Abstract

In order to obtain the efficient fertilization patterns for maintaining soil fertility, this research adopted the field experiments to investigate the effects of eight different fertilization patterns on the soil microbial biomass carbon and nitrogen (SMBC, SMBN) in the wax gourd- pepper crop rotation system of Hainan in China. The results showed that the concentrations of SMBC and SMBN were all significantly increased in the treatments of mixed application of chemical fertilizer and organic fertilizer and the treatment of single application of organic fertilizer(p<0.05). And compared with the treatment of single application of organic fertilizer, only the two treatments of mixed application of 100% chemical fertilizer and organic fertilizer and mixed application of 75% chemical fertilizer and organic fertilizer could significantly increase the concentrations of SMBC and SMBN. However, there was no significant difference between the two treatments (p>0.05). It can be concluded that the treatment of mixed application of 75% chemical fertilizer and organic fertilizer can effectively increase and maintain the SMBC and SMBN, and it is an efficient fertilization pattern to maintain soil fertility in wax gourd- pepper crop rotation system.
