Abstract

Abstract: 【Objective】To ascertain the difference of the accumulation of soil organic carbon (SOC) in paddy and upland soil, the mineralization, dissolved organic carbon (DOC) and microbial biomass carbon (MBC) in soil under different soil moisture conditions were determined. 【Method】 In laboratory, one portion of paddy and upland soil was incubated under 45%, 60%, 75%, 90% and 105% water holding capacity (WHC) to measure the mineralization of SOC. The other portion was incubated under 45%, 75% and 105%WHC to measure the DOC and MBC content in soil. All the soils were placed at 25℃，100% air humidity for 100 days.【Result】The soil moisture, land use (paddy and upland) and the interactions of them all had significant effects on the mineralization of SOC, content of soil DOC and MBC. The accumulative mineralized proportion (amount) of SOC increased as moisture content increased from 45% to 90%WHC in paddy soil and from 45% to 75%WHC in upland soil. Meanwhile, the half decay time of SOC (paddy, 5.23-7.57 age; upland, 6.79-12.87 age) decreased as moisture content increased. During 100 d incubation period, the equivalent of 2.33%-3.94% and 1.66%-3.33% of SOC in paddy and upland soil respectively, were mineralized. Both the mineralization rate of SOC in paddy and upland soil were greater under flooding condition than under aerobic condition. However, the content of DOC and MBC in paddy soil were lower under flooding condition.【Conclusion】Along with the increasing of soil moisture content, from 45%-90%WHC in paddy soil and from 45%-75%WHC in upland soil, the mineralization of SOC will be accelerated, thereby the soil nutrient release will be expedited. Nevertheless, the increase in soil moisture has no positive-effects on the DOC and MBC content of soil. The reasons, why the mineralization rate and the accumulative mineralization proportion (amount) of SOC were higher under flooding condition or in paddy soil than under aerobic condition or in upland soil, may be that the decomposition of SOC be accelerated by the alternation of drying and wetting of soil, and the priming effects of the alternation of drying and wetting on the paddy soil are greater than that on the upland soil.
