摘　　要：为研究不同修复材料对设施土壤的修复效果,设置有机肥(T1)、玉米秸秆段(T2)、玉米秸秆段+微生物菌剂(T3)3种不同修复材料和不施加修复物(CK),先在非种植状态下修复30 d,然后定植黄瓜,持续修复至拉秧,测定其对设施土壤理化性状和酶活性的影响。结果表明,不同修复材料对设施土壤理化性状及酶活性均有影响。修复30 d,T1处理的土壤pH和EC值较对照显著降低,土壤有机质、速效氮、有效磷、脲酶、碱性磷酸酶和蛋白酶含量显著增加。修复115 d,T3处理的土壤pH和EC值显著降低,0~10 cm土壤有机质、速效氮和速效钾含量分别较对照增加17.42%、41.13%和46.69%,10~20 cm土壤有机质、速效氮和速效钾含量分别较对照增加35.61%、48.82%和69.16%,显著增加了土壤过氧化氢酶、淀粉酶和蔗糖酶活性。综合各项指标,修复期内,3种材料对设施土壤的修复效果表现为T3>T1>T2。In order to study the effect of different remediation materials on greenhouse soil,three different remediation materials,namely organic fertilizer(T1),corn stalk segment(T2),corn stalk segment+microbial agent(T3)and no remediation(CK),were set up in this experiment.First,they were remediated for 30 days in the non-planting state,then cucumber was planted in the field,and the effects on physical and chemical characteristic and enzyme activities of greenhouse soil were measured.The results showed that the physical and chemical characteristic and enzyme activities of the soil were affected by different restoration materials.After 30 days of restoration,T1 treatment significantly decreased soil pH and EC values,and significantly increased soil organic matter,available nitrogen,available phosphorus,urease,alkaline phosphatase and protease contents.After 115 days of remediation,T3 treatment significantly reduced soil pH and EC values.Soil organic matter,available nitrogen and available potassium in 0-10 cm increased by 17.42%,41.13%and 46.69%respectively compared with the control,and soil organic matter,available nitrogen and available potassium in 10-20 cm increased by 35.61%,48.82%and 69.16%respectively,which was significant.According to the comprehensive indexes,the restoration effect of facility soil was T3>T1>T2 during the restoration period.
