摘　　要：为探讨南方丘陵区芝麻种植过程中合理的有机培肥措施,通过不同用量的秸秆和生物黑炭还田试验,研究了其对芝麻产量以及土壤pH值、有机质和氮磷钾养分含量的影响。结果表明:与常规施肥相比,秸秆和生物黑炭处理的芝麻籽粒产量分别增加了42.7%~89.0%和75.6%~118.3%,秸秆产量分别增加了24.2%~39.3%和43.6%~61.9%;同时,施用秸秆或生物黑炭可以较好地改良土壤酸化情况,并提升土壤有机质和速效氮磷钾的含量,且生物黑炭的效果优于秸秆直接还田;在试验设置的用量范围内,生物黑炭施用量越大,作物增产幅度和土壤肥力提升幅度越高。To explore reasonable patterns of organic fertilizer in the sesame planting in southern area China,one field experiment wasconducted which included different rates of straw and biochar,grain yield,soil pH,organic matter and nutrient contents were analyzed.Theresults showed that:compared with conventional fertilization,straw and biochar could improve grain yield of sesame by42.7%-89.0%and75.6%-118.3%respectively,straw yield was increased by24.2%-39.3%and43.6%-61.9%separately.Meanwhile,the application of strawor biochar can decrease soil acidification,improved soil organic matter and available nutrient contents,moreover,the effect of biochar wasbetter than straw.The grain yield and soil fertility increased when biochar was applied more in the range of the experiment settings.
