| 为了明确川麦冬Ophiopogon japonicus主产区的主要杂草种类、危害情况、分布特征与群落结构, 对川麦冬主产区杂草种群进行调查, 通过生态位与种间关系分析发现, 川麦冬主产区共有杂草16科34属40种, 其中主要杂草15种, 川麦冬主产区杂草群落种间整体呈不显著的负关联, 总体联结性较为松散, 处于不稳定状态, 确定香附子Cyperus rotundus、牛筋草Eleusine indica、马齿苋Portulaca oleracea、马唐Digitaria sanguinalis、荠Capsella bursa-pastoris、异型莎草Cyperus difformis、龙爪茅Dactyloctenium aegyptium与早熟禾Poa annua为重点防控杂草。通过典范对应分析(canonical correspondence analysis, CCA)发现, 川麦冬主产区杂草发生与分布主要受平均气温与平均湿度的影响。本研究为建立川麦冬田杂草综合防控体系提供依据。 |
| 英文摘要: |
| In order to clarify the main weed species, damage, distribution characteristics and community structure of Ophiopogon japonicus in the main producing areas of O.japonicus, the weed population in the main producing areas of O.japonicus was investigated. Through the analysis of ecological niche and interspecific relationship, it was found that there were 40 species of weeds belonging to 34 genera and 16 families in the main producing areas of O.japonicus, including 15 main weeds. The weed community in the main producing areas of O.japonicus showed no significant correlation between species, the overall connection was loose and in an unstable state. Cyperus rotundus, Eleusine indica, Portulaca oleracea, Digitaria sanguinalis, Capsella bursa-pastoris, Cyperus difformis, Dactyloctenium aegyptium and Poa annua were identified as key weeds for control. Through canonical correspondence analysis (CCA), it was found that the occurrence and distribution of weeds in the main producing areas of O.japonicus were mainly affected by average temperature and average humidity, which provided a basis for establishing a comprehensive weed control system in O.japonicus fields. |
