摘要: "一元多生态位"群体是指由同一个物种(品种)构成,生态元具有不同时间生态位、空间生态位、营养生态位、温度生态位或者水分生态位等.其特征为,群体培育具有目标性,种群组成具有一元性,冠层结构具有多层性,群体形成过程具有人工调控性,群体建立过程具有简单性,所形成的群体各生态元具有特定的生态位宽度、生态位重叠与生态位分离.从产量构成来看,作物"一元多生态位"群体具有群体生产能力的高效性和单株生产能力的差异性特征.

关键词: 一元多生态位, 生态位宽度, 生态位重叠, 棉花

Abstract: The multiple ecological niche of one-species (variety) (MENOS) population is formed by one species (variety),but the ecological units have different temporal,spatial,nutritional,temperature,or water ecological niche.The formation of MENOS population is characterized by its specific object,one species (variety),multiple layer canopy,human being's active adjustment,specific niche breadth,and overlap and separation of ecological units.This paper analyzed the characteristics of the super high yield cotton population with dual ecological niche of one-species (variety) (DENOS).As for the yield components,MENOS has the characteristics of high yield canopy and different yield plants.

Key words: Multiple ecological niche of one-species (variety) (MENOS), Niche breadth, Niche overlap, Cotton
