不同肥料种类和配比对葫芦巴产量的影响

摘要

为提高葫芦巴的生物产量以及籽粒产量,采用L9(34)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400 kg/667m2、磷肥17 kg/667m2、钾肥7.5 kg/667m2.%To enhance the biomass and grain yield of T.foenum-graecum,the effects of different fertilizers and application rates on yield of T.foenum-graecum 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.
