摘要
[目的]为油菜创高产提供科学施肥依据。[方法]通过"3414"完全试验,比较不同施肥水平下产量水平,得出最高产量施肥配方的N、P、K处理。[结果]应用数学函数法分析产量结果,得出最佳施肥量N 240 kg/hm2、P2O582.5 kg/hm2、K2O 90 kg/hm2,最佳理论产量2 640kg/hm2。[结论]综合土壤测试值、产量、产投比以及补充地力损失等因素认为生产上推荐施用量:N 240 kg/hm2、P2O5120 kg/hm2、K2O 90 kg/hm2。
[Objective] The aim was to provide a scientific fertilization basis for high yield of Brassica capestris L..[Method[ The production levels with different fertilizer were compared, by ＂3414＂ full test, for obtaining N, P, K treatment with the highest yield. [Resultl The yields results were analyzed by mathematics function method, and the optimum amount of fertilizer N 240 kg/hm2, P205 82.5 kg/hm2, K20 90 kg/hm2 was given. The best theoretical yield was 2 640 kg/hm2.[Conclusionl Considering the soil test value, yield, output ratio and loss of soil fertility and other factors supplementary, the recommended fertilizer in production were N 240 kg/hm2, P2Os 120 kg/hm2, K20 90 kg/hm2.
