摘要
对窝孔轮式排种器和槽孔轮式排种器油菜精量穴播机做了田间性能对比试验,分析播种空穴率、种子破碎率、穴粒数合格率、播种深度合格率。试验结果表明,两种穴播机播种空穴率、播种深度合格率、穴位错孔率结果相近;窝孔轮式排种器对种子破碎率高于槽孔轮式排种器;槽孔轮式排种器穴播机的穴粒数合格率优于窝孔轮式排种器穴播机。根据试验结果分析,对不同种植要求提出建议使用机型。
Comparative field experiment of two types of precision hill-seeder was implemented,empty whole rate,seeds crushing rate,qualified rate of seeds number,qualified rate of seeding depth were analyzed.The results showed that empty hole rate,qualified rate of seeding depth,and plastic-film holes dislocation rate were approximate;the crushing rate of was higher than the rate of slot wheeled metering device;the seeds number qualified rate of slot wheeled metering device was better than the rate of special-shaped hole seed metering device.Series of suggestion for available seeder type that satisfy different planting requirements were proposed.
