摘要
采用"3414"肥料效应试验方案,研究了安徽省东至县油菜高产栽培的氮、磷、钾肥肥料效应,并建立了肥料效应函数模型。结果表明:项目区土壤氮、磷、钾供给能力达中等偏上水平,增施磷肥有利于提高油菜产量,而增施氮和钾肥增产效应并不显著;最佳经济施肥量为N24.53 kg/hm2、P2O577.65 kg/hm2和K2O 4.66 kg/hm2。
Using ‘3414＇ fertilizer effect experiment, the effect of nitrogenous （N）, phosphate （P）, potash （K） fertilizer on rape yield in Dongzhi County was researched. The function model of fertilizer effect was set up. The results showed that the supply capacity of N P K fertilizer were above the middle level, treatment of adding P fertilizer reached the best result to improve rape＇s yield, but the increase effect of using N K fertilizer were not significant. The optimum rate of N, P2O5 and K2O for rape were 24.53 kg/hm^2, 77.65 kg/hm^2 and 4. 66 kg/hm^2, respectively.
