Description

Technical Field

[0001] This invention belongs to the agricultural field and relates to methods for raising and transplanting crop seedlings, particularly a method for raising and transplanting scallion strips. Background Technology

[0002] Scallions, a biennial herbaceous plant belonging to the genus Allium in the family Liliaceae, are a common vegetable in daily life. Currently, there are two main methods for cultivating scallions: one is to sow seedlings in late autumn and transplant them manually or mechanically in May or June of the following year; the other is to cultivate seedlings in seed trays in greenhouses in early spring and transplant them mechanically in May or June. Existing scallion transplanting methods, which involve planting individual scallion seedlings manually or mechanically, suffer from slow transplanting speed and high labor requirements. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide a method for raising and transplanting scallion seedlings in strips and blocks. The method is characterized by employing precise seeding and strip cutting techniques to combine multiple scallion seedlings with a seedling substrate via crop roots to obtain strip-shaped seedling pots. These seedling pots serve as transplanting units to complete the overall transplanting of multiple scallion seedlings. The specific steps include the following: A. Precision sowing: On a level plot of land with sufficient base fertilizer, use furrowing or hole pressing to precisely sow the treated scallion seeds into the sowing furrow or hole, cover with a layer of fine soil to complete the precision sowing. The row spacing is 2-4 cm and the plant spacing is 4-10 cm, depending on the requirements of the scallion variety. B. Check and replant seedlings: After the scallions emerge and before transplanting, check the growth of the scallion seedlings in a timely manner, remove weak seedlings, and transplant healthy seedlings into the missing areas to ensure that the seedlings are full and strong. C. Ridging and Furrowing: Rotary tillage and ridge preparation are carried out on the scallion planting plots, with a ridge spacing of 50-80 cm and a ridge bottom width of 8-20 cm; scallion transplanting furrows are dug along the center line of the ridge bottom, with a width of 3-6 cm and a depth of 10-20 cm; D. Strip cutting: Along the vertical direction of the planting row, use a long shovel to make the initial division of the seedling plot, with a division width of 20-60 cm, depending on the size of the transfer tray; along the direction of the planting row, use a strip seedling pot cutter with strip grids to cut the roots of the scallion seedlings to a depth of 3-6 cm, cutting the scallion roots together with the seedling substrate from the seedling plot to obtain strip seedling pots. Each strip seedling pot is long and strip-shaped, composed of multiple scallion seedlings and seedling substrate. The seedling substrate is connected and fixed together by the roots of the scallion seedlings to form a relatively stable seedling pot block; E. Strip Transplanting: Mechanical transplanting involves placing the scallion strip-shaped seedling pots, obtained through strip cutting, into specialized strip-shaped seedling trays. A strip-shaped transplanting machine is then used for the transplanting operation. The scallion strip-shaped seedling pots slide out of the trays and are conveyed sequentially into the transplanting trenches prepared in step C via the machine's conveying mechanism. An appropriate amount of soil is then added, completing the mechanized transplanting operation. Manual transplanting involves placing the scallion strip-shaped seedling pots, obtained through strip cutting, into ordinary seedling trays. Long tongs are then used to manually remove the scallion strip-shaped seedling pots from the ordinary seedling trays and place them sequentially into the transplanting trenches prepared in step C. An appropriate amount of soil is added, completing the manual transplanting operation.

[0004] The beneficial effects of this invention are as follows: The method for raising and transplanting scallion seedlings in strips according to this invention adopts a precise sowing method and cuts strip-shaped seedling pots into ordinary seedling plots through a cutting method to complete the strip-shaped seedling raising work; the seedling substrate in the strip-shaped seedling pots is rich in nutrients, which replaces fertilization during strip-shaped transplanting and achieves the purpose of fertilization; the strip-shaped seedling pot contains multiple scallion seedlings, which can realize the simultaneous transplanting of multiple scallion seedlings and improve transplanting efficiency.

[0010] The following diagram further illustrates the specific implementation process of the scallion strip seedling raising and transplanting method.

[0011] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present invention discloses a method for raising and transplanting scallion seedlings in strips. On a typical seedling plot 1, precise sowing and strip cutting are used to combine multiple scallion seedlings 8 with the seedling substrate through the crop root system to form strip-shaped seedling pots 12. These strip-shaped seedling pots 12 serve as transplanting units to complete the overall transplanting of multiple scallion seedlings 8. The specific steps include: A. Precision sowing: such as Figure 1 As shown, on the seedling plot 1 that has been fertilized with sufficient base fertilizer and leveled, the sowing furrows 2 or sowing holes 3 are evenly arranged on the seedling plot 1 by means of trenching and pressing holes. The treated scallion seeds 4 are precisely sown into the sowing furrows 2 or sowing holes 3, and covered with a layer of fine soil to complete the precision sowing. The row spacing is 2-4 cm and the plant spacing is 4-10 cm, which is determined according to the requirements of the scallion variety. B. Check and replant seedlings: After the scallions emerge and before transplanting, check the growth of the scallion seedlings in a timely manner, remove weak seedlings, and transplant healthy seedlings into the missing areas to ensure that the seedlings are full and strong. C. Ridging and furrowing: such as Figure 2 As shown, rotary tillage and ridging are carried out on the scallion planting plots, with a ridge spacing of 50-80 cm and a ridge bottom width of 8-20 cm; transplanting furrows 6 are dug along the center line of the ridge bottom 5, with a width of 3-6 cm and a depth of 10-20 cm. D. Strip cutting: such as Figure 3 As shown, along the vertical direction of the planting row, a long shovel 7 is used to initially divide the seedling plot 1, with a division width of 20-60 cm, determined according to the size of the transfer seedling tray; along the direction of the planting row, a strip seedling pot cutter 9 with strip grids is used to cut the scallion seedlings 8 from the root, with a depth of 3-6 cm, cutting the scallion roots together with the seedling substrate from the seedling plot 1 to obtain strip seedling pots 12. Each strip seedling pot 12 is long and strip-shaped, and is composed of multiple scallion seedlings 8 and the seedling substrate. The seedling substrate is connected and fixed together by the root system of the scallion seedlings 8 to form a relatively stable seedling pot block; E. Strip transplanting: such as Figure 4 As shown, the left side illustrates mechanical transplanting (the transplanting machinery is omitted here). Strip-shaped seedling pots 12, obtained through strip cutting, are placed into dedicated strip-shaped seedling trays 10. A strip-shaped transplanting machine is used for transplanting. The strip-shaped seedling pots 12 slide out of the strip-shaped seedling trays 10 and are conveyed sequentially into the transplanting trenches 6 prepared in step C via the machine's conveying mechanism. An appropriate amount of soil is then added, completing the mechanized transplanting operation. The right side illustrates manual transplanting. Strip-shaped seedling pots 12, obtained through strip cutting, are placed into ordinary seedling trays 11. A long clamp (the long clamp is omitted here) is used manually to remove the strip-shaped seedling pots 12 from the ordinary seedling trays 11 and place them sequentially into the transplanting trenches 6 prepared in step C. An appropriate amount of soil is then added, completing the manual transplanting operation.

[0012] The method for raising and transplanting scallion seedlings in strips as described in this invention is not limited to scallions alone, but can also be applied to rice, wheat, rapeseed, scallions, bok choy, celery, coriander and other densely planted crops with small plant spacing for strip seedling raising and transplanting operations.
