buds in the early stage is the most vulnerable to the cold weather hazard.
Basic knowledge
In the spring, the germination of kiwifruit leaves is in the bud stage. If the lower limit temperature is lower than 5 °C, the kiwi may suffer from cold damage. When the lower limit temperature is lower than 0 °C in spring, freezing damage will occur. This is a critical temperature that must be remembered for cold damage.
Master the law
When the critical temperature of the cold spring occurs, if the cloudy weather and rainfall occur at the same time, it will impact or ease the cold damage, but remember that when the critical temperature of cold damage occurs (or forecast), if it is sunny or windless, it is cold damage (freezing damage) It is most likely to aggravate the meteorological conditions that occur. Such meteorological conditions are alarms that must be engraved in the heart.
Proper measures
At present, the most effective, most feasible and quickest way to prevent and respond to the downfall is the orchard. Under the premise of safety, as long as a certain amount of smoke layer with a certain thickness is formed over the park, the fruit trees can be protected from the cold damage.
Be prepared
In areas where cold damage frequently occurs, prepare smoked materials such as sawn wood, hard firewood, waste engine oil, firewood, etc. in advance to prevent precautions.
Scientific fumigation
Smoke and smoke are cold, seemingly simple, but it is very complicated, requires a lot, and the details are very strict. The amount of smoked material per unit area, the location of the smoked material, the quality requirements of the smoked material, the method of igniting the smoked material, the ignition time of the smoked material, the time of smoking after the smoked material is ignited, the lowest temperature of the cold spring, the real-time monitoring time, etc. It has direct influence and relationship on fumigation and chilling, and must be strictly understood and mastered.

Antipyretic:
Something that reduces fever or quells it.
There are 3 classes of antipyretic medications that are sold OTC (over-the-counter) without prescription:
Salicylates -- aspirin (acetylsalicylic acid), choline salicylate (Arthropan), magnesium salicylate (Arthriten), and sodium salicylate (Scot-Tussin Original);
Acetaminophen (Tylenol); and
Nonsteroidal anti-inflammatory drugs (NSAIDs) -- ibuprofen (Advil), naproxen (Naprosyn, Aleve), and ketoprofen.
From anti-, against + the Greek pyretos, fever from pyr, fire. The same root gives rise to pyrexia, a medical term for fever.
Antipyretic, from the Greek anti, against, and pyreticus, pertaining to fever, are substances that reduce fever. Antipyretics cause the hypothalamus to override a prostaglandin-induced increase in temperature. The body then works to lower the temperature, resulting in a reduction in fever.
Most antipyretic medications have other purposes. The most common antipyretics in the United States are ibuprofen and aspirin, which are used primarily as pain relievers. Non-steroidal anti-inflammatory drugs (NSAIDs) are antipyretic, anti-inflammatory, and pain relievers.
Pain-killer:
Painkiller is any member of the group of drugs used to achieve analgesia, relief from pain.
Analgesic drugs act in various ways on the peripheral and central nervous systems. They are distinct from anesthetics, which reversibly eliminate sensation. Analgesics include paracetamol (known in North America as acetaminophen or simply APAP), the non-steroidal anti-inflammatory drugs (NSAIDs) such as the salicylates, and opioid drugs such as morphine and oxycodone.
In choosing analgesics, the severity and response to other medication determines the choice of agent; the World Health Organization (WHO) pain ladder specifies mild analgesics as its first step.
Analgesic choice is also determined by the type of pain: For neuropathic pain, traditional analgesics are less effective, and there is often benefit from classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants.
