摘　　要：[目的]针对过量施用化肥引起菠菜产量和品质下降的现象,研究增施微生物菌肥对菠菜产量及品质的影响。[方法]通过施用不同梯度的微生物菌肥,分析其对菠菜产量及品质等方面的影响。[结果]化肥与微生物菌肥的配合施用促进了菠菜产量提升;但加大微生物菌肥用量,产量未呈现线性增加;施用微生物菌肥的菠菜根系长度变短、植株高度明显增加、叶片草酸含量下降、粗纤维含量和叶绿素含量增加;施用化肥后菠菜的硝酸盐含量较未施用任何肥料的菠菜明显增加,增施1500、2250 kg/hm^(2)微生物菌肥后硝酸盐含量没有明显增加,但增施3000 kg/hm^(2)微生物菌肥后硝酸盐含量再次出现明显增加。[结论]微生物菌肥能够改善菠菜品质,但用量的增加与品质的关系不是线性增加的趋势,应避免盲目增加微生物菌肥用量。[Objective]The aim was to study the effect of increasing microbial fertilizer on the yield and quality of spinach in view of the decrease of yield and quality of spinach caused by excessive application of chemical fertilizer.[Method]The effects of different gradients of microbial fertilizer on the yield and quality of spinach were analyzed.[Result]The combined application of chemical fertilizer and microbial fertilizer promoted the increase of spinach yield.However,the yield did not increase linearly with the increase of the amount of microbial fertilizer.The root length of spinach treated with microbial fertilizer was shortened,the plant height was significantly increased,the oxalic acid content in leaves was decreased,and the crude fiber content and chlorophyll content were increased.The nitrate content of spinach after application of chemical fertilizer was significantly higher than that of spinach without any fertilizer.The nitrate content did not increase significantly after application of 1500 and 2250 kg/hm^(2)microbial fertilizer,but the nitrate content increased significantly again after application of 3000 kg/hm2 microbial fertilizer.[Conclusion]Microbial fertilizer could improve the quality of spinach,but the relationship between the increase of dosage and the quality was not a linear increase trend,and the blind increase of microbial fertilizer dosage should be avoided.
