Truffles are stem fungi that grow in soil and attach to tree roots. Truffles generally grow under trees such as pine, poplar, oak and oak. Truffles need to rely on the relationship between roots to obtain nutrition, so they can't live independently. Truffles have high requirements on the growth environment, like alkalinity and cannot carry out photosynthesis. Truffles absorb more nutrients. If it grows under the root, it will not grow under the root in a short time.

First, the characteristics of truffle growth environment

1. Truffles are very picky about the growing environment. Truffles will not grow if the soil pH and water environment change slightly.

2. Truffles can't carry out photosynthesis, but can only attach to the roots of trees, and exchange nutrients needed for growth with the help of the * * * relationship between trees, so they can't live independently.

3. Truffles can't be planted in order. After truffles grow under the roots, soil nutrients will be completely absorbed, and no other plants will grow under the roots in a short time. After truffles are dug out, the soil needs to be sold back, otherwise the growing environment will be destroyed and truffles will not grow again.

4. Truffles prefer alkaline soil, and high-quality truffles are mainly produced in calcareous terrain.

Second, what is truffle?

1. Truffles are stem fungi that grow in soil and attach to tree roots. Truffle is a general term for mushrooms. Truffles generally grow under the roots of pine, poplar, oak and oak, and are mainly distributed in Italian, French, China, New Zealand and other countries.

2. Truffles have a special smell. They are delicious food rich in protein and amino acids. They can't be cultivated artificially, and the yield is scarce. Truffles are called in Europe? What are the three great foods in the world? One.

3. The fruiting body of truffles is huge, including small truffles such as walnuts and big truffles such as fists. Truffles are white and uniform in texture in infancy. When they mature, truffles are dark black and have a light marble texture.

4. The ascocarp of truffle is spherical, brown or brownish, with polygonal warts on the surface and depressions on the top.

5. The growth cycle of truffles is only one year, and the size has nothing to do with age. It grows with the change of four grades. Generally, black truffles will mature in 65438+February.

6. Generally, the maturity of truffles is from June 1 1 to March of the following year, and the best picking season is from February 65438 to March of the following year.

7.2 1 century, most of the soil was sprayed with pesticides and mechanized farming, which led to unsatisfactory growth environment of truffles, and the yield of truffles decreased accordingly.
