Abstract: For solving the problems existing in loose leaf purchasing, such as high investment, short of professional graders, and lower grading skills, the experiments on a new loose leaf purchasing system involving harvest and curing by stalk position and grading by curing barn were carried out. The results showed that through introducing a harvesting license system, specialized curing and household pre-inspection and other measures, the new purchasing system not only retained the advantages of the original loose leaf grading and purchasing system, but also realized scientific harvest by stalk position, sewing green leaves after classification, cured leaves sorting (removing greenish and variegated leaves), marking and bundling leaves from the same stalk position and curing barn, and purchasing by whole barn. The results of application indicated that the new system improved grading quality, increased qualified rates, and expedited the process of leaf grading and purchasing.
