The environment in Benxi is not suitable for the growth of truffles. Truffles have strict requirements on their growth environment, such as altitude, temperature, humidity, sunshine, oxygen and so on.
With a little change, it won't grow up. There are only two truffles made in China: Yunnan and Sichuan.
The growth of truffle needs special environment, and the main tree species in its growth area is Pinus yunnanensis, which grows at the fibrous roots of pine trees. Truffles only grow where pine pollen can fly and cover them.
Moreover, the soil should contain copper and iron, which are necessary components for truffle growth; In addition, the changes of topography, temperature and humidity and the distribution of sunlight will also affect the growth of truffles.
The environment in Liaoning is not suitable for the growth of truffles. Liaoning is a hilly and low mountain area in Guanzhong Plain, Shaanxi Province, with a warm temperate semi-humid and semi-arid monsoon climate. The annual average temperature is 1 1 ~ 14℃, and the annual precipitation is 500 ~ 700 mm, more than half of which is concentrated in summer and dry in winter. Vegetation is dominated by mesophyte and xerophyte forest shrubs.
The leaching degree is not very strong, and a small amount of calcium carbonate precipitates. The soil is neutral and alkaline, with more minerals and organic matter accumulated, thicker humus layer and higher fertility.
Black truffle:
Black truffle (Tuber melanosporum in Latin and perigord truffle in English), also known as truffle, is a kind of wild edible fungus growing underground, with uneven appearance.
The maturity of black truffles is usually from June 1 1 to March of the following year, and the best season is usually from February 1 to March of the following year. Truffle collectors are called truffle hunters.
Every truffle hunter has a family treasure map, which records the location, time and size of truffles that his parents once found. The process of finding truffles is very interesting, and hunters in different countries use different methods.
Truffles are very picky about the growing environment. As long as the pH of sunlight, water or soil changes slightly, they cannot grow. Truffles are the only delicious food in the world that can't be planted in an orderly way.
Truffles grow under a tree, but another tree that looks exactly the same can't, and people don't know why.
Unlike common fungi such as mushrooms, the spores of truffles are not spread by wind, but by animals that eat truffles. Truffles mainly grow under pine, oak, hazel, beech and orange trees.
This is because truffles can't carry out photosynthesis and live independently, and they must rely on the * * * relationship with some roots to obtain nutrients.
