Analysis of the technology and management ofAzolla filiculoides and its various applications

The components of life are connected like a chain, andthis connection allows one to examine other factorswhile studying.Azolla filiculoides is an invasive speciesthat has grown in fish ponds, rice fields in northern Iranand Anzali International Wetland and has become anenvironmental problem.Azolla is a floating fern speciesthat occupies large levels of aquatic ecosystems.Excessive growth of this plant in lakes, ponds, wetlandsand ..., interferes with the use of water resources byhumans, adversely affects the quality of water andcreates ecological problems on other plant and animalspecies.Azolla was an uninvited guest who arrived inIran in 1984 to grow rice. The unique capabilities of thisplant made it uncontrollable and this plant grows widelyin the north of the country and is more widely known in the wetlands and rice fields as a problem of invasivehabitat and vegetation, Up to a useful plant. This fern reptile entered Iran without comprehensive research onmorphology and growth, and only to increase riceproduction. Due to the wide distribution of azolla, rapid growth and nitrogen fixation, it is necessary to controlthe growth and reproduction of this plant species bytaking appropriate management measures in addition topreventing disturbing the ecological balance of aquatic ecosystems of this plant for various purposes, Optimaluse.
