摘　　要：经调查表明 ,余庆县吴茱萸种植地发生杂草种类共有 2 2科 5 3种 ,其中主要杂草种类有 1 3种 ,以单子叶杂草占优势 ;杂草群落组成以单子叶杂草为优势种 ,阔叶杂草为亚优势种和配搭种组成 ;以定植第 1年和定植第 2年的吴茱萸种植地杂草发生危害较重 ,定植第 3年开始减轻 ;秋季比春季危害重。结合中药材GAP生产要求 ,提出了以农业防治为基础 ,生物防治为辅 。Based on the investigation in Evodia rutaecarpa planting areas, the results show that there are 53 species of weeds belonging to 22 families. There are 13 dominant weed species, and most of them are monocotyledon. For the weed population, the dominant species are monocotyledon, the broadleaf weeds and other species are secondary dominant species. The weed occurrences are mostly in the 1st and 2nd year after planting, and fewer after the 3rd year, and the damage in Autumn is higher than spring (season). According to the requirement of the GAP standard for the Chinese medicine, the fundamental measurement should be (agricultural) control, assisting with biological control, and taking hand-weeding in the right time.
