摘　　要：采用玉米秸秆炭与化学肥料、改性菌糠等原料,通过亲水性单体溶液吸附粘合制备生物炭基缓释复合肥。在经过为期1年的田间比较试验,对施加生物炭基缓释复合肥种植鲜食玉米的产量和节支效益进行分析。田间肥效试验结果表明,以CK组常规种植施肥量与产量进行比较,处理(3)在减施30%追肥尿素的情况下,生物炭基缓释复合肥料在稳定试验玉米产量的基础上,能够达到减肥增效和节约生产成本的目的。Biochar based slow release compound fertilizer was prepared by adsorption and adhesion of corn straw charcoal,chemical fertilizer and modified fungus bran with hydrophilic monomer solution.The yield and cost-saving benefits of fresh food maize planted with biochar based slow-release compound fertilizer were analyzed through a one-year field comparison experiment.The results of field fertilizer efficiency experiment showed that,compared with the fertilizer application amount and yield of CK group,under the condition of reducing the application of 30%urea in treatment 3,the biochar slow-release compound fertilizer could achieve the purpose of reducing the weight and efficiency and saving the production cost on the basis of stabilizing the experimental corn yield.
