为了合理利用与有效控制柑桔园杂草,于2005—2006年在湖南省柑桔园进行了大面积普查和抽样调查,基本摸清了湖南柑桔园的杂草种类、分布、群落结构和优势种群。共调查到41科136种,其中以禾本科、菊科和苋科杂草为主的3科13种杂草为优势种群。对柑桔园杂草的综合治理与合理利用途径进行了探讨。
The weed types in citrus orchards and their distribution in Hunan Province were studied in 2005-2006, and 136 weeds which belong to 41 families were identified. The community composition and dominant population of weeds were also analyzed. According to the quantity,density, frequency, and the degree of potential harm to citrus tree, 13 weeds which belong to Family Poaceae, Asteraceae and Amaranthaceae were determined as dominant population.
