摘要
2016—2017年对老挝丰沙里省小粒咖啡园杂草开展调查,发现杂草23科66属79种,其中,菊科、禾本科为小粒咖啡园优势杂草种群,占杂草总种类的39.24%;双子叶杂草为小粒咖啡园优势杂草种群,占杂草总种数的72.15%,由于耕作方式和人为干扰,小粒咖啡园多年生物种占物种总种数的51.90%。
Surveys were made of the weeds in the Arabica coffee plantations in Ph?ngsali province, Laos in 2016 and 2017. These surveys showed that there were 79 species, 66 genera and 23 families in the weeds in the Arabica coffee plantations in this province, of which Compositae and Gramineae were dominant weed populations, accounting for 39.24% of the total weed species. Dicotyledon weeds were dominant weed populations in the Arabica coffee plantations, accounting for 72.15% of the total number of weeds. Due to farming practices and human disturbance, perennial species of the weeds accounted for 51.90% of the total species in the Arabica coffee plantations.
