The vertical liner movement unit of multi-claw for sorting and transplanting unit 5 drives k seedling picking claws 6 moving vertically, the horizontal liner movement unit of multi-claw for sorting and transplanting unit 5 drives k seedling picking claws 6 moving horizontally above the feeding units for the source tray 8 and the feeding units target tray 1, during the horizontally movement of k seedling picking claws 6, the expansion unit in multi-claw for sorting and transplanting unit 5 drive the center distance of seedling picking claws 6 adjacent changed the hole distance p1 of the source tray 10 to the hole distance p2 of the target tray 9. The transportation route E is constituted of the vertical and horizontal movement of seedling picking claws 6, the transportation route E is located in the vertical movement plane of multi-claw H.

[0032] As shown in FIG. 2 and FIG. 3, during the horizontal lateral transfer process of k seedling picking claws 6 grip seedlings from the source tray 10 to the target tray 9, and go through the seedling picking zone A, seedling monitoring zone B, seedling discarding zone C and seedling releasing zone D, the source tray 10 of the feeding units for source tray 8 is located in the seedling picking zone A, the monitoring module 7 is located in the seedling monitoring zone B, the discarding seedling tray bin 2 is located in seedling discarding zone C, the target tray 9 of feeding unit for target tray 1 is located in the seedling releasing zone D.

[0034] As shown in FIG. 4, tray hole in first row the source tray 10 along to the feeding direction v is used as source area for single-claw replanting F; the hole in the tray of the source tray 10 except first row along to the feeding direction v is used as the source area for multi-claw transplanting G.

[0035] As shown in FIG. 5, every plug seedling is consisted of the seedling plant 11 and the seedling lump 12.

[0036] By using the invention that full-automatic system of integrated sorting-transplanting-replanting to realize automatic system of integrated sorting-transplanting-replanting operation are as followings:

[0037] (1) The multi-claw for sorting and transplanting unit 5 drives k the seedling picking claws 6 to pick k seedlings from the first row of the source area for multi-claw transplanting G along the feeding direction v of the source tray 10.

[0038] (2) Driven by the multi-claw for sorting and transplanting unit 5, k seedling picking claws 6 grip k seedlings to move along the transportation route E in the vertical movement plane of multi-claw H. When the k seedlings gripped by k seedling picking claws 6 pass the seedling monitoring zone B firstly, the monitoring module 7 monitor the k seedlings to detect all the non-ideal conditions, including the absence of seedling lump 12, the damage of seedling lump 12, the absence of seedling plant 11, the unhealthiness of seedling plant 11 and the damage of seedling plant 11 successively.

[0039] (3) Driven by the multi-claw for sorting and transplanting unit 5, k seedling picking claws 6 grip k seedlings to move further along the transportation route E in the vertical movement plane of multi-claw H. When k seedlings gripped by k seedling picking claws 6 pass the seedling discarding zone C, the detected seedlings which have any of the above-mentioned non-ideal conditions will be discarded in the discarding seedling tray bin 2. As a result, the non-stop sorting and transplanting of multiple seedlings is realized.

[0040] (4) Driven by the multi-claw for sorting and transplanting unit 5, k seedling picking claws 6 grip k seedlings to move further along the transportation route E in the vertical movement plane of multi-claw H. When k seedlings gripped by k seedling picking claws 6 pass the seedling releasing zone D, the multi-claw for sorting and transplanting unit 5 drives k seedling picking claws 6 to finish the placing of k seedlings to the target tray 9. Since the number of rows (m.sub.1) of the source tray 10 and the number of rows (m.sub.2) of the target tray 9 are both integral times of the number of seedling picking claws 6, m.sub.2n.sub.2/k times of placing is needed to fill all the holes (row m.sub.1line n.sub.2) of the target tray 9.

[0041] (5) In each cycle of the multi-claw transplanting, missing of seedlings in holes of the target tray 9 will happen when there is any above-mentioned non-ideal conditions for seedlings gripped by k seedling picking claws 6. According to the monitoring results of the monitoring module 7, the serial numbers of tray holes for the target tray 9 will be obtained.

[0042] (6) In the meantime of multi-claw for sorting and transplanting drive k seedling picking claws (6) to operate multi-claw transplanting, the single-claw for replanting unit (4) picks seedlings from the source area for single-claw replanting (F) to replant them into the tray holes that miss seedlings, according to the serial numbers of tray holes obtained from the target tray (9).
