Plant population effect on growth factors and yield of plantain in an Andisol from Quindio, Colombia (1993). 表1 哥伦比亚Quindio 火山灰土上种植密度对大蕉生长因素及产量的影响(1993) Table 1.
The vital threshold is crossed when the plant population shrinks to the point that the recycled rainfall becomes too meager to sustain the population. 当植物的群落萎缩到了极点，以致循环降雨过少，难以维系群落的生存时，维持生命的门槛就被跨越了。
High plant population increases production cycle length and reduces bunch weight, but these factors are compensated by far, by the higher number of bunches per unit area. 密植加长生产周期并降低蕉串的重量，但这些可以通过获得较高的单位面积蕉串数量而完全得到补偿。
