Abstract
Mikania micrantha HBK now is one of important foreign invasive plants. Plants in the island＆apos;s low-lying areas of central and southern orchards, woodland and hillside widespread growth. Very strong ability to adapt vine of Mikania micrantha produced vast amount of seed and the advantage of rapid growth, rapid proliferation of offspring produced and the wound hosts on the canopy, Conducted into the light and hinder the role of host. Leading to crop production volume of light were reduced, causing the host dead.Big flower Bidens (Bidens pilosa L. var. Radiata (Bl.) Sherff) of the hazard, also the formation of an elevation of 2000 m following a very serious ecological problems. Survival of native plants severely squeezed.Therefore, this project intends to marketed goods, select the benzoic acid (Bezoic acid), organic phosphorus (Organophosphorus compounds), Jacqueline (Quinoline) and microphone sit (Imidazole) and other compounds as the test drug.From the Lauraceae in the camphor tree (Cinnamomum camphora), or in the Myrtaceae (Eucalyptus camaldulensis) and other species, to take leaves, bark and other items. Fresh leaf and bark materials, oil extraction, hot water extract and methanol extract and so on, analyze the composition of crude, and the screening and assessment of the principal component of the prevention and control of plant activity.According to germination inhibition, pot tests and test plots, the results show screening features. The main biologically active substances will be determined and the active ingredients of separation parts too. This will be the effective deployment of a natural inhibitor compound. That is exclusive with the matrix material in order to control its release rate in order to develop plants as a natural inhibitor of the fundamental basis for purpose.
