摘要: 在生物炭与有机菌肥配施条件下,研究植烟土壤在生长期内土壤基础养分和可溶性碳(DOC)、氮(DON)含量的变化,为植烟土壤的合理施肥提供理论依据。采用田间试验的方法,在施相同化学肥料的基础上,设置CK(不施有机肥)、T1(生物炭)、T2(有机菌肥)、T3(生物炭菌肥)、T4(50%有机菌肥+50%生物炭)、T5(60%有机菌肥+40%生物炭)、T6(40%有机菌肥+60%生物炭)7个处理。结果显示,各有机肥处理与对照相比对提高土壤养分含量作用明显,与其他处理相比,T2处理显著提高了移栽后60 d的土壤铵态氮含量;T5处理则显著提高了整个生育期的硝态氮含量;与其他处理相比T5处理显著提高了60 d速效磷含量,T2处理显著提高了60 d时土壤速效钾含量。T1和T3处理与其他处理相比显著提高了旺长期(移栽后60 d)土壤DOC含量,T3处理的DOC/SOC比值达到最高(8.31 mg/g)。T2处理土壤DON含量在90 d达到最高(57.09 mg/kg),T5处理的土壤DON含量则在60 d最高(97.98 mg/kg);与其他处理相比,T3、T4、T5和T6处理降低了移裁后90 d植烟土壤成熟期的芳香化指数(AI),提高了E2/E3值。综上所述,在豫中烟区,有机菌肥及60%有机菌肥配施40%生物炭施肥措施,最有利于提高土壤氮素含量,生物炭和生物炭菌肥施肥措施有利于提高土壤可溶性碳含量。

Abstract: A field experiment was conducted to study the effect of compound-organic-bio-bacteria-fertilizer or/and biochar on soil properties and dissolved soil N and C in the tobacco-growing soil.Seven treatments were set as:①no organic fertilizer (CK),②biochar(T1),③Compound-organic-bio-bacteria-fertilizer (COBBF, T2),④Bio-bacteria-biochar-fertilizer(T3),⑤50% COBBF+50% biochar(T4)⑥60% COBBF+40% biochar(T5),⑦40% COBBF+60% biochar(T6). The result showed the soil nutrient was significantly improved under treatments with organic fertilizer application.The ammonium nitrogen content under T2 treatment was significantly promoted after tobacco transplanted 60 d compared with other treatments.The nitrate nitrogen content under T5 treatment was improved in the whole growth stage. The soil available potassium content under T2 and the soil available, phosphorus under T5 treatments were increased after tobacco transplanted 60 d compared with other treatments.The DOC content and DOC/SOC were obviously promoted under T1 and T3 treatments compared with other treatments, the highest DOC/SOC ratio as 8.31 mg/g occurred under T3 treatment. The DON content under T2 treatment peaked as 57.09 mg/kg after tobacco transplanted 90 d, while which reached as 97.98 mg/kg under T5 treatment during tobacco transplanted 60 d; Aromaticity index (AI) was reduced under T3,T4,T5 and T6 treatments. The E2/E3 was increased during tobacco transplanted 90 d. In conclusion, in central area of Henan Province, it is suggested that the COBBF only and 60% COBBF+40% biochar application were the optimal practice to improve soil N content;while biochar only and Bio-bacteria-biochar-fertilizer application could improve the soil dissolved C.
