摘要: 以红壤性水稻土长期定位试验为对象,采用田间调查结合室内测定方法研究不同施肥处理下红壤性水稻土的物理结构状况及其透气特征。结果表明:1) 与不施肥(Control)相比,长期单施氮肥(N)处理对土壤容重、孔隙率以及土壤透气性均无显著影响(p > 0.05);2)氮磷钾配施(NPK)以及2倍氮磷钾配施(2NPK)仅对土壤容重以及非毛管孔隙率影响显著(p < 0.05),但对土壤透气速率的影响未达显著水平(p > 0.05);3) 相关分析结果表明土壤透气速率与水稻产量存在显著相关关系,而有机肥无机肥配施(NPKOM)不仅能够显著降低土壤容重,增加土壤孔隙,同时还能改良土壤通透性。
Abstract: In the present study, soil samples derived from quaternary red clay were taken and analyzed from long-term fertilization experiment under rice cropping systems. The purposes were to analyze the effects of long-term different fertilization managements on the soil structural characteristics and soil gas permeability. The results showed that: 1) compared with those of no fertilization control (Control), little impacts of soil bulk density, soil porosity and soil gas permeability were observed in the treatment N (p > 0.05); however, 2) application NPK and 2NPK significantly decreased soil bulk density and increase soil macropores (p < 0.05), but had little effect on soil gas permeability; at last 3) significant positive correlation was observed between soil gas permeability and rice yield, and application of NPK plus organic amendments (NPKOM) not only decreased soil bulk density and increase soil macropores, but improved soil gas permeability (p < 0.05).
