【摘要】[目的]为阐明混合接种蚯蚓及植物促生根际细菌技术在蔬菜生产中的作用.[方法]采用室内盆栽试验的方法,研究接种蚯蚓、植物促生根际细菌(固氮细菌和钾活化细菌)对甘蓝生长的影响以及甘蓝对氮和钾的吸收.[结果]7种接种方式均明显促进了甘蓝根上部分的生长,其中混合接种蚯蚓、固氮细菌和钾活化细菌处理下甘蓝根上部分生物量最大.5种接种方式(接种蚯蚓、双接蚯蚓和固氮细菌、双接蚯蚓和钾活化细菌、双接钾活化细菌和固氮细菌以及混合接种)下甘蓝地上部分氮的吸收量在0.05水平显著高于对照.[结论 混合接种方式是一种有潜力的生物技术,可以用来减少蔬菜生产中化肥的施用量.%[ Objective ] The research aimed to clarify the roles of mixed inoculation of earthworm and plant growth-promoting rhizobacteria ( PGPR) on the growth of vegetables. [ Method ] A serials of pot trials were conducted to investigate the single, dual or triple inoculation of earthworms or PGPR, including nitrogen-fixing bacteria ( NFB) ( Azotobacter chroococcum PDSN-5)
and
potassium-solubilizing
bacteria
(KSB)
(Bacillus
mucilaginous PDSK-1) , on the growth of Chinese kale (Brassica juncea) and on uptake of N and K in the plant. [ Result] All of the seven inoculation treatments apparently increased the shoot growth of B.
