| 摘 要： | 磷元素在马铃薯植株体内的流动性较大,磷营养水平与块茎膨大密切相关,块茎是磷素的最终贮存库。在块茎增长初期,叶片、地上茎和块茎中的磷素浓度均为一生中的最高值,此时是马铃薯对磷需求最多的时期,块茎形成后,则大量的磷(P2O5)向块茎转移。马铃薯对磷素(P2O5)吸收速率较低。在整个生育期内吸收速率呈单峰曲线变化,峰值出现在块茎增长期。

THE PATTERNS OF PHOSPHORUS ABSORPTION, ACCUMULATION AND DISTRIBUTION IN POTATO |
| |
| Abstract: | Phosphorus was easy to flow in potato plant and there was close correlation between phosphorus level and tuber bulking. Tuber is the final storeroom. Phosphorus concentration in leaves, above ground stems and tubers reached their maximal values in early tuber bulking stage when potato needed phosphorus most. Most of the phosphorus began to transfer into tubers after tuber formation. Phosphorus absorption rate was low and it was a curve with single peak, which appeared at the stage of tuber bulking. |
