| 摘 要： | 中国南方双季稻区秸秆资源丰富,但秸秆还田与耕作制度的最佳组合方式目前尚不明确。通过连续3年的田间定位试验(2013—2015年),研究秸秆还田条件下不同耕作方式对双季稻产量及土壤肥力质量的影响。试验处理包括翻耕与秸秆不还田(CT)、翻耕与秸秆还田(CTS)、旋耕与秸秆还田(RTS)和免耕与秸秆还田(NTS)。结果表明:与CTS处理相比,CT和NTS处理早稻平均产量分别降低3.5%和5.2%,晚稻平均产量分别降低3.6%和6.4%,其中,NTS处理晚稻产量显著低于CTS处理(p0.05);与CTS处理相比,RTS处理早稻和晚稻平均产量分别增加6.1%和3.1%。秸秆还田条件下土壤有机碳(SOC)、全氮(TN)、有效磷(AP)和速效钾(AK)均呈增加的趋势,其中,2015年CTS、RTS和NTS处理SOC、TN、AP和AK显著高于CT处理。与CT处理相比,NTS处理土壤容重(BD)增加4.9%(p0.05),CTS和RTS处理BD分别降低4.1%和5.2%,其中RTS处理显著低于CT处理。与CT处理相比,秸秆还田下CTS、RTS和NTS处理土壤p H分别降低1.9%、1.5%和2.5%,其中,CTS和NTS处理显著降低。CT处理土壤肥力质量呈下降的趋势,秸秆还田条件下各处理土壤肥力质量均呈提高的趋势,其中,2015年RTS处理分别高于CTS、NTS处理16.4%和80.4%。由此可见,在南方双季稻区,与常规翻耕和免耕相比,秸秆还田条件下,采用长期旋耕的方式能够进一步提高土壤肥力质量和水稻产量。
