本试验研究了多元复种条件下杂交棉种植密度对皮棉产量、套种作物产量和棉田总产值的影响，并根据经济学原理得出杂交棉多元复种的最适种植密度为１９４８株／亩。
In this study, the effect of planting density of hybrid cotton on lint yield, intercropping crop yield and total cotton output was studied under multivariate multiple cropping conditions. According to economic principle, the optimum planting density of hybrid multivariate hybrid cotton was 1948 plants / acre.
