通过田间试验，研究了磷肥不同用量对棉花干物质积累、产量及氮磷钾吸收、积累、分配的影响。结果表明：增施磷肥可以增加棉花干物质量、产量和氮磷钾素的积累量，但过量施用磷肥增加效果并不明显。当磷肥用量（P2O5）为 75 ～ 150 kg·hm-2 时，对棉花干物质积累、产量和棉花各器官氮磷钾素的积累有明显的促进作用，棉花花铃期干物质积累和棉花各器官氮磷钾的积累量分别比对照平均提高了 24.6%、30.7%、55.9% 和 36.4%；吐絮期干物质积累、产量和棉花各器官氮磷钾的积累量分别比对照平均提高了 33.4%、39.9%、49.1%、47.7% 和 53.0%。
Abstract
According to the field experiment, we studied the effect of different phosphorus fertilizer rate on dry matter accumulation, yield, absorption and distribution of nitrogen, phosphorous, potassium of cotton. Results suggested that increase the phosphorus fertilizer rate can enhance the dry matter accumulation, yield, absorption and distribution of nitrogen, phosphorous, and potassium of cotton, compared with the treatment of P0, but the more is not obviously, and there is a obviously significant improvement effect on dry matter accumulation, yield, accumulation of nitrogen, phosphorous, potassium of cotton while P2O5 was applied at 75～150 kg·hm-2. Compared with the treatment of P0, the average of dry matter accumulation, accumulation of nitrogen, phosphorous, and potassium of cotton in flower and boll stage increased by 24.6%,30.7%, 55.9%, 36.4%,respectively; the average of dry matter accumulation, yield, accumulation of nitrogen, phosphorous, and potassium of cotton in opening stage increased by 33.4%,39.9%,49.1%, 47.7%, 53.0%,respectively.
