摘要[目的]探讨微生物肥料“宁盾”粉剂在叶菜类作物上的最佳使用剂量及其促生效果。[方法]选取不同剂量的微生物肥料“宁盾”粉剂在叶菜类作物上进行温室试验，并在此基础上开展田间试验。[结果]温室试验结果表明，“宁盾”处理组能显著提高叶菜类作物的出苗率、叶片数、鲜干重、叶绿素含量等指标，最佳剂量为 5.0 g/千粒；在田间小区试验中，与空白对照组相比，“宁盾”粉剂不仅能够增加叶菜类作物产量，达35.09%，还能显著提高可溶性蛋白、维生素C含量，且较“宁盾”水剂100倍液的效果好。[结论]微生物肥料“宁盾”粉剂不仅能够促进叶菜类作物生长，增加产量，还能提高其品质。

Abstract[Objective]To discuss the optimal dosage of biofertilizer “Nanjing Shield” powder in leafy vegetable， and to research the growth promoting effect.[Method]A range of dosages of biofertilizer “Nanjing Shield” powder were used on leafy vegetables in greenhouse test and field test.[Result]Compared with the control treatment， the biofertilizer “Nanjing Shield” powder significantly promoted several growth indexes of leafy vegetables， such as the emergence rate， leaf number， chlorophyll content， and fresh and dry weight. According to the results of the greenhouse test， the optimal dosage of the powder on leafy vegetables was 5.0 g per thousand seeds. The field test showed that the powder significantly enhanced the yield of leafy vegetables， and the contents of vitamin C and soluble protein.[Conclusion]Biofertilizer “Nanjing shield” powder not only promotes the growth and yield of leafy vegetables， but also improves its quality.

根围促生细菌作为一类具有代表性的促生细菌，现已被越来越多的研究及应用；随着农业的发展以及人们对农用微生物的研究，单一的菌株及单一功能的微生物制剂已不能满足现代农业的需要，因此，复合多功能微生物菌剂及其多种剂型的微生物产品已成为现代农业发展的趋势[1-4]。

杨春悦[5]研究表明，新型生物复混肥的施用可以促进青菜生长，且微生物菌肥不仅在一定程度上影响生菜根际土壤的营养成分、理化性质、土壤酶活性以及土壤中微生物种群的数量，还可以改良土壤pH，有效提高土壤中硝态氮、有效磷、有效钾及有机质的含量。另外，有些微生物肥料易与农家有机肥混合施用，对甘蓝有促生长作用；……
