摘  要:
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/hm~2, the application of phosphorus 158.50 kg/hm~2, and the application of potassium 81.30 kg/hm~2, the production was relatively high.
