紫茎泽兰根区土壤酚酸类物质组成及其对土传病菌的影响

The allelochemicals released by Eupatorium adenophorum roots is an important factor inducing the changes of the weed soil environment,which provides favorable conditions for the successful invasion of the weed.By using GC/MS technique,the components and their relative contents of phenolic allelochemicals in aphid-infested and non-infested E.adenophorum root zone soils were analyzed,with unplanted soil as the control.Less difference was observed in the components of phenolic allelochemicals among the test so...
