摘　　要：为增加有机质、氮、磷、钾等土壤养分,提升耕地质量总体水平,加大粪肥、有机肥施用量,提高抛撒效率及抛撒均匀性,研究了双圆盘式抛撒机作业速度、抛撒盘转速、排肥口开度3个因素对抛撒效率、抛撒均匀性的影响。试验结果表明:影响抛撒效率的因素主次顺序为作业速度>排肥口开度>抛撒盘转速,最优组合为作业速度6 km/h、排肥口开度70%、抛撒盘转速90 r/min;影响抛撒均匀性的因素主次顺序为作业速度>抛撒盘转速>排肥口开度,最优组合为作业速度6 km/h、抛撒盘转速120 r/min、排肥口开度70%。综合分析得知,抛撒作业速度是抛撒效率和抛撒均匀性的最大影响因素。In order to increase organic matter,nitrogen,phosphorus,potassium and other soil nutrients,improve overall level of cultivated land quality,increase application amount of manure and organic fertilizer,improve throwing efficiency and throwing uniformity,effects of three factors on throwing efficiency and throwing uniformity,namely,operating speed of double disc spreader,speed of throwing disc,and opening of fertilizer outlet,were studied.Test results showed that factors affecting throwing efficiency were operating speed>opening of fertilizer outlet>speed of throwing tray.Optimal combination was operating speed 6 km/h,opening of fertilizer outlet 70%,and speed of throwing tray 90 r/min.Factors affecting throwing uniformity were operation speed>speed of throwing tray>opening of fertilizer outlet.Optimal combination was operation speed 6 km/h,speed of throwing tray 120 r/min,and opening of fertilizer outlet 70%.Through comprehensive analysis,it was known that speed of throwing operation was the biggest factor affecting throwing efficiency and uniformity.
