Effects of Antagonistic Microbes and Organic Fertilizer Mixtures on Growth and Quality of Cucumber

Microbial organic fertilizer was developed to tackle or control long-time monocropping disorder for cucumber in soil to increase soil productivity and cucumber quality. Different concentrations and ratios of antagonistic microbes,Bacillus subtilis and Aspergillus effusus Tiraboschi,mixed with chicken-based fermented organic fertilizer were investigated to control long-time monocropping for cucumber in soil.Results showed microbial organic fertilizer can substitute chemical fertilizer for cucumber growth in requirements for nutrients. Microbial organic fertilizer inhibited wilt incidence of cucumber,the incidence rate was decreased by 47. 4%- 69. 6 % and 58. 7%- 57. 6 % compared to treatments in CK and chemical fertilizer. Furthermore,microbial organic fertilizer greatly raised the content of Vc and soluble sugar in cucumber fruit and deeply reduced the content of NO-3in cucumber. Compared to treatment of chemical fertilizer,the optimal microbial organic fertilizer was the combinations of Bacillus subtilis 108cfu / g and Aspergillus effusus Tiraboschi viable spore 105cfu / g with application rate of500 g per plant,Vc and soluble increased by 66. 3 and 31. 9 % respectively,while the nitrate declined by 95 %.
