摘要：

为了研究秋大白菜的合理施肥量，以秋大白菜品种87-114为研究对象，采用“3414”最优回归试验设计方案，氮、磷和钾的常规施肥分别为360 kg/hm2、180 kg/hm2和180 kg/hm2。结果表明：试验区基础地力为86.3%，3种肥料的贡献率为K>N>P。利用一元二次肥料效应方程确定最佳肥料施用量氮肥(N)为334 kg/hm2，磷肥(P2O5)为106 kg/hm2，钾肥(K2O)为140 kg/hm2，氮、磷、钾的比例为2.39:0.9:1。“3414”试验可以确定大白菜生产中氮、磷和钾的施用量，同时在现有的地力条件下可适当降低3种肥料的施用量。

Abstract:

The aim was to study the rational fertilization of autumn cabbage 87-114. Field experiments was carried out with "3414" design of the optimal regression test, the conventional fertilization of nitrogen, phosphorus and potassium were 360 kg/hm2, 180 kg/hm2 and 180 kg/hm2. The results showed that based fertility test area was 86.3%, three fertilizer contribution rate of K>N>P. Fertilizer recommended rates were stimulated by the models of one-factor. The results indicated that the optimum fertilizer rates of nitrogen (N), phosphorus (P2O5) and potassium (K2O) were 334 kg/hm2, 106 kg/hm2 and 140 kg/hm2 respectively. The ratio of nitrogen, phosphorus and potassium was 2.39:0.9:1. "3414" test could determine nitrogen, phosphorus and potassium application and reduce the three fertilizer application under the existing conditions of soil fertility.
