Abstract:

Experiment was carried out in typical black soil area of Harbin, and investigated the correlativity of soybean yields, root weight, SPAD value of soybean leaf and NPK contents in soybean plant under different fertilization modes, and the greenhouse gas (CO2¡¢N2O and CH4) emission during growth period The four treatments contend recommendation fertilization, reducing soil testing fertilization+C synergistic agent, slow release fertilization, recommendation fertilization + N staging regulation, recommendation fertilization was the control Results showed that the yield was increased highest of 7.2% by low release fertilization, low carbon effect was obvious with 1.8% yield increased and 30% N addition reduced by reducing soil testing fertilization+C synergistic agent The 100 seed weight order of four treatments was as followed recommendation fertilization + N stage regulation>slow release fertilization>recommendation fertilization>reduced fertilization The average CO2 fluxes of four treatments showed significant difference but the average fluxes of N2O and CH4 showed no significant differences Compared with CK treatment, reducing soil testing fertilization+C increased the chlorophyll content, promoted the growth of the plants and root, maintained good respiratory CO2 effect during the crop growth period, with yield increased of small amplitude The research results can be used as evaluation of soybean production capacity under different fertilization management measures and the theory basis of the correlation of plant growth and the environment
