Why is the “cotton head” difficult to find this year, and Aunt Gao can’t speak.

A reporter from Qianjiang Evening News invited a “wild vegetable” expert. Professor Li Genyou from Zhejiang Agriculture and Forestry University and Yang College helped to analyze the original committee.

“Rats and grass are seen in the south. They like the wet environment. Generally, fields, rivers, and hillside and grass are available, but the forest is too dark and generally does not grow. It is too humid and it is not good.” Roots say.

According to meteorological analysis, the rainwater last winter was one -third more than the same period of previous years. Li Genyou said that because mouse grass is a low -type plants, the continuous rainy rain in winter leads to too much water in the ground, which has a large impact on the plants such as mouse grass. Growth.

Do you find the grass grass in the place where artificial greening. Is this experience summarized by Aunt Gao?

“Actually, for Zhejiang local plants such as rats and grass, artificial lawn grass is also considered to be foreign species, and this grass has a strong occupation.” Li Genyou said.

Li Genyou said that many rural greening now is also very good. It will plant lawns in the naked places on the roadside and riverside, but once the lawn is planted, those low native plants have no room for survival. This is also a major reason why plants like rats are facing a crisis of survival.

Frequent walking in rural areas, there is another concern for agricultural and forestry experts.

“The slag of the construction site in the city falls to the countryside.” Li Gen lamented that the surface soil layer of the countryside was like a natural museum, which preserved a large number of local biological resources. When the thick duster covers, it is destructive for these resources. Therefore, the dregs should still be rationalized and utilized, and cannot be dumped towards the countryside at will.
