Study on the Performance Evaluation Method of Wheat No-Tillage Planter Based on Gray Theory

Abstract:

No-tillage planting is one of the most important assignments of the conservation tillage technology. The 2BMF-9 wheat no-tillage planter was taken as object，the planting experiment on field were carried out on eight kinds of surface treatments, then various performance indices, emergence of seeding rate and tiller number were obtained on each surface treatment. The grey correlation analyzing concluded that the seeding uniformity, covering soil ability and passing ability had greatly influenced the emergence of seeding rate and tiller number. Eight kinds of surface treatments were categorized with the principle of gray clustering evaluation.
