The scientific name of the Radermachera sinica is Radermachera sinica, and it prefers a high-temperature, humid, and sunny environment. However, if the Radermachera sinica is not cultivated properly, it can also develop many diseases. The editor will introduce four common diseases of the Radermachera sinica for you. If you also cultivate Radermachera sinica, don't miss out.

Radermachera sinica

1. Leaf spot disease:In environments with high temperature, high humidity, and poor ventilation, its leaves are prone to leaf spot disease.

Prevention and control methods: Strengthen ventilation and light transmission, and avoid prolonged water retention on the leaf surface. When a small number of diseased leaves are found, they should be removed and burned promptly, and 50% carbendazim wettable powder at 600 times dilution should be sprayed regularly, once every half month, for 3-4 consecutive times. For household potted plants, for disease spots appearing on a small number of leaves of individual plants, Dakining cream ointment can be applied.

2. Scale insects:Under conditions of high temperature, high humidity, and poor ventilation, especially when kept in a greenhouse for a long time in autumn and winter, scale insects are prone to appear on the stems and leaves of Radermachera sinica.

Prevention and control methods: Strengthen ventilation and light transmission, and pay attention to controlling environmental humidity. When a small number of live insects are found, they can be wiped off promptly with a damp cloth, or removed by sticking them off with transparent tape. In commercial cultivation, during the peak hatching period of nymphs, 25% buprofezin wettable powder at 1500 times dilution can be sprayed to kill them.

3. Mites:The main damage symptoms are new leaves becoming wrinkled and curled, and the leaf surface being uneven. It generally occurs from June to September. High temperature and dryness favor massive outbreaks of this pest, while under relatively humid conditions the pest occurs less. Acaricides such as pyridaben and hexythiazox are mainly used.

4. Aphids:One of the most common aphids is the green peach aphid. Symptoms include wrinkled and deformed leaves, and usually also glistening honeydew spots. Aphids can be seen with the naked eye.

Prevention and control methods: Spray with zinc sulfur phosphorus, omethoate, deltamethrin, etc.

Are wild boars easy to raise?

Wild boars grow up in the mountains, and if they come out to move around, they will destroy crops. Because they are used to being wild, they will eat anything. If they are raised like domestic pigs, are they easy to raise?

Are wild boars easy to raise?

Wild boars are still relatively easy to raise. Wild boars have wild habits and are good at eating raw food. Common tender corn, red sorghum, winter melon, potatoes, sweet potatoes, peanut vines, sweet potato vines, millet ears, pumpkins, and eggplants in farm households are all foods they like to eat. When first raising them domestically, they should be fed together with staple food. After one month, feed half raw food and the other half with domestic pig feed, such as cornmeal, bran, tofu residue, and starch residue, adding an appropriate amount of salt. After the wild boars have basically adapted to the captive environment, feeding them with compound feed for domestic pigs will do. However, some root plants should also be appropriately added.

Wild boars have extremely strong disease resistance and are not prone to illness, with a survival rate of over 98%. The feeding techniques are the same as for domestic pigs. Pig pens can be converted from domestic pig pens, ordinary old houses, or warehouses. However, because wild boars are more wild in nature, the pig pen height should be 1.2-1.5 m, and the door is best made of steel bars as an iron door. They tolerate coarse feed, and feed sources are wide. The feed is mainly green grass, tree roots, sweet potatoes, and straw, with a small amount of ordinary domestic pig feed. Wild boars have strong adaptability and are extremely convenient to transport. Farms have cages ready and are responsible for packaging. They can be shipped by car, train, or plane, and can be safely transported within 10 days by feeding only green grass along the way. Pay attention to disinfection at ordinary times.

Current status of wild boar populations

Europe

In recent centuries, the range of wild boars has been greatly reduced due to human hunting. They may have disappeared from the UK in the 13th century; by 1610 it was confirmed that no wild boars survived in northern England. King James I of England tried to reintroduce wild boars to some national parks, but failed due to poaching. Since 1700, wild boars have no longer appeared in the UK.

The last wild boar in Denmark was shot in the early 19th century, and they completely disappeared in the 1900s in Germany, Austria, Italy, Tunisia, and Sudan. They have disappeared in most parts of Russia, especially in areas west of the Altai Mountains. However, there are still many wild boars in France, and there are signs of growth.

After the 1950s, wild boars in Europe and Central Asia began to rebound: in 1960 wild boars were found in the outskirts of St. Petersburg and Moscow; in 1970 they appeared again in Denmark and Sweden, possibly having escaped from zoos; in the 1980s, because of the Chernobyl nuclear accident, the evacuation zone around the power plant gradually became living space for wild boars; in 1990 wild boars migrated again to northern Italy. In addition, in the UK a large number of wild boars also escaped from cages and grew in the wild, and their numbers are rising.

Spain captured a total of 4205 wild boars between October 2013 and February 2014, and captured 4387 in 2014-****. If live-captured wild boars are in relatively good health, they are usually sent to hunting grounds and forest areas far from residential areas.

Australia

Wild boars in Australia were brought into Australia by some European immigrants in the 18th century. In order to increase food reserves, these immigrants released some domestic pigs into the forests and scrub. Due to changes in the natural environment and lifestyle, domestic pigs gradually grew larger and developed bristles, becoming wild boars. At present, wild boars are distributed in all states along the eastern coast of Australia. Areas such as northern Queensland and the northern Northern Territory have year-round warm and humid climates and relatively abundant food. In addition, with almost no natural enemies, wild boars can be said to live a “free and happy” life. Statistics show that in recent years the number of wild boars in Australia has even exceeded the number of residents in the country. Australia's environment department believes that the wild boar overpopulation has already caused multiple threats, with agriculture and animal husbandry bearing the brunt. Wild boars are omnivorous animals with large appetites. Herds of wild boars often “invade” farms and ranches, gnawing on crops such as wheat, barley, sugarcane, apples, and watermelons. Some lambs on ranches have also become prey for wild boars. Wild boars also like to root in the soil and turn over mud, causing vegetation damage over large areas of land. Wild boars are also very fierce and often use wild animals as a food source, threatening the survival of endangered organisms and destroying the local ecological balance. A report released by Australia's federal environment department shows that predation by wild boars has already threatened the survival of 16 endangered species. At the same time, due to wild boar activities such as rooting in mud, trampling, rolling, and rubbing against trees, problems such as water source pollution and land degradation cannot be ignored. In addition, bacteria, viruses, and parasites carried by wild boars can spread diseases and pose a threat to the health of humans and other animals. As early as 2001, Australia listed wild boar overpopulation as an ecological environmental threat. The government also specially formulated opinions in 2013 on reducing the harm of wild boars in order to control their numbers.

China

China's "Zhejiang Province Terrestrial Wildlife Resources Survey Report" shows that in 10 cities in Zhejiang including Hangzhou, Quzhou, and Wenzhou, wild boars have repeatedly destroyed fields and injured people. Strengthened wildlife protection has gradually increased the number of wild boars, while wild large carnivores such as tigers, wolves, and leopards have gradually disappeared, and wild boars have lost their natural enemies. According to statistics, in 2000 there were about 29,000 wild boars in the whole province of Zhejiang, while in 2006 there were more than 100,000——that is, within 6 years, the number of wild boars increased by 2 times. Many remote mountainous areas have been completely “captured” by wild boars, and wild boars have even extended their reach into villages.

In Hong Kong, China, due to abundant food and water sources, plus very little hunting, wild boars have grown quite quickly and even often enter human living environments.

Artificial domestication of wild boars

For artificial domestication of wild boars, it is generally best to start domestication with small wild boars of 5-15 kg, as small wild boars are highly plastic and easy to domesticate. In the just-captured stage, purebred wild boars are timid and suspicious, highly alert, and relatively fierce in temperament, so the site should be kept quiet. After about half a month, some wild boars gradually adapt to the environment and become bolder. When the keepers feed them, they first make a fixed sound before feeding. Usually, by following “small amounts and more meals,” and making the same sound each time, the wild boars form a conditioned reflex, develop a sense of security, no longer fear people, and do not attack people. In order to accelerate their artificial domestication, for newly captured purebred wild boars, they can also be placed into pens of domestic pigs or special wild boars at a 1:1 ratio of the opposite sex. Because wild boars and domestic pigs have strong affinity and do not bite each other, they easily form a group. Led by domestic pigs or special wild boars, they can quickly eat boldly, and their growth rate also speeds up. At the same time, for bold male wild boars, one can gently scratch them first with a bamboo pole, and then scratch them with the hand without startling them. In this way, they can be considered completely domesticated.

Feed formulation for wild boars

Wild boar meat, with its characteristics of low fat, high nutritional value, and rich gamey flavor, has gradually become a substitute for domestic pork and a new type of green health food. Special wild boars eat less, and generally feeding twice a day is enough. They like raw food and have omnivorous feeding habits. Various weeds, vegetable leaves, plant rhizomes, and crop straw can all be used as feed. Wild boars especially like green feed, which can account for more than 50% of the daily ration, and a small amount of concentrated feed is enough to raise robust wild boars.

In the past, when wild boars were not yet protected, everyone went to hunt and kill them. Now that wild boars are protected, they have gradually increased. Artificial domestication of wild boars should start from a young age. They themselves like to eat omnivorous food, so their feed should also be diversified. In this way, their meat will be not much different from that of wild wild boars.

Chinese herbal medicine has a very long history. In ancient China, these plants and some animal internal organs and bones were mainly used to compose medicines that could cure human bodily diseases. Although Chinese herbal medicines have good medicinal value, the dosage of Chinese herbal medicines is also something to pay attention to. As the saying goes, medicine is three parts poison, so when using Chinese herbal medicines, one must pay attention to following the doctor's instructions.

The main source of Chinese herbal medicines relies on manual harvesting. Generally, wild Chinese herbal medicines have much better medicinal power than cultivated herbs. Yunnan is a place where Chinese herbal medicines grow, and there are rich herbal resources there. For common ones, we will give a brief introduction:

Murraya paniculata

Murraya paniculata is a common herbal medicine that itself has very high medicinal value. Murraya paniculata has the functions of promoting blood circulation and relieving pain, reducing swelling and detoxifying. For some bruises and injuries, we can apply crushed Murraya paniculata leaves to the injured area, which can have a certain effect.

Holboellia latifolia

Holboellia latifolia is a plant with great medicinal value and is used by many people in clinical medicine. Holboellia latifolia has medicines for treating edema, rheumatic arthralgia, bruises and injuries, and insufficient lactation. Its main usage is decocted in water for oral administration.

Camellia

Camellia is a common plant of ours, mostly used by people for planting in courtyards for appreciation. In fact, it is a plant with medicinal value. Camellia can mainly be used for stopping bleeding, for symptoms such as vomiting blood, metrorrhagia, and external bleeding.

Saxifraga stolonifera

Saxifraga stolonifera is mainly distributed in the southwestern region. The medicinal value of this plant is mainly reflected in its ability to treat boils, measles, cough, bronchitis, vomiting blood, venomous snake bites, and skin ulceration. It is widely used in life. For external injuries, this plant is crushed and applied externally; for internal injuries, it is decocted and taken.

Gardenia jasminoides

Gardenia jasminoides is mainly used medicinally by collecting the fruit, but its leaves and roots also have medicinal value. Gardenia jasminoides can mainly treat insomnia, vomiting blood, blood in urine, sprain swelling and pain, etc., but attention should be paid to the dosage, as an inappropriate dosage can cause poisoning.
