摘　　要：研究了奶花芸豆4种不同群体条件下,叶绿素含量、叶面积指数、单位面积干物质积累及产量的变化规律。研究结果表明随着密度增大,单位叶面积叶绿素含量降低;叶面积指数增大,但密度过大则叶面积指数高值期持续时间较短;干物质积累量和产量在一定密度范围内随密度的增加而增加,但密度过大,干物质积累量和产量反而下降。Regulation of chlorophyll content, LAI,dry matter accumulation and yields under four different populations in Phaseolus coccineus L. was studied in this research. The result of this research showed that the chlorophyll content reduce along with the increasing of planting density. LAI increase along with the increasing of planting density. The high numerical value period became short, if the LAI was too big. The dry matter accumulation and yields increase along with the increasing of planting density within some certain density range. If the planting density become too big, the dry matter accumulation and yields will become lower on the contrary.
