摘　　要：在大田条件下,研究了大垄三行密植对花生种植密度、叶片叶绿素含量、叶面积指数及主要经济性状的影响。结果表明,大垄三行密植较传统种植缩小了行距,扩大了株距,增加了种植密度,使植株群体根系分布均匀;由此引起叶绿素含量维持时间相对较长,叶面积指数增大;有利于干物质积累。虽然单株结果数、单株生产力、百果重、百仁重略有降低,但实收株数较多,大垄三行密植较传统种植增产34.9%,具有在大田生产中推广的潜力。Under field conditions,effects of big ridge cultivation ,Chl content in seedling,leaf area index and yield components.The results showed that the big ridge with three lines cultivation reduced the row spacing, expanded plant spacing,increased the plant densityand make plant root population distribution than the tradi-tional planting mode,These caused chlorophyll content to maintain a relatively long time,increased the accu-mulation of dry matter,larger leaf area index,higher yield.Although fruit number per plant,yield per plant, fruit weight and seed weight were slightly low,but the plants was more,so the yield of big ridge cultivation in-crease about 37.1 % than traditional planting model,significantly.
