广西农业生态系统外来入侵杂草发生与危害现状分析
Occurrence and damage of alien invasive weeds in Guangxi agricultural ecosystem
摘要
Abstract
[Objective]The study was performed to investigate the occurrence and damage of alien invasive weeds in Guangxi agricultural ecosystem in order to provide references for their risk assessment and further prevention and control.[Method] Based on field investigations and related literatures,systematic study was conducted from October 2011 to September 2012 to investigate variety,distribution,habitat and damage degree of invasive weeds in rice,sugarcane,cassava,mulberry,orchard,vegetable and other crop fields in 80 counties and 14 cities of Guangxi.[Result]A total of 101 species of invasive plants belonging to 74 genus and 27 families were identified in Guangxi farmlands.Amongst them,Compositae was the most invasiveweeds,which was consisted of 25 species and it was followed by Gramineae (17 species),Amaranthaceae (8 species),Solanaceae (7 species),Leguminosae (6 species),Convolvulaceae (5 species) and Euphorbiaceae (5 species).There were 88 species of herb,accounting for 87.13％ of the total species.A total of 67 kinds of weeds scattered around Guangxi,which made up 87.13％.Regarding damaging level,15 kinds were severe alien invasive weeds and 22 varieties were moderate alien invasive weeds.[Conclusion]Alien invasive weeds in Guangxi farmlands involved multi species and huge quantities,which have caused serious harm to agricultural economy.Monitor setup,risk assessment,prevention and control system of alien invade species were efficient ways for defending against the alien invasive weeds.关键词
