摘要: 以马铃薯品种下寨65为研究对象,测定不同氮磷钾处理下对格尔木地区马铃薯养分吸收量、氮磷钾肥料利用率以及产量的影响。结果表明,格尔木地区马铃薯种植氮肥利用率为38.6%,磷肥利用率为9.2%,钾肥利用率为52.3%;在施氮量为220.00 kg/hm2,施磷量为158.50 kg/hm2,施钾量为81.30 kg/hm2时产量相对较高。

Abstract: Taking potato variety Xiazhai 65 as the research object, the effects of nutrient absorption, nitrogen, phosphorus, potassium fertilizer utilization, and yield of potato in Golmud area were measured under different treatments. The results showed that the utilization rate of nitrogen fertilizer planted in potatoes was 38.6%, the utilization rate of phosphorus fertilizer was 9.2%, and the utilization rate of potassium fertilizer was 52.3%. In the application of nitrogen 220.00 kg/hm2, the application of phosphorus 158.50 kg/hm2, and the application of potassium 81.30 kg/hm2, the production was relatively high.
