摘  要：
[目的]探讨花生秸秆源生物黑炭在赣东北地区花生种植中的合理用量。[方法]设4个处理,即对照(不施黑炭)、BC_(20)(20 t/hm2黑炭)、BC_(30)(30 t/hm~2黑炭)、BC_(40)(40 t/hm~2黑炭),研究不同处理下花生产量、土壤有机质、碱解氮、有效磷、速效钾和p H的变化。[结果]施用生物黑炭可显著提高花生产量和土壤有机质、碱解氮、有效磷、速效钾养分含量,与对照相比,BC_(20)、BC_(30)和BC_(40)的花生产量分别提高了12.90%、21.40%和26.80%,土壤有机质含量分别增加了13.90%、18.45%和27.97%,碱解氮含量分别增加了21.58%、43.15%和118.05%,有效磷含量分别提高了28.21%、56.87和74.07%,速效钾含量分别增加了22.57%、36.51%和46.97%;土壤p H分别提高2.62%、4.04%和7.32%,且随着生物黑炭用量的增加,花生产量和土壤肥力呈逐渐增加趋势。[结论]在赣东北地区施用生物黑炭可提高花生产量,较好地阻控红壤酸化。

摘  要：
[Objective] To find reasonable rate of biochar from peanut straw in northeastern Jiangxi Province.[Method] Setting up 4 treatments:CK( no biochar);BC_(20)( 20 t/hm~2biochar);BC_(30)( 30 t/hm~2biochar);BC_(40)( 40 t/hm~2biochar),the changes of peanut yield,soil organic matter,p H,available nitrogen,phosphor and potassium contents,in different treatments were analyzed.[Result] The results showed that:the application of biochar could improve significantly peanut yield,soil organic matter and available nitrogen,phosphor and potassium.Compared with CK,peanut yields in BC_(20),BC_(30) and BC_(40)were increased by 12.9%,21.4% and 12.9%,respectively;soil organic matter contents were increased by 13.90%,13.90% and 13.90%,respectively;soil alkaline hydrolysis nitrogen contents were increased by21.58%,43.15% and 21.58%,respectively;soil available phosphorus contents were increased by 28.21%,56.87 and 74.07%,respectively;soil available potassium contents were increased by 22.57%,36.51% and 22.57%,respectively.Soil p H values were increased by2.62%,4.04% and 7.32%,respectively.Meanwhile,peanut yield and soil fertility were improved gradually with increasing of application rates of the biochar.[Conclusion] The application of biochar in northeastern Jiangxi can improve peanut yield,effectively prevent and control red soil acidification.
