Study on Transplanter With Chute and Seedling Aid Springs(PartⅡ)——Judging Targets System for Transplanters

Base on the designing and testing of transplanter with chute and seedling aid springs, a judgingtargets　system and evaluation methods was presented. The system performance, including uniformity, state of seedling transplanted, productivity, adaptability to soil and seedling and automaticity, were investigated. The performance indexes of the assembly machine of transplanting and watering, filmcovering or/and fertilizing were also discussed in this paper.
