Ecological Control Methods of Forest Harmful Plants in South China

Abstract

The invention discloses an ecological control method for south Chinese forest harmful plants. The ecological control method includes the steps: firstly, removing withered trees and shrubs and invasive plants; secondly, planting several aboriginal plants among heteropanax fragrans, olive, hackberry, radix fici hirtae, ivy tree barks, demissa michelia figo, henryi and burmann cinnamon barks or litsea glutinosa in a region without the invasive plants, and reconstructing vegetation; timely removing not survived reconstructed vegetation seedlings and reseeding after vegetation reconstruction. The method particularly has remarkable effects for restoration and vegetation reconstruction of forests invaded by the harmful plants including one or a plurality of pueraria phaseoloides, merremia umbellata, jasminum elongatum, piper sarmentosum or rubus alceaefolius poir, re-growth of the harmful plants can be suppressed once for all, harm of the invasive plants can be eliminated, economic benefits of reconstructed vegetation tree species can be achieved, and the method is of great and far-reaching significance for sustainable development of the south Chinese forests and improvement of the economic benefits.

Description

technical field [0001] The invention belongs to the technical field of invasive plant ecological control. More specifically, it relates to ecological control methods of harmful plants in South China forests. Background technique [0002] Invasive plants refer to certain plants that are accidentally or intentionally introduced outside the normal distribution area, colonize and endanger the biodiversity, ecological environment, habitat and human health or living environment of the invaded area. Invasive plants have become one of the most serious environmental problems worldwide. Our country is seriously harmed by invasive plants, and the annual loss caused by invasive plants is as high as 20 billion. Invasive plants spread rapidly in the southeastern provinces, especially Guangdong and Fujian, seriously endangering the tropical and subtropical forest ecosystems in my country. They affect the photosynthesis of trees by winding, strangling or covering the canopy of local vege...

AI Technical Summary

Problems solved by technology

[0003] At present, manual and mechanical removal and application of herbicides are mostly used for forest invasive plants, but only removal of harmful plants often leads to recurrence of invasive plants or outbreak of new invasive plants

Moreover, due to the complexity of the ecological control of invasive plants, different plants have very complex and subtle interrelationships. Forests in different regions, different invasive plants, control and restoration methods are not repeatable, and the reference is very low.
