| 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N 24.53 kg/hm2、P2O577.65 kg/hm2和K2O 4.66 kg/hm2.

| Abstract: | 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/hm2,77.65 kg/hm2 and 4.66 kg/hm2,respectively. |
