澳大利亚农田杂草分布危害研究

STUDIES ON FIELD WEED DISTRIBUTION AND INFESTATION IN AUSTRALIA

飞机草（Ｅｕｐａｔｏｒｉａｏｄｏｒａｔｅ）．龙爪茅（Ｄａｃｔｙｌｏｃｌｉｕｎｔｎｔａｅｇｙｐｔｉｕｍ），含羞草（Ｍｉｍｏｓａｐｕｄｉｃａ）等热带杂草和种草（Ｅｃｈｉｎｏｃｈｌｏａｃｒｕｓｇａｌｌｉ），马唐（Ｄｉｇｉｔａｒｉａｓａｎｇｕｉｎａｌｉｓ）马齿苋（Ｐｏｒｔｕｌａｃａｏｌｅｒａｃｅａ），野燕麦（Ａｖｅｎａｆａｔｕａ）等世界性杂草的分布危害在澳洲和中国相似；鼠茅（Ｖｕｌｐｉａｍｙｒｏｕｓ），瑞士黑麦（Ｌｏｌｕｍｒｉｇｉｄｕｍ），欧洲蓝蓟（Ｅｃｈｉｕｍｐｌｕｎｔａｇｉｎｅｕｍ）等分布危害和欧洲相似；斗蓬草（Ａｒｃｔｏｔｈｅａｃａｃａｌｅｎｄｕｌａ），铁梗草（Ａｍｓｉｎｃｋｉａｃａｌｙｃｉｎｅ）的分布危害和南非、南美洲相似。

The distribution and infestation of tropical weeds;such asEupatorium odorate; Dactyloctium aegytium; Mimosa pudica; Echinochloa crusgalli;Digitaria sanguinalis; Porlulaca oleracea and cosmopolitan weeds such as Avenafatua in tropical and temperate zones of Australia are the same as the case forChina.The distribution and infestation of most troublesome weeds such as Vulpiamyrous;Lolium rigidum;Echium plantgineum in cereal crop fields in Australia areparallel to the case for England and Mediterranean area. While the distribution andinfestation of some weeds such as Arctotheca calendula;Ansinckia calycine in theSouth Australia are similar to the case for South Africa and America;but not forChina.
