高产棉花各生育期段的干物质分配规律 :苗期干物质主要积累在叶片 ,蕾期后叶、茎、根所占干重的比例逐渐降低 ,干物质集中于蕾铃。施硫肥可增加棉花植株对氮素的吸收 ,使皮棉产量增加6.5 %～ 1 5 .0 %。
Dry matter distribution pattern of high-yielding cotton at each growth stage: Dry matter mainly accumulated in the leaves at seedling stage, the proportion of dry matter in leaves, stems and roots gradually decreased after budding stage, and dry matter was concentrated in buds. Application of sulfur fertilizer can increase cotton plant nitrogen absorption, so that lint yield increased 6.5% ~ 15.0%.
