Study On Bio-ecologiacal Characteristics And The Integrated Control Of Solidago Canadensis L.

Solidago canadensis L. is introduced virginly and initially as the flowers, and then the ease grows the field, become the weeds . Because it has extremely strong reproduction and occupies the ability of the space fast, can suppress the growth of other plants , it is apt to form and grow the advantage only, destroy bio-diversity of invading the ground and ecological balance, and has constituted a threat to agricultural production.This research purport is on the basis of the law happens in one to grasp Solidago canadensis L., find out its bio-ecologiacal characteristics, and establish the system of integrated control arises technologicallying. The main content is as follows:First, through to that biological investigation and composition of analyse about Solidago canadensis L.Second, through launching the investigation to insect kind that take in Solidago canadensis L..Third, the research of the allelopathy on Solidago canadensis L.Fourth, study on the plant tissue culture and plantlet regeneration of Solidago canadensis L.Fifth, test and prevent and kill off experience with production through summarizing the drug in recent years, but one different from spot happens according to it , choose different physics and living beings to prevent and kill off the means.Combine chemistry and prevent and kill off the method, establish the system of integrated control.
