增施沸石和有机肥对砂质农田春玉米土壤CO2排放和产量的影响
Effects of adding zeolite and organic fertilizer on CO2 emissions and yield of spring maize in sandy soil
摘要
Abstract
The respective characteristics and synergistic effects of zeolite and organic fertilizer application on crop yield,soil CO2 emissions and carbon balance were explored to provide a basis for establishing an efficient farmland management model for carbon sequestration and yield increase in sandy soil of North China.The micro-plot experiment was conducted on maize in the sandy soil of Daxing district,Beijing city.Five treatments were set up,including no fertilization(CK),conventional fertilization(T1),adding zeolite(T2),adding organic fertilizer(T3),adding zeolite and organic fertilizer(T4).Soil CO2 emissions,maize yield,soil carbon balance and their influencing factors under different treatments were systematically studied.The results showed that compared with T1 treatment,maize yield was significantly increased by 18.25%in T4 treatment.In the early stages of maize growth and after fertilization,the soil CO2 emission rates of each treatment showed a fluctuating trend of first increasing and then decreasing.The cumulative CO2 emissions of soil(CE)showed as T3>T1>T4>T2>CK,compared with T1 treatment,the CE of T2,T4 and T3 treatments were decreased by 9.44%,2.39%and increased by 6.78%,respectively;compared with T2 treatment,CE of T3 treatment was significantly increased by 15.19%.Compared with T1 treatment,ecosystem carbon balance and soil carbon sequestration potential were significantly increased by 15.13%,25.45%,and 17.97%,19.92%in T2 and T4 treatments,respectively;however,the crop carbon emission rates was significantly reduced by 20.93%and 22.73%,respectively.Relevant analysis showed that T4 treatment decreased the cumulative CO2 emissions,increased maize yield and biomass by increasing soil moisture,NH4+-N,NO3--N,available potassium,available phosphorus,microbial biomass carbon and nitrogen content.Therefore,adding the application of zeolite and organic fertilizer could be used as a suitable farmland management model for carbon sequestration and yield increase of spring maize in sandy soil of North China.关键词
