Luoyang Peony is the best place in the world, but in Luoyang, it is said that the peony in Tuqiao Village of Qishan Town in the old town is the most famous. On February 14, the reporter learned from the village of Tuqiao that there were more than 400 farmers and 2,700 mu of land in the village. 80% of the people cultivated peony and the average annual income was 50,000 to 100,000 yuan. Tsuchihashi Village has a history of cultivating peony for many years. Before and after 1997, Li Longzhang and others in Tuqiao Village had devoted many years of painstaking research to finding a good way to rapidly breed peony and to blossom peony for four seasons. It is the use of these two technologies that turned the villagers in Tuqiao village all at once. At present, the village can provide 4 million peony seedlings to the community each year. The Luoyang Tuqiao Huamu Seedling Company established by Li Longzhang and others provides 1.5 million peony seedlings each year. The village has many cultivars and a large scale of cultivation. It is at the leading level both at home and abroad. In 2000, it was named “Hometown of Chinese Peony†by the Chinese Flower Association and other organizations. In fact, these two technologies are also very simple to say, that is, grafting and anti-season cultivation. Grafting is used for quick seedlings, and off-season cultivation is used to advance or postpone peony flowering. It is divided into cultivating and suppressing cultivation. The natural breeding of peony depends on the ramets, which is very slow. The method of grafting peony by grafting is not only simple in operation technology but also can greatly increase the breeding speed of peony. Grafting materials generally use peony root and peony scion. Scorpion root is used to make rootstocks. To use 2 to 3 years old peony root, the skin is required to be smooth, free from diseases and insect pests, non-invasive, burns, excessively dehydrated, cross-sectional discoloration, or chrysanthemum heart spot, etc., 10 to 15 cm long, thick 1 to 3 centimeters. The collection of peony scion must have specially cultivated peony varieties. Taking Luoyanghong as an example, choose 3 to 4 years old peony, 2 to 3 shoots as a plant, and press the root downwards and branches to the horizontal direction. The row spacing is 60cm, the plant spacing is 70cm, the plant root shoots The direction should be consistent with the direction of irrigation, the two roots are about 10 cm apart, and about 1580 plants can be planted per mu. In the autumn, the shoots sprouting on the surface are leveled. After two years, 15-20 panicles per plant can be harvested. Grafting method used in the past is a partial wedge-type jointing method, which is to cut the peony root to a horseshoe-shaped mouth, and insert the scrunched stalks of the offset wedge peony into the scion in advance, and then bind and wipe the mud with the tendons. At present, a one-knife grafting method is generally used to cut the roots of peony root and the peony scion, and then tie them together and wipe the mud. This method is easier to operate and more efficient. One person can graft 1000 peony seedlings a day, and flower farmers call it the "factory rapid seedling raising technology." Under normal circumstances, the grafted peony seedlings must be grown in the field for two years, and then transplanted and cultivated for three years before they can be planted. In April of each year, the peony can bloom. Nowadays, in order to meet the needs of the market, flower farmers in Tuqiao Village have used anti-season cultivation to allow peony to bloom in all seasons. Li Longzhang, general manager of Luoyang Tuqiao Huamu Seedling Co., Ltd., said that the anti-season cultivation of peony is to adjust the growth environment of peony at different times, and to control the temperature and humidity, moisture and light, and to use plant growth regulators to break the peony. The dormant state of peony eventually achieved the purpose of allowing Peony to bloom within expectations. If you want peony to bloom in the Spring Festival, you must use the cultivation, mainly to increase the temperature, the temperature is controlled at 15 °C ~ 25 °C; if you want to peony in the Mid-Autumn Festival or National Day flowering, we must use the inhibition of cultivation, mainly cooling The technical difficulty is a bit bigger than the promotion of cultivation. On the Spring Festival this year, 160,000 pots of peony listed on Luoyang were all made by cultivation. The application of rapid seedling cultivation and off-season cultivation techniques is making the peony, a precious flower, develop rapidly. It can be used not only for building gardens, urban afforestation, greening of roads, and flower exhibitions, but also gradually becoming the main species of the Annual Retreat. To millions of households. Luoyang Tuqiao Huamu Seed & Seed Company is in the process of research and innovation and is preparing to cultivate special ornamental series, promotion cultivation series, potted series, cut flower series and medicinal series of peony varieties on the market to meet different consumer demand for peony.
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.
