中文摘要	为了探究不同生物炭基肥施用量下水分胁迫对花生栽培的应用潜力,运用自动遮雨棚花生盆栽试验,对不同生物炭基肥施用量(0,750,1 500 kg/hm~2)和不同水分胁迫程度(常规控水,70%~75%田间持水量;中度水分胁迫,60%~65%田间持水量;重度水分胁迫,50%~55%田间持水量)对花生产量、耗水和其养分吸收特征的影响进行研究。结果表明:施入750,1 500 kg/hm~2生物炭基肥可提高015 cm土层土壤铵态氮和速效钾含量、植株地上部分氮钾养分吸收和水分生产率;除重度水分胁迫外,其他两种控水水平均能提高土壤速效钾含量,促进植株营养吸收,进而提高产量;中度水分胁迫下,施入750,1 500 kg/hm~2生物炭基肥,较无生物炭基肥可显著提高植株地上部分氮钾吸收,增产40.48%和37.71%,提高水分生产率53.8%和9.9%。研究结果可为生物炭基肥在干旱地区花生生产的应用方面提供理论依据。
英文摘要	In order to evaluate the application potential of water stress on peanut cultivation under different application amounts of biochar-based fertilizer,pot experiments were conducted in automatic canopy tanks to determine the effects of different application amounts of biochar-based fertilizer(0,750,1 500 kg/hm~2)and different water stresses(conventional water control,moderate water control,heavy water control,corresponding soil water contents were 70%~75%,60%~65% and 50%~55% of field capacity,respectively)on peanut yield,water consumption and nutrition absorption characteristics.The results showed that applying biochar-based fertilizer by 750 and 1 500 kg/hm~2 could increase the contents of ammonium nitrogen and available potassium in the top 15 cm soil,nitrogen and potassium absorption of above-ground plant as well as water productivity.Except heavy water control treatment,soil available potassium content,plant nutrition uptake and peanut yield were all increased in the other two water control treatments.In the treatment of moderate water control,compared with the treatment without biochar-based fertilizer,treatments of applying biochar-based fertilizer by 750 and 1 500 kg/hm~2 could significantly increase the above-ground nitrogen and potassium uptake,increase peanut yield by 40.48% and 37.71%,and increase water productivity by 53.8% and 9.9%,respectively.These results could provide theoretical basis for the application of biochar-based fertilizer in peanut cultivation in arid area.
