山地小型玉米播种机粒距变异系数的试验分析

The Small Mountain Corn Planter Grain Test Distance Coefficient of Variation Analysis

山地小型玉米播种机是丘陵山地玉米全程生产机械化的一个重要装备,玉米播种机的播种粒距变异系数是衡量玉米播种器播种精确性的重要指标。运用GB/T 6973—2005单粒(精密)播种机试验方法,在田间进行生产性试验播种,获得几组粒距数据,通过图形分析和数据分析并计算,验证播种器性能,这一研究方法对丘陵山地如何选择小型玉米播种机具有一定的指导意义。

The small mountain corn seeding machine is an important equipment of hilly corn whole production mechanization,corn seed spacing variation coefficient is an important index to measure the planter seeding accuracy,this paper uses GB/T6973—2005 single particle（precision） method of drill test, production test in the field into the row sowing, get several groups of seed spacing through the analysis of data,graphical analysis and data and calculation,to verify the performance of seeder,this study method of hills and how to choose small corn planter has very important directive significance.
