| 摘 要： | 为探究老挝丰沙里省小粒咖啡园杂草的发生危害情况,笔者于2016-2017年采用倒"W"形9点取样法对老挝丰沙里省6县小粒咖啡园进行调查研究。确定了该地区小粒咖啡园杂草有79种,隶属于23科66属,其中相对多度在10%以上的有11种杂草。白茅、粽叶芦、飞机草、胜红蓟、马唐、蕨、牛筋草、鬼针草、小飞蓬、藜和铺地黍是构成老挝丰沙里省小粒咖啡园杂草群落的优势杂草。研究结果将为老挝丰沙里省小粒咖啡园的杂草防控提供重要参考。

| Abstract: | A survey was conducted to determine weeds associated with the Arabica coffee gardens in six counties of Phongsail,Laos,using a "W" 9-point sampling method from 2016 to 2017. There were 79 weed species in the Arabica coffee gardens,belonging to 23 families and 66 genera;the relative abundance of 11 species was above 10%. Imperata cylindrica,Thysanolaena latifolia,Eupatorium odoratum,Ageratum conyzoides,Draba matangensis,Pteridium aquilinum,Eleusine indica,Bidens pilosa,Conyza canadensis,Chenopodium album and Panicum repens were the dominant weeds in the weed community of Arabica coffee gardens in Phongsail,Laos. This study provides an important reference for the prevention and control of weeds in the Arabica coffee gardens in Phongsail,Laos. |
