Based on three general evaluation methods for no-tillage corn seeder, i.e. performance testing, tracing experiments and user surveys, this paper introduced a quantitative evaluation method to analyze the applicability of no-tillage corn seeder. After weighting and evaluating index were determined, by evaluating against different work sites in a certain area and calculating applicability of weight and evaluating index with different levels, a rational comprehensive evaluation on the applicability can be provided accordingly.
