| 摘 要： | 主要以引进的柔性曲面挤压式排种器为研究对象.采用正交旋转组合试验研究该排种器的工作参数一前进速度v、转动速度n对各行行内播种均匀性变异系数v<,1>、各行行间播种一致性变异系数v<,2>、总播种量稳定性变异系数V与破损率A的影响,通过DPS 9.50数据处理系统进行数据分析建立了数学模型,并进一步对数学模型进行分析.分析结果表明,v和n的变化对v<,1>,v<,2>:V的影响均极显著(P<0.01),在а=1%的水平上两因素各影响因子均极显著(P<0.01),而破损率A在试验过程中始终为0.从回归方程中得出两因素取值范围内各试验指标的变动范围:v<,1>为[3.5848,6.2446],v<,2>为[1.3608,3.5882],V为[0.6452,3.4790].

| Abstract: | This article mainly takes the flexible flat-friction seed-metering device imported as the research object.The effect rules of the two working parameters,such as motion velocity(v),rotate velocity(n),on the CV of seeding uniformity in the lines(v1),the CV of seeding consistency between the lines(v2),the CV of seeding rate stability(V)and breakage rate(A) are analyzed by the two factors quadratic orthogonal rotational combination experimental design.With DPS 9.50 data processing system these mathematical mode... |
