In agriculture, when it comes to diseases and insect disasters, farmers are really sad to die, and these pests and diseases will lead to a large reduction in the production of agricultural products and cause serious economic losses. However, there is a plant disease that is an exception, which is not only not annoying, but even undesirable, and the economic benefits of the products after the disease are even higher. This lesion occurs in corn, and the product of the lesion is what we know as black truffle.
The appearance of black truffle may not even be counted as its appearance, although it looks ugly, but its price is very expensive.
As long as you want a restaurant with black truffles, people think it may be to give a high-end restaurant. Black truffles are not only delicious, but also have high nutritional value and have certain medicinal value. High-end restaurants will add black truffles to the food to accompany the taste, and the black truffles themselves also treat blood deficiency, tiredness and thirst, and can also treat and prevent a series of gastrointestinal and liver problems. This is also the reason why black truffles are so popular in the market.
Recently, on a mountain in Haicheng, Liaoning Province, a large number of wild black truffles appeared, and it is said that a person can dig 20-30 pounds a day. In the local area, the price of black truffles is about 150 yuan a pound, and going up the mountain to dig up black truffles can be said to be easy to earn three or four thousand yuan a day, which is simply beautiful.
However, because people flock to the mountains to dig up black truffles, the local mountains have become potholed. In foreign countries, people use pigs or dogs to search, and after finding black truffles, they will cover the soil layer.
This disease that appears on corn has a more direct name, called "corn powdery mildew", this fungus likes to parasitize the surface, soil, disease residues, especially in dry and rainy places, this fungal spore has the greatest chance of survival. They only need dew at night to survive. During the development of corn, powdery mildew can be impregnated. Nevertheless, while digging up black truffles, people should not damage the local ecological environment.
Black truffles are better known because they are often used in high-end French restaurants, and the history of black truffles consumption in the West is 2,000 years, but in the recipes of Chinese, black truffles are not very high. In fact, China also found black truffles around 1990, the field survey team found a large number of black truffles in Yunnan, and Yunnan is also the province with the highest production of black truffles in China. Also because China's black truffle production has gone up, the global price of black truffle has declined.
Black truffles are a fungus that relies on the roots of trees for nutrients, and they have no ability to spread spores by themselves, relying on other animals to bring spores to other places. Black truffles generally grow and mature in winter, and wherever they mature, the surrounding land looks scorched black as if it had been burned by fire, and once the black truffles are excavated, the vegetation can quickly return to its original state.
Fungi themselves are not as capable of capturing the energy of sunlight as plants, and they themselves lack the ability to synthesize organic matter, so they must rely on humus to survive. So they all get nutrients in nature and are associated with other organisms.
The difference in the types of humus is very small, but black truffles are very sensitive to this. So the same location may have black truffles in one place and nothing in another place not far away. In addition, where black truffles have grown, it is more likely that they will continue to appear, so if the collector of black truffles has a better memory, the harvest will be more fruitful.
After all, the value of black truffles is so high, many people at home and abroad have tried to plant black truffles, but in the end they have no problem, because black truffles can not be artificially large-scale farming. The current black truffles are pure wild, and the problem is that the environment in which black truffles grow and mature is too complex for humans to simulate the same environment to cultivate. As we mentioned above, even if the difference in humus is very small, the slightest change can cause the black truffle to fail to grow.
