Method for controlling foreign spartina alterniflora loisel by biological substitution

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 ...
