Disclosed are a seedling transplanting and sorting pickup system for plant trays and seedlings, comprising a conveying and separating device, a seedling sorting device and a seedling pickup device. The seedling sorting device is arranged in an upper position in the middle of the conveying and separating device and at a starting end of the seedling pickup device. The seedling pickup device comprises a transmission assembly and a plurality of seedling pickup belt-holding devices (9). The seedling sorting device comprises a plurality of groups of seedling sorters (3) adjacent to a first belt wheel (2). The seedling sorters (3) are arranged in the same central plane as the first belt wheel (2) of the seedling pickup device. The conveying and separating device comprises a conveying assembly (6) and a plant tray guider (8) for separating plant trays and seedlings. The plant tray guider (8) is fixedly arranged under the seedling pickup belt-holding devices (9) and is adjacent to an end of the conveying assembly (6). The seedling transplanting and sorting pickup system for plant trays and seedlings is simple in structure, adopts the most fundamental conveying system, and conforms to the features of plant trays and seedlings. Seedling pickup is fast and clean, seedlings are intact and not damaged, and high transport efficiency is achieved.La présente invention concerne un système de collecte de transplantation et de tri de semis pour bacs et semis de plantes, comprenant un dispositif de transport et de séparation, un dispositif de tri de semis et un système de collecte de semis.
