Embodiment Construction

[0022] 1. Micro-geomorphological changes: The tidal flat ecological engineering operation site is selected and the operation can be carried out after the planning is approved. Carry out cofferdam work on the sea surface at the selected work site, dig ditches on both sides to collect soil, pile the soil in the middle, and compact it to make a simple dam with a height of 2 meters and a width of 2 to 3 meters on the top surface, and the surface of the embankment will become a road , The embankment is used to prevent seawater from entering the cofferdam; the trenches in the cofferdam are used to store fresh water and divert ditches, and salty-freshwater fish can be stocked in the ditches as by-products.

[0023] 2. Straw recoating: After the cofferdam is completed, remove the plant residues of Spartina alterniflora, reeds and other plants on the surface of the cofferdam. The dual function of eliminating disease-causing pests and germs prepares good conditions for the growth of ree...

Abstract

The present invention belongs to the field of ecological engineering technology, and provides a method for controlling breeding potential of adventitious species huhuami waterweed. Said method can overcome all the defects or existent control methods and can obtain the optimization and unification of economic benefits, ecological benefits and social benefits.

Description

1. Technical field [0001] The invention belongs to the technical field of ecological engineering. 2. Background technology [0002] Spartina aterniflora is native to the United States and is a perennial salt marsh plant that grows in the intertidal zone. The plant of Spartina alterniflora is strong and tall, and its root system is extremely developed. The ground height can generally reach 1.0-2.0m, and the root system can reach about 1.5m deep into the soil. The effect of greening the beach. At that time, my country's coastal areas were often hit by natural disasters such as storm surges and typhoons, and the economy, people's lives and property in coastal areas were greatly endangered. At the beginning of 1980, Spartina alterniflora was introduced into the coastal tidal flats of our country, and made great contributions in many aspects such as protecting beaches, promoting siltation and land formation, promoting economic development in coastal areas, improving ecological ...
