研究生物黑炭和有机肥配施化肥对旱地作物种植和养分损失的影响,旨在进一步探索高温多雨的南方丘陵地区旱地作物合理施肥和高产高效种植以及资源优化利用的有效途径.采用田间小区试验,设置了5个处理:不施肥(CK)、单施化肥(CF)、化肥+生物黑炭(CF+B)、有机无机肥配施(OF+CF)和有机无机肥配施且添加生物黑炭(OF+CF+B),探讨了生物黑炭和有机肥施用对春玉米产量、地表氮磷径流损失、作物氮磷肥料利用率的影响.结果表明:生物黑炭或有机肥的施用可显著增产8.2％～11.1％,但有机肥和生物黑炭结合施用增产效果最佳,增产率可高达13.79.相比CF处理,CF+B处理可显著降低15.9％的氮素径流损失和24.2％磷素径流...

Based on chemical fertilizer application,we studied effects of combining application biochar and organic fertilizer on crops planting and nutrients loss in dryland,which aimed to further explore the effective ways of rational fertilization,high yield and high efficiency planting and the optimal utilization of resources in dry land crops under the conditions of high temperature and precipitation in the hilly region of southern China.Field plot experiments were conducted to investigate the effects of biochar and organic fertilizer on maize yield,nitrogen-phosphorus loss derived by surface runoff...
