摘要： 通过田间试验研究大白菜氮磷钾肥料效应，建立福建省三明市辖区大白菜养分丰缺指标及其施肥指标体系。试验表明：试验地基础地力贡献率为39.22%~83.75%，大白菜施用氮、磷、钾肥料增产率分别为28.50%、5.33%和9.05%，其增产效果为N＞K＞P。当地大白菜土壤碱解氮、有效磷和速效钾养分含量高的临界指标分别为260、42、172 mg/kg；低的临界指标分别为188、12、66 mg/kg。当地大白菜最高产量施氮量为(287.71±77.50) kg/hm2，氮磷钾施肥配比为1:0.09:0.84；最佳经济产量施氮量为(274.52±75.92) kg/hm2，氮磷钾施肥配比为1:0.07:0.85。

Abstract: By studying NPK fertilizer effect on Chinese cabbage in field experiment, the nutrient enrichment and paucity index and fertilization system in Sanming City were built. The results showed that: the contribution rate of soil fertility to Chinese cabbage was 39.22% to 83.75%, the growth rate of Chinese cabbage was 28.50%, 5.33% and 9.05% with the application of N, P and K, and the yield-increasing effect was N>K>P. The highest index of alkali-hydrolyzable N, available P and available K of local Chinese cabbage soil was 260, 42 and 172 mg/kg, respectively; and the lowest index was 188, 12 and 66 mg/kg, respectively. The maximum application rate of N for the local Chinese cabbage was (287.71 77.50) kg/hm2, the application ratio of NPK was 1:0.09:0.84; the N application amount with the best economic yield was (274.52 75.92) kg/hm2, and the application ratio of NPK was 1:0.07:0.85.
