摘要
通过田间试验与研究分析，建立了看麦娘和小麦密度与小麦产量的关系模型及由于竞争而引起的小麦产量损失模型．较准确地描述了看麦娘和小麦的竞争关系，预测由看麦娘竞争引起的小麦产量损失，模型参数具有实际的生物学意义．这对研究看麦娘的生态经济阈值，制定有效的看麦娘管理方案，建立高效的农业生态系统，具有重要的意义．
The competitive effects of varing Alopecurus aequalis and wheat density were modelled based on the field experiment and mathmatical analysis. The models are capable of describing the competitive relationship between Alopecurus aequalis and wheat, and predicting the yield loss. The parameters are biologically meaningful. These models are worthwhile for the reasearch of eco economics threshold for effective weeds management and for the establishment of effective agro ecosystems .
