摘要: 为了提高磷肥利用率和棉花产量,在田间试验条件下研究了两种施磷方式对棉花根系活力和产量的影响。结果表明:在相同施磷量条件下,磷肥条施与传统施肥方式相比较棉花根系活力增加1.7倍,籽棉产量增加14.5%,磷肥农学利用率增加38.0%,磷肥偏生产力增加14.5%。通过试验研究得出磷肥条施不仅可以增加棉花根系活力和产量,而且还可以提高磷肥利用率。

Abstract: In order to improve the efficiency of phosphorous fertilizer and cotton yield. The root activity and seed yield with banding phosphorus as seed manure in cotton were studied in the field. The results showed compared with farmer applying fertilizer manner, the root activity and yield increased by 1.7 times and 14.5% respectively, Agronomic efficiency of phosphate fertilizer and phosphate fertilizer partial productivity increased by 38.0% and 14.5% respectively. This study showed that banding phosphorus as seed manure not only increased the root activity and cotton yield, but also increased the efficiency of phosphorous fertilizer.
