育种小麦精密排种器排种性能的试验研究

Test Research on Seed Release Performance of Precision Wheat-seed Metering Device

在分析单粒精密播种机工作性能要求的基础上，对自行设计的小麦育种用气吹式排种器进行排种性能的分析与试验，找出了影响排种器排种性能的主要因素及其工作范围。采用优化试验设计方法，对其排种性能进行优化试验，建立了各指标的数学模型，并对各因素影响效应进行分析，找出了能满足排种性能要求的最佳工况值。

Based on the analysis of working performances of the precision drill, and the teston the seed release performance of blowing-type metering device, the ma jor factors affectingthe seed release performance and the working scope are obtained. By means of optimumexperiment design, the mathematical models of the major factors are obtained. The effects ofeach factor are analysed to find the optimum working condition fitting the requirments ofseed release performance.
