不同有机物料对枸杞园土壤物理性质的影响

Effect of Different Organic Materials on Soil Physical Properties in the Chinese Wolfberry of Garden

以“宁杞1号”为试材，研究了糠醛渣、生物有机肥、腐殖酸、秸秆、羊粪5种有机物料施入土壤5a后对土壤含水率、土壤容重、孔隙度、水稳性团聚体等物理性质的影响。结果表明：施羊粪时提高土壤含水率最有效；糠醛渣对降低土壤容重、增加孔隙度最有效；生物有机肥能够提高0．25～5min土壤水稳性团聚体的含量。

Taking ＇Ningqi No.1＇ as material, the different organic materials into the soil after 5 years, soil moisture content-bulk density, porosity and water stability of aggregates were analyzed, such as changes in physical properties based on the field experiment. The results showed that sheep dung could improve soil moisture content effectively; furfural slag could reduce the soil bulk density and increase the porosity effectively; biological organic fertilizer could improve soil aggregate content of water stability of o. 25-5 mm.
