摘　　要：针对温室大棚施肥作业机械化程度低的问题,研究设计了一款固态有机肥与复合肥混合施肥机,通过排肥稳定性试验、排肥均匀性试验、排肥断条率试验和田间试验验证施肥机的效果。结果表明,有机肥、复合肥排肥量稳定性变异系数分别为4.12%、0.28%;有机肥、复合肥排肥量均匀性变异系数分别为2.61%、3.61%;有机肥、复合肥在施肥均匀性试验区段内均不存在无肥料区段,施肥机断条率0%,满足国家标准要求。田间试验的有机肥土壤混合比例平均值10.22%、上层有机肥颗粒比例平均值13.94%、下层有机肥颗粒混合比例平均值6.50%,旋耕后能够实现土肥混合效果。To address issue of low mechanization in greenhouse fertilization operations,a specialized spreader was designed for dispensing a mix of solid organic fertilizer and compound fertilizer.Effectiveness of this machine was validated through a series of tests,including evaluations of fertilizer discharge stability,uniformity,breakage rate,and practical field assessments.Results showed that variation coefficient for stability of organic fertilizer and compound fertilizer discharge was 4.12%and 0.28%,respectively.Variation coefficient for uniformity of fertilizer application for organic fertilizer and compound fertilizer was 2.61%and 3.61%,respectively.There was no fertilizer free section for organic fertilizer and compound fertilizer in fertilization uniformity test section,and breakage rate of fertilizer applicator was 0%,which met national standard requirements.Average ratio of organic fertilizer soil mixture in field experiments was 10.22%,average ratio of organic fertilizer particles in upper layer was 13.94%,and average ratio of organic fertilizer particles in lower layer was 6.50%,indicating that soil fertilizer mixing effect coula be achieved after rotary tillage.
