摘　　要：为了制定正确的油松种子园施肥技术方案提供理论依据,我们在陕西洛南古城种子园进行了油松种子园施肥技术研究试验。本试验采用不同施肥方案,按照正交设计L_(9)=3^(4),采用N、P、K(3种)肥料和施肥方式为变量因素,每个因素3个梯度。通过不同的方法进行了分析,结果表明:N(0.50 kg)、P(1.00 kg)、K(0.20 kg)和施肥方式辐射型的结合最佳,获得的雌球花量最多。施肥方式的选择是油松种子园的施肥的关键,肥料对雌球花量影响由高到低依次为K>N>P。In order to provide technical support to the fertilizer program of Pinus tabulaeformis seed orchard,experiment with fertilizer use for Pinus tabulaeformis seed orchard was carried out in Luonan seed orchard of Shaanxi.The experiment applied different fertilization treatments for research using orthogonal design L_(9)=3^(4)method.Field experiment was conducted with four factors at 3 levels each.The results showed that N(0.50 kg),P(1.00 kg),K(0.20 kg)and radiative fertilization method combined achieved the best,with the female flowers most in quantity.The key is the choice of fertilizer application method on Pinus tabulaeformis seed orchard.The effect of fertilizer on female flowers followed the order K>N>P.
