Abstract Variation of culturable microbial population structure and essential soil enzyme activities were investigated with continuous cucumber cropping.The results indicated that culturable microbial population gradually decreased with continuous cucumber cropping.Bacteria showed a greater decrease trend in population than actinomyces and fungi.The decrease of bacterial population in rhizosphere and bulk soil reached a significant level when the third and the fourth cucumber crop were planted.The number of actinomy...
