Furrowing opener is one of important components in seeding and fertilizing. They often work in the soil with high moisture content. Soil adhesion on the surface of furrow opener increase the drag resistance considerably, makes the opened furrow irregular and depth of furrow not uniform, influences the performance of seed and, sometimes, makes them stop working. All these phenomena will influence the seeding quality.
开沟器是播种机、施肥机上的重要部件，在含水量较大的土壤中工作时，土壤粘附在工作表面，改变了表面形状，导致牵引阻力增大，开出的沟形不整齐，使种子在沟中的深度不一致，影响播种质量，严重时使出苗率降低10%，甚至使其无法作业。
