| 摘 要： | 通过氮磷钾3414大田试验,研究了河北二季作春播马铃薯氮磷钾养分吸收规律及肥料适宜用量。结果表明：优化施肥情况下生产1 000kg马铃薯所需N、P、K量分别为4.78、0.47、4.64kg;马铃薯苗期N、P和K吸收速率分别为583.0、43.7和500.4g/(hm2·d),苗期至开花期分别为686.6、116.2、1 105.8g/(hm2·d),开花期至收获期分别为3 900.2、373.9和3 426.4g/(hm2·d),马铃薯开花后是养分吸收的关键时期;优化施肥情况下,马铃薯养分吸收量和吸收速率是不施肥处理的2倍以上。本试验条件下,N、P2O5和K2O适宜用量分别为186、86和212kg/hm2。

| Abstract: | The nutrient absorption and suitable quantity of spring potato were studied through fertilizer effect. An experiment was conducted by using of "NPK 3414" in Hebei double cropping cultivated region. The results showed: requirement of nitrogen (N), phosphorus (P), and potassium (K) for production of 1 000kg potato under optimized fertilization and the amount of NPK were 4.78, 0.47, and 4.64kg, respectively. The absorption rate of N, P, K were 583.0, 43.7, 500.4g/(ha·d) at potato seedling stage, and 686.6, 116.2, 1 105.8g/(ha·d) from seedling to blooming stage, and 3 900.2, 373.9, 3 426.4g/(ha·d) from blooming to harvesting stage, respectively. The key period of potato nutrient absorption was after blooming. The nutrient absorption rate under optimized fertilization treatment was more twice times than that of non-fertilization treatment. The recommended rate of N, P2O5 and K2O was 186, 86 and 212kg/ha in the present experiment condition. |
