不同肥料种类和配比对葫芦巴产量的影响

Effects of Different Fertilizers and Application Rates on Yield of Trigonella foenum-graecum

为提高葫芦巴的生物产量以及籽粒产量,采用L_9(3~4)正交试验设计,进行不同施肥种类和肥料最佳组合试验。结果表明:有机肥、氮肥、磷肥和钾肥4个因素对葫芦巴生物产量的影响为磷肥>有机肥>氮肥>钾肥,对葫芦巴籽粒产量影响为磷肥>氮肥>有机肥>钾肥;经方差分析和多重比较,试验条件下,葫芦巴最高生物产量和籽粒产量的最佳施肥组合为施用有机肥400kg/667m^2、磷肥17kg/667m^2、钾肥7.5kg/667m^2。

To enhance the biomass and grain yield of T. foenum-graecum, the effects of different fertilizers and application rates on yield of T. foenurrrgraecum were studied by using orthogonal design L9 （34）. Results. The order of the four factors on biomass was phosphatic fertilizer）organic fertilizer） nitrogenous fertilizer〉potash fertilizer, the order of the four factors on grain yield was phosphatic fertilizer 〉nitrogenous fertilizer〉organic fertilizer〉potash fertilizer. The variance analysis and multiple comparison indicated the optimum combinations to gain higher yield in the test were organic fertilizer 400kg/667m2 , phosphatic fertilizer 17kg/667m2 ＋potash fertilizer 7.5 kg/667m2.
