Description

Technical Field

[0002] Spartina alterniflora is a perennial herb of the Poaceae family and the genus Spartina. The underground part consists of short and thin fibrous roots and rhizomes. It has a well-developed root system that can be distributed up to 100 cm deep in the ground. It grows in the intertidal zone. The plant is resistant to salt and flooding, and is resistant to wind and waves. Its seeds can be spread by wind and waves. The root system is distributed in the beach soil up to 60 cm deep. A single plant can reproduce dozens or even hundreds of plants in a year. It is native to the Atlantic coast of North America. In the late 1970s, Spartina alterniflora was rapidly introduced in my country's vast estuaries and coastal mudflats, achieving certain ecological and economic benefits, but it also brought a series of hazards.

In this process, the limit rod 116 will cooperate with the limit groove 113 to keep the push rod 14 stable. Finally, the rotating head 115 can be rotated to take out the soil sample and complete the soil sampling work.
